Folding trike · 500 W rear-drive motor (1,100 W peak) or 750 W (1,400 W peak) · cadence sensor and half-twist throttle · 48 V 13.5 Ah pack, 648 Wh · ADDSHOX fork with 80 mm of travel · a mechanical disc on every wheel, a differential and a parking brake · 14.1-inch standover · 310 lb payload ("230+80 LBS") · 20 mph · $1,099 or $1,499 on October 11, 2026 · verified October 11, 2026

Quick Answer — Addmotor's Citytan M-315 is a folding trike for riders 5'1" to 5'9": $1,099 with a 500 W motor or $1,499 with a 750 W one, a 14.1-inch step, a differential, a parking brake and 20 × 3.0 tires. Our model gives a 180 lb rider about 56 miles a charge at 12 mph on the throttle on level pavement.

Two questions decide the order before the color does: which motor your streets need (500 W or 750 W), and whether your barefoot inseam stays under about 31.7 inches, the point past which the highest saddle setting falls short of the pedaling formula (fit).

On October 11, 2026 our store listed the 500 W Citytan at $1,099, against a $1,499 regular price, and the 750 W at $1,499. This button opens checkout for Cyan with the 500 W motor, the one 500 W color Addmotor showed in stock that day; the 750 W comes in Cyan, Red and Orange. It ships free to any address in the contiguous United States, and a box damaged in transit is our claim to file, not yours.

How we verified this Addmotor Citytan M-315 review

The record behind each figure is Addmotor's: its Citytan product page with its four tabs, feature copy and product FAQ, the size drawing, the question board and the posts in which Addmotor prints Citytan figures, read on September 28 and October 11, 2026. Our store supplied the price, the colors and the Shop Pay plans, read the same October 11.

Each figure in this specification-verified review comes from Addmotor, a statute, our store or a study cited where it is used, or from arithmetic shown on the page; the range and fit sections set their inputs beside their tables. We sell this trike, so the red flags get as much room as the green ones.

Addmotor's Size & Fit, Technical and Performance tabs as each one shows when clicked, first read September 28, 2026 and read again on October 11, when every value matched. The saddle heights run from the ground to the saddle's top, as the drawing's arrows show. Our price was read the same day.

A folding trike with a choice of two motors

The Citytan is a $1,099 trike that folds: one upright frame and one pack, sold with either of two rear-drive motors, the 750 W for $1,499. Addmotor's June 25, 2026 post puts the arrangement in one sentence: "Currently, both the classic 500W version and the brand-new 750W version are available side by side, offering flexible choices for different riding environments."

A rider in a striped T-shirt and shorts stands astride an orange Addmotor Citytan M-315 at the curb of a residential street, one hand on the bar and one on the saddle, with a stucco bungalow and a broad shade tree behind

An orange Citytan with a rider standing over it, in Addmotor's own photograph, which gives a sense of the trike's size against a person.

You step through a 14.1-inch gap in front of the saddle, pedal a seven-speed drivetrain from a conventional crank, and steer a single front wheel on an 80 mm fork. The motor drives the rear axle through a differential, which Addmotor's feature copy lists beside the parking brake.

Addmotor's product FAQ positions it for "flatter city cruising" with the 500 W and "steep hills and heavier riders" with the 750 W; its post of September 4, 2025 introduced it as "An entry-level folding electric trike designed for budget-conscious riders".

500 W or 750 W: which Citytan?

On level ground the two motors give almost the same range; the $400 buys speed up hills. In our model, a 180 lb rider on the throttle at 12 mph gets about 56 miles from the 500 W and 54 from the 750 W, while up a 10% grade the 500 W holds about 8.2 mph and the 750 W about 11.8.

Prices from our store; torque from Addmotor's posts of April 11 and April 13, 2026 (500 W) and July 20, 2026 (750 W); stock as Addmotor's own buy box showed each option on October 11, 2026; the range and climbing figures from the range model.

Addmotor frames the same choice in its launch post of July 4, 2026: "While the standard 500W version remains optimized for efficiency on flat urban terrain, the new 750W rear-drive system (peaking at 1400W) provides the necessary torque for steep inclines and payload transport."

The 500 W also falls inside more states' e-bike definitions: 36 jurisdictions against the 750 W's 26, on our October 11, 2026 screen of every state's wording (the class section lists them).

Choose the 500 W for flat neighborhoods and errands, a lighter budget, and the wider legal footing. Choose the 750 W for hills over 6% or for riding near the 310 lb payload: at 310 lb on an 8% grade it holds about 10.2 mph where the 500 W holds about 6.9.

Citytan or Citytri E-310: two folding trikes on our shelf

Addmotor's other folding trike with a review on our site, the Citytri E-310, carries a bigger pack and folds lower, for $500 more than the 500 W Citytan. Both pages, the Citytan's and the Citytri's, list a rear-drive motor, a differential, a parking brake, a disc on each wheel and a 20 mph top speed.

Each column is Addmotor's own tab figures for that trike (Citytan, Citytri), read October 11, 2026, with our store's prices from the same day.

For the $500, the Citytri adds 312 Wh of pack, 50 lb more rider allowance and a fold 16.6 inches lower; the Citytan keeps the wider 3.0-inch tires, 55 mm more fork travel and $500 in your pocket. Asked for a bigger battery for longer rides, Addmotor answered on April 22, 2025: "Not for this one. But we have another model with bigger battery like the citytri."

If your car's cargo opening is lower than 45.3 inches or a charge must carry you far past 50 miles, our Citytri E-310 review lays out that trike's figures.

Who the Citytan fits: 5'1" to 5'9" and a 14.1-inch step

Addmotor's window is 5'1" to 5'9", and across it the pedaling formula wants the saddle top 31.8 to 36.1 inches from the pedal for the median rider. Addmotor's saddle heights, 28.7 to 34.6 inches, are measured from the ground, so a leg longer than about 31.7 inches asks the formula for more than the highest setting gives, before the pedal's own height off the ground is counted.

The formula places the saddle 109% of your inseam from the pedal axle at the bottom of the stroke, as Peveler and colleagues compared it in 2005. Addmotor prints the saddle's height off the ground but no bracket height or crank length, so each row below gives the distance to aim for and a tape measure on the trike finishes the job.

Three steps size you:

  1. Measure your inseam barefoot. With your back to a wall, draw a hardcover book up between your legs until it sits as a saddle would, then measure from the floor to its top edge.
  2. Read your row in the saddle table, then check the ceiling table for how often your height runs past the top setting.
  3. On the trike, point one crank down along the seat post and measure from the saddle's top to the middle of that pedal; if the post tops out short of your row, email us before you ride.

How high does my saddle go?

Find your height, then read across to the distance from the saddle's top to the pedal axle. The third column applies the 109% formula to your height's median inseam; the last two run it at 106%, the low end of the range Ferrer-Roca and colleagues report, and at 110.4%, the top of the range they propose.

Your height Typical inseam Saddle top to pedal axle At 106% At 110.4%
5'1" 27.7–30.3 in 31.8 in 31.0 in 32.3 in
5'2" 28.0–31.1 in 32.2 in 31.3 in 32.6 in
5'3" 28.7–31.6 in 32.8 in 31.9 in 33.2 in
5'4" 29.1–32.2 in 33.3 in 32.3 in 33.7 in
5'5" 29.7–32.6 in 33.8 in 32.9 in 34.3 in
5'6" 30.2–33.5 in 34.5 in 33.6 in 34.9 in
5'7" 30.7–33.9 in 35.1 in 34.1 in 35.5 in
5'8" 31.1–34.3 in 35.6 in 34.6 in 36.0 in
5'9" 31.7–34.8 in 36.1 in 35.1 in 36.6 in

Inseams run from the 5th to the 95th percentile at each height among the 6,068 people in the US Army's ANSUR II survey, and the three distances use the median. Your own inseam outranks your row: 1.09 inches of saddle for each inch of leg.

