Addmotor Soletan M-66X Review: $1,799 Banana-Seat Bike

Banana-seat e-bike · 750 W · $1,799 · a 23.5-inch banana seat · a 17-inch step · full suspension · one 48 V 20 Ah Samsung pack, 960 Wh · torque sensor and half-twist throttle · 300 lb payload · 20 mph · verified October 2, 2026

Quick Answer — Addmotor's Soletan M-66X is a $1,799 full-suspension e-bike with a 23.5-inch banana seat and a 300 lb payload for riders and cargo together. At 12 mph on the throttle over level pavement, its one 960 Wh pack computes to about 67 miles for one 180 lb rider and 55 for two totaling 300 lb.

Addmotor sizes it for riders 5'2" to 6'2", and the seat sits at one height, 32.5 inches, with no post to move: low enough that most riders in that window put their feet down at a stop, and below the height a pedaling formula sets (the fit section). Who may ride behind you is your state's call, quoted in the passenger section.

How we verified this Addmotor Soletan M-66X review

The specification comes from Addmotor's Soletan page, re-read on October 2, 2026 with its tabs, stat strip and colorway matrix, from its size drawing, the bike's question board and the 45 Addmotor posts that name the Soletan. Our own price, colorways and Shop Pay plans were read the same day.

Range and fit are computed, every formula's inputs printed beside it. This review is specification-verified: each figure traces to Addmotor, a statute, our store or arithmetic shown here. We sell this bike, so weigh the red flags as carefully as the green.

Addmotor's Soletan M-66X specification

One step-through frame in five colorways, one pack, and a Size & Fit table with a single saddle height.

Addmotor's Size & Fit tab, read October 2, 2026; every row also appears on the size drawing.

Read on October 2, 2026 from Addmotor's Technical and Performance tabs, its stat strip, its images and its question board; where two of them word an item differently, both are quoted.

A 23.5-inch banana seat over a 17-inch step

The Soletan is a two-wheeler built around one long seat: a banana seat 23.5 inches from nose to tail, with room on it for a second rider. Addmotor's page calls it a "Full Suspension Electric Moped Bike For Adults", and its banner sells it as "the full-suspension e-bike for two".

Below the seat the frame drops to a wooden footboard, 17 inches up on the size drawing. You step onto the board, sit back onto the seat, and the pedals turn under its front edge.

The banana seat in Addmotor's close-up; the drawing gives it 23.5 by 8.5 inches.

The seat bolts to the frame and does not move. Addmotor prints one saddle height, 32.5 inches, and its drawing and photographs show the seat on its frame tubes with no seatpost. The cockpit is what adjusts: Addmotor lists an "Adjustable Alloy Stem" and a U-shaped bar that changes "The Angle and Height".

A passenger rests their feet on pegs. Asked about them, Addmotor answered on January 16, 2025: "Yes, Soletan e-bike has rear footpegs." The Soletri II, reviewed here, puts a banana seat of the same 23.5-inch length on three wheels; the Soletan is the two-wheeled version, about 112 lb against the trike's 130, with a 30-inch bar as its widest published figure against the trike's 32.7-inch total width.

Does the Soletan fit you? One seat height, 32.5 inches

At 32.5 inches the seat sits below the height a pedaling formula sets for every rider in the survey from 5'2" to 6'2", 3.7 inches low for the median 5'2" rider and 10.9 inches for the median 6'2" rider. In return, a low seat brings the ground within reach: seated, 56 of every 100 riders at 5'8" put both feet flat.

The formula is the saddle 109% of your inseam from the pedal, the setting Peveler and colleagues describe as a cyclist's most efficient position. On a seat below it, the knee stays bent at the bottom of every stroke. A fixed moped-style seat trades that for a seat you sit down onto and a short reach to the ground, so the gap matters most to a rider who means to pedal hard for miles.

Three steps place you on it:

1. Measure your inseam barefoot. Stand against a wall, press a hardcover book up between your legs the way a saddle sits, and measure from the floor to its spine.
2. Find your height in the tables below and read how far the seat sits from your row's formula height, and whether you reach the ground.
3. Decide how you will ride it. On the throttle and the lower assist levels your legs do a small share of the work; for long, hard pedaling, the gap is the number to weigh.

Addmotor's size drawing over its studio photograph of the Pearl White Soletan. Its total length, seat length, saddle height, standover and handlebar height agree with the photograph within 3.5 percent at the wheelbase's scale; the controls table prints every comparison.

How high does my saddle go?

It stays at Addmotor's 32.5 inches, so the table measures each rider against the seat. The bodies are the 6,068 of the US Army's anthropometric survey, placed on the geometry measured from Addmotor's drawing.

