Quick Answer — At $949, the Riding'times GT54 fits a 2,000 W peak rear hub motor, 290 N·m and a removable 48 V pack of 1,296 Wh into a 106.5 lb mini dirt bike with footpegs. Held at Limited Mode's 15.5 mph cap on the throttle, that pack carries a 180 lb rider about 61 miles across level pavement.
At 20 mph the same charge covers about 46 miles, and at 10 mph up a steady 4% grade it lasts about 21. Riding'times prints 62 miles in its headline strip and 60 on a badge lower on the page; the range section works out your own ride from speed, gear, climbing, load, temperature and tires.
Its box list names no pedals, and its top gear reaches 40 mph by the product page's figure, so it sits outside the federal e-bike definition, which begins with "fully operable pedals"; the class section sets out where that leaves it.
On September 26, 2026 our store listed the GT54 as orderable at $949, with $1,999 shown as the regular price. Delivery is free anywhere in the contiguous United States, and warranty claims start with our US support desk.

How we verified this Riding'times GT54 review
Every figure here was read on September 26, 2026 from Riding'times' GT54 product page, its product record, the Riding'times FAQ, two of its blog posts on the GT54, its warranty page, our listing, or the statutes quoted in the class section. The range and fit figures are computed, and each of those sections ends with its formula and a source for every input.
This is a specification-verified review: each figure was checked against the manufacturer's published specification and recomputed, and the range model reproduces the road-cycling benchmark it rests on. We sell the GT54, so weigh the red flags as carefully as the green.

Read September 26, 2026 from the GT54 product page, its product record, the FAQ and Riding'times' launch post of July 31, 2025. Where two Riding'times documents disagree on one item, the row prints both.
The Riding Times GT54: a 2,000 W mini electric dirt bike with footpegs
Riding'times names it the "GT54 Electric Mini Dirt Bike for Teenagers and Adults", under the line "2000W Peak Power • 48V 27Ah Removable Battery • Compact Mini Electric Dirt Bike". Its FAQ on the same page calls the GT54 "a compact mini electric dirt bike with 2000W peak power and a removable 48V 27Ah battery."

The left side: the orange inverted fork at the front, the pack inside the frame's cradle, the rear disc and its red caliper, and the bench seat running back to the tail light.
The product record describes the rider it has in mind: "The Riding'times GT54 is designed for riders looking for a compact and versatile electric bike that makes outdoor adventures simple and enjoyable." Lower down it adds: "Rather than focusing solely on performance numbers, the GT54 emphasizes riding enjoyment and accessibility."
Put next to its own specification, that approachable description sits on a 2,000 W peak motor and a 40 mph top gear. The page lists "neighborhood riding, gravel paths, packed dirt, campgrounds and permitted recreational riding areas" as its ground; whether a particular street, trail or campground will have it is the class question.

From the front, right side: the handlebar and display over the number plate with its orange graphics, the kickstand down, and the knobby front tire on its orange rim.
The rider's feet go on footpegs. Riding'times' box list names the bike, the front wheel, the front fender, the front axle, the charger, the manual and the wrenches, and its FAQ sets the GT54 and GT54 Pro apart from the four models it lists as "equipped with pedals". Riding'times' own photographs show a cleated footpeg bolted to the rear of the frame's lower cradle.

The footpeg close up: a cleated black platform on a folding mount at the rear of the frame cradle, with the pack behind it and the swingarm to the left.
One Riding'times document reads differently. Its blog post of May 27, 2026 on pedal conversions says: "The GT54 is a little different, since it comes with pedals but no chain, so it is not set up as a traditional pedal-drive bike." Either way, nothing turns the rear wheel on the GT54 except its motor, and the class section takes that up.
If a peg bends or wears, Riding'times sells replacements as "E-Bike Foot Pegs for Riding'times GT54 / GT73 Series", and we stock them in our Riding'times parts collection. Parts are final sale on our store, so we check the version that fits your GT54 before the order goes in.
GT54 or GT54 Pro?
On the GT54's page, Riding'times prints the same tires, brakes, lights and geometry for both models; the Pro costs $350 more on our store and moves to a 60 V system with more peak power, more torque and a larger pack:
| GT54 | GT54 Pro | |
|---|---|---|
| Motor | "Peak 2000W" | "Peak 3000W" |
| Torque | 290 N·m | 338 N·m |
| Battery | 48 V 27 Ah, 1,296 Wh | 60 V 25 Ah, 1,500 Wh |
| Controller, specification tables | 48 V 32 A | 60 V 40 A |
| Charger | 54.6 V 3 A | 67.2 V 3 A |
| Throttle gears | 16, 22 and 40 mph | 16, 28 and 50 mph |
| Front suspension, specification tables | "All-aluminum Barrel Axle Inverted Fork" | "Front Hydraulic Double Wishbone Suspension with Adjustable Damping" |
| Weight | 106.5 lb | 102.5 lb |
| Computed, 15.5 mph on the throttle, 180 lb rider | 61 mi | 66 mi |
| Price on our store | $949 | $1,299 |
The GT54 vs GT54 Pro table on Riding'times' GT54 page, each model's specification table and our two listings, read September 26, 2026; the GT54 Pro's own page prints gear 1 as 15 mph for both. The computed row is this site's range model run on each bike's published figures. Our GT54 Pro review covers the Pro in the same depth.
The FAQ on the GT54's page states the step directly: "The GT54 uses a 2000W peak motor and 48V battery platform, while the GT54 Pro moves to a 3000W peak configuration and 60V battery platform with upgraded hardware."
GT54 or GT73?
The GT73 is the full-size machine: pedals in the box, 19-inch wheels, two packs and a 330 lb max load, for $550 more.
| GT54 | GT73 | |
|---|---|---|
| Pedals | footpegs; the box list names no pedals | yes, in the box |
| Wheels | 60/100-14 front, 60/100-12 rear | 70/100-19 front and rear |
| Battery | one 48 V 27 Ah pack, 1,296 Wh | two 48 V 18.2 Ah packs, 1,747 Wh |
| Weight | 106.5 lb | 116 lb |
| Max load | 220 lb | 330 lb |
| Rider height, geometry block | 4'2" to 5'9" | 5'5" to 6'3" |
| Computed, 15.5 mph on the throttle, 180 lb rider | 61 mi | 83 mi |
| Price on our store | $949 | $1,499 |
Each machine's specification table and geometry block on Riding'times' product pages, and our two listings, read September 26, 2026; our GT73 review covers the full-size machine.
Riding'times' page draws the line by size: the GT54 "uses a compact, dirt-bike-inspired platform that is smaller and easier to maneuver than the full-size GT73 family."
Will the GT54 fit you?
The GT54's seat does not adjust, and on Riding'times' own photograph its lowest point stands 30.2 inches off the ground, so your inseam sets how a stop feels: seated, 66 of 100 riders at 5'4" and 95 of 100 at 5'6" put both feet flat, and every surveyed rider from 5'9" up does.
Those numbers come from setting 6,068 bodies from the US Army's 2012 anthropometric survey against Riding'times' published dimensions and its side-profile photograph of the GT54. With footpegs in place of a crank there is no pedaling height to set, so the questions are your feet at a stop, your knees on the pegs and your arms at the bars.
Three measurements place you:
- Measure your inseam. In socks, back to a wall, press a hardcover book up firmly between your legs and mark the wall at its top edge; the floor-to-mark distance is your inseam.
- Look up your row in the foot-down table, which counts how many of 100 riders your height put both feet flat with the seat at 30.2 inches and at 27.2.
- Measure the back of your knee. Sit on a firm chair with your thighs level and knees at a right angle, and measure from the floor to the crease behind the knee; the knee table sets that against the pegs.
Two rider windows come from Riding'times for the GT54: 4'2" to 5'9" in the product page's geometry block, and 140 to 185 cm (4'7" to 6'1") in its FAQ. Both sit beside the model's rows below. Below 5'0" the survey has too few bodies for a row of its own, so a rider that short should go by the three measurements above.
| What Riding'times publishes | Its figure | On its photograph |
|---|---|---|
| Rider height | 4'2" to 5'9" (geometry block); 140–185 cm (FAQ) | not measurable |
| Seat height | 27.2 in | 30.2 in at the seat's lowest point |
| Tail height | 31.1 in | 31.5 in |
| Pedal ground clearance | 11.0 in | the footpeg's top at 11.6 in |