Above a barefoot inseam of 31.74 inches, the highest saddle setting cannot reach the 109% distance; above 32.64 inches, it cannot reach 106%. That follows from Addmotor's 34.6-inch top setting alone, since the pedal sits above the ground even at the bottom of its stroke:

Your height Median inseam Can't reach 109%, of 100 Can't reach 106%, of 100
5'1" 29.2 in 0 0
5'2" 29.5 in 1 0
5'3" 30.1 in 3 0
5'4" 30.5 in 11 1
5'5" 31.0 in 25 5
5'6" 31.7 in 46 17
5'7" 32.2 in 68 29
5'8" 32.6 in 84 50
5'9" 33.1 in 95 71

Counted over the same survey's bodies at each height. Each figure is a floor: the pedal's real height off the ground, which Addmotor does not print, only adds riders to it.

Addmotor prints the same 5'1" to 5'9" window on its tab, its drawing and its posts. Inside that window, a long-legged rider at 5'7" or taller rides with a more bent knee at the top setting than the formula calls for, so check your inseam against the ceiling table above before ordering.

Can I step through it at a stop?

Yes: the frame's low point is 14.1 inches, and every surveyed rider from 5'1" to 5'9" steps over it barefoot. In the 5'1" row, 95 of every 100 riders have 13.6 inches or more to spare.

Your height Typical inseam Clear the 14.1 in standover, of 100
5'1" 29.2 in 100

5'7" 32.2 in 100
5'8" 32.6 in 100
5'9" 33.1 in 100

Each row sets that height's barefoot inseams, from the same survey, against Addmotor's 14.1-inch standover; the middle column gives the median leg.

Addmotor's product FAQ gives the step its own line: "The 14.1-inch ultra-low step-over frame allows effortless mounting."

Will I lean forward to reach the bars?

The lean is not computed here, because Addmotor publishes no grip position measured from the saddle. Its tab prints a 12.6-inch reach and a 44.5-inch handlebar height but no seat angle or bracket height, and the drawing's own arrows do not share a scale (the formula subsection).

The 44.5-inch handlebar height sits 9.9 inches above the 34.6-inch top saddle setting, so at any setting the bar rides above the saddle; set the saddle by your row first, then ride a block and judge the reach.

How much weight goes through my hands?

Not computed either: hand load follows from the lean, and the lean needs the grip's position. For a sense of scale, ten road racers riding on their brake hoods in Carahalios's 2015 laboratory study carried 15% of their weight on the bars, a stretched posture the Citytan's tall bar does not ask for.

Keep your elbows soft and your back upright. Numb or tingling palms point to padded gloves, which cut palm pressure by 10 to 28% across the 36 riders Slane and colleagues measured.

How do I set the saddle at home?

Raise the saddle until your heel, resting on the pedal at the bottom of its stroke, leaves your leg straight. Riding on the ball of your foot then keeps a slight bend; in Peveler and colleagues' 2005 comparison, the heel method placed 70% of 19 trained cyclists inside the 25 to 35 degree bend the cycling literature recommends against injury.

Tighten the seat-post clamp between steps and ride a block before you move it again. If the post reaches its top and your knee still bends with your heel on the pedal, stop there: your leg needs more saddle height than the Citytan offers, and the Citytri reaches higher.

The fit arithmetic, step by step

The saddle table comes from a single rule: from the pedal axle at the bottom of the stroke to the saddle's top, 1.09 times your inseam. Worked for a 5'8" rider at that height's median inseam, 32.64 inches to two decimal places, the rule asks for 35.6 inches, and LeMond's rule, 88.3% of the inseam from the crank axle, gives 28.8 inches for the same leg.

The two rules count from different points, and only a crank length joins them; Addmotor prints none, so each figure stands on its own rule. The ceiling table needs neither: 34.6 divided by 1.09 is 31.74 inches of inseam, and by 1.06 it is 32.64.

Nothing is measured on Addmotor's drawing, because its own seven dimension arrows do not share a scale. Scaled by any one of them, it reproduces at most two of the other six within 3.5%:

Line Wheelbase scale Length scale Top-saddle scale
top saddle (34.6 in) +10.8% +10.2% —
low saddle (28.7 in) +13.1% +12.5% +2.0%
bar height (44.5 in) +5.1% +4.6% −5.1%
standover (14.1 in) −3.3% −3.9% −12.8%
wheelbase (47.2 in) — −0.5% −9.8%
total length (69.3 in) +0.5% — −9.3%
reach (12.6 in) +7.2% +6.6% −3.3%

How far each of Addmotor's arrows, read tip to tip on its drawing and divided by the scale the column names, lands from the figure printed beside it; a dash marks the line that sets the scale. Read this way the arrows imply anywhere from 16.4 to 19.2 pixels per inch, and with no single scale the drawing yields no bracket, crank or grip position.

Two rear-drive motors on one 48 V system

Both motors drive the rear wheels through a differential on a 48 V system, rated at 500 W with a 1,100 W peak or 750 W with a 1,400 W peak. The Technical tab lists both on one line, "500W Rear-Drive Motor (1100W Peak) / 750W Rear-Drive Motor (1400W Peak)", with an "Addmotor 25A Controller" and a "Small Display".

Addmotor's documents give the 500 W two torque figures. Its specification tables of April 11 and April 13, 2026 read "500W Rear-Drive (Peak 1,100W), 65Nm Torque", while the prose of the same posts says "60Nm of torque"; the range model uses 65, and the climbing table notes the one row the lower figure would change.

For the 750 W, Addmotor's post of July 20, 2026 states "The Citytan M-315's 750W rear-drive motor delivers 90 Nm of torque and peaks at 1,400W."

The assist reads your pedaling cadence, and the throttle moves you with your feet at rest. The Performance tab lists a "Cadence Sensor" with "5 Level Pedal Assist" and a "Variable Speed Control - 1/2 Twist Throttle", over a "Shimano 7-Speed" drivetrain and a "KMC Stainless Chain".

Addmotor's color display for the Citytan: a black panel with plus, power and minus buttons beside a screen showing a large speed figure in mph, a pedal-assist level in green inside a blue and orange ring, a battery bar and a trip counter

The color display, in Addmotor's image: speed, assist level, battery and trip data, with the buttons on its left.

The top speed is "20 Mph" on the Technical tab, and the display carries a USB port in Addmotor's feature copy. How your state reads a 500 W or 750 W motor with a 20 mph top speed is set out in the class section.

A 648 Wh pack in an aluminum case behind the seat

The pack holds 648 watt-hours, 48 volts times 13.5 amp-hours, for both motors. The Technical tab lists a "48V*13.5Ah Lithium Battery", and Addmotor's launch post of March 27, 2025 prints "48V 13.5Ah Battery (648Wh)".

It rides behind the seat in a potted aluminum case that slides out. Addmotor's feature copy says "Made of aluminum, the battery pack has excellent heat dissipation. The battery is also protected through potting", and adds that "With its convenient pull-out design, you can effortlessly take it home for storage and charging."