Floor-to-seat height the formula sets for the median rider at each height, how far Addmotor's 32.5-inch seat sits from it, and how many of 100 riders have the seat between 106% of their inseam, the low end of the range Ferrer-Roca and colleagues cite, and 110.4%, the top of the range they propose. Typical inseam spans the middle 90 of every 100 bodies, men and women pooled.

The seat meets the 109% setting for a 26.2-inch inseam, and the 106% end of the band for 26.9 inches. Every rider in Addmotor's window has a longer leg than that, so every one pedals with the knee more bent than the formula sets it; at 5'8" the median rider sits 7.2 inches under it.

The same low seat is what puts your feet on the ground. Seated at 32.5 inches, a barefoot inseam reaches the floor flat-footed for 20 of every 100 riders at 5'6", 56 at 5'8" and 90 at 5'10"; at 5'2" the median rider is about 3 inches short and stops on the balls of the feet or slides forward onto the footboard.

Can I step through it at a stop?

Yes, at every height in the window. The footboard sits 17 inches off the ground, so even at 5'2", 95 of every 100 riders clear it by 11.0 inches or more.

Barefoot inseam against Addmotor's 17-inch standover, from the same 6,068 bodies: the inseam column is each height's median, and the last column counts riders whose inseam clears the board.

There is no top tube to swing a leg over. You walk onto the board between the seat and the bars, then sit back, the way you would mount a scooter.

Will I lean forward to reach the bars?

No: every rider in the table reaches the grips sitting straight up, with the elbows bent. Measured on Addmotor's drawing, the grips sit 7.6 to 8.2 inches ahead of the crank axle and about 30.7 inches above it, close to a rider sitting a few inches back on the seat.

The lean is the smallest trunk angle at which a straight arm meets the grip; the middle column counts riders who reach it sitting straight up, and the last gives the median elbow bend among them.

The bars come back to you, so your arms fold to about a right angle. That is a cruiser's posture; Priego Quesada and colleagues had twenty recreational cyclists rate three trunk positions, and the most upright was rated most comfortable. If your elbows want more room, Addmotor's stem and bar both change angle.

How much weight goes through my hands?

About 6 to 7 percent of your body weight with your back relaxed, four to seven pounds on each hand. In Carahalios's 2015 laboratory study, ten road racers on their brake hoods carried 15% on the bars, more than twice that.

Computed body by body from the segment weights Clauser and colleagues published in 1969: the arms' weight goes forward onto the grips, so each figure is an upper bound. The bracket covers the grip positions measured on the drawing.

On a long ride, gloves help: across 36 riders, Slane and colleagues found padded gloves cut palm pressure by 10 to 28%.

How do I set the saddle at home?

Nothing on the seat adjusts, so your setup is how far back you sit and how the bars are angled. Sitting toward the rear of the 23.5-inch seat lengthens your reach to the bottom pedal slightly, at the cost of seat length for a passenger.

With one pedal at the bottom of its stroke, look at your knee: the cycling literature recommends a pedaling knee at 25 to 35 degrees of bend, and on this seat most riders will sit past that. Then angle the stem until your shoulders drop, ride a few blocks, and only then move anything again.

The fit arithmetic, step by step

Three rules sit under every figure above: a seat 1.09 times your inseam above the pedal, a lean equal to the least trunk angle that lets a straight arm meet the grip, and a hand load equal to the upper body's weight carried forward over the reach.

Take a 5'8" rider on the median 32.6-inch inseam. The formula puts the seat 35.6 inches from the pedal at the bottom of the stroke; less the 175 mm crank measured on Addmotor's drawing, that is 28.7 inches from the crank axle.

The sitting point is 5.6 inches behind the crank axle on the drawing, so the distance is read on the slant: above a crank axle 11.6 inches off the ground, the formula wants the seat top 39.7 inches up, against the Soletan's 32.5.

LeMond's rule, 88.3% of inseam from the crank axle, gives 28.8 inches for the same rider, within two tenths of an inch of the 109% figure.

Addmotor prints no crank length, bracket height or seat angle, so they are measured on its drawing, scaled by the 48-inch wheelbase from front axle to rear axle; both wheels stand on the bike's centerline, so no perspective correction applies to them. Addmotor's other printed dimensions then check the scale:

Five of six printed dimensions agree with the photograph within 3.5 percent, measured from where the tread meets the ground; measured instead from the line where Addmotor's arrows end, 13 pixels lower, three still do. The tire is the miss, 6.3% under its nominal size, and the grip's height is taken from Addmotor's 43-inch label, since the near grip stands closer to the camera than the frame.