The geometry drawing from the GT54's product page, shown with the eight figures listed beside it. Scaled by its own wheelbase line, the drawing's heights do not match those figures, so nothing on this page is measured from it.
Is it too small for you? Where your knees sit on the pegs
For most riders up to 6'2", no: the pegs sit 18.6 inches below the seat, deeper than the median rider's back-of-knee height at every height in the table, so the thigh rests level or slopes down to the knee; at 6'2", 67 of 100 riders still keep a level thigh.
Back-of-knee height is the survey's popliteal height, "the vertical distance from a footrest to the back of the right knee", measured as the subject "sits with the thighs parallel, the knees flexed 90°" (the survey's measurer's handbook, § 6.4.67). A seat that far above the footrest gives a level thigh and a right-angle knee; a shorter drop pushes the knee up.
On the GT54 the drop runs from the seat's lowest point on Riding'times' photograph, 30.2 inches off the ground, to the top of the footpeg at 11.6 inches. Seat and pegs both ride on the sprung frame, so as the suspension settles under you they drop together and the distance between them holds.
| Your height | Back of knee to floor, seated | Knee above a level thigh, median rider | Thighs level or lower, of 100 |
|---|---|---|---|
| 5'0" | 13.3–14.9 in | −4.5 in | 100 |
| 5'2" | 13.8–15.4 in | −3.8 in | 100 |
| 5'4" | 14.3–16.1 in | −3.3 in | 100 |
| 5'6" | 15.1–16.9 in | −2.7 in | 100 |
| 5'8" | 15.7–17.4 in | −2.0 in | 100 |
| 5'10" | 16.3–18.1 in | −1.4 in | 99 |
| 6'0" | 16.8–18.8 in | −0.8 in | 90 |
| 6'2" | 17.4–19.1 in | −0.2 in | 67 |
For each height: the 5th-to-95th-percentile spread of back-of-knee heights, how far the median rider's knee sits above a level thigh with the feet on the pegs, and the riders of 100 whose thigh sits level or slopes down; a minus sign puts the knee below the seat's line. Army survey bodies, men and women together.
Between 5'0" and 5'10", the median rider's knee sits 4.5 to 1.4 inches below the line of a level thigh. Above that the knee rises toward level, and a boot adds its sole to the figure: an inch of sole lifts the knee an inch.
Can I put a foot down at a stop?
It turns on your inseam and on which seat figure your bike matches: at the photograph's 30.2 inches, 27 of 100 riders at 5'2" put both feet flat and 95 of 100 at 5'6"; at Riding'times' printed 27.2 inches, 99 of 100 at 5'2" do. At a stop you stay seated astride, so the seat is the height your legs reach past.
The geometry block prints the seat at 27.2 inches. Scaled by the published 41.7-inch wheelbase, its side-profile photograph puts the seat's lowest point, where you sit, at 30.2 inches. Plan on 30.2 inches until you can sit on the bike yourself.
| Your height | Typical inseam | Flat-footed at 30.2 in, of 100 | At 27.2 in, of 100 |
|---|---|---|---|
| 5'0" | 27.1–29.7 in | 2 | 93 |
| 5'2" | 28.0–31.1 in | 27 | 99 |
| 5'4" | 29.1–32.2 in | 66 | 100 |
| 5'6" | 30.2–33.5 in | 95 | 100 |
| 5'8" | 31.1–34.3 in | 100 | 100 |
| 5'10" | 32.2–35.5 in | 100 | 100 |
| 6'0" | 33.2–36.7 in | 100 | 100 |
| 6'2" | 34.3–37.5 in | 100 | 100 |
How many of 100 riders at each height have an inseam at least as long as the seat is high, first at the 30.2 inches measured on Riding'times' photograph, then at the 27.2 its geometry block prints. The typical-inseam column is the survey's crotch height, 5th to 95th percentile.
Will I feel cramped, or stretched?
Compact and upright: every surveyed rider from 5'0" to 6'2" reaches the grips without leaning, with the median rider's elbows bent 74 to 85 degrees. The grips sit 12.0 to 13.4 inches ahead of the footpeg and 28.0 to 28.5 inches above its center, close to the seat, so the arms fold to meet them, a little more for the shortest riders.
In one study, twenty recreational cyclists rated the most upright of three trunk positions as the most comfortable (Priego Quesada et al., 2017); the GT54 sits every height in the table that way.
| Your height | Lean from upright, median rider | Riders who reach the grips sitting upright, of 100 | Elbow bend sitting upright, median rider |
|---|---|---|---|
| 5'0" | 0° | 100 | 74° |
| 5'2" | 0° | 100 | 76° |
| 5'4" | 0° | 100 | 78° |
| 5'6" | 0° | 100 | 80° |
| 5'8" | 0° | 100 | 82° |
| 5'10" | 0° | 100 | 83° |
| 6'0" | 0° | 100 | 84° |
| 6'2" | 0° | 100 | 85° |
For each height: how far the median rider tips forward from vertical to reach the GT54's grips, how many of 100 reach them without tipping at all, and the median elbow angle sitting straight. Every figure uses that body's own measured torso and arms, and the grip position taken from Riding'times' photograph.
How much weight goes through my wrists?
Very little: about 6 percent of your body weight at the median with your back relaxed. Ten road racers on the brake hoods in a laboratory put 15% of their weight on the bars (Carahalios, 2015); on the GT54's high, close grips the median rider's relaxed-back ceiling stays well under half of that at every height in the table.
On rough ground your hands still hold on through every bump, and "Protective gloves" appear on the safety list in Riding'times' FAQ.
| Your height | Share of your weight, back relaxed | Median rider's weight | On each hand |
|---|---|---|---|
| 5'0" | 6% (5–8%) | 126 lb | about 4 lb |
| 5'2" | 6% (5–8%) | 139 lb | about 4 lb |
| 5'4" | 6% (5–7%) | 147 lb | about 4 lb |
| 5'6" | 6% (5–8%) | 166 lb | about 5 lb |
| 5'8" | 6% (5–8%) | 179 lb | about 6 lb |
| 5'10" | 6% (5–8%) | 192 lb | about 6 lb |
| 6'0" | 6% (5–8%) | 204 lb | about 6 lb |
| 6'2" | 6% (5–7%) | 216 lb | about 7 lb |
A ceiling on the hands' share with the back relaxed, built from each body's segment weights (Clauser et al., 1969); the bracket spans the seat and grip positions measured on the GT54, and the pounds use the survey's median weight at each height.
How do I set it up when it arrives?
With a fixed seat and fixed pegs, setup is the front end. The box holds the front wheel, the front fender, a 236 × 15 mm front axle, two open-end wrenches marked "22#" and hex wrenches in 4, 5 and 6 mm, and Riding'times' FAQ lists the "Front wheel", the "Handlebars" and the "Front fender or accessories" among the parts you fit yourself.
The same FAQ adds: "Make sure all bolts and fasteners are properly tightened during assembly." Go round the axle, the handlebar clamp and the fender bolts again after the first few rides. If you would rather not assemble it, the FAQ suggests "seeking assistance from a local bike shop or qualified technician."
How we computed fit
Foot-down clearance is inseam minus the seat's height; the knee figure is back-of-knee height minus the seat-to-peg drop; lean is the smallest trunk angle at which a straight arm reaches the grip; hand load is the upper body's weight times its lean, divided by the reach to the grip.
Worked for a 5'8" rider with the survey's median 32.6-inch inseam and median 16.5-inch back-of-knee height: the inseam clears the 30.2-inch seat by 2.5 inches, and on the 18.6-inch drop the thigh slopes 2.0 inches down to the knee.

|---|---|---|---|
| overall length | 59.1 in | 61.0 in | +3.3% |

| overall length, spec table | 59.8 in | 61.0 in | +2.2% |
| overall height, spec table | 39.8 in | 40.7 in | +2.4% |
Every measurement takes its scale from the axle centers on Riding'times' GT54 side profile, set to the published 41.7-inch wheelbase; the spec table's 59.76 and 39.76 inches appear rounded to one decimal. Five of the seven checks land within 3.5 percent of the published figure. The geometry block's overall height and seat height do not, so the seat comes from the photograph and the foot-down table carries both seat figures.