Its post of July 20, 2026 rates the potting material "UL94 V-0", a flammability rating for plastics; if a certificate for the pack itself matters to your building or insurer, email us and we will ask Addmotor for it in writing.

A charge from empty runs about 6.75 hours on the 2 A charger: 13.5 amp-hours at 2 amps, before charging losses. Addmotor's post of September 4, 2025 lists "48V 13.5Ah / 6–8 hrs", and the charger in the box is a "48V*2.0A 5 Pins Short Plug US Standard DC Charger".

There is no larger pack for the Citytan. Addmotor's answer to a rider asking for one, of April 22, 2025, sends longer rides to the Citytri, whose 960 Wh pack is set out in the comparison above.

Three numbers from Addmotor's own posts cover the pack's care:

  • recharge "when it has a 10%-15% charge left", in its battery-health post;
  • "keep your battery charge between 20% and 80% for the best lifespan", in its maintenance guide;
  • charge "at room temperature (between 10 and 25 degrees Celsius)", 50 to 77 °F, in the same guide.

Range: how far a charge takes the Citytan

For a 180 lb rider on level pavement on the throttle, a full pack lasts about 65 miles at 10 mph on the 500 W, 63 on the 750 W, and 29 at the 20 mph top on either; with the full 310 lb aboard, the 12 mph ride runs about 46.

Easy pedaling at 75 W stretches that 12 mph run to about 150 miles on the 500 W, and a 6% grade held at 10 mph on its throttle cuts a charge to about 9 miles.

Your Citytan day comes out of these tables in three steps:

  1. In the first two tables, find the row for your pace and the column for your motor and your pedaling.
  2. Price the climbs: on the 500 W's throttle at 10 mph, each 1,000 feet costs 167 to 189 Wh on a 4 to 6% grade; on the 750 W's, 146 to 194 Wh on 4 to 10% (the hills table).
  3. Adjust that figure for your load and the air temperature, then plan around 85% of the pack.

Each row is one steady ride, built from Addmotor's figures, a comparable motor's published data, field measurements of everyday riders' tires and a cycling-power model validated on an open road; the formula subsection works one ride through and sets the model beside an owner's ride to an empty pack.

How many miles does each speed give, and how much do your legs add?

On the throttle, every step up in speed costs miles, and the two motors land within a few miles of each other. The air pushes back with the square of your speed: on the 500 W, each mile at 20 mph takes 22.2 Wh from the pack, against 9.9 Wh at 10.

Speed, flat 500 W, full 500 W, 15% kept 750 W, full 750 W, 15% kept
8 mph 76 mi 64 mi 72 mi 61 mi
10 mph 65 mi 56 mi 63 mi 54 mi
12 mph 56 mi 47 mi 54 mi 46 mi
15 mph 44 mi 37 mi 43 mi 37 mi
18 mph 34 mi 29 mi 34 mi 29 mi
20 mph 29 mi 25 mi 29 mi 25 mi

180 lb on the trike, throttle only, level pavement, 77 °F air. The kept columns hold back 15% of the pack, the high end of Addmotor's advice to recharge at "10%-15%".

Pedaling lengthens every row. The model counts 75 W as easy pedaling and 150 W as steady; with the motor idle, those efforts would carry a 180 lb rider on this 96 lb trike at about 9.9 and 13.9 mph on level ground, which shows which column you can hold.

Speed, flat 500 W, easy (75 W) 500 W, steady (150 W) 750 W, easy (75 W) 750 W, steady (150 W)
12 mph 150 mi legs alone 131 mi legs alone
15 mph 74 mi 199 mi 70 mi 165 mi
18 mph 47 mi 73 mi 46 mi 69 mi
20 mph 37 mi 51 mi 37 mi 49 mi

Each cell is a full pack, with 180 lb aboard on level pavement. Where a cell reads "legs alone", 150 W from you holds that pace with the motor idle. The cells above 100 miles rest mostly on your legs and on the motor's light-load losses, the least-checked part of the model (Limitations item 5).

Pick your pace first and your effort second; the assist level only sets how you and the motor share the work.

Does shifting gears save battery?

Only through the work your legs add. The motor turns the rear axle and your chain reaches it by its own path, so at a given speed and grade the pack spends less only when you pedal harder; the figures are the 500 W's:

Your ride Throttle only Easy pedaling (75 W) Steady pedaling (150 W)
12 mph, flat 11.6 Wh 4.3 Wh 0.0 Wh
15 mph, flat 14.8 Wh 8.8 Wh 3.3 Wh
12 mph, 4% grade 46.2 Wh 35.0 Wh 25.2 Wh
12 mph, 8% grade — — 66.8 Wh

Watt-hours from the pack per mile, 180 lb aboard, 77 °F air, on the 500 W. A dash means the model's 500 W cannot hold that pace on that grade by itself or with easy pedaling: 12 mph up 8% is past it, and the climbing table below gives the 9.8 mph it holds.

Choose the gear that keeps your cadence comfortable: a gear you can turn lets your legs take load off the pack, and at 12 mph on the flat a steady 150 W leaves the motor idle.

What does a climb cost the pack?

At 10 mph on the throttle, each 1,000 feet of climbing costs the 500 W's pack 167 to 189 Wh more than the same miles on the flat, on 4 to 6% grades. Lifting 276 lb, the 180 lb rider and the 96 lb trike, through 1,000 feet takes 104 Wh at the wheels; heat in the motor and the pack takes the rest.

Grade 500 W, per mile 500 W, full charge 750 W, per mile 750 W, full charge
2% 26 Wh 25 mi 24 Wh 26 mi
4% 45 Wh 14 mi 41 Wh 16 mi
6% 70 Wh 9 mi 61 Wh 11 mi
8% — past the model's motor 84 Wh 8 mi
10% — past the model's motor 112 Wh 6 mi
12% — past the model's motor 148 Wh 4 mi

10 mph and 180 lb on the trike in each row, throttle only. No energy is credited for the ride back down, so each row prices the uphill miles alone. A dash beside "past the model's motor" means that motor alone cannot hold 10 mph on that grade; the table below gives the pace it does hold.

On a grade, the motor sets your speed before the battery sets your miles. Each grade has a steady pace the motor can hold, and Addmotor's full 310 lb brings it down:

Grade 500 W, 180 lb 750 W, 180 lb 500 W, 310 lb 750 W, 310 lb
4% 14.9 mph 18.4 mph 11.7 mph 16.0 mph
6% 12.0 mph 16.3 mph 8.8 mph 12.6 mph
8% 9.8 mph 13.8 mph 6.9 mph 10.2 mph
10% 8.2 mph 11.8 mph 5.7 mph 8.5 mph
12% 7.0 mph 10.3 mph 4.9 mph 7.2 mph

The fastest pace the model's motor sustains on each grade, throttle only, with 180 lb or the full 310 lb aboard. Steady climbing with no run-up; torque held to 65 N·m on the 500 W and 90 N·m on the 750 W. At the 500 W's other published figure, 60 N·m, the 310 lb row at 12% would read "past the model's motor"; every other cell is unchanged.

On a 10% street, the 750 W keeps a 180 lb rider near 12 mph where the 500 W slows to about 8; with 310 lb aboard on the 500 W, shift low and add easy pedaling, which lifts its 12% pace from 4.9 to about 5.6 mph in the model.

