Tesway C5 AWD in Black on a lit studio floor against a dark wall, side view, under the headline Longtail. 450 lb payload. and a badge reading 112 miles at 16 mph, 450 lb aboard, throttle, both motors, level

Longtail cargo frame · a hub motor in each wheel, 2,000 W rated together, 3,600 W peak, 200 N·m · one 52 V 60 Ah pack, 3,120 Wh · 450 lb payload · 132 lb · 180 to 200 miles in Tesway's figures · ships at 16 mph, 38 mph published · $2,199 · verified September 27, 2026

Quick Answer — Tesway's C5 AWD is a longtail cargo bike with a hub motor in each wheel, a 3,120 Wh pack and a 450 lb payload, for $2,199. At its delivered 16 mph on level pavement, throttle only with both motors, a charge computes to about 152 miles for a 180 lb rider and 112 with 450 lb aboard.

Hold 20 mph instead and that level, throttle-only ride for 180 lb falls to about 119 miles; easy pedaling at 16 mph lifts it to 209. Tesway's specification gives 200 miles on pedal assist and 180 on the motors alone, and the range tables turn your own ride into miles.

Settle two things before you order: carrying anyone, where Tesway's page and manual point two ways, and the class, where its 2,000 W rating and published 38 mph pass the federal and California lines of 750 W and 20 mph (the class section).

On September 27, 2026 our store had both colorways orderable at $2,199, with $3,099 shown as the regular price: Black on this button, or Sage. We ship it free anywhere in the contiguous United States, and Tesway's X5/X7/C5 AWD Value Pack, listed by Tesway at $168.94, is included with your order.

How we verified this Tesway C5 AWD review

Every figure here was read on September 27, 2026, from Tesway's C5 AWD page, its product record, the C5 AWD manual, the dimension drawing on that page, our listing and the statutes quoted in the class section. Range and fit are calculated, and each formula names the inputs it uses.

That makes the review specification-verified: a number traces to Tesway, a statute, our store or arithmetic shown on this page, and the range model reproduces its published benchmarks before it computes anything. We sell the C5 AWD, so read the red flags as closely as the green.

A longtail cargo bike on Tesway's two-motor drive

Tesway's US listing calls it the "TESWAY C5 AWD Cargo Ebike" and, beneath the name, a "Dual-Motor Longtail Cargo Electric Bike for Family Adventures". In practice that means two hub motors, one per wheel, under a low-step frame whose railed rack runs from behind the saddle to past the rear axle.

Black, from the front: the headlight low on the fork, the low-step frame, the battery standing behind the seat post and the railed rack over the rear wheel.

On Tesway's side photograph, scaled by the 55-inch wheelbase, the top edge of the frame dips to 15.9 inches above the floor ahead of the crank, where the drawing prints a 16-inch "Standing height". The deck sits 28 inches up, the whole bike spans 78 inches, and Tesway rates what it carries at 450 lb.

From school runs and grocery hauls to weekend family adventures, the C5 AWD combines dual-motor power, long range, and serious cargo capacity in one versatile longtail e-bike.

Tesway's own summary of the bike, on its C5 AWD page, quoted as written.

From the rear left: the dual-leg kickstand down, the rear hub motor inside the Kenda, the chain and derailleur, and "C5" on the rack's rail.

Under the cargo frame is the drive Tesway fits to its X5 AWD and X7 AWD: the C5's page prints the same "52V 2000W | Peak 52V 3600W", the same 200 N·m and the same 52 V 60 Ah pack. Against the step-through X5 it adds 13 lb of bike and 50 lb of payload, a dual-leg kickstand and turn signals, and it keeps its suspension at the front.

Does the C5 AWD fit you? Saddle, step-over and reach

Tesway's 33 to 40-inch seat range puts the saddle at the fit formula's height for 96 or more of every 100 riders from 5'2" to 5'8", 81 at 5'10", 36 at 6'0" and 9 at 6'2"; Tesway's recommended window runs from 5'3" to 6'5".

The 16-inch standing height is the lowest of the five Tesways we sell, and the post's 40-inch top reaches the formula height for taller riders than any of the other four do (our brand profile's fit table). Every figure below places each of the 6,068 bodies in the US Army's 2012 anthropometric survey on the C5's geometry, saddle at 109% of inseam.

Three steps find your row:

  1. Take your inseam with no shoes on. With your back to a wall, press a hardcover book up between your legs where a saddle would sit, then measure from the floor to the book's spine.
  2. Look up your height below and check that your inseam sits inside that row's range; beyond a 34.6-inch inseam the post has no more height to give.
  3. Settle the last half inch at home with the knee and heel checks in the setup answer.

Tesway's drawing gives eight figures that bear on fit and on carrying.

What the drawing gives Tesway's figure
Recommended heights 5'3" to 6'5"
Seat height 33 to 40 in
"Standing height" 16 in
Handlebar height 47 in
Reach 18 in
Wheelbase 55 in
"Shelf height" 28 in
Load capacity 450 lb

Tesway's C5 AWD dimension drawing: recommended heights 5'3" to 6'5", 450 lb load capacity, 132 lb weight, and a side view marked with total length, handlebar height, wheelbase, minimum and maximum seat heights, chainstay length, standing height, reach, wheel diameter and shelf height

Tesway's C5 AWD drawing. Held against its side photograph at the 55-inch wheelbase scale, three of Tesway's lengths agree within 3.5 percent (the controls table below): the overall length, the standing height and the 565 mm tire in the C5 manual.

Will the seat post reach my saddle height?

Yes for nearly everyone from 5'2" to 5'8", and for about four riders in five at 5'10"; at 6'0" about a third get there, and at 6'4" none do at 109%. The formula puts the top of the saddle 109% of inseam above the pedal axle (Peveler et al., 2005), with 106% the low end of the range Ferrer-Roca and colleagues accept.

Turning that into a height off the floor needs three figures Tesway does not list, each read from its side photograph: a crank axle 10.8 inches up, a 7.0-inch crank, and a seat post leaning back at 73.3° from horizontal.

Your height Typical inseam Saddle height, median rider At 109% At 106%
5'0" 27.1–29.7 in 33.6 in 67 of 100 38 of 100
5'2" 28.0–31.1 in 34.7 in 96 of 100 78 of 100
5'4" 29.1–32.2 in 35.7 in 100 of 100 98 of 100
5'6" 30.2–33.5 in 36.9 in 99 of 100 100 of 100
5'8" 31.1–34.3 in 37.9 in 97 of 100 100 of 100
5'10" 32.2–35.5 in 39.1 in 81 of 100 97 of 100
6'0" 33.2–36.7 in 40.3 in 36 of 100 76 of 100
6'2" 34.3–37.5 in 41.5 in 9 of 100 33 of 100
6'4" 36.3–39.1 in 43.2 in 0 of 100 3 of 100

Floor-to-saddle height for the median rider at each height, and how many of 100 have both settings inside Tesway's 33 to 40 inches; Army survey bodies, men and women pooled. Where a rider's formula height is above the post, the median gap is about 0.9 inches at 6'0", 1.7 at 6'2" and 3.2 at 6'4".

Fully raised, the post suits a 34.6-inch inseam at 109% and a 35.6-inch one at 106%. A longer leg leaves the saddle at its stop and the knee more bent at the bottom of each stroke than the formula would set it; at 5'10", the riders past the stop sit a median of about 0.5 inches low.

The floor of the range matters too. Fully lowered, the 33-inch seat equals 109% of a 27.9-inch inseam, and at 5'0", 33 of 100 riders in the survey have shorter legs than that, so hold your own inseam against 27.9 inches if you stand near the bottom of Tesway's window.

Can I stand over the frame at a stop?