Buy it, delivered freeA 2,000 W peak hub motor, 290 N·m and three speed gears
The specification table lists a "Peak 2000W Rear Hub Motor" with 290 N·m of torque, fed by a "48V 32A Controller", and the headline strip repeats "2000W Peak Power". A peak figure is what the motor gives in a short burst; Riding'times' launch post of July 31, 2025 calls the torque figure "Wheel Edge Torque".

The rear hub motor close up, inside the orange rim, with the spokes crossing its case and the rotor and red caliper in front of it.
The motor sits in the rear wheel, and the page's FAQ puts it simply: "The GT54 uses a rear hub motor that delivers electric power directly to the rear wheel." With no crank and no chain, the throttle is the only way you call on it.
Riding'times' FAQ sets out the speeds in two programs, and the product page prints its own figures for the three gears:
| Setting | Gear 1 | Gear 2 | Gear 3 |
|---|---|---|---|
| Limited Mode | 15.5 mph | 15.5 mph | 15.5 mph |
| Unlimited Mode, FAQ | 15.5 mph (25 km/h, ECO) | 28 mph (45 km/h, STD) | 39 mph (63 km/h, TURBO) |
| Unlimited Mode, product page | 16 mph | 22 mph | 40 mph |
Riding'times' FAQ, "What is the speed for each model?", and the GT54 vs GT54 Pro table on the GT54's product page, read September 26, 2026; the kilometer figures and the mile conversions are Riding'times'.
The FAQ explains that Limited Mode "is a speed-restricted riding mode designed to comply with local eBike regulations in many regions", and that with it on, "the maximum speed of the eBike is capped at 25 km/h (15.5 mph) regardless of the selected pedal-assist or throttle level."
At the top end the documents print two figures: "40 MPH" in the specification table and the headline strip, and 39 mph in the page title and in the FAQ's "2000W brushless motor , 39 mph max speed". The GT54 vs GT54 Pro table adds the conditions: "Load capacity of 143 lb measured at 40 MPH".