A hilly day adds up as its level miles plus its climbs. On the 500 W's throttle, 20 miles at 12 mph on level ground take about 232 Wh, and 1,000 feet of climbing at 6% adds about 189 Wh: the day uses about 421 Wh, 76% of the 551 Wh in 85% of the pack.

Does rider weight affect the Citytan's range?

Load costs little on the flat and a great deal uphill. Extra pounds raise the tires' drag and the grade's pull but leave the air's drag alone, so a heavy load falls further behind a light one the steeper the road gets.

You plus your load 500 W, 12 mph 750 W, 12 mph 500 W, 15 mph 750 W, 15 mph
100 lb 64 mi 61 mi 49 mi 48 mi
130 lb 61 mi 59 mi 47 mi 46 mi
180 lb 56 mi 54 mi 44 mi 43 mi
220 lb 52 mi 51 mi 42 mi 41 mi
230 lb 52 mi 51 mi 41 mi 41 mi
260 lb 49 mi 49 mi 40 mi 39 mi
310 lb 46 mi 46 mi 37 mi 37 mi

The first column is you plus everything you carry; the model adds the trike's 96 lb on top, and every cell is throttle only on level pavement. The 230 lb row is Addmotor's rider limit and the 310 lb row its full payload.

From 180 lb to the full 310 lb, the 500 W's 12 mph ride drops from about 56 miles to 46, and its 15 mph ride from 44 to 37. Because Addmotor's "230+80 LBS" splits the payload between the rider on the saddle and the cargo in the basket, your own weight belongs inside the first number.

The trike's own weight moves the figures less. At the 112 lb Addmotor's post of August 30, 2025 printed, the 12 mph ride computes to about 54 miles on the 500 W and 53 on the 750 W, against 56 and 54 at the tab's 96 lb.

How much range does cold weather take away?

About a fifth at freezing. On the 500 W's throttle at 12 mph, the 56 miles of a 77 °F day shrink to about 44 at 32 °F and about 40 at 14 °F.

Air Pack energy vs 77 °F 12 mph flat, throttle
95 °F 99% 58 mi
77 °F 100% 56 mi
68 °F 98% 53 mi
50 °F 93% 48 mi
41 °F 91% 45 mi
32 °F 89% (80–93) 44 mi (40–46)
14 °F 82% (40–83) 40 mi (19–40)

The pack is taken to sit at the air's temperature, 180 lb aboard, level ground, 500 W. Each middle figure is the energy McMaster University measured from an LG HG2 cell at a 0.5C discharge at 77, 50, 32 and 14 °F, interpolated between; the brackets come from Samsung's cell data sheets and Casado and colleagues' 2025 measurements.

Three things change at once in the cold. At 32 °F the cells return about 89% of their 77 °F energy, 80 to 93% across the sources, and the air, by the gas law of the U.S. Standard Atmosphere, is about 9% denser.

The third is the rubber: the model raises rolling resistance 0.5% for each °F below 77 °F (0.9% per °C), a slope between Rothhämel's fit for a 42 mm tire and Bicycle Rolling Resistance's road-tire average, and holds it below 41 °F.

In winter, charge the pack indoors. Addmotor's maintenance guide asks for charging at 50 to 77 °F, and the pull-out case makes that a matter of carrying the pack, not the trike.

Do the tires or the riding position change the range?

On level ground the tire matters most. Addmotor calls the Citytan's tires "20" x 3.0" urban tires" in its post of July 15, 2026 and names no casing, so the model uses the field average Tengattini and Bigazzi measured on 273 everyday riders' commuter tires, bracketed by their slick-tire average and one standard deviation up.

Rolling resistance 12 mph flat, throttle 15 mph flat, throttle
0.0070 · slick tires, 137 everyday riders 57 mi 45 mi
0.0074 · commuter tires, 273 everyday riders (used) 56 mi 44 mi
0.0107 · commuter tires, one standard deviation up 46 mi 38 mi

The 500 W to an empty pack, 180 lb aboard on level ground. Addmotor's drawing shows a knobbed tread, so the bottom row is the one to read for a tire that rolls heavier than a commuter tire.

Keep the tires at the pressure printed on the sidewall. For the air, the model uses the drag area Tengattini and Bigazzi measured on 37 upright cruiser riders, 0.640 m²; their 0.603 m² for 90 mountain-bike riders would lift the 500 W's 12 mph ride from 56 miles to 58.

Addmotor's 50 and 65 miles, as steady rides

Addmotor's current figure is 50 miles, and an older one is 65 on PAS 1; in the model each reads as an unhurried steady pace. The Technical tab and the product FAQ say "50 Miles" and "Up to 50 miles per charge", and the launch post of March 27, 2025 printed "Up to 65 miles (PAS 1)".

Figure Motor Throttle Easy (75 W) Steady (150 W)
50 mi (tab) 500 W 13.4 mph 17.6 mph 20.1 mph
50 mi (tab) 750 W 13.1 mph 17.4 mph 19.9 mph
65 mi, PAS 1 (2025) 500 W 10.1 mph 15.8 mph 18.6 mph
65 mi, PAS 1 (2025) 750 W 9.6 mph 15.5 mph 18.4 mph

Each cell is the steady level-ground pace at which the model spends the whole 648 Wh across that distance, with 180 lb aboard. Neither figure states a speed or a rider weight, so each is set against a steady ride.

Read that way, Addmotor's 50 miles is a 13 mph ride on the throttle, and the older 65 miles a 10 mph one.

Plan on 85% of your row. Recharging "when it has a 10%-15% charge left", as Addmotor advises, keeps about 47 of the 500 W's 56 throttle miles at 12 mph.

To make the pack last longest, live between 20% and 80%. Addmotor's maintenance guide puts it as "keep your battery charge between 20% and 80% for the best lifespan"; that band holds 389 Wh, 60% of the pack:

Speed, flat 20–80% band, throttle 20–80% band, easy pedaling
8 mph 45 mi legs alone
10 mph 39 mi 287 mi
12 mph 34 mi 90 mi
15 mph 26 mi 44 mi
18 mph 21 mi 28 mi
20 mph 18 mi 22 mi

The 500 W inside the 20 to 80% band, 180 lb aboard on level ground. At 8 mph the easy-pedaling cell says "legs alone": this rider's 75 W by itself already rolls the trike at about 9.9 mph.

Your row first, 15% held back, each climb added on top. On the 500 W's throttle at 10 mph, 1,000 feet costs 167 to 189 Wh on 4 to 6% grades. Keeping that 15% back, a 180 lb rider on the throttle over level ground can count on about 47 miles at 12 mph, or 37 at 15.

Twenty miles at 12 mph with 1,000 feet of climbing at 6% comes to about 421 Wh on the 500 W's throttle, 76% of the 85% of the pack you plan on. Tell support@redtailebikes.com how far you go, how much you climb, what you carry and how fast you ride, and we will run that day through the model. Red with the 750 W is on this button; Orange 750 W is the same price.