Easily: 95 of every 100 riders at each height in the table clear the 16-inch "Standing height" by 11.1 inches or more, and the lowest top edge measures 15.9 inches on Tesway's photograph. That dip ahead of the crank is where your leg crosses, and the low step is what lets you get on and off with a loaded deck behind you.

Your height Typical inseam Clearance at 16.0 in At 15.9 in
5'0" 28.4 in 11.1 in 11.2 in
5'2" 29.5 in 12.0 in 12.2 in
5'4" 30.5 in 13.1 in 13.2 in
5'6" 31.7 in 14.2 in 14.4 in
5'8" 32.6 in 15.1 in 15.3 in
5'10" 33.8 in 16.2 in 16.4 in
6'0" 34.9 in 17.2 in 17.3 in
6'2" 36.0 in 18.3 in 18.5 in
6'4" 37.6 in 20.3 in 20.4 in

Barefoot inseam less Tesway's 16-inch figure, and less the 15.9 inches measured at the frame's lowest top edge. Each cell is the clearance at least 95 of every 100 riders of that height reach.

Do the bars feel cramped or far away?

Close and high: the grips sit 11.3 to 15.0 inches ahead of the crank axle and 33.5 to 35.2 inches above it, so the median rider leans just 1 to 6 degrees from upright. In Priego Quesada and colleagues' 2017 comparison, twenty recreational cyclists judged the most upright of three trunk positions the most comfortable.

The lean at each height is the smallest trunk angle that lets a straight arm meet the grip from the sit bones, built from the torso and arm lengths of each survey body. Tesway calls the bar an "Adjustable BMX-Style Handlebar", so rolling it moves the grips; the table takes them where Tesway's photograph shows them.

Your height Lean from upright, median rider Across saddle and grip positions
5'0" 1° 0–11°
5'2" 1° 0–11°
5'4" 2° 0–12°
5'6" 3° 0–12°
5'8" 4° 0–13°
5'10" 5° 0–14°
6'0" 6° 0–14°
6'2" 5° 0–14°
6'4" 3° 0–12°

Lean from vertical for the median rider seated mid-saddle, and in the last column the span from sitting forward to sitting back across the measured grip bracket.

How much weight goes through my hands?

Between 5 and 9 percent of your body weight at most with your back relaxed; the table turns that into pounds on each hand. Ten road racers on the brake hoods in Carahalios's 2015 laboratory study put 15% of body weight on the bars, above the C5's relaxed-back share at every height here.

Slane and colleagues measured 36 riders and found pressure over the ulnar nerve, at the heel of the hand, highest in the most stretched hand position; padded gloves brought palm pressure down 10 to 28%. At 1 to 6 degrees of lean for the median rider, the C5's grips keep you well away from that stretch.

Your height Share of your weight, back relaxed Median rider's weight On each hand
5'0" 5% (5–12%) 126 lb about 3 lb
5'2" 6% (5–12%) 139 lb about 4 lb
5'4" 6% (5–13%) 147 lb about 5 lb
5'6" 7% (5–13%) 166 lb about 6 lb
5'8" 8% (5–14%) 179 lb about 7 lb
5'10" 9% (5–14%) 192 lb about 8 lb
6'0" 9% (5–15%) 204 lb about 9 lb
6'2" 9% (5–14%) 216 lb about 9 lb
6'4" 7% (5–14%) 220 lb about 7 lb

Worked from each body's segment weights (Clauser et al., 1969) with the back relaxed, so each figure is an upper bound; the weights are the survey median at each height, and the bracket runs across saddle and grip positions.

What's the fastest way to set the saddle?

Aim for a knee that still bends 25 to 35 degrees when the pedal is at its lowest (Peveler et al., 2007). The C5 manual's assembly steps warn against raising the post "beyond the minimum insertion mark", and its safety list asks you to "Check that the seat is adjusted properly", leaving the height itself to you.

For a quick start, put your heel on the pedal at the bottom of its stroke and raise the saddle until that leg just straightens. Peveler and colleagues found the heel method landed 70% of 19 cyclists in the target range, more than either inseam formula they compared.

The fit arithmetic, step by step

Three rules drive this section: the saddle at 1.09 × inseam above the pedal axle, the lean as the smallest trunk angle at which a straight arm meets the grip, and the hand load as the upper body's weight times that lean over the reach.

For a 5'8" rider on the median 32.6-inch inseam, the formula calls for 35.6 inches from the pedal, which is 28.6 inches above the crank axle once the 7.0-inch crank comes off, and 37.9 inches from the floor, inside the post's 40.

LeMond's rule sits just above it on this frame. Its 88.3% of inseam from the crank axle comes to 28.8 inches, or 110.0% of inseam from the pedal with the crank added back, inside the 109.2 ± 0.9% Peveler and colleagues report.

With no crank length, crank height, seatpost angle or grip position among Tesway's figures, the model takes all four from Tesway's side photograph of the Black C5, scaled by the drawing's 55-inch wheelbase, once that photograph has been held against Tesway's own lengths:

Dimension Tesway lists Measured on its photograph (white studio background) Gap
tire (wheel) diameter 24.0 in 22.8 in −5.1%
tire diameter (the C5 manual's 565 mm) 22.2 in 22.8 in +2.4%
total length 78.0 in 78.6 in +0.7%
standover (drawing 'Standing height') 16.0 in 15.9 in −0.8%
handlebar height, grip-center mean 47.0 in 45.2 in −3.9%
handlebar height, top of the cockpit 47.0 in 48.2 in +2.6%
chainstay (rear axle to crank spindle) 23.6 in 27.7 in +17.2%

The manual's 565 mm tire, the overall length and the standing height agree with the photograph within 3.5 percent. The model's scale comes from the wheelbase and its cockpit from the grips on the photograph, so the drawing's 24-inch wheel diameter, its 47-inch handlebar height and its chainstay line are not used (Limitations explains why).

Two hub motors and the Operate key

Tesway's specification table rates the motors "52V 2000W | Peak 52V 3600W" with 200 N·m, and the detail block restates them as "Rated Power 52V 2000W | Peak Power 52V 3600W". The rated figure is the load the pair is built to carry without a break; the peak is a short burst, and it is the rating that the class section turns on.

Tesway gives the C5's figures for the pair, and the range model divides them as 1,000 W and 100 N·m per hub, the split Tesway's X5 AWD page states for the same drive: "Dual 1000W motors combine for 3600W peak power". Limitations item 7 reruns the key rows at 2,000 W a hub.

The C5 manual's own specification table prints other figures, "Motor Power 250W" and "Max Speed 15.5Mph", and the class section sets both documents side by side; the range tables use the product page's.

The front hub motor at the center of its spokes, beside the disc rotor and caliper, in Tesway's own close-up.

One key chooses one motor or both. "Press the Operate key to switch between Single and Dual Drive modes," says the C5 manual. Up a 6% grade at 12 to 16 mph, running both hubs saves 17 to 19% of the pack's draw per mile against one, while on the flat the two settings stay within 4% (the drive-mode table).

A hub motor turns with its wheel and never through the chain, so the seven gears set how fast your legs spin while the hubs keep road speed, as our e-bike motor guide explains for hub drives. What you take from the pack then depends on your own effort, which the effort table prices.

The half-twist throttle moves the bike with no pedaling at all. Hold the minus key and the manual's cruise control holds your speed "in the pure electric mode", until braking, pedaling or the throttle releases it.

Pedal assist steps from 0, for none, to 5. Walk assist rolls the bike at 6 km/h while you walk beside it, and the manual reserves it "only for use when pushing the electric bike".

One pack for two motors: 3,120 Wh

Fifty-two volts times sixty amp-hours makes 3,120 watt-hours, the "3120WH" in the manual's table, for both motors. Tesway's detail block weighs the pack at 29.8 lb, so lifting it out leaves about 102 lb of the bike's 132.