The cockpit from the seat: the display at the center of the bar, the switch pod with its mode buttons on the left, the ignition key on the right, and the red fork caps below.
One 48 V 27 Ah pack, 1,296 Wh
A 48 V pack of 27 Ah holds 1,296 watt-hours, which Riding'times' headline strip rounds to "1300Wh Battery". Its specification table names "21700 / 48V 27Ah Lithium Battery", and the page adds that "The removable design gives riders the flexibility to charge the battery on or off the bike." Riding'times' launch post puts the pack at "a neat 15lbs".
One charger comes in the box, 54.6 V at 3 A. At 3 A, putting 27 Ah back into an empty pack takes no less than about 9 hours, so you should plan on charging overnight.
Before you plug in, the FAQ asks you to check that "The battery power switch is turned OFF", that "The eBike is completely powered OFF" and that "The charger and charging port are clean and dry", and to use "the original charger supplied with the eBike."
For a long layup, the same FAQ recommends a charge between 40% and 60%, a dry indoor spot above 0°C (32°F), a top-up "every 1–2 months", and the pack off the bike where possible, warning that "Long-term storage with a fully depleted battery may reduce battery lifespan."
How far the GT54 goes on one charge
On level pavement a 180 lb rider gets about 61 miles from a full charge at 15.5 mph on the throttle, 46 at 20 mph and 40 at 22 mph, gear 2's cap on the product page. Up an 8% grade at 10 mph, a full pack covers 9 miles.
To estimate your own ride:
- Look up the speed you hold in the speed table, or the gear you ride in the gear table.
- Budget 223 to 288 Wh of the 1,296 for each 1,000 feet of climbing (10 mph on the throttle, 4 to 8% grades; the hills table).
- Adjust for your load and the air temperature, then plan on three quarters of the result.
Each table holds one steady ride at a time, computed from Riding'times' specification, Bafang's published figures for a comparable geared hub motor, drum measurements of knobby tires, the GT54's own tire size and a cycling-power model validated on an open road. The formula subsection walks one ride through every step.
Does riding faster cut range? Miles at each speed
On the flat, speed decides first: a full charge runs 84 miles at 10 mph and 27 at 28. From 15.5 to 20 mph the charge drops from 61 miles to 46, because the power the air takes grows with the cube of your speed.
| Speed, flat | Per mile | Full charge | With 25% kept |
|---|---|---|---|
| 10 mph | 15.3 Wh | 84 mi | 63 mi |
| 12 mph | 17.1 Wh | 76 mi | 57 mi |
| 15.5 mph | 21.1 Wh | 61 mi | 46 mi |
| 18 mph | 24.8 Wh | 52 mi | 39 mi |
| 20 mph | 28.2 Wh | 46 mi | 34 mi |
| 22 mph | 32.2 Wh | 40 mi | 30 mi |
| 25 mph | 39.1 Wh | 33 mi | 25 mi |
| 28 mph | 47.7 Wh | 27 mi | 20 mi |
Each row is a steady throttle ride on level pavement, a 180 lb rider in 77 °F air. The right-hand column keeps 25% of the 1,296 Wh in reserve, as the pedelec in Schmitt, Decker and Doppelbauer's test-bench study did to avoid deep discharge. Rows above 15.5 mph need Unlimited Mode, which the class section takes up; 28 mph is the FAQ's STD figure for gear 2.
Which gear should you ride in? Range by speed setting
The gear caps the pace, and the pace sets the range: Limited Mode gives about 61 miles, gear 1 at its 16 mph cap about 60, and gear 2 at 22 mph about 40. With nothing to pedal, the throttle does every mile, so the speed you hold, and the gear that caps it, decide what the pack delivers.
| Mode | Its speed cap | Full charge at the cap | With 25% kept |
|---|---|---|---|
| Limited mode | 15.5 mph | 61 mi | 46 mi |
| Gear 1 | 16 mph | 60 mi | 45 mi |
| Gear 2 | 22 mph | 40 mi | 30 mi |
Level pavement, a 180 lb rider, each setting held at the cap the product page prints. There is no gear 3 row: with that rider the model's comparable 1,000 W motor tops out near 28.6 mph on the flat, well short of the 40 mph Riding'times rates gear 3 at, so the model cannot price it. The FAQ's 28 mph for gear 2 is the last row of the speed table.
For cold days, Riding'times' FAQ gives advice that points the same way: "Use lower assist levels when possible".
Does going uphill drain the battery faster?
Yes, and harder the steeper it gets: at 10 mph on the throttle, each 1,000 feet the GT54 climbs on a 4 to 8% grade takes 223 to 288 Wh beyond what the same distance takes on the level. Only 38 to 48% of that goes into lifting you and the bike; the motor and the pack lose the rest, a share that grows as the grade does.
Rider and machine together come to 286.5 lb, 180 plus the GT54's 106.5, and lifting that much through 1,000 feet takes 108 Wh at the rear wheel on its own.
On an 8% grade at 10 mph the pack spends 324 Wh on each 1,000 feet, so the whole 1,296 Wh would lift you about 4,000 feet with nothing left for the flat. The model gives no credit for descents; coasting downhill costs less than the same distance on the level, so a budget built from these rows leaves a little spare.
| Grade | Per mile, throttle | Full charge, throttle |
|---|---|---|
| 2% | 36 Wh | 36 mi |
| 4% | 62 Wh | 21 mi |
| 6% | 96 Wh | 14 mi |
| 8% | 136 Wh | 9 mi |
10 mph and a 180 lb rider on the throttle. The model caps the motor's draw at what the "48V 32A Controller" can feed, 48 V × 32 A = 1,536 W. Holding 10 mph up 10% or steeper asks more than that, so those grades are left out: on them the GT54 climbs more slowly.
To cost a hilly ride, take its level miles and add the climbing. For a 180 lb rider on the throttle, twenty level miles at 15.5 mph draw about 421.7 Wh from the GT54's pack; 1,000 feet of 8% climbing puts about 287.6 on top, for about 709.2 Wh of the 1,296. Headwinds, stops and restarts add to that, since every mile in the model is ridden at one even pace.
Does rider weight affect range?
A heavier load costs a little on the flat and more on a climb. Added weight adds to the tires' work and the grade's, but not to the air's, so the gap widens as the road tilts up.
| You plus your load | 15.5 mph flat, throttle | 20 mph flat, throttle | 8% climb, 10 mph |
|---|---|---|---|
| 100 lb | 72 mi | 51 mi | 15 mi |
| 130 lb | 67 mi | 49 mi | 13 mi |
| 180 lb | 61 mi | 46 mi | 9 mi |
| 220 lb | 57 mi | 44 mi | 8 mi |
The first column is the rider plus everything carried; the model adds the GT54's own 106.5 lb to each row, since the motor hauls the bike as well, and every figure is on the throttle. The 220 lb row is Riding'times' max load, a limit its FAQ applies to "Rider weight", "Passenger weight (if applicable)" and "Cargo and accessories" together.
Going from 180 lb to the full 220 lb trims the level 15.5 mph ride from 61 miles to 57. At that full load, the GT54 still climbs an 8% grade at 10 mph on the throttle for about 8 miles per charge, without asking more than the controller's 1,536 W.
Does cold weather drain the battery?
Yes, and each drop in temperature costs more. For a 180 lb rider at 15.5 mph on the throttle across level pavement, 61 miles at 77 °F becomes about 48 at 32 °F, 22% less, inside the 10% to 30% cold-weather loss Riding'times' FAQ describes.
| Air | Pack energy vs 77 °F | 15.5 mph flat, throttle |
|---|---|---|
| 95 °F | 99% | 65 mi |
| 77 °F | 100% | 61 mi |
| 68 °F | 98% | 58 mi |
| 50 °F | 93% | 52 mi |
| 41 °F | 91% | 49 mi |
| 32 °F | 89% (80–93) | 48 mi (43–50) |
| 14 °F | 82% (40–83) | 43 mi (21–43) |
Level pavement and a 180 lb rider. The middle figures come from McMaster University's measurements of an LG HG2 cell, recomputed for a 0.5C discharge: the laboratory ran it at 77, 50, 32 and 14 °F, the rows between are interpolated, and the model assumes the cells sit at the air's temperature.
In brackets, the range other published cell data would give. The low figure is the smallest capacity a Samsung data sheet prints at that temperature for a discharge of one to four times the cell's capacity per hour (the 25R and 30Q at 32 °F, the 35E at 14 °F); the high figure is the most energy Casado and colleagues recorded in 2025 at a gentler rate.
Below freezing, three losses stack. The cells give back about 89% of their 77 °F energy, and the air is about 9% denser, by the gas law in the U.S. Standard Atmosphere. The third is cold rubber: the model raises rolling resistance 0.5% for each °F below 77 °F, between Rothhämel's fit for a bicycle tire and Bicycle Rolling Resistance's road-tire average, and holds its 41 °F value below 41 °F.
Riding'times has no objection to riding in the cold; storing a pack in it is another matter, since "prolonged exposure to freezing temperatures may cause permanent battery damage". At 15 lb by the maker's own figure, the pack is easy to take indoors between winter rides.
Do knobby tires cut range? Tires and riding position
On the flat, the tires matter more to range than how you sit. The drum behind the model tests bicycle tires and has no reading for a 60/100-12 motorcycle tire, so the model uses the heaviest-rolling knobby casings Bicycle Rolling Resistance has measured, a coefficient of 0.0126, bracketed by Tengattini and Bigazzi's field average for 138 riders on knobby tires.
| Rolling resistance | 15.5 mph flat, throttle | 20 mph flat, throttle |
|---|---|---|
| 0.0092 · the knobby field average, 138 riders | 71 mi | 51 mi |
| 0.0126 · the heaviest knobby casings on the drum (used) | 61 mi | 46 mi |
| 0.0131 · the field average plus one standard deviation | 60 mi | 45 mi |
Miles from a full pack, 180 lb rider, level pavement. The drum's heaviest-rolling knobby casings, the ones the middle row uses, are Kenda's Juggernaut Pro (0.01262 on the site) and Schwalbe's Hans Dampf at extra-low pressure.
Sand, loose dirt and wet grass have no drum figure at all, so when you ride off the pavement, count every mile as dearer than these rows.
Posture counts for more as the speed rises. The model uses a drag area of 0.640 m², which Tengattini and Bigazzi measured on 37 upright cruiser riders; their 0.603 m² for 90 mountain-bike riders would stretch the 20 mph ride from 46 miles to 48.
Riding'times' 62 and 60 miles, matched to a real ride
Riding'times' 62 miles matches a steady ride on level pavement at about 15.4 mph on the throttle for a 180 lb rider, and its 60 miles about 15.9 mph. The product page adds that "Actual range varies with rider weight, speed, terrain, temperature and riding conditions."
- 62 miles leaves 20.9 Wh a mile: about 15.4 mph on the throttle for a 180 lb rider.
- 60 miles leaves 21.6 Wh a mile: about 15.9 mph on the throttle for a 180 lb rider.
Both figures land within half a mile an hour of Limited Mode's 15.5 mph, and the model's own 15.5 mph ride, 61 miles, sits between them. Riding'times' launch post described its figure as "Up to 62 miles (100km) at steady speed on flat roads", which is the kind of ride the model prices.
Plan every ride on three quarters of the figure in its row. Riding'times' FAQ warns against storing a pack run flat, and keeping a quarter back matches the reserve one measured pedelec held. For a 180 lb rider on level pavement at 15.5 mph on the throttle, that leaves 46 of the GT54's 61 miles to plan with.
Keep a quarter of the pack in hand. Budget 223 to 288 Wh of the 1,296 for each 1,000 feet of climbing at 10 mph. For a 180 lb rider on level pavement, the plan comes to 46 miles at 15.5 mph on the throttle, or 34 at 20.
For a 180 lb rider on the throttle, a 20-mile level ride at 15.5 mph plus 1,000 feet of 8% climbing uses about 709 Wh, inside the 972 Wh in three quarters of the GT54's pack. Email support@redtailebikes.com with your distance, climbing, weight with gear and usual speed, and we will work out the ride before you buy.
Buy the GT54 nowHow every figure here is worked out
Every figure in this section starts from the power the GT54's rear wheel must deliver to hold one speed. Martin and colleagues' model, checked against measurements on an open road in 1998, puts that power in a single equation for a constant speed in still air:
Power at the wheel = v × [ m × g × (Crr × cos θ + sin θ) + ½ × ρ × CdA × v² ]
In it, v is speed; m is the mass of rider, cargo and GT54 together; g is gravity; θ is the slope's angle; Crr is the tires' rolling resistance (0.0126 means a drag equal to 1.26% of the weight on the tires); ρ is the air's density; and CdA, the drag area, measures how much air rider and bike shove aside.
The first term in brackets covers the tires and the grade, the second the air; multiplied by v, the air's term grows with the cube of the speed.
Three steps lie between the wheel and the battery:
- The rear hub motor does all the work, turning with the wheel; with footpegs in place of a crank, the rider adds nothing.
- The motor model borrows a comparable motor's published figures. With no motor maker named by Riding'times, it uses the RM G0H0 geared hub from Bafang's 2021 OEM workbook: n0 510 rpm, nT 426 rpm, 1,000 W rated and an efficiency of "≥ 80" percent. That shape is kept at the GT54's 48 V, with the no-load speed set from Riding'times' own 40 mph, so the comparable's losses carry over unchanged.
- The pack gives up a small share of its energy as internal loss, at the battery efficiency Arango, Lopez and Ceren measured.
Two last lines turn those watts into miles: watt-hours per mile = battery watts ÷ mph, then miles = 1,296 Wh × the share of the pack's energy left at that temperature ÷ watt-hours per mile.
| Input | Value used | Where it comes from |
|---|---|---|
| Bike | 106.5 lb | Riding'times' specification |
| Rider and cargo | 180 lb; the weight table also runs 100, 130 and 220 | 220 lb is Riding'times' max load |
| Battery | 48 V × 27 Ah = 1,296 Wh | Riding'times' specification |
| Motor | one, the RM G0H0's 1,000 W shape at 48 V, no-load speed from the published 40 mph, 80% at the rated point | Bafang OEM workbook 2021; Riding'times' specification |
| Controller cap | 48 V × 32 A = 1,536 W | Riding'times' specification |
| Wheel | 16.72 inches across, the 60/100-12 size code's arithmetic | the size code, checked against Michelin's published StarCross 5 diameters |
| Rolling resistance | 0.0126, the heaviest knobby casings on the drum | Bicycle Rolling Resistance |
| Drag area | 0.640 m², 37 upright cruiser riders | Tengattini and Bigazzi, 2018 |
| Battery losses | 3.2% at 15.5 mph, more at climbing currents | Arango, Lopez and Ceren, 2021 |
| Air | 77 °F at sea-level pressure, 1.184 kg/m³ | U.S. Standard Atmosphere, 1976 |
| Cold | the share of a cell's energy left at each temperature | McMaster University's LG HG2 cell data |
A 15.5 mph ride on the GT54, worked step by step: 180 lb rider, throttle, level pavement. Rolling resistance claims about 112 W and the air about 126 W, 238 W in all at the rear wheel.
At 15.5 mph the 16.72-inch wheel turns 312 rpm. The motor model's constants, 0.570 N·m of torque per amp, a 0.304 Ω winding and a 1.10 A no-load current, are each derived from Bafang's published figures; with them, that load takes 7.3 N·m on 13.9 A, and the motor runs at 75.1% efficiency, short of its 80% because the load is light, drawing 316.5 W.
Add the pack's own losses and the battery must supply 326.8 W, which is 21.08 Wh for each mile at 15.5 mph; 1,296 ÷ 21.08 gives about 61.5 miles, or 46.1 on three quarters of a charge.
Two published benchmarks, recomputed. The road physics and the motor each reproduce the number their source prints:
| Check | Published figure | This model |
|---|---|---|
| Road physics, Martin and colleagues' worked example | 45.7 W for tires and grade, 158.8 W for the air | 45.7 W and 158.8 W |
| The comparable motor at Bafang's rated point | at least 80% efficient | 80% |
The model's self-test reruns Martin and colleagues' Appendix I example, a 90 kg system at 8.36 m/s ground speed on a 0.3% grade, and the RM G0H0's rated point from Bafang's workbook.
Brakes, lights and display
Riding'times specifies "Front and rear disc hydraulic brake + electronic brake" for the GT54, and its page describes a braking system "designed to give riders predictable control across pavement, gravel and recreational dirt riding", under the labels "Hydraulic Brake" and "Electric Brake Assistant".