The formula behind the range tables

A steady speed needs a steady flow of power at the rear wheels, and for constant speed in still air the model Martin and colleagues validated on an open road in 1998 gives it as:

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

P is the power at the wheels and v the road speed; m is the mass of trike, rider and load, g is gravity and θ the slope's angle; Crr is the tires' rolling resistance, ρ the air's density and CdA the rider's drag area. The brackets hold two terms, tires and slope first, air second, and three steps carry the figure back from the wheels to the pack:

  1. Your pedaling arrives at the wheels through the chain, which Martin and colleagues measured at 97.7% efficient, and the motor supplies the rest of what the ride needs.
  2. Each motor follows the published curve of a comparable unit, Bafang's RM G0H0: its 2021 OEM workbook gives 510 rpm unloaded and 426 rpm at rated load on 48 V, at an efficiency of "≥ 80" percent. Held at 48 V and the Citytan's 500 W or 750 W, the curve's unloaded speed is set so that 180 lb on the throttle on the flat just reaches Addmotor's 20 mph: 22.5 mph for the 500 W and 21.6 for the 750 W.
  3. The pack turns part of its energy into heat as it discharges, at the loss rate Arango, Lopez and Ceren measured on a 48 V pack.

Miles = 648 Wh × the usable share of the pack's energy at that temperature ÷ the watt-hours per mile, where the watt-hours per mile are the cells' watts divided by the speed in mph.

One ride worked from the tires back to the cells: 12 mph on the 500 W's throttle, 180 lb aboard, level pavement. Together rider and trike weigh 125.2 kg, and 12 mph needs 107.2 W at the wheels to hold: 48.7 W goes to rolling resistance and 58.5 W to the air.

At that pace the 22-inch rear tires turn at 184 rpm. Fitted to Bafang's published figures, the 500 W model carries 1.33 N·m of torque per amp, a 0.607 Ω winding and a 0.55 A no-load current, and this ride asks it for 5.6 N·m on 4.7 A at 79% efficiency, below its rated 80% because the load is light.

Add the pack's own losses and the cells supply 139.2 W, or 11.60 Wh for each mile at 12 mph; 648 ÷ 11.60 gives about 55.8 miles, and 47.5 with 15% held back.

The model earned its tables by reproducing two published results first:

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 first check is Appendix I of Martin and colleagues' paper (8.36 m/s, a 90 kg system, a 0.3% grade); the second is the RM G0H0's rated point in Bafang's workbook. At 82% efficiency instead, 2 points over Bafang's floor, the 500 W would carry the same 12 mph throttle ride 60 miles rather than 56 (Limitations item 4).

One owner recorded a ride to an empty pack, and the model sits beside it. In a review video of July 23, 2025, one of the three Addmotor shows on its Citytan page, IMBruceECLECTIC reports "17 or 18 mi for the way I ride it, which was PAS5 most of the day up and down the hills of Cecil County", with a 290 lb rider and about 10 lb of gear aboard.

Ride Conditions Miles to empty
IMBruceECLECTIC, July 23, 2025 290 lb rider and about 10 lb of gear; pedal assist level 5 most of the day, "a lot of 20 mph", the hills of Cecil County, Maryland 17 to 18
The model, throttle 300 lb, level pavement, 19.8 mph, the fastest the 500 W holds with that load 27
The model, easy pedaling (75 W) 300 lb, level pavement, 20 mph 33
The model, throttle 300 lb, level pavement, 15 mph 38

The model's level-ground figures for that load on the 500 W, the motor the video describes ("a bike that peaks around, 1100 watts"). The 300 lb aboard is inside Addmotor's 310 lb payload and above its 230 lb rider limit, so read the comparison for the model, never as a guide to riding over the limit.

The ride ended 33 to 36% short of the model's 27 miles at 19.8 mph, and the route explains the direction: "the hills of Cecil County", "a lot of 20 mph", and a last climb at 3 to 4 mph. The model prices a hilly day by adding each climb to the level miles, as the hills section does, so a route without its climbs reads long.

Folding it: 41.3 by 43.3 by 45.3 inches

The frame folds at a central hinge and the handlebar stem folds too, and Addmotor gives the folded trike as 41.3 inches long, 43.3 wide and 45.3 high. Its launch post of March 27, 2025 describes "a foldable step-through frame and handlebar stem", and its post of July 20, 2026 says it "Folds in under 30 seconds without tools" with a "Central hinge design".

Addmotor's photograph of the folded Citytan in a minivan's cargo area.

Addmotor's answer to the car question is "Generally yes, for larger vehicles". Its product FAQ says the folded size "easily slides into most SUVs, minivans, or RV storage compartments", and the photograph above shows one in a minivan.

At 96 lb, Addmotor's own advice is to roll it. The product FAQ says "It weighs 96 lbs with the battery", calls that "still substantial", and recommends "rolling rather than lifting it". Addmotor's answer of October 24, 2025 put it at "about 95 LBS (Include Battery)", and its post of August 30, 2025 printed 112 lb; all three are printed here.

Measure your cargo opening against all three folded figures before you order, the 45.3-inch height first. Sliding the pack out takes its weight off the trike before a lift, and the Citytri E-310 folds to 28.7 inches high if your car needs a lower load.

Check three numbers against your car: 41.3 inches long, 43.3 wide and 45.3 high, folded. Roll the 96 lb trike to the car rather than carry it, and slide the pack out before you lift it in.

Carrying: 230 lb on the saddle, 80 in the basket

Addmotor splits the 310 lb payload as "230+80 LBS" on its Technical tab: the rider and 80 lb of cargo. Its post of November 25, 2025 spells it out as "230 lbs on the trike itself plus 80 lbs on the rear rack".

The rear basket ships with the trike; the front basket does not. The product FAQ says "It includes the battery and rear cargo basket; the front basket is separate", and email us if you want the front basket quoted with your order.

A trailer carries more. The same FAQ calls the trike "fully compatible with the new Addmotor trailer", and Addmotor's feature copy credits the rear frame's 7020 reinforcement with support for "increased payloads, including trailer towing capacity". We will quote the trailer with the trike.

What each load costs in miles is in the weight table, whose 230 lb row is the heaviest rider Addmotor's split permits.

Brakes, lights and turning

Three mechanical discs with 180 mm rotors, plus a parking brake. The Performance tab lists "Mechanical Disc Brakes On Each Wheel" and a parking brake, and Addmotor's post of July 20, 2026 gives the set as "Triple mechanical disc (180 mm rotors)".

Addmotor's image of three mechanical disc brake calipers mounted over three drilled steel rotors, one for each wheel

The three calipers and rotors, in Addmotor's image.

Set the parking brake and the trike stays put on a slope. Addmotor's feature copy describes it as letting you "safely and securely immobilize your trike, whether you're taking a break or parking on an incline".

Addmotor's close-up of the Citytan's parking brake system: a polished, ribbed metal pin set in a black housing

There is no reverse. Addmotor answered on March 29, 2025 "no, there is no reverse mode", and the product FAQ suggests turning the trike around by hand with the parking brake set on a slope.

Take the first rides slowly. Addmotor's guidance for riders new to its trikes, in its post for new riders, is to start somewhere with "no obstacles or tight turns".

Both lights draw on the main pack. Addmotor's Performance tab describes a "48V LED Headlight. Powered by the main battery and controlled through the display panel.", and its image shows a red LED taillight under the basket.

An 80 mm fork on 20 × 3.0 tires

The fork carries the suspension, and all three tires are 3 inches wide. The Performance tab lists an "ADDSHOX Oil Spring Suspension Fork", and the feature copy says "The 80mm of travel absorbs shocks and bumps"; under the rider, the tab lists a "Spring Saddle".

Addmotor's close-up of the Citytan's front end: the black ADDSHOX suspension fork holding a 20-inch wheel with a disc rotor and an amber reflector, below the frame's ADDMOTOR lettering

Three-inch tires on 20-inch wheels: "20" X 3.0"" on the Size & Fit tab, which Addmotor's post of July 15, 2026 calls "urban tires". In the range model, the tread is one of the larger levers on your miles.