A key locks the pack in. To free it, the manual has you insert the key, hold it down and turn it counterclockwise, with the warning that "the battery is quite heavy". Get the second key copied in the first week: with both lost, the manual says the pack cannot come out, and a replacement lock cylinder was $25.99 in our Tesway parts collection on September 26, 2026.

Keep charging between 32 and 104 °F, the band the manual sets for riding, storing and charging, and plug in once the gauge reads "less than 20 percent", as it advises. An overnight charge is allowed ("Leaving it connected for overnight charging is OK"), and a pack left unused wants a full charge every month.

The 58.8 V 8 A charger in the box refills an empty pack in 6 hours by the manual's count and in "About 7 hours" by the product page's. At the charger's rated 470.4 W, a 20-to-100% refill takes about 5.3 hours and an empty pack about 6.6, before charging losses.

Tesway's C5 FAQ answers whether to drain the pack first with "No, you should not", adding that its "batteries have built-in mechanisms that protect them from overcharging." The manual counts on "600 charging and discharging cycles" in normal use, and on September 26, 2026 our Tesway parts collection listed a second 52 V 60 Ah pack at $799 and the 58.8 V 8 A charger at $169.

How far the C5 AWD goes, empty and loaded

Level pavement, both motors, throttle only: a full pack carries a 180 lb rider about 152 miles at 16 mph and about 119 at 20, and the full 450 lb payload about 112 miles at 16 mph. Easy pedaling at 16 mph stretches the 180 lb figure to 209 miles, and a steady 8% climb at 10 mph on the throttle brings it down to about 30.

Your own number takes three steps:

  1. Look up the speed you ride and the effort you add in the first two tables, and note the miles.
  2. Budget each 1,000 feet of climbing at 10 mph on 4 to 10% grades: 179 to 223 Wh on the throttle, or 162 to 206 with easy pedaling (the hills table).
  3. Correct for your load and the air temperature, then plan on spending 80% of the pack.

Each table is one steady ride built from Tesway's figures, a comparable hub motor's published data, drum measurements of ten fat tires and a cycling-power model checked on an open road. The formula subsection prints the equation and walks one ride through it.

How many miles at each speed, and what does pedaling add?

Speed moves range more than anything else you choose: throttle only, a charge runs 213 miles at 10 mph and 119 at 20. From 16 to 20 mph the figure drops from 152 miles to 119, since the power the air takes climbs with the cube of speed, and (20 ÷ 16)³ gives 20 mph about 1.95 times the air power of 16.

Speed, flat Per mile Full charge With 20% kept
10 mph 14.7 Wh 213 mi 170 mi
12 mph 16.3 Wh 192 mi 153 mi
15 mph 19.3 Wh 162 mi 129 mi
16 mph 20.5 Wh 152 mi 122 mi
18 mph 23.1 Wh 135 mi 108 mi
20 mph 26.1 Wh 119 mi 96 mi
25 mph 35.1 Wh 89 mi 71 mi
28 mph 41.7 Wh 75 mi 60 mi
32 mph 51.8 Wh 60 mi 48 mi

Every row: a 180 lb rider on the throttle alone with both hubs driving, over level pavement in 77 °F air. The C5 leaves the box set to 16 mph, so the rows above it need a setting beyond the default, which the class section addresses; the right-hand column leaves in the pack the fifth the manual says to charge at.

A little pedaling goes a long way: 75 W from your legs turns the 16 mph figure of 152 miles into 209. Easy pedaling here means 75 W and steady pedaling 150 W; with the motors off, those efforts alone would roll a 180 lb rider on this 132 lb bike at about 8.3 and 12.4 mph on the flat, a fair test of which column you could hold.

Speed, flat Throttle only Easy pedaling (75 W) Steady pedaling (150 W)
16 mph 152 mi 209 mi 326 mi

A 180 lb rider on flat pavement with both motors, from a full pack. At 16 mph, easy pedaling costs the pack 14.9 Wh a mile against 20.5 on the throttle alone. In the 326-mile cell your legs out-work the motors, which leans on the least-checked part of the model, the motors' losses at light load (Limitations item 5).

The assist level sets how much the motors add to your effort and does nothing else in these sums, so choose the row for your speed and the column for your legs. The manual's range advice agrees, beginning with "Frequent changes in speed will consume more energy."

Do the gears or the Operate key change the battery bill?

Change gear for your legs, and pedal to spare the battery. With the motors in the hubs, the pack's draw at a set speed and grade falls only as your own effort rises:

Your ride Throttle only Easy pedaling (75 W) Steady pedaling (150 W)
16 mph, flat 20.5 Wh 14.9 Wh 9.6 Wh
20 mph, flat 26.1 Wh 21.6 Wh 17.2 Wh
12 mph, 4% grade 52.6 Wh 42.7 Wh 33.4 Wh
12 mph, 8% grade 99.2 Wh 86.7 Wh 74.8 Wh

Pack watt-hours per mile with both motors for a 180 lb rider in 77 °F air; easy pedaling is 75 W from the rider and steady pedaling 150 W.

The Operate key is the other lever. One motor and two cost within 4% of each other on level ground; on a climb, two hubs sharing the load each work nearer their efficient point, and the pair draws less:

Your ride Both motors One motor Both motors vs one
12 mph, flat 16.3 Wh 15.9 Wh +3%
12 mph, 6% grade 74.7 Wh 92.7 Wh −19%
16 mph, flat 20.5 Wh 20.5 Wh 0%
16 mph, 6% grade 75.9 Wh 91.6 Wh −17%
20 mph, flat 26.1 Wh 26.7 Wh −2%
20 mph, 6% grade 80.3 Wh past one motor's rating —
25 mph, flat 35.1 Wh 36.7 Wh −4%
25 mph, 6% grade 89.5 Wh past one motor's rating —

Watt-hours drawn from the pack per mile on the throttle, 180 lb aboard. "Past one motor's rating" marks a ride that one motor could hold only above its rated output in the model, which treats the two hubs as equal (Limitations item 9).

On the flat, then, the key barely changes the bill, and in hilly country both motors are the cheaper choice. Use the seven gears for a comfortable cadence and the lowest ones for starts and climbs, most of all with a loaded deck.

What does each hill cost the battery?

A great deal: at 10 mph on the throttle, each 1,000 feet of climbing on 4 to 10% grades takes 179 to 223 Wh beyond the same distance on the flat, or 162 to 206 with easy pedaling. Raising you and the bike accounts for 53 to 66% of the throttle figure and the motors and pack lose the rest, and the manual warns that "Rough road conditions and hilly terrain will consume more energy."

A 180 lb rider on the 132 lb C5 makes 312 lb to raise, and lifting that 1,000 feet takes 118 Wh at the wheel. Up 8% at 10 mph on the throttle the pack pays 208 Wh per 1,000 feet, so all 3,120 Wh would carry you up about 15,000 feet with none left for the flat; the model earns nothing back on descents, which keeps a hill budget cautious.

Grade Wh a mile Miles, throttle Miles, easy pedaling Top steady speed
2% 32 Wh 97 mi 146 mi 32.5 mph
4% 52 Wh 59 mi 78 mi 31.1 mph
6% 76 Wh 41 mi 51 mi 28.2 mph
8% 102 Wh 30 mi 36 mi 25.5 mph
10% 132 Wh 24 mi 27 mi 23.1 mph
12% 165 Wh 19 mi 22 mi 20.9 mph
15% 220 Wh 14 mi 16 mi 18.2 mph

At 10 mph with 180 lb aboard and both motors; throttle only in every column but the fourth, where you add 75 W of easy pedaling. The last column is the fastest steady speed the pair holds on the throttle at its rated output on each grade, above the 16 mph default in every row.

Planning a day with climbs? Price the hills on top of the flat miles. Twenty level miles at 16 mph on the throttle, about 410 Wh, plus 1,000 feet of climbing at 8%, about 208 Wh, comes to about 618 Wh of the 3,120 in the pack. Wind and stops come on top, because the model rides every mile at one steady pace.