The front end close up: the orange fork legs above their silver stanchions, the red hydraulic caliper on the disc, and the knobby 60/100-14 tire.
Riding'times' FAQ asks riders to "Regularly inspect your brakes, tires, and lights before riding." Replacement brake parts for Riding'times machines are in our Riding'times parts collection.
The lighting follows motorcycle practice: the GT54 vs GT54 Pro table gives both models an "LED headlight + LED taillight + turn signal light", and the page lists a "Smart Display" with "All Info. At a Glance".
Suspension, tires and water
Riding'times' specification table gives "All-aluminum Barrel Axle Inverted Fork + Rear Suspension", and its geometry block "Front Suspension Travel 8.3 in". The page describes a setup "designed to help manage bumps, uneven pavement, gravel and packed dirt."
The tires are 60/100-14 at the front and 60/100-12 at the rear, and the box list calls the bike "12/14-inch". When a tire wears out, the size code is what you shop by.

From the front, left side: the number plate and its orange graphics, the pack cradle under the seat, and both knobby tires on their orange rims.
Water: rain is fine, a hose on the electrics is not. The FAQ gives every Riding'times model "an IPX5-rated exterior" for "Light rain", "Water splashes" and "Wet roads".
The same FAQ asks riders to "avoid deep water, flooding, or prolonged exposure to heavy rain", and to clean with "A damp cloth", "A soft brush" and "Mild soap and water", keeping water off the controller, the wiring, the display, the motor's electrics, the battery terminals and the charging ports. Standing water and stream crossings are the conditions it tells you to avoid.
106.5 pounds and a 220-pound max load
Riding'times lists 106.5 lb for the GT54, 4 lb more than the GT54 Pro's 102.5, and a 220 lb max load. The FAQ spells out what the load covers, "Rider weight", "Passenger weight (if applicable)" and "Cargo and accessories", and says that "The total combined weight should not exceed the recommended limit."
The 220 lb covers everything aboard; the 106.5 lb bike is not part of it. A 170 lb rider with 25 lb of gear comes to 195 lb, which leaves 25 lb in hand.
The 143 lb in Riding'times' comparison table is a test condition, not a limit: it reads "Load capacity of 143 lb measured at 40 MPH", the load its top-speed figure was taken with. The limit is the specification table's "MAX LOAD 220LBS", and the July 31, 2025 launch post gives a load range of "88–220 lbs (40–100 kg)".