The Mercer fit test

The same seven people, the Mercers, stand beside every machine we review, so a fit answer on one page compares with the next. For the Citytan, each verdict rests on Addmotor's published window, saddle heights, standover or payload, or on the fit tables that build on them.

Member Age · Height Verdict The number behind it
Frank Kowalski 63 · 5'10" Outside the window Addmotor's window ends at 5'9"; the Citytri E-310 Plus runs to 6'1"
Ruth Kowalski 61 · 5'5" Inside; measure the inseam The formula wants 33.8 in from the saddle to the pedal; at her height, at least 25 of 100 riders need more than the top setting reaches
Jack Mercer 48 · 6'1" Outside the window Addmotor's window ends at 5'9"
Dana Mercer 45 · 5'7" Inside; measure the inseam The formula wants 35.1 in for her height's median leg, more than the top setting's 34.6 in off the ground
Maya Torres 32 · 5'6" Inside; measure the inseam The formula wants 34.5 in; at her height, at least 46 of 100 riders need more than the top setting reaches
Cole Mercer 16 · 5'11" Outside the window, and set by his state Addmotor's window ends at 5'9", and his state's age rule decides whether a 16-year-old may ride
Ivy Mercer 12 · — Not as a passenger; as a rider, her state decides One saddle; her state's age rule decides whether a 12-year-old may operate an e-bike

Ruth, Dana and Maya fall inside the 5'1" to 5'9" window, and each should check a barefoot inseam against the ceiling table before ordering. The household's taller riders are better served by the Citytri E-310 Plus, sized to 6'1".

Has it been recalled?

No. On October 11, 2026, none of the 10,047 recalls on the Consumer Product Safety Commission's full recall list, June 8, 1973 to October 8, 2026, named Addmotor, the Citytan, its M-315 code or its SKUs EB3157, EB3152, EB3155, EB31577, EB31572 and EB31575.

Each of those records was read in every field, for Addmotor, ADDMOTOR, Add Motor, Addmotor Tech, Motan and Addrider, for 19 Addmotor model families with the Citytan's among them, and for every model code Addmotor uses. Only "M300" turned up, in two records about laptops: Sony's 2006 recall of notebook batteries names the Toshiba Portege M300, and Compaq's 2001 recall of power adapters names the Armada M300.

As a control, three makers with recalls on file went through the same search, and it found 1 record for Ancheer, 79 for Specialized and 40 for Trek. The CPSC keeps warnings on a list of their own, the product safety warning listing: none of its 375 entries names Addmotor or the Citytan, and checked against a brand that carries two published warnings, the same read turned up both.

Class and road rules for a 500 W or 750 W, 20 mph three-wheeler

Which motor you buy changes how many states' definitions take the trike in. Addmotor's page lists a 500 W or 750 W motor, a throttle and 20 mph, and the federal definition draws its lines at 750 watts and 20 mph.

15 U.S.C. § 2085(b) defines 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 top speed on the motor alone, with a 170-pound rider on paved level ground, is "less than 20 mph".

Fully operable pedals pedals, a chain and a Shimano 7-speed
A motor of less than 750 watts "500W Rear-Drive Motor (1100W Peak)" or "750W Rear-Drive Motor (1400W Peak)"
Less than 20 mph on motor power, 170 lb rider "20 Mph"

Left column: § 2085(b) in its own words; right column: Addmotor's Citytan page; both read October 11, 2026.

The 500 W sits under the federal watt line; the 750 W sits on it, and the statute writes both lines as "less than". The statute measures that speed on motor power alone with a 170-pound rider aboard; Addmotor's tab gives the top speed as "20 Mph" without a rider weight.

California's line includes the cap. Its Vehicle Code § 312.5(a), read September 28, 2026, gives an electric bicycle "an electric motor that does not exceed 750 watts of power", and § 231 allows a bicycle "one or more wheels" and adds "An electric bicycle is a bicycle."

Across the 50 states and DC, the 500 W is inside 36 definitions and the 750 W inside 26. We screened every definition on October 11, 2026 for its watt wording, throttle rule, top speed and wheel count, and Pennsylvania's for its weight limit:

Addmotor's figures fall… 500 W ($1,099) 750 W ($1,499)
Inside the e-bike definition 36: AZ, CA, CO, DC, DE, FL, GA, HI, IA, IN, KS, LA, MA, MD, ME, MI, MN, MS, NC, ND, NE, NM, NV, OK, OR, PA (at 96 lb), SC, SD, TN, TX, UT, VA, WA, WI, WV, WY 26: CA, CO, DC, DE, GA, HI, IA, IN, MA, MD, MI, MN, NC, ND, NE, NM, NV, OK, OR, PA (at 96 lb), SC, SD, UT, VA, WA, WI
Outside it 4: AL, MT, NJ, RI 22: AL, AR, AZ, FL, ID, IL, KS, LA, ME, MO, MS, MT, NH, NJ, NY, OH, RI, TN, TX, VT, WV, WY
Open for a three-wheeler 9: AR, CT, ID, IL, MO, NH, NY, OH, VT 1: CT
No e-bike definition 2: AK, KY 2: AK, KY

From the definitions in our state law atlas, screened October 11, 2026. "Open" means the definition's words do not settle a three-wheeler.

With the 500 W, the four outside are Alabama, Montana and Rhode Island, which name two wheels, and New Jersey, which also allows assistance only while you pedal. With the 750 W, nineteen of the 22 outside set the motor limit at "less than" or "fewer than" 750 watts, Alabama among them, and the other three are Montana, Rhode Island and New Jersey, for the same reasons as with the 500 W.

Pennsylvania turns on weight, and Addmotor's documents put the trike on both sides of the line. 75 Pa.C.S. § 102 covers "A vehicle weighing not more than 100 pounds with two or three wheels more than 11 inches in diameter"; Addmotor's tab says 96 lb, under that line, and its August 30, 2025 post said 112 lb, so Pennsylvania riders should email us before ordering.

Connecticut's line moved on October 1, 2026, when Public Act 26-24 § 26 set the motor at "not more than seven hundred fifty watts", while § 14-1 defines no "bicycle", leaving the wheel count open; email us and we will confirm how Connecticut treats a three-wheeler.

On December 1, 2026, North Carolina splits its definition into three classes, and the Citytan's two motors fall inside before and after: Session Law 2026-46 still covers a bicycle "with two or three wheels" and "an electric motor of no more than 750" watts.

Outside a state's e-bike definition, a trike still falls under its road code, as a moped or another class with its own rules. Our 50-state e-bike law atlas gives every state's answer, and our California e-bike law page goes furthest into a single state.

Before riding anywhere, check your state's row above and open its page. The 500 W sits inside the e-bike definition in 36 jurisdictions and the 750 W in 26; if your state is in neither list, send us its name and the reply will carry its rule.

Trails, parks and public land

Off the street, the Citytan goes where the land's manager allows it. A park path, a boardwalk or a campground road is open to it only where that place's own rule admits an e-bike.

Federal land splits two ways: the Bureau of Land Management has its own e-bike definition, and the Forest Service settles e-bike access district by district. 43 CFR 8340.0-5 gives BLM's as "a two- or three-wheeled cycle with fully operable pedals and an electric motor of not more than 750 watts (1 h.p.)", which takes in both of the Citytan's motors.