How far does a full 450 lb load go?

On the flat, weight costs a little; on a climb it costs a great deal. Extra pounds add to the tires' and the grade's share of the work but nothing to the air's, so light and heavy riders drift further apart as the road tilts up, and the manual says so in one line: "Carrying more weight on the E-bike will consume more energy."

You plus your load 16 mph flat, throttle 20 mph flat, throttle 8% climb, 10 mph
130 lb 162 mi 126 mi 38 mi
180 lb 152 mi 119 mi 30 mi
230 lb 143 mi 114 mi 25 mi
280 lb 135 mi 108 mi 21 mi
450 lb 112 mi 93 mi 13 mi

The rider plus everything carried; the model adds the bike's own 132 lb to every row. Throttle only, both motors. The bottom row is the full 450 lb Tesway rates the C5 AWD to carry.

Filling the payload costs about a quarter of the level range and more than half of the climbing range. Going from 180 lb to 450 lb aboard takes the 16 mph ride from 152 miles to 112 and the 8% climb at 10 mph from 30 miles to 13, because on a grade every added pound has to be lifted too (the hills section).

How much range does winter take?

More with every degree below room temperature. Worth 152 miles at 77 °F, the 16 mph throttle ride comes to about 121 miles at 32 °F, the coldest air Tesway allows for riding and charging.

Air Pack energy vs 77 °F 16 mph flat, throttle Inside Tesway's 32–104 °F range
95 °F 99% 158 mi yes
77 °F 100% 152 mi yes
68 °F 98% 145 mi yes
50 °F 93% 131 mi yes
41 °F 91% 125 mi yes
32 °F 89% (80–93) 121 mi (109–127) yes
14 °F 82% (40–83) 110 mi (53–110) no: below it

Both motors, level ground, 180 lb aboard. The central figure in each row rests on McMaster University's measured LG HG2 cell, recomputed at a 0.5C discharge from the lab's 77, 50, 32 and 14 °F runs, with the rows between interpolated and the cells assumed to sit at air temperature.

The bracket spans the published cell data. Its low end is the least capacity a Samsung data sheet gives at that temperature for a discharge of one to four times capacity per hour (25R and 30Q at 32 °F, 35E at 14 °F), and its high end the most energy Casado and colleagues recorded in 2025 at a gentler rate.

At freezing, three losses stack. The cells give back about 89% of their 77 °F energy, 80 to 93% across sources, and 32 °F air is about 9% denser under the gas law in the U.S. Standard Atmosphere.

The tires stiffen as well: the model raises rolling resistance 0.5% for each °F under 77 °F (0.9% per °C), a rate between Rothhämel's fit for a 42 mm tire and Bicycle Rolling Resistance's average for road tires, and holds the 41 °F value below that.

The 14 °F row sits under Tesway's floor, and the manual is plain about charging outside the band: "Never charge the battery when ambient temperatures are outside this range." It also says to "Avoid parking your E-bike outside when there is rain or snow", so in winter the C5 is a garage bike between rides.

Does tire choice or riding posture change the range?

On level ground, the tire matters more to range than your posture does. Ten 26 × 4.00 fat tires ran on Bicycle Rolling Resistance's drum at 12 psi, 18 mph and a 94 lb load, and drew between 23.2 and 42.1 W.

With no drum figure for the C5's 20 × 4.0 Kenda, the model uses the median of the ten, a coefficient of 0.0105, and brackets it with the lowest and with Kenda's Juggernaut Pro.

Rolling resistance 16 mph flat, throttle 20 mph flat, throttle
0.0070 · the lowest of ten fat tires on the drum 176 mi 134 mi
0.0105 · the median of ten fat tires (used) 152 mi 119 mi
0.0126 · a Kenda Juggernaut Pro, the heaviest-rolling Kenda fat tire on the drum 141 mi 112 mi

Miles from a full charge, both hubs on, 180 lb aboard, level ground. On its own test page, Kenda's Juggernaut Pro reads 0.01262.

For pressure, the manual says to "Refer to the tire’s sidewall for the pressure range", and the drum figures above were taken at 12 psi. Among its range tips, the manual counts correct pressure and "keeping the E-bike clean and well lubricated" as savings.

No drum measures sand, gravel or grass; send us the route and we will model your surface. Posture weighs more as speed climbs: Tengattini and Bigazzi measured a drag area of 0.640 m² across 37 upright cruiser riders, the figure used here, and 0.603 m² across 90 everyday mountain-bike riders, which would lift the 20 mph throttle ride from 119 miles to 124.

Tesway's 180 and 200 miles, as steady rides

Both of Tesway's range claims line up with a steady ride the model can name. Tesway's specification lists 200 miles on pedal assist and 180 as "Pure Electric Range", and its FAQ adds that "Actual range may vary depending on rider weight, cargo load, terrain, speed, weather, and assist level."

Tesway's figure Throttle only Easy pedaling (75 W) Steady pedaling (150 W)
Pedal assist, 200 miles about 11.3 mph about 16.5 mph about 19.2 mph
Pure electric, 180 miles about 13.2 mph about 17.6 mph about 20.1 mph

The steady speed on level ground at which a 180 lb rider on both motors would use all 3,120 Wh over Tesway's distance: 200 miles leaves 15.6 Wh a mile, and 180 miles 17.3.

Read that way, Tesway's 200 miles fits easy pedaling near 16.5 mph and its 180 the throttle near 13.2 mph. The model's 16 mph rides fall on either side: 152 miles on the throttle below both, and 209 with easy pedaling above them.

Plan on 80% of the row that matches your ride. The manual recommends charging "when the power is less than 20 percent", and planning on the rest leaves that reserve in the pack: at 16 mph on the throttle, 122 of the full 152 miles.

Choose your row, hold back a fifth of the pack, then add the hills. Climbing at 10 mph adds 179 to 223 Wh per 1,000 feet on the throttle, less when you pedal. For 180 lb on level pavement, plan on 122 miles at 16 mph on the throttle and 96 at 20.

A day of errands, 20 flat miles at 16 mph plus 1,000 feet of 8% climbing uses about 618 Wh on the throttle, a quarter of the 2,496 Wh in 80% of the pack. Email us your distance, climbing, total load and usual speed, and we will run the ride before you order. Black is $2,199, as is Sage.

The formula behind every range figure

Holding a steady speed takes a steady flow of power at the rear wheel, and the model Martin and colleagues validated on an open road in 1998 gives it in one line for constant speed in still air:

P = v × [ m × g × (Crr × cos θ + sin θ) + ½ × ρ × CdA × v² ]

In it, P is the power at the rear wheel, v the road speed, m the mass of rider, load and bike together, g gravity, θ the slope's angle, Crr the tires' rolling resistance (0.0105 is a drag of 1.05% of the weight on the tires), ρ the air's density and CdA the rider's drag area, a measure of the air pushed aside.

The first bracketed term is the tires and the slope; the second is the air, and once multiplied by v, the air's share grows with the cube of speed. Four stages lie between that wheel and the pack:

  1. Your pedaling reaches the rear wheel through the chain at 97.7% efficiency, the chain figure Martin and colleagues measured, and the motors make up the difference.
  2. Two hub motors share the motors' part evenly in Dual mode, and one carries all of it in Single mode.
  3. Each hub is modeled on a comparable motor with published figures: Bafang's 2021 OEM workbook gives its RM G0H0 hub a no-load speed of 510 rpm (n0) and a rated speed of 426 rpm (nT), 1,000 W at 48 V, and "≥ 80" percent efficiency. On Tesway's 52 V and the manual's 565 mm tire, Bafang's unloaded speed works out to 36.6 mph; the model pins it at Tesway's published 38 and takes 80% at the rated point, with efficiency falling at lighter loads.
  4. The pack gives up a small share of its energy as internal loss, at the efficiency Arango, Lopez and Ceren measured on a 48 V pack.