Riding'times' own photograph: a rider in a full-face helmet and riding gear on gravel at dusk, the orange fork legs and rims catching the low sun.
The bike measures 59.76 by 26.38 by 39.76 inches and ships in a carton of 55.91 × 11.02 × 31.50 inches.
Settle where the GT54 will live and how it will travel before you order. At 106.5 lb and nearly five feet long, it belongs in a garage or a ground-floor room, and whatever hitch rack or trailer carries it needs a rating comfortably above its weight.
The Mercer fit test
The Mercers are the seven people every review on this site measures a bike against, so each machine faces the same fit questions (meet the Mercers).
Each verdict rests on a figure Riding'times publishes, such as its two height windows, the seat height, the weight, the max load or its age figures, or on the model's row for that height in the fit tables: how many riders that height put both feet flat at 30.2 inches, and where their knees sit on the pegs.
| Member | Age · Height | Verdict | The number behind it |
|---|---|---|---|
| Frank Kowalski | 63 · 5'10" | Above the product page's window, inside the FAQ's | 5'10" is above 4'2" to 5'9" and inside 140–185 cm; every rider his height in the survey puts both feet flat at 30.2 inches, and 99 of 100 keep a level or lower thigh on the pegs |
| Ruth Kowalski | 61 · 5'5" | Fits | 5'5" is inside both windows; 85 of 100 riders her height put both feet flat at 30.2 inches, and all 100 keep the thigh level or lower on the pegs |
| Jack Mercer | 48 · 6'1" | Above the product page's window, at the FAQ's top | 6'1" is above 5'9" and at the top of 140–185 cm; the median knee his height sits 0.6 inch below level, 85 of 100 keep a level or lower thigh, and the 220 lb max load counts him and his gear |
| Dana Mercer | 45 · 5'7" | Fits | 5'7" is inside both windows; 99 of 100 riders her height put both feet flat at 30.2 inches, and the 220 lb max load covers her and her gear |
| Maya Torres | 32 · 5'6" | Inside the windows; her commute is the question | 5'6" is inside both windows, and 95 of 100 riders her height put both feet flat at 30.2 inches; for a car-free commute, the class section decides where it may go |
| Cole Mercer | 16 · 5'11" | No | Riding'times' FAQ recommends the GT54 from age 10 and its launch post sets a minimum age of 16; with no working pedals and a 2,000 W peak motor it sits outside the federal definition and California's classes, so your state's rules for that kind of vehicle decide who may ride it, and our answer for a 16-year-old is no |
| Ivy Mercer | 12 · — | No | Riding'times' two age figures disagree, 10 in the FAQ and 16 in the launch post; for a machine outside the e-bike definitions, our answer at 12 is no |
The windows and the ages are where the family splits. At 6'1" Jack is past the product page's window yet the pegs still suit him, with the median rider his height sitting 0.6 inch below a level thigh. At 5'5" Ruth is inside both windows, and 85 of 100 bodies her height reach the ground flat-footed from the photographed seat.
Is it UL certified?
Riding'times says its e-bikes are. Its FAQ answers "Are Riding'times eBikes UL Certified?" with "Yes", describing them as "certified to applicable UL safety standards, including UL 2272 and UL 2849, depending on the product."
The same FAQ is clear about what that settles and what it does not: "UL certification relates to product safety standards. UL certification does not determine whether a vehicle is legal to operate in a specific location." For the GT54, that FAQ is where the certification statement appears; the specification table has no UL line.
Has it been recalled?
No. On September 26, 2026 we ran six names, Riding'times, Riding times, Ridingtimes, ridert, Shenzhen Riding Robot and Riding Robot, through the title, product-name and manufacturer fields of the Consumer Product Safety Commission's recall database, then read all 623 records of a corpus built from bicycle, e-bike, battery and scooter terms. Not one names the brand, its company or the GT54.
That empty result counted only because the same search first found recalls known to exist: Ancheer 1, Specialized 54 and Trek 24 in the live fields, and Ancheer 1 and Specialized 49 in the corpus.
The class question: footpegs, 15.5 mph in Limited Mode, 40 mph in gear 3
Settle this before you buy: the GT54 has footpegs rather than working pedals, two speed programs, and a motor figure Riding'times prints above the e-bike lines. Riding'times' FAQ puts the responsibility on the rider: "Riders are responsible for understanding and complying with local laws and regulations."
Under federal law, 15 U.S.C. § 2085(b) describes a low-speed electric bicycle as "a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph."
| The statute's test | The GT54, as Riding'times publishes it |
|---|---|
| Fully operable pedals | none that drive the wheel: the box list names none, the FAQ sets the GT54 models apart from those "equipped with pedals", and the May 27, 2026 post describes "pedals but no chain" |
| A motor of less than 750 watts | "Peak 2000W Rear Hub Motor"; a 48 V 32 A controller |
| Under 20 mph on motor power alone | 15.5 mph in Limited Mode; gear 1's 16 mph; 22 mph in gear 2 and 40 mph in gear 3 in Unlimited Mode |
Sources: § 2085(b); Riding'times' product page, FAQ and its May 27, 2026 post, read September 26, 2026.
The GT54 misses the definition at its first test, before speed or watts come into it: nothing lets your legs drive the rear wheel. Riding'times' own conversion post makes the point about pedals in general: "Decorative or non-functional pedals typically do not satisfy these requirements."
Limited Mode lowers the speed, but the drivetrain and the motor figure stay the same in either program, and your state decides what kind of vehicle the GT54 is on its roads and paths.
Riding'times' FAQ says as much about the pair: "These models are designed with a motorcycle-inspired riding experience and may be subject to different regulations depending on local laws and usage conditions."
California's definition shows how one state draws the line. Its Vehicle Code § 312.5(a), as read on September 26, 2026, defines an electric bicycle as a bicycle "equipped with fully operable pedals and an electric motor that does not exceed 750 watts of power", and its class 3 "ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour."
| Setting | The speed line | Where the GT54 sits |
|---|---|---|
| Limited Mode 15.5 mph, or gear 1 at 16 mph | Under the federal 20 mph and California's 20 mph class 1 and class 2 lines | Under the speed lines; still without working pedals, and with a motor figure above 750 W |
| Gear 2, 22 mph (28 mph in the FAQ) | Past the 20 mph lines; under class 3's 28 mph, or at it by the FAQ | Past the federal and class 2 speed lines as well |
| Gear 3, 40 mph (39 mph in the FAQ) | Past class 3's 28 mph | Past every speed line as well |
Sources: § 312.5(a), § 2085(b) and Riding'times' FAQ, read September 26, 2026.
On registration and the like, Riding'times' FAQ points to your jurisdiction: "Licensing, registration, insurance, and permitted operating areas may vary by jurisdiction." Each state's definition is in our 50-state e-bike law atlas, and our California e-bike law page covers that state in full.
Plan the GT54 around off-road ground: private land and designated routes, under your state's rules for its kind of vehicle. Your state's definition comes first before any road or path.
Where you can ride it
Once you leave the pavement, whoever manages the land decides whether the GT54 is allowed. Two federal land agencies take different routes: the Bureau of Land Management defines an e-bike by its pedals and the same 750 W line, while the Forest Service manages every e-bike as a motor vehicle.
BLM's definition, at 43 CFR 8340.0-5, reads "a two- or three-wheeled cycle with fully operable pedals and an electric motor of not more than 750 watts (1 h.p.)"; any other "motorized vehicle capable of, or designed for, travel on or immediately over land" counts there as an off-road vehicle.
Section 8341.1 opens to off-road vehicles "those areas and trails designated as open to off-road vehicle use", and forbids riding one in violation of state laws and regulations "relating to use, standards, registration, operation, and inspection of off-road vehicles."
In the National Forests, the Forest Service's directives of March 31, 2022 "provide for managing all classes of e-bikes as motor vehicles", in the words of its notice at 87 FR 41278. Once a Ranger District's designations appear on a motor vehicle use map, 36 CFR 261.13 prohibits operating a motor vehicle there "other than in accordance with those designations".
| Where you plan to ride | Who decides | What to read |
|---|---|---|
| Private land, yours or with permission | the owner | the owner's say-so |
| A state or county off-highway vehicle area | that agency | its rules on registration and electric machines |
| A campground | its operator | the campground's own vehicle rules |
| A National Forest road or trail | the Ranger District | its motor vehicle use map (36 CFR 261.13) |
| BLM land | the field office | its route designations (43 CFR 8341.1) |
Every kind of ground has its own manager and its own document, and none of them is on the specification sheet.
Breaking the use rules in subparts 8341 and 8343 on BLM land can bring "a fine of not more than $1,000 or imprisonment for not longer than 12 months, or both", under 43 CFR 8340.0-7. Our public-land e-bike guide walks through each agency's rules in turn.
For anyone planning jumps or races, Riding'times' warranty page has a relevant line: its coverage excludes issues caused by "Improper use, accidents, stunts, racing, or abuse".