A field office may treat e-bikes as bicycles, yet the off-road vehicle rules stay lifted only while, as the regulation puts it, "the motor is not exclusively propelling the e-bike for an extended period of time".

On BLM ground, then, pedal along: long stretches on the half-twist throttle by itself are what that condition excludes. Once the exception stops applying, 43 CFR 8341.1 keeps an off-road vehicle to land designated "open to off-road vehicle use".

The Forest Service directives of March 31, 2022 govern National Forests: the notice at 87 FR 41278 records them as "managing all classes of e-bikes as motor vehicles", and a Ranger District with a motor vehicle use map then applies 36 CFR 261.13, which forbids riding "other than in accordance with those designations".

Where you plan to ride Who decides What to read
A city or county park path the park agency its posted e-bike rule
A campground or RV park the campground's operator its posted rule
Private land the owner the owner's permission
A National Forest road or trail the Ranger District its motor vehicle use map (36 CFR 261.13)
BLM land the field office its e-bike decision and its open, limited and closed designations (43 CFR 8341.1)

Whatever the right-hand column names has the final word.

The penalty side sits in 43 CFR 8340.0-7: "a fine of not more than $1,000", imprisonment "for not longer than 12 months", or both, for a breach of the off-road vehicle rules in subparts 8341 and 8343. Our public-land e-bike guide lays out each agency's version.

Green flags

Red flags

Each item below is about fit: the rider the Citytan does not suit, and where that rider goes next.

  • Wrong if you stand over 5'9". The Citytri E-310 Plus is sized from 5'3" to 6'1" in Addmotor's table, $1,699.
  • Wrong if your barefoot inseam is over about 31.7 inches. The top saddle setting falls short of the 109% formula for that leg; the Citytri E-310 lists a 36.6-inch top setting, and we will run your inseam against either trike.
  • Wrong if one charge must cover far more than 50 miles. There is no larger pack for the Citytan; the Citytri E-310 carries 960 Wh from $1,599.
  • Wrong if your car's cargo opening is under 45.3 inches high. The Citytan folds to that height; the Citytri E-310 folds to 28.7.
  • Wrong if you weigh more than 230 lb. The Grandtan M-340 is rated "350+100 LBS" in Addmotor's split, from $2,199.
  • Wrong if two adults want to ride at once. The Soletri II seats two on a banana bench at $2,699, and the M-380 tandem puts two riders in line, from $3,899.
  • Wrong if you want to sit back against a backrest. The Arisetan II M-360 is a semi-recumbent with a "Saddle with Backrest", from $2,399, and the Freetan M-368X adds full suspension at $3,199.
  • Wrong if your streets climb past 6% and you want to keep pace on the 500 W. Take the 750 W at $1,499, which holds about 11.8 mph up 10% with a 180 lb rider.

Buy it if / Buy something else if

Buy it if you stand 5'1" to 5'9" with a barefoot inseam up to about 31.7 inches, want a trike that folds for a minivan, an RV or a small garage, and want the 14.1-inch step, a differential and a parking brake, with about 56 miles at 12 mph on the 500 W's throttle on level ground for a 180 lb rider.

It asks for a rider at 230 lb or less with up to 80 lb in the basket, a state whose words take in a 500 W or 750 W, 20 mph trike, a plan for moving 96 lb, rolled as Addmotor advises, and an outlet indoors for a charge of about 6.75 hours from empty.

For $1,099, $400 under the $1,499 regular price, you get a 500 W rear-drive motor with a 1,100 W peak, a 648 Wh pack, a folding frame, an 80 mm fork, a disc on each wheel, a differential, a parking brake and a rear basket; $1,499 brings the 750 W.

On Shop Pay's 12-month sample plan our listing shows $99.19 a month at 15% APR, $1,190.28 in all, for the 500 W, and $135.30 a month, $1,623.60 in all, for the 750 W.

Buy something else if you are over 5'9" or need far more than 50 miles a charge, where the Citytri E-310 runs from $1,599; if you weigh over 230 lb, where the Grandtan M-340 starts at $2,199; or if you want to sit back against a backrest, where the Arisetan II M-360 starts at $2,399.

Addmotor's other trikes and bikes on our shelf sit beside the Citytan in our Addmotor brand profile, and every trike and e-bike we review is gathered in our e-bike reviews hub.

Before you buy: the checklist

Run these ten checks before spending $1,099 or $1,499; the first three settle whether, and where, the trike may be ridden.

  1. Find your state's row in the class table for your motor, then its page in our law atlas for the full rules.
  2. Get the rule from each park, campground or trail you plan to use; whoever manages that ground has the say.
  3. Measure your barefoot inseam and read the saddle and ceiling tables; over about 31.7 inches, look at the Citytri E-310, whose top setting sits higher.
  4. Step on a scale: the saddle takes up to 230 lb and the basket up to 80.
  5. Pick the motor for your steepest regular climb: the climbing table gives each motor's pace.
  6. Measure the car's cargo opening against 41.3 by 43.3 by 45.3 inches, folded.
  7. Plan the move: roll it, as Addmotor advises, and slide the pack out before any lift.
  8. Price your usual ride in the range tables, climbs included, with 15% of the pack left unused.
  9. Choose where it charges: indoors, at 50 to 77 °F, for about 6.75 hours from empty.
  10. Plan the first ride somewhere with "no obstacles or tight turns", as Addmotor's post for new trike riders advises.

Assembly is the last 20%. Addmotor's product FAQ says the trike "arrives 80% pre-assembled" and that "final setup takes under 30 minutes", and its answer of March 31, 2025 gives the same 80%; email us if a step stalls and we will walk you through it.

A change of mind is handled under our refund policy: ask within 72 hours of delivery, with the trike still sealed in its factory packaging, and the refund is the price less a 15% restocking fee and return shipping, while canceling an order carries a 3% transaction fee. That is the reason to send us your fit, load and route questions before you buy.

Every price, plan and term in this section is our store's, read October 11, 2026. If anything fails, you deal with us and we deal with Addmotor; the Cyan 750 W is $1,499.

Frequently asked questions

How far can the Addmotor Citytan go on one charge?

Addmotor's Technical tab says "50 Miles". On the throttle over level pavement, the model gives a 180 lb rider about 56 miles at 12 mph on the 500 W and 54 on the 750 W, 29 at the 20 mph top on either, and about 46 at 12 mph with the full 310 lb aboard; each 1,000 feet climbed at 10 mph takes 146 to 194 Wh on the throttle (the range tables).

What is the difference between the 500W and 750W Citytan?

The motor and the price: $1,099 for 500 W (1,100 W peak) and $1,499 for 750 W (1,400 W peak), on the same frame and 648 Wh pack. On level ground they give nearly the same miles; up 10% with a 180 lb rider the 750 W holds about 11.8 mph and the 500 W about 8.2, and the 500 W sits inside more states' e-bike definitions (which motor).

How much does the Addmotor Citytan weigh?

96 lb with the battery, "96 LBS (Include Battery)" on the Technical tab; Addmotor's answer of October 24, 2025 gave "about 95 LBS (Include Battery)" and a post of August 30, 2025 printed 112 lb. Addmotor recommends rolling it rather than lifting it (folding).

Will the Citytan fit in a car trunk?

Folded, it measures 41.3 inches long, 43.3 wide and 45.3 high, which Addmotor's FAQ fits to "larger vehicles" such as "most SUVs, minivans, or RV storage compartments". Measure your cargo opening against all three; for a lower load, the Citytri E-310 folds to 28.7 inches high (folding).