From those, watt-hours per mile = battery watts ÷ mph, and miles = 3,120 Wh × the share of pack energy available at that temperature ÷ watt-hours per mile.

One ride, worked end to end: a 180 lb rider holding 16 mph on the throttle with both motors, on level pavement. At the wheels that ride needs 243.3 W: 104.6 W against rolling resistance and 138.6 W against the air.

At 16 mph the 565 mm wheels turn 242 times a minute. The motor model gives each hub 0.865 N·m of torque per amp, a 0.356 Ω winding and a 1.02 A no-load current, all derived from Bafang's published figures. Holding this ride, each hub turns out 4.8 N·m on 6.6 A at 76% efficiency, below its rated 80% at so light a load, and together they pull 318.5 W.

Adding the pack's own losses, the battery supplies 328.1 W, which at 16 mph is 20.51 Wh a mile: 3,120 ÷ 20.51 is about 152.1 miles, or 121.7 with 20% held in reserve.

Three published benchmarks, reproduced. Each piece of the model returns the figure its own source prints, or the gap is shown:

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%
Bafang's no-load speed at Tesway's 52 V on the 565 mm tire Tesway's 38 mph top speed 36.6 mph

The model's self-test reproduces Appendix I of Martin and colleagues (8.36 m/s, a 90 kg system, a 0.3% grade) and the RM G0H0's rated point in Bafang's workbook; its 510 rpm at 48 V, scaled to 52 V on the C5's tire, lands 1.4 mph under Tesway's 38, and pinning the model at 36.6 instead moves the 20 mph ride by one mile (Limitations item 6).

No measured day on the C5 AWD itself was found to set beside the model. YouTube searches under six Tesway model names (265 results), Reddit's archive and the owner reviews on Tesway's page were read on September 26, 2026, and Tesway's C5 page showed no reviews.

The nearest recorded rides are on the X5/X7 AWD, which share the C5's pair of motors and pack on a lighter frame, and our X7 AWD review sets them beside its own model.

Carrying cargo and people

Tesway rates the C5 AWD at 450 lb, the same figure on every document that prints one: the highlights strip ("450LBS Max Load"), the specification table, the detail block ("Max. Payload Capacity -450 LBS"), the drawing and the manual ("Max load 450 lb"). Count it as you plus everything aboard, the cautious reading, and keep each tire inside the load and pressure its sidewall prints.

The rack is the cargo deck: 28 inches up on Tesway's drawing, railed along both sides, with the pack at its front edge. Tesway's page sells the whole load as "Built to Carry. Ready to Go Further." and its FAQ describes "a longtail rear cargo area that can be configured for passengers or cargo".

Tesway's C5 accessories, with the prices our store listed on September 26, 2026, each naming the C5 in the compatibility line Tesway wrote for it:

Add-on What Tesway says Our price
Large Rear Rack Basket "spacious rear basket, perfect for groceries, gear, and everyday essentials" $89.99
Foldable Rear Platform "Carry oversized cargo with ease" $79.99
Front Basket "perfect for groceries, gear, and everyday essentials" $69.99
Front Cargo Rack "secure support for baskets, cargo, and daily essentials" $49
Cargo Trailer "Maximum load: 100 kg (220 lbs)" $299

Tesway's words are from each accessory's own listing, read on September 26 and 27, 2026. Tesway's trailer listing names the C5 AWD among the bikes it fits; email us before ordering the trailer and we will confirm the hitch for your C5.

Passengers: two Tesway documents, two answers

On carrying people, Tesway's page and its manual point different ways, so both are printed here. The page describes a bike "for Family Adventures" with "room for kids, cargo, and everyday essentials", and says the frame "supports up to 450 lbs, giving you the capacity for passengers, cargo, and everything in between."

Tesway also makes three passenger parts for the C5 alone: a Child Safety Rail with Backrest to "Keep young passengers secure and comfortable on every ride", an Extended Passenger Seat that "mounts securely on the rear rack", and Running Boards for "secure foot support for rear passengers". Our parts collection lists them at $129, $89 and $189.

The C5 manual reads differently. Its care section says the bike "is designed for regular country road use for a single person", its safety instructions include "Prohibit children to use it for safety", and it adds that laws "mandating the use of helmets and the use of infant seats, will automatically apply to E-bikes."

Before anyone rides behind you, get two answers in writing: the most the rack carries with a passenger on it, and the youngest passenger Tesway's rail and seat are made for. Email support@redtailebikes.com and we will put both questions to Tesway and send you its written reply; tell us your state as well, and we will add its rule on carrying a passenger.

Brakes, lights, signals and the NFC display

Tesway lists four-piston hydraulic brakes front and rear on 203 mm × 2.3 mm rotors, and pairs them with "fat tires, and stable handling" to "give you confident control—even with passengers or a full load." The manual's pre-ride list includes the pads: "Check brake pads and ensure the brake pad material isn’t thinner than the backing plate it attaches to."

With a heavy deck, check them often. Pads for the C5 AWD were $20.99 a pair and $39.99 for two pairs in our Tesway parts collection on September 26, 2026, and the manual asks you to check "the effectiveness of the brakes before each use."

"Integrated Turn Signals" is how Tesway puts it, to "Signal your next move clearly for greater visibility on the road": in the manual, the left and right turn keys flash the matching rear signal, and a second press turns it off. The detail block lists "Front & Rear Light & Turn signal".

The color display with an NFC card held to it; swiping the card near the display switches it on.

The color LCD gives "Clear ride data with NFC access and convenient USB charging". To start the C5, the manual has you turn the battery key to on, then hold the on/off key and enter the code the manual prints, or swipe one of the two NFC cards from the box. A replacement card was $25.99 in our Tesway parts collection on September 26, 2026.

Suspension, tires, gears and weather

Tesway's highlights list the suspension as "Suspension Front Fork": a "120mm Lockout Suspension Fork" in the table, which its feature text says "Smooths out bumps and rough roads for a more comfortable ride". The rear, which carries the deck, is a rigid frame.

The front fork with Tesway's own 120 mm marking, the blue lockout knob on top and the Kenda below.

The tires are 20 × 4.0 Kendas with "reflective sidewalls for added visibility", the frame carries an "IPX6 Water-Resistant Design" rated by Tesway to "handle rain splashes and unpredictable weather", and the drivetrain pairs a Shimano 7-speed derailleur with a 52T chainring and a chain tensioner for "improved chain stability on every ride".

On September 26, 2026, our Tesway parts collection listed a C5 AWD chain at $25.99, a C5 AWD seat post at $59 and a C5 AWD handlebar at $159, and a 20 × 4.0 inner tube at $25.99; the C5 AWD version of the 20 × 4.0 tire was sold out that day.

132 pounds to park and to lift

At 132 lb on Tesway's page and drawing, about 102 lb with the 29.8 lb pack lifted out, the C5 is a bike for a garage, a ground-floor room or a shed. It runs 78 inches long and 47 inches to the handlebar on the drawing, and the frame does not fold.

The dual-leg kickstand is built for exactly the moment a cargo bike needs it; in Tesway's words it gives "Extra stability for easier loading, unloading, and steady parking". Put it down before you load the deck, and lift a heavy load off before you tip the bike off the stand.

Measure the parking spot before the delivery. At 132 lb and 78 inches, the C5 AWD wants a ground-level space; a car rack must be rated for all 132 lb with room to spare, and even with the pack out it is a two-person lift at about 102 lb.

The Mercer fit test

The Mercers, the same seven people, stand beside every bike we review, so each machine answers the same fit questions (meet the Mercers). Each verdict reads a figure Tesway publishes (the height window, seat range, standing height and payload), the manual's lines on children and passengers, or the fit tables built from them.