- A removable 1,296 Wh pack, 48 V and 27 Ah, which computes to 61 miles for a 180 lb rider at 15.5 mph on the throttle, on level pavement.
- 290 N·m from a 2,000 W peak rear hub motor, driven by a 48 V 32 A controller.
- Two speed programs: Limited Mode holds every gear to 15.5 mph, and Unlimited Mode opens gears of 16, 22 and 40 mph for private land and designated off-road routes.
- An inverted fork and a rear shock, with 8.3 inches of front travel.
- Hydraulic disc brakes at both wheels plus an electronic brake, with LED lights and turn signals.
- A roomy footpeg position: the pegs keep the thigh level or lower for 90 of 100 riders at 6'0", and every surveyed rider from 5'0" to 6'2" reaches the grips sitting upright.
- The lowest price of the four Riding'times dirt bikes we sell: $949 for 290 N·m, against $1,299 to $1,999 for the GT54 Pro, the GT73 and the GT73 Pro.
- A clean recall record: the CPSC database names neither the brand nor the GT54, searched September 26, 2026.
Red flags
These are fit questions: which riders the GT54 does not suit, and the page that serves them.
- Wrong if your rides are on bike lanes and shared paths. It has footpegs, and Riding'times prints a 2,000 W peak motor for it; our e-bike buying guide explains the three classes and matches a pick to each kind of rider.
- Wrong if you want leg power as a backup. Nothing lets your legs drive the wheel; the GT73 and the GT73 Pro ship with pedals in the box.
- Wrong if rider and gear together pass 220 lb. That is Riding'times' max load; the GT73 is rated to 330 lb.
- Wrong if you are under 5'4" and want both feet flat at every stop. From the photographed 30.2-inch seat, 27 of 100 riders at 5'2" reach the ground flat-footed; the foot-down table has your row, or email us your inseam before you order.
- Wrong for anyone under 18, by this page's standard. Riding'times' FAQ says 10 and up and its launch post 16; our 50-state law atlas sets out each state's rules, and our e-bike buying guide matches a legal class to a young rider.
- Wrong if you want more speed or torque. Riding'times prints 3,000 W peak and 338 N·m for the GT54 Pro, in the same size, for $350 more on our store.
- Wrong if one charge has to go further. Its single pack computes to 61 miles at 15.5 mph; the GT73's two packs compute to 83.
- Wrong if it must go up a flight of stairs. At 106.5 lb it needs a garage or a ground-floor room; our reviews hub lists lighter machines with their weights.
Buy it if / Buy something else if
Buy it if you want the least expensive of our four Riding'times dirt bikes, $949 for a compact machine with footpegs, to ride on private land and designated off-road routes, with a Limited Mode that holds 15.5 mph and a computed 61 miles at that speed for a 180 lb rider on the throttle, on level pavement.
It also asks that you and your gear stay at 220 lb or under; that you stand about 5'4" or taller if you want both feet flat at the photographed seat, or that you are happy with one foot down; and that you read your state's rules before the first ride.
For $949 you get a 2,000 W peak hub motor with 290 N·m, a removable 48 V 27 Ah pack, an inverted fork and a rear shock, hydraulic discs with an electronic brake, and LED lights with turn signals. Spread over a year with Shop Pay, our listing's sample plan comes to $85.66 a month at 15% APR, $1,027.92 in total, subject to an eligibility check by Affirm's lending partners.*
Buy something else if you need an e-bike for paths and bike lanes, where our e-bike buying guide matches a class to the ride; if you want the same size with more power, where the GT54 Pro review takes it up; or if you want pedals, more range or a higher load, where the GT73 review and the GT73 Pro review pick up.
For one of the 750 W Riding'times bikes we sell, the GT33 review and the Z8 Pro review take over.
To compare the GT54 with other machines of its kind, our electric dirt bike guide and our hub-drive e-bike guide line them up, and our Riding'times brand page shows the whole range.
Before you buy: the checklist
Work through these ten before the $949 order goes in; if any of the first three fails, the GT54 is the wrong machine for you, whatever the other seven say.
- Confirm where it may be ridden: ask the land manager about any trail, campground or off-road area, and read your state's definition for roads and paths.
- Read Riding'times' two age figures, 10 and up in the FAQ and 16 in its launch post, beside your state's rules for a machine of this power.
- Add up the rider and everything they carry and keep it at 220 lb or under; the 106.5 lb bike does not count toward it.
- Measure your inseam against the foot-down table: from the photographed 30.2-inch seat, 66 of 100 riders at 5'4" and 95 of 100 at 5'6" reach the ground flat-footed.
- Measure the back of your knee; the knee table sets it against the GT54's 18.6-inch drop from seat to pegs.
- Look up your usual ride in the range tables, take three quarters of it, and add the climbing.
- Choose a charging spot that is dry and indoors, and switch off the pack and the bike before you plug in.
- Take the pack indoors in winter, and store it between 40% and 60%.
- Recheck the axle and handlebar bolts after the first few rides (the setup notes).
- Go through the class section before Unlimited Mode goes on anywhere.