How do you fold an electric trike like the Citytan?

By Addmotor's description, the frame and the handlebar stem both fold, around a central hinge, in "under 30 seconds without tools". Slide the pack out first to lighten the trike, and roll it to the car rather than carry it, as Addmotor advises (folding).

Is the Citytan a good folding trike for seniors?

Fit decides it more than age: Addmotor's 14.1-inch step and 5'1" to 5'9" window, which the fit section puts in numbers. The Mercers' 61-year-old fits inside the window, and its 63-year-old, at 5'10", is past it (the Mercer fit test).

Is there a bigger battery for longer rides?

No. Addmotor answered on April 22, 2025: "Not for this one. But we have another model with bigger battery like the citytri." The Citytri E-310 carries 960 Wh against the Citytan's 648 (the comparison).

Does the Citytan have a reverse mode?

No. Addmotor answered on March 29, 2025: "no, there is no reverse mode." Its product FAQ suggests turning the trike by hand, with the parking brake to hold it on a slope (brakes).

How hard is the Citytan to assemble?

Addmotor's FAQ says it "arrives 80% pre-assembled" and that "final setup takes under 30 minutes", and its answer of March 31, 2025 gives the same 80%. Email us your questions as you build and we will answer each step.

What is the weight limit of the Citytan?

230 lb for the rider and 80 lb of cargo, "230+80 LBS" on Addmotor's Technical tab, 310 lb in all. At 310 lb on level pavement, the 500 W's 12 mph throttle ride computes to about 46 miles (the weight table).

How high does the Citytan's saddle go, and will it fit my leg?

From 28.7 to 34.6 inches off the ground, on Addmotor's Size & Fit tab. A 5'8" rider with the median inseam for that height, 32.6 inches, needs the saddle top 35.6 inches from the pedal by the 109% formula, past the top setting; in general, a barefoot inseam over about 31.7 inches asks for more than the post reaches (the saddle tables).

Your state's words decide. On October 11, 2026, Addmotor's figures sit inside the e-bike definitions of 36 jurisdictions with the 500 W and 26 with the 750 W, California's "does not exceed 750 watts" among both (the class table). Tell us your state by email; the answer will quote that state's own words.

Is the Addmotor Citytan M-315 worth it?

If you fit the 5'1" to 5'9" window and want a trike that folds, the case is $1,099 for the 500 W against a $1,499 regular price, about 56 miles at 12 mph on the throttle on level ground for a 180 lb rider, and $99.19 a month over 12 months on Shop Pay at 15% APR (the verdict).

Limitations of this review

Twenty points this review leaves open:

  1. We sell this trike. Read the red flags first; they count as much as the green.
  2. Specification-verified throughout: the sources behind each figure are Addmotor's published documents, statutes, our store record, the studies cited in the range and fit sections, and the arithmetic set out on this page.
  3. Each range row is a single steady ride: one speed, one grade, still air, no stops. Starting from rest, riding into wind or crossing grass all cost more.
  4. Both motors are modeled on a stand-in, a Bafang motor's published curve. Addmotor publishes its motors' ratings, peaks and torque, not their speeds; at 82% efficiency, 2 points over Bafang's 80% floor, the 500 W's 12 mph throttle ride would go 60 miles rather than the table's 56.
  5. The model is least certain when your legs do most of the work. If your legs carry most of the load, as in the 12 mph easy-pedaling column, the answer hangs on the motor's light-load losses, which fall between the rated and no-load points Bafang's workbook publishes.
  6. The model caps each motor at its rated watts. The 1,100 W and 1,400 W peaks are not used, so on a short, steep pitch either motor may climb faster than the climbing table's steady paces.
  7. Each motor's unloaded speed is set from Addmotor's 20 mph: in the model, a 180 lb rider on the throttle just reaches it. A real motor that is faster but capped by a limiter would draw slightly differently close to 20 mph.
  8. The one recorded ride is a hilly day above Addmotor's rider limit. It is printed beside the model's level figure in the formula section, with its conditions, and it checks the model's direction more than its size.
  9. Every table assumes all 648 Wh can be used. How much of the pack the battery management actually releases is not in Addmotor's documents; researchers at KIT, running one pedelec through a standard bench range test, measured 75% in use.
  10. The rolling-resistance figure is a field average, everyday riders' commuter tires, not a drum measurement of the Citytan's 20 × 3.0, and Addmotor's drawing shows a knobbed tread; the tire table shows how far the answer moves.
  11. One laboratory cell anchors the cold table. Because the pack's cell model is not named, its middle line follows McMaster University's measurements of an LG HG2, and Samsung's and other published data set the brackets.
  12. Nothing is measured on the size drawing. Its seven arrows imply 16.4 to 19.2 pixels per inch, and scaled by any one of them it matched at most two others within 3.5%, so the saddle table stops at the formula's distance and a tape measure finishes the job.
  13. The ceiling table is a floor. It assumes nothing about the pedal's height off the ground, which only adds riders who cannot reach the formula at the top setting.
  14. Lean and hand load are not computed. Without a published seat angle, bracket height or grip position, those two subsections give guidance instead, and their hand-load figure comes from racers in a stretched posture the Citytan's tall bar does not ask for.
  15. Use each saddle distance as a first setting. The table applies the 109% rule to your height's median inseam; on the trike, the heel check carries you the rest of the way toward a 25 to 35 degree knee range.
  16. The fit tables rest on a survey of soldiers. The 6,068 people ANSUR II measured between 2010 and 2012 were 17 to 58 years old and do not sample the US public, so pick your row by your own inseam.
  17. Addmotor's documents give the 500 W two torque figures and the trike three weights: 65 and 60 N·m, and 96, 95 and 112 lb. All are printed; the model uses the tab's 96 lb and the tables' 65 N·m, and the climbing note shows the one cell the lower torque moves.
  18. Addmotor names no certificate for the Citytan's pack on its tabs; its July 20, 2026 post rates the potting material UL94 V-0, a flammability rating for plastics, and we will ask Addmotor for the pack's own document on request.
  19. The class table follows each state's definition as our law atlas records it, screened October 11, 2026. States rewrite their words (Connecticut on October 1, North Carolina on December 1), and three-wheeler language outside a definition section was not read in every state.
  20. Prices, stock by motor and Shop Pay terms are as read on October 11, 2026, while Addmotor's site was running its Prime Month sale; when Addmotor moves a Citytan price, ours moves with it, and so do the monthly figures.

The bottom line

At $1,099, the Citytan M-315 puts a 500 W rear-drive motor and a 648 Wh pack on a frame that folds to 41.3 by 43.3 by 45.3 inches, with a 14.1-inch step, an 80 mm fork, a disc on each wheel, a differential, a parking brake and a rear basket; $1,499 swaps in the 750 W for streets that climb.

The model puts a 180 lb rider on level pavement at about 56 miles at 12 mph on the 500 W's throttle and 54 on the 750 W's, and the full 310 lb at about 46; up 10%, the 750 W holds about 11.8 mph where the 500 W holds 8.2.

Its owner stands 5'1" to 5'9" with a barefoot inseam up to about 31.7 inches, needs a trike that folds for the car or the closet, rides where the state's words take in the chosen motor, and has a plan for moving a 96 lb trike. Paid monthly, the 500 W runs $99.19 for 12 months at 15% APR on Shop Pay's sample plan.