Member Age · Height Verdict The number behind it
Frank Kowalski 63 · 5'10" Fits; the saddle is worth checking At 5'10" the post reaches the formula height for 81 of 100 riders at 109% and 97 at 106%, and the frame's lowest edge sits 15.9 inches up
Ruth Kowalski 61 · 5'5" Fits At 5'5" the post reaches the formula height for 100 of 100 riders, and she clears the 16-inch standing height by 13.7 inches
Jack Mercer 48 · 6'1" Inside the window, with the saddle often short of the formula 6'1" sits inside 5'3"–6'5", and the post reaches the formula height for 20 of 100 riders his height at 109% and 50 at 106%
Dana Mercer 45 · 5'7" Fits; carrying her family waits for Tesway's written answer At 5'7" the post reaches the formula height for 99 of 100 riders; the manual's "single person" line and the page's "room for kids" are both printed above
Maya Torres 32 · 5'6" Fits At 5'6" the post reaches the formula height for 99 of 100 riders
Cole Mercer 16 · 5'11" Set by his state The manual's "Prohibit children to use it for safety" sets no minimum age, and his state's rule for a machine rated above 750 W decides whether a 16-year-old may ride it; at 5'11" the post reaches the formula height for 63 of 100 riders
Ivy Mercer 12 · — No, as a rider; as a passenger, not before Tesway answers in writing "Prohibit children to use it for safety" rules her out as a rider; whether she rides on the deck waits on the passenger answer

For this household the C5 fits every adult rider, and the open question is the deck, not the saddle. The standover table clears Tesway's 16 inches by a wide margin at every height, and only Jack, at 6'1", finds the post short of the formula more often than not.

Has it been recalled?

No. On September 27, 2026 we searched the Consumer Product Safety Commission's recall data in its title, product-name and manufacturer fields for Tesway, TESWAY, teswaybike and Tesgo (the parent Tesway's European About page names), and read every field of a 623-record corpus of bicycle, e-bike, battery and scooter recalls.

None names Tesway or its parent, and no record in the corpus carries the model code C5.

The search proved it could see recalls first: the same queries returned 1 for Ancheer, 54 for Specialized and 24 for Trek.

Class and road rules: two documents, one 750 W line

Settle this before you order. Tesway's US page publishes a default speed, a top speed and a motor rating for the C5 AWD, its manual's table publishes another rating and speed, and the e-bike definitions test more than one of those figures.

Under 15 U.S.C. § 2085(b), a federal low-speed electric bicycle has "fully operable pedals", a motor "of less than 750 watts (1 h.p.)", and a motor-only top speed "less than 20 mph" with a 170-pound rider aboard.

What the definition asks The C5 AWD, in Tesway's own figures
Fully operable pedals "Left & Right Pedals" in the box
A motor under 750 watts "Rated Power 52V 2000W", "Peak Power 52V 3600W" on the US page; "Motor Power 250W" in the manual's table
Under 20 mph on motor power 16 mph as delivered and 38 mph published on the US page; "Max Speed 15.5Mph" in the manual's table

§ 2085(b) read September 26, 2026, and Tesway's C5 AWD page September 27; the manual's table from the C5 manual.

Tesway's two documents give the C5 two different motor ratings, and the class answer turns on which one describes the bike you receive. The US page, its record and its highlights put the pair at 2,000 W rated with a 3,600 W peak and a 38 mph top speed; the manual's specification table prints 250 W and 15.5 mph.

Ask us before you order, and we will get Tesway's written statement of the C5's rated power.

California draws its line in the same place. Read on September 26, 2026, California Vehicle Code § 312.5(a) builds its definition on "an electric motor that does not exceed 750 watts of power" and cuts class 3 assistance off at 28 miles per hour.

A speed setting moves a bike across a speed line and leaves its motor rating where it was. The C5 manual treats full power the same way, saying riders "should check against local laws to ensure full power mode is permitted", and its introduction adds that "The laws may differ slightly depending on the county or city you live in."

Setting The speed line Where the C5 AWD lands
As delivered, 16 mph Below the federal 20 mph and California's class 2 throttle line Under the speed lines; on the US page's rating, the motors stay above 750 W
At the 38 mph Tesway publishes Class 3 assist ends at 28 mph and a class 2 throttle at 20 Beyond the speed lines as well

Sources: § 312.5(a), § 2085(b) and the C5 manual, read September 26, 2026.

How your state treats the C5 on its roads and paths, and what riding it there requires, is your state's decision. Each state's definition is in our 50-state e-bike law atlas; for California, our California e-bike law page goes further.

Get the motor rating in writing first, then plan around your state's rule for it. On the US page's 2,000 W the C5 sits outside the 750 W classes whatever its speed setting; tell us where you will ride it and we will answer before you order.

Trails and public land: who decides

Off the road, whoever owns or manages the land decides whether the C5 AWD may go there, and the federal land agencies build their e-bike rules on the same 750 W line.

On Bureau of Land Management ground, 43 CFR 8340.0-5 confines the e-bike definition to a motor "of not more than 750 watts (1 h.p.)", and anything beyond it counts as an off-road vehicle. Under 43 CFR 8341.1, such a vehicle goes only where the field office has designated land "open to off-road vehicle use".

In National Forests, the Forest Service directives of March 31, 2022 handle e-bikes as motor vehicles, "managing all classes of e-bikes as motor vehicles" as the notice at 87 FR 41278 puts it, and where a Ranger District has published a motor vehicle use map, 36 CFR 261.13 bars riding "other than in accordance with those designations".

Where you plan to ride Who decides What to read
Your own land, or land you have permission to use the owner the owner's permission
A state or county off-highway vehicle area that agency its registration and equipment 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 open, limited and closed designations (43 CFR 8341.1)

The land manager's own document settles each row; nothing in Tesway's specification settles any of them.

The penalty rule for BLM land, 43 CFR 8340.0-7, sets "a fine of not more than $1,000" or imprisonment "for not longer than 12 months", or both, for a violation. Agency-by-agency detail is in our public-land e-bike guide, and the C5 manual's list of misuse includes "extreme maneuvers, such as extreme off-road use, jumping, or carrying an excessive load".

Name the trail, forest or field office before you buy. Email support@redtailebikes.com and we will reply with the rule that governs it. Sage is $2,199, and Black is the same price.

Green flags / Red flags

Green flags

  • A 450 lb payload, one figure on Tesway's page, drawing and manual alike, on a railed 28-inch deck.
  • Two hub motors with a Single/Dual key; up a 6% grade, the pair draws 17 to 19% less than one motor.
  • A 3,120 Wh pack: about 152 miles at 16 mph on the throttle for a 180 lb rider on the level, and 112 with the full 450 lb aboard.
  • A 16-inch standing height, the lowest of the five Tesways we sell, with a 40-inch post that reaches the formula saddle for 81 of 100 riders at 5'10".
  • Four-piston hydraulic calipers clamping 203 mm rotors front and rear, where a loaded deck needs them.
  • Turn signals and a dual-leg kickstand: signals for traffic, and a stand Tesway built for "easier loading, unloading, and steady parking".
  • An upright cockpit: the median rider leans 1 to 6 degrees, with no more than 5 to 9% of body weight on the hands.
  • Carrying parts made for it: baskets front and rear, a platform, a front rack and a trailer, all naming the C5.

Red flags

Each one is about fit: who the C5 AWD is wrong for, and what to do instead.