Buy yours from our US storeFrequently asked questions
How fast does the GT54 go?
Riding'times prints "40 MPH" in its specification table and headline strip, and its comparison table says that speed was measured with a 143 lb load; the page title and its FAQ give 39 mph. The product page's gears run to 16, 22 and 40 mph, and with Limited Mode on, every gear stops at 15.5 mph (the motor section).
What is the range on the GT54?
Riding'times publishes 62 miles in its headline strip and 60 on a badge lower on the page. Computed for a 180 lb rider on level pavement, a full charge covers about 61 miles at 15.5 mph on the throttle, 46 at 20 mph and 40 at 22; the range tables add hills, load, cold and tires.
Is the GT54 street legal?
Not under the federal e-bike definition: 15 U.S.C. § 2085(b) begins with "fully operable pedals", which the GT54 lacks, and its motor figure is 2,000 W peak. Your state decides what vehicle it is on public roads and what riding it there takes; the class section sets out the lines.
What class is the GT54?
None of the three e-bike classes. California's Vehicle Code § 312.5(a) builds every class on a bicycle "equipped with fully operable pedals and an electric motor that does not exceed 750 watts of power", and the GT54 has footpegs and a 2,000 W peak motor. Plan on private land and designated off-road routes.
Does the GT54 have pedals?
Not working ones. Its box list on Riding'times' product page names no pedals, the bike rides on footpegs, and the FAQ sets the GT54 models apart from those "equipped with pedals"; a May 27, 2026 Riding'times post describes the GT54 as coming "with pedals but no chain". Either way, only the motor drives the rear wheel.
Can I add a pedal kit to the GT54?
Riding'times' May 27, 2026 post on pedal conversions says a working conversion needs "a complete bicycle drivetrain, not just a chain", and concludes that "For most motorcycle-style electric bikes, a full pedal conversion is not practical." If you want pedals from the start, the GT73 ships with them.
How much does the GT54 weigh?
106.5 lb, as Riding'times lists it, 4 lb more than the GT54 Pro's 102.5. The bike is 59.76 × 26.38 × 39.76 inches, and the carton it arrives in is 55.91 × 11.02 × 31.50.
What is the weight limit on the GT54?
220 lb max load, from Riding'times' specification table. Its FAQ counts the rider, a passenger where the bike takes one, and cargo and accessories inside that figure. The 143 lb in its comparison table is only the load its top speed was measured with.
What is the seat height of the GT54?
The geometry block on Riding'times' product page gives 27.2 inches. On its side-profile photograph, scaled by the 41.7-inch wheelbase, the seat's lowest point, where you sit, stands at 30.2 inches; the foot-down table gives your chances at both.
What is the recommended height for the GT54?
4'2" to 5'9" in the geometry block on the product page, and 140 to 185 cm in Riding'times' FAQ. On the US Army's survey bodies, a 5'8" rider with the median 32.6-inch inseam clears the photographed 30.2-inch seat by about 2.5 inches, and from 5'9" up every surveyed rider puts both feet flat (the fit section).
How many watts is the GT54, and how much torque does it make?
Riding'times lists a "Peak 2000W Rear Hub Motor" with 290 N·m of torque, fed by a "48V 32A Controller". For the GT54 Pro beside it, Riding'times lists a 3,000 W peak motor and 338 N·m.
Is the GT54 a hub motor, and does it have a chain?
A hub motor, and no chain. The FAQ on Riding'times' product page says "The GT54 uses a rear hub motor that delivers electric power directly to the rear wheel", so there is no drivetrain between the motor and the tire.
What battery does the GT54 use, and how long does it take to charge?
One removable 48 V 27 Ah pack, 1,296 Wh, which Riding'times rounds to 1300Wh. Its one charger delivers 3 A at 54.6 V, so refilling an empty pack takes no less than about 9 hours; switch the pack off and power the bike down before plugging in, as Riding'times' FAQ asks.
Can the GT54 go in water?
Not deep water. Riding'times' FAQ gives every model "an IPX5-rated exterior" for light rain, splashes and wet roads, and asks riders to "avoid deep water, flooding, or prolonged exposure to heavy rain". Keep water off the controller, the display, the battery terminals and the charging ports.
What size are the GT54's wheels?
A 60/100-14 tire at the front and a 60/100-12 at the rear, per Riding'times' specification table; its box list calls the bike "12/14-inch". Shop for replacement tires by those size codes.
Is the GT54 good for kids?
Riding'times' FAQ recommends it from age 10 and its launch post sets a minimum of 16. With no working pedals and a 2,000 W peak motor, it sits outside the e-bike definitions, so on this page a rider under 18 is a no (the Mercer fit test); our e-bike buying guide matches a legal class to a young rider.
Is the GT54 good for adults?
The maker's windows top out at 5'9" and 6'1". On the survey's adult bodies, every rider from 5'9" up puts both feet flat at 30.2 inches, and 90 of 100 riders at 6'0" keep the thigh level or lower on the pegs. The 220 lb max load is the firmer limit for an adult, because it counts the rider and all gear (the fit section).
What is the difference between the GT54 and the GT54 Pro?
The Pro moves from the GT54's 48 V 27 Ah pack to 60 V 25 Ah, from 2,000 W peak to 3,000 W, from 290 N·m to 338 N·m, and from gears of 16, 22 and 40 mph to 16, 28 and 50, at 102.5 lb to the GT54's 106.5. Our store sells the GT54 for $949 and the Pro for $1,299 (the comparison).
Is the GT54 worth it?
For $949 it brings a 2,000 W peak motor, 290 N·m, a removable 1,296 Wh pack and a computed 61 miles at 15.5 mph, the lowest price of the four Riding'times dirt bikes on our store. It fits riders who have private land or designated off-road routes to use; the verdict names the riders better served elsewhere in our range.
How much does the GT54 cost, and can I pay over time?
$949 on our store on September 26, 2026, with $1,999 shown as the regular price and free delivery in the contiguous United States. Shop Pay showed a sample plan of $85.66 a month for 12 months at 15% APR, $1,027.92 in total, subject to an eligibility check by Affirm's lending partners.*
Limitations of this review
Twenty-one things this review cannot settle, listed so you can weigh them.
- We sell this bike. Give the red flags the same weight as the green.
- This is a specification-verified review. Its figures come from Riding'times' published documents, statutes, our own store record, the published research the range and fit sections cite, or arithmetic on this page.
- Each range figure is for a steady ride: one speed on one grade with no wind and no stops. Stops, starts and headwinds cost more; a tailwind costs less.
- Bafang's figures stand in for Riding'times' motor. Riding'times names no motor maker and, in the pages read, prints a peak rating for this motor and no continuous one; the model uses Bafang's published figures for a 1,000 W geared hub, kept at the GT54's 48 V with its no-load speed set from the published 40 mph. At 82% efficiency in place of Bafang's 80% floor, the 15.5 mph throttle figure moves from 61 miles to 65; on Bafang's 750 W version it is 59, and the 8% climb 8 miles in place of 9.
- No ride of this model to an empty battery checks the model. We found none that states the rider's weight, the speed and a ride to empty together. The physics reproduces Martin and colleagues' worked example and the motor reproduces Bafang's 80% at the rated point; no measured hub-motor map was available to check the motor model at light loads.
- The 25% held back in the planning column is a measured pedelec's, from researchers at KIT, since Riding'times publishes no reserve or usable-capacity figure.
- The tire coefficient is the heaviest knobby casing on a bicycle drum, a stand-in for the 60/100 motorcycle tires, and the tire table brackets it with a field average for knobby tires.
- The cold figures rest on one cell's laboratory data. Riding'times names the pack's 21700 cell format and not its maker, so the central line uses McMaster University's measured LG HG2 cell, bracketed by other published cell data, with the cells taken to be at air temperature.
- The wheel is the size code's, 16.72 inches for 60/100-12, since Michelin lists no 60/100-12; the arithmetic lands within 0.4 mm of every metric diameter Michelin publishes for its StarCross 5 range. On Riding'times' side profile, scaled by the published wheelbase, the rear tire measures 19.3 inches across and the front 19.1; the model's range does not change on that wheel, because its no-load speed is set from the published 40 mph.
- Gear 3 is not priced. The model's comparable motor holds about 28.6 mph on the flat with a 180 lb rider, below gear 3's 40 mph, so the speed tables stop at 28 mph.
- The model caps the motor's draw at the controller's printed 48 V × 32 A, 1,536 W, which leaves out throttle climbs at 10 mph on 10% grades and steeper. Riding'times prints a 2,000 W peak for the motor; if the controller allows more current in short bursts, those climbs could be held for a while.
- Its documents print two top speeds and two sets of gear speeds: 40 mph in the specification table, the headline strip and the comparison table, and 39 mph in the page title and the FAQ; gears of 16, 22 and 40 mph on the product page, 15, 22 and 40 in the comparison on the GT54 Pro's page, and 15.5, 28 and 39 in the FAQ.
- Its documents print two range figures on the product page, 62 miles in the headline strip and 60 on a badge, and "About 60 miles" in its August 5, 2025 post; the range section maps both page figures to a ride.
- Its documents print two weights and two ages: 106.5 lb in the specification table and "About 105lbs" in the July 31, 2025 launch post; "Recommended Age: 10 years and above" in the FAQ and "Minimum Age: 16 years" in the launch post. This review uses the specification table and states both ages.
- Its documents describe the pedals two ways. The box list names none and the FAQ sets the GT54 apart from the models "equipped with pedals", while the May 27, 2026 post says it "comes with pedals but no chain"; either reading leaves nothing for the legs to drive.
- The seat height is the seat's lowest point on Riding'times' photograph, 30.2 inches, where the geometry block prints 27.2; the foot-down table prints both, and the knee figures use the photograph's seat and footpeg. Seat foam that compresses under you shortens the drop to the pegs.
- The footpeg's underside is placed, not measured. At the photograph's 13.3 pixels an inch, the peg's lower edge merges with the black frame behind it, so the model sets it 0.77 inch below the measured top, the height of the same GT54 and GT54 Pro peg on Riding'times' larger GT54 Pro render; the knee figures use the measured top.
- The fit figures use the US Army's ANSUR II bodies: 6,068 soldiers aged 17 to 58, measured from 2010 to 2012, who are not the US public and hold too few bodies under 5'0" for a row, so your own inseam and back-of-knee height decide your row. A boot's sole adds its thickness to the knee figure.
- The grips are read from Riding'times' photograph as it was taken. The handlebar faces the camera there, so the near grip is placed by its round end cap and the stretch of grip visible behind it, on the same frame that gives the seat and the footpeg.
- The hand figure is a ceiling with a relaxed back. On a real ride your back and arms carry part of the load, and standing on the pegs moves it to your legs.
- UL certification rests on Riding'times' FAQ; the GT54's specification table has no UL line, and the pages read link no certificate. The charging time is arithmetic, since the pages read print none for this model. Stock and price were read on September 26, 2026, and both can change, as can local trail and road access.
The bottom line
For $949, the GT54 puts a 2,000 W peak rear hub motor with 290 N·m and a removable 48 V pack of 1,296 Wh into a 106.5 lb mini dirt bike with footpegs, an inverted fork and a rear shock, hydraulic discs with an electronic brake, and LED lights with turn signals.
On level pavement a 180 lb rider gets about 61 miles at 15.5 mph on the throttle, and each 1,000 feet of climbing takes 223 to 288 Wh at 10 mph, up grades of 4 to 8%.
It suits riders with private land or designated off-road routes and a load of 220 lb or under; from about 5'4", most riders put both feet flat at the photographed seat. With Shop Pay on our listing, that is $85.66 a month for 12 months at 15% APR, $1,027.92 in total, subject to an eligibility check.*
Before you pay, settle the class: nothing lets your legs drive the GT54, its motor figure is above the 750 W e-bike line, and Riding'times rates gear 3 at 40 mph. Tell us where you plan to ride before you order, and we will answer with the rule that covers it.

Image credit: every image of the GT54 on this page is Riding'times' own. The cover at the top of this page and the card inside it are Riding'times' photograph of the GT54 on loose gravel with its rider; the machine and rider are the photograph's own pixels.
The sky, bluffs and gravel beyond that photograph's edges are a scene we made around it with Playcut (playcut.ai) to fit the cover, darkened behind the type, which is set in real fonts. The dusk photograph, the studio views, the close-ups and the geometry drawing are Riding'times' product images.