  • Wrong if anyone will ride on the deck before Tesway has answered in writing. Its page and manual differ on passengers; email us and we will get the rack limit and passenger age from Tesway for you.
  • Wrong if your inseam is above 34.6 inches and you want full leg extension. The saddle is then at the top of its post; find your row in the saddle table.
  • Wrong if your state's e-bike classes are the rule you must ride under. On the US page's rating the motors are above 750 W; email us and we will match you to a bike that fits your state's classes.
  • Wrong for a home up a flight of stairs. It weighs 132 lb, about 102 lb once the pack is out, which is a job for two people; describe your stairs to us and we will point you to a lighter bike we sell.
  • Wrong if you want rear suspension. The C5 has its travel at the front; the step-through X5 AWD adds a rear coil shock to the same drive, with a 400 lb payload.
  • Wrong if you mostly ride alone with a bag. The X7 PRO carries the same 3,120 Wh on one motor for $1,549.
  • Wrong for trails open to Class 1 only. The throttle and the motor rating each keep it off them; our public-land guide lists who manages what, and we will check your trail.
  • Not a bike for a child to ride. Tesway's manual lists "Prohibit children to use it for safety" among its safety instructions; your state's age rules are in our 50-state law atlas.

Buy it if / Buy something else if

Buy it if you want to haul groceries, gear or a week's shopping on a long railed deck with two driven wheels and a 3,120 Wh pack, computed at 152 miles at 16 mph on the throttle for a 180 lb rider and 112 with the full 450 lb aboard, on private land, gravel, errands and wherever your state lets a machine rated above 750 W ride.

It also asks for an adult rider inside Tesway's 5'3" to 6'5" window, with the saddle at its top past a 34.6-inch inseam, a ground-level spot for a 132 lb, 78-inch bike, and somewhere to charge between 32 and 104 °F.

For $2,199 you get two hub motors rated 2,000 W together, 200 N·m, a removable 3,120 Wh pack, a 450 lb payload, a 120 mm lockout fork, four-piston hydraulic brakes, turn signals, seven Shimano gears and a dual-leg kickstand. Through Shop Pay on our listing, the 12-month plan is $198.48 a month at 15% APR, $2,381.76 in all.

Buy something else if you need a machine inside your state's e-bike classes, which we will match to your state by email; if you want a maker's payload figure that already counts passengers in optional child seats, which the Eunorau FAQ quoted in our Eunorau G30-CARGO review does for its $1,699 longtail; or if you want a 750 W longtail at $1,699, which our Eunorau MAX-CARGO review covers.

For a cargo frame at $899, our Riding'times GT33 review sets out a 750 W rated hub and a 330 lb max load. Our Tesway brand profile sets the C5 AWD beside the other four Tesways we sell, and our e-bike reviews hub indexes every machine we have reviewed.

Before you buy: the checklist

Ten checks before you spend $2,199; the first three decide where the C5 AWD can go and who can ride it.

  1. Get Tesway's rated power in writing through us, since the US page and the manual's table print different figures.
  2. Look up the rule for each place you will ride: your state's e-bike definition covers roads and paths, and the land manager's rule covers trails.
  3. Get the passenger answers in writing before anyone rides on the deck: the rack limit with a passenger, and the youngest passenger Tesway's parts are made for.
  4. Measure your inseam against the fit tables, knowing the post tops out for an inseam of 34.6 inches.
  5. Check your height against Tesway's 5'3" to 6'5" window.
  6. Add up yourself and the load and keep it at or under Tesway's 450 lb payload, with each tire inside its sidewall ratings.
  7. Find the parking and plan the lifting for 132 lb and 78 inches of bike, plus the load on its deck.
  8. Match your ride to a row in the range tables, add the climbing, and keep 20% of the pack back.
  9. Choose where it will charge: somewhere held between 32 and 104 °F, with 6 to 7 hours free for the charger.
  10. Confirm the trailer hitch with us if a trailer is part of the plan, and keep the trailer's load at or under its 220 lb.

Frequently asked questions

How far can the Tesway C5 AWD go on one charge?

Tesway's own figures are 200 miles on pedal assist and 180 on the motors alone. Computed for level pavement on the throttle with both motors, your full pack covers about 152 miles at 16 mph for a 180 lb rider, 119 at 20 mph, and about 112 at 16 mph with the full 450 lb aboard; climbing at 10 mph costs 179 to 223 Wh per 1,000 feet (the range tables).

How fast can the Tesway C5 AWD go?

It arrives set to 16 mph, the page's "Default Speed", and Tesway publishes 38 mph as its top speed; the manual's own table prints "Max Speed 15.5Mph". Anything past the default brings in the class question, and the manual asks you to check local law before you use full power mode.

On the US page's rating, 2,000 W for the pair, the C5 sits past the 750 W line in the federal definition and in California's e-bike classes; its manual's table prints 250 W, so ask us for Tesway's written rating first. Delivered at 16 mph it stays under their speed lines, and your state decides how it is treated on your roads (the class section).

Can the Tesway C5 AWD carry kids or a passenger?

Tesway's documents differ, so settle it before anyone climbs on. The product page describes "room for kids" and Tesway sells a C5 rail, a passenger seat and running boards, while the manual describes a bike for "a single person". Email us and we will get Tesway's written answer, with the rack limit and the youngest passenger its parts are made for (the passenger section).

How much weight can the Tesway C5 AWD carry?

450 lb, the one figure on Tesway's highlights, specification table, detail block, drawing and manual; count yourself, anyone aboard and all your cargo in that total. With the full 450 lb aboard, the model still gives you about 112 miles at 16 mph on the throttle over level pavement, and 13 on an 8% climb at 10 mph (the weight table).

How much does the Tesway C5 AWD weigh?

132 lb on Tesway's page and drawing, of which the pack is 29.8 lb, so about 102 lb with the pack lifted out. Size your car rack or lift for the full 132 lb plus whatever rides on the deck (parking and lifting).

What height rider does the Tesway C5 AWD fit?

Tesway's drawing gives 5'3" to 6'5". Its 33 to 40-inch seat gets 96 or more of every 100 riders from 5'2" to 5'8" to the formula's saddle height, 81 at 5'10" and 36 at 6'0"; if your inseam is over 34.6 inches, your saddle will sit at the top of the post (the fit section).

Tesway C5 AWD or X5 AWD: which should I buy?

Choose by what rides behind you. Both run the same two motors and 3,120 Wh; the C5 adds a railed 28-inch deck, a 450 lb payload, turn signals and a dual-leg kickstand for $2,199, while the X5 AWD is a 119 lb step-through with a rear coil shock and a 400 lb payload at $1,799. Tell us your loads and we will compare the two for you.

Is the Tesway C5 AWD dual motor, and can it run on one?

Yes to both. The manual describes "dual motors at both the front and the rear" and switches "between Single and Dual Drive modes" with the Operate key. On level ground the two modes stay within 4% of each other per mile, and up a 6% grade both motors draw 17 to 19% less (the motors section).

What battery does the C5 AWD use, and how long does it take to charge?

One 52 V 60 Ah pack of 3,120 Wh, charged by the 58.8 V 8 A charger in the box. Tesway gives "About 7 hours" and the manual 6 hours from empty; at the charger's rated 470.4 W, your 20-to-100% refill takes about 5.3 hours and an empty pack about 6.6 (the battery section).

Can the Tesway C5 AWD pull a trailer?

Tesway's Cargo Trailer listing names the C5 AWD among the bikes it fits, with a maximum load of 100 kg (220 lb), and it is $299 in our Tesway accessories. Email us before you order it and we will confirm the hitch for your C5; the trailer's load counts against its own 220 lb, and the range tables above leave a trailer out, so plan on fewer miles when you tow.

What accessories fit the Tesway C5 AWD?

For cargo, Tesway's rear rack basket ($89.99), foldable rear platform ($79.99), front basket ($69.99), front cargo rack ($49) and trailer ($299) all name the C5 in their compatibility lines, at our September 26, 2026 prices. The C5 rail, passenger seat and running boards are passenger parts, so the passenger section comes first for those.

What colors does the Tesway C5 AWD come in?

Black and Sage, both $2,199 and both orderable on our listing and at Tesway on September 27, 2026.

Does the Tesway C5 AWD fold?

No. Tesway's specification lists a non-foldable aluminum frame, and the drawing gives 78 inches of length and 47 inches to the handlebar, so plan on a truck bed, a large van or a rack rated for well over 132 lb.

Can I replace the C5 AWD's battery or other parts?

Yes. The pack comes out with its key, and on September 26, 2026 our Tesway parts collection listed Tesway's 52 V 60 Ah battery at $799, plus a C5 AWD seat post ($59), handlebar ($159) and main cable ($69.99). The manual's error table runs from E02 to E10; send us the code your display shows and we will confirm the part.

What brake pads does the Tesway C5 AWD use?

Pads made for its four-piston hydraulic calipers: C5 AWD brake pads were $20.99 a pair in our Tesway parts collection on September 26, 2026, and the six-piece kit Tesway advertises, which comes with an order placed here, includes brake pads.

What warranty does the Tesway C5 AWD have?

Buy it from us and a fault becomes our job under our policies: send photos and your order number, we open the claim with Tesway and see it to the end, and our listing commits Redtail to coordinating the repair or replacement "at no cost to you". Want Tesway's own terms for your order? Ask us before buying and we will have them confirmed in writing.

Is the Tesway C5 AWD worth it?

At $2,199 on our store on September 27, 2026, against a $3,099 regular price, with free shipping in the contiguous United States, you get two hub motors, 3,120 Wh and a 450 lb payload on a railed longtail deck. It suits adults who haul regularly, fit its 33 to 40-inch seat, and ride where a machine rated over 750 W is allowed (the verdict).

Can I finance the Tesway C5 AWD?

Yes. Shop Pay on our listing came to $198.48 a month for 12 months at 15% APR on September 27, 2026, $2,381.76 in all, with 3- and 6-payment plans at the same rate.

Limitations of this review

Twenty-six points this review cannot settle, listed so you can weigh them.

  1. We sell this bike. Read the red flags with the same care as the green.
  2. This review is specification-verified. Its figures come from Tesway's published documents, statutes, our own store record, the published research the range and fit sections cite, or arithmetic on this page.
  3. Each range figure is one steady ride: one speed, one grade, no wind and no stops. Stops, starts, headwinds and soft ground cost more.
  4. Bafang's figures stand in for Tesway's motors. Tesway gives the pair's rated and peak power and torque, and its documents read here do not say whether the hubs are geared or direct drive. At 82% efficiency instead of Bafang's 80% floor, the 16 mph throttle figure rises from 152 miles to 168.
  5. At light motor load the model has no measured check. Where your legs do most of the work, as in the steady-pedaling column at 16 mph, the answer rests on motor losses we could not check against a published hub-motor map.
  6. The unloaded speed is Tesway's 38 mph. At the comparable motor's own 36.6 mph, the 16 mph throttle ride stays at 152 miles and the 20 mph ride moves from 119 miles to 120.
  7. The rating used is 1,000 W a motor. Read as 2,000 W a motor, the 16 mph throttle ride comes to 137 miles, the 20 mph ride to 111, and the 8% climb to 36.
  8. Tesway's two documents print two ratings: 2,000 W rated and 3,600 W peak for the pair on the US page, and "Motor Power 250W" with "Max Speed 15.5Mph" in the manual's table. The range tables follow the US page, and the rated power is asked of Tesway in writing through us.
  9. The model splits torque evenly between the hubs in Dual mode and treats either hub as the one that drives in Single mode; the documents read here do not describe how the controller shares the work.
  10. No measured range day on the C5 AWD was found. The record of the routes read is in the range model's validation file; the nearest recorded rides are on the X5/X7 AWD, with the same motors and pack on a lighter frame.
  11. Every figure assumes all 3,120 Wh are usable. The documents read here do not say how much of the pack the battery management releases; on one measured pedelec, researchers at KIT found 75% in use during a standard range test.
  12. The tire coefficient is the median of ten 26 × 4.00 fat tires at 12 psi, a larger size than the C5's 20 × 4.0 Kenda, and the tire table brackets it.
  13. The cold figures rest on one cell's laboratory data. The documents read here do not name the C5's cells, so the central line uses McMaster University's measured LG HG2 cell, bracketed by Samsung and other published cell data.
  14. Tesway gives two charge times, "About 7 hours" and 6 hours from empty; the charger's rated 470.4 W refills 20 to 100% in about 5.3 hours and an empty pack in about 6.6 before charging losses, and the page plans on Tesway's longer figure.
  15. Tesway gives two wheel sizes: the drawing's 24-inch "Wheel Diameter" and the manual's 565 mm tire. The model uses 565 mm, and because its unloaded speed is pinned at 38 mph, the range figures come out the same on either.
  16. Two wheelbases are printed, 55 inches on the drawing and 1,414.6 mm (55.7 inches) in the manual; the fit model scales from the drawing's 55.
  17. The documents read here give no rack limit of their own, no passenger weight limit and no passenger age for the C5, which is why the passenger section asks Tesway in writing. Tesway's general FAQ gives 75 kg for an adult on the rear seat of its folding X5X7, a different model, so that figure is not applied to the C5.
  18. The C5 AWD page read here carries no UL statement. Where a building or an insurer asks for certification, email us and we will request Tesway's documents in writing.
  19. Trail access is set locally. The land manager's rule decides, it can change, and neighboring systems differ.
  20. The recall search covers the CPSC's US database under the names listed; a recall filed under another company name would need that name searched.
  21. Colorways and prices were read on September 27, 2026, and both can change, as can Tesway's gift offer, our parts prices and the Shop Pay terms.
  22. The fit figures use the US Army's ANSUR II bodies: 6,068 soldiers aged 17 to 58, measured in 2010 to 2012, who are not the US public, so your own inseam decides your row.
  23. The cockpit is measured on Tesway's photograph. The crank, crank height, seatpost angle and grips are read at the 55-inch wheelbase scale, with three published lengths agreeing within 3.5%; the drawing's 24-inch wheel reads 5.1% large, its 47-inch handlebar height falls between the grips and the top of the cockpit, and its 23.6-inch chainstay line does not match the 27.7 inches from rear axle to crank on the photograph.
  24. The hand figure is a ceiling with a relaxed back. On a real ride your back and arms carry part of the load, and we found no study that measures hand load on a bike set up like this one.
  25. The 109% formula is a starting point. In 19 trained cyclists it put 55 to 65% inside the 25-to-35-degree knee range and the heel check 70%, so the knee range and the heel check should settle the saddle.
  26. Tesway's C5 page showed no owner reviews on September 27, 2026, so no owner is quoted.

The bottom line

At $2,199, the C5 AWD puts two hub motors, 200 N·m and a removable 3,120 Wh pack under a low-step longtail with a railed 28-inch deck, a 450 lb payload, a 120 mm lockout fork, four-piston hydraulic brakes, turn signals and a dual-leg kickstand.

For a 180 lb rider on level pavement with both motors, the model gives about 152 miles at 16 mph on the throttle, or 209 with easy pedaling, and with the full 450 lb aboard still about 112; each 1,000 feet of climbing at 10 mph costs 179 to 223 Wh on the throttle.

The right owner is an adult who hauls often, fits the frame with an inseam under about 34.6 inches for the formula's saddle, keeps the bike at ground level, and rides where a machine rated above 750 W is allowed.

On Shop Pay, the C5 costs $198.48 a month for 12 months at 15% APR.

Before you order, settle two things through us in writing: Tesway's rated power for the C5, which decides its class, and its answer on passengers. Tell us your roads, your trails and your loads, and our reply will name the rule for each.

Both colorways are $2,199: this button buys Black, or choose Sage. Over 12 months on Shop Pay it is $198.48 at 15% APR; we ship free inside the contiguous United States and file the carrier claim ourselves if it arrives damaged.