A 750 W rear-mounted motor, a torque sensor and a twist throttle

Addmotor rates the motor at 750 W and prints its peak as 1,300 W and its torque as 80 N·m. The Technical tab lists a "48V*750W Rear-Mounted" motor, the stat strip a "Rear Brushless Motor 750W", and the page's 66x-ebike image adds "1300W Peak Motor Power" and "80Nm Torque". Addmotor's post of November 5, 2025 gives the same three numbers.

The rear-mounted motor marked in blue in Addmotor's image.

The motor tile from Addmotor's key-features image.

The motor answers your legs through a torque sensor: the Performance tab lists an "Intelligent 7 Levels Pedal Assist System with Torque Sensor (7 PAS)". A sensor that reads how hard you press gives more help the harder you push, so on this bike a light, steady effort on a low level is the way to stretch the range.

You can also ride with no pedaling at all. Asked whether the throttle twists or presses, Addmotor answered on October 19, 2023: "twist throttle". An "Addmotor EB 2.0 25A Controller" sits between the pack and the motor, and the bar carries an EB 2.0 LCD display.

One 960 Wh Samsung pack, UL 2271 on the stat strip

Forty-eight volts at 20 amp-hours makes 960 watt-hours, and every range figure on this page comes from that one pack. The Technical tab lists a "48V*20Ah Samsung UL-certified Battery", and the stat strip names the standard, "UL 2271".

The 48 V 20 Ah Samsung pack in Addmotor's key-features image.

Addmotor sells the same pack on its own page, a "48V*20Ah Samsung UL-Certified Battery Pack" whose description lists "SOLETAN M-66X" among the bikes it fits. On that page, Addmotor answered on October 17, 2025: "The battery weighs 6 kg (about 13.2 lbs). Its dimensions are roughly 38 x 8 x 12 cm."

The charger is "48V*2.0A 5 Pins US Standard DC Charger 5 Pins With Auto Magnetic Suction", and the port is a "5 Pins With Auto Magnetic Suction Customized Snap Lock". Addmotor's charging advice, quoted in the range section, is to recharge at 10 to 15% left and keep the pack between 20 and 80% for its lifespan.

Range: how far a charge takes the Soletan

On level pavement with the throttle alone, the pack carries a 180 lb rider about 67 miles at 12 mph and 39 at 20 mph, and two riders totaling 300 lb about 55 miles at 12 mph. Easy pedaling at 12 mph lifts the one-rider figure to 133 miles; a steady 8% climb at 10 mph on the throttle brings it down to about 11.

Three steps turn your ride into miles:

1. Find your pace and your effort in the first two tables, and with a passenger aboard, the load table.
2. Add the climbing: 159 to 203 Wh per 1,000 feet at 10 mph on 4 to 10% grades on the throttle, or 144 to 184 Wh with easy pedaling (the hills table).
3. Correct for the air temperature, then plan on 85% of the pack.

A row is one steady ride. Four sources feed it: Addmotor's figures, a comparable motor's published data, drum measurements of ten fat tires and a cycling-power model validated on an open road; the formula subsection carries one ride through by hand.

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

Speed decides most of it: 83 miles at 8 mph, 67 at 12 and 39 at 20. As you go faster the air takes a bigger share of the work, rising with the cube of speed.

One 180 lb rider on the throttle alone, level pavement, air at 77 °F, the bike at 112.2 lb with its pack. The 15% column holds back the top of Addmotor's "10%-15%" recharge advice.

Your legs add to every row. Easy pedaling is 75 W here and steady pedaling 150 W; with the motor off, those efforts alone would carry one 180 lb rider on this bike at about 8.5 and 12.7 mph on the flat.

One 180 lb rider, level pavement. "Legs alone" means 150 W from you holds that pace without the motor. The 133 and 156-mile cells rest on the motor's losses at light load, the least-checked part of the model (Limitations item 6).

The assist level only divides the work between you and the motor; the speed and your own effort decide the miles. With a torque sensor, a low level and an easy, even push put you in the middle column.

Does shifting gears save battery?

Only by way of your legs. The motor turns the rear wheel apart from your chain, so at a given speed and grade the pack's draw falls only as your effort rises:

Pack watt-hours per mile for one 180 lb rider in 77 °F air. On the flat at 12 mph, 150 W of steady pedaling holds the pace and the motor draws nothing.

Shimano's Altus 7-speed runs a 14 to 28-tooth cassette. Choose the gear that keeps your cadence comfortable, and shift down two or three before you stop, so the next start shares the push between your legs and the motor.

What does a climb cost the pack?

On 4 to 10% grades, a 1,000-foot climb at 10 mph costs 159 to 203 Wh more than the same miles on the flat with the throttle doing the work, or 144 to 184 Wh with easy pedaling. Lifting rider and bike takes 54 to 69% of the throttle figure; the rest turns to heat in the motor and the pack.

A 180 lb rider on the 112.2 lb bike makes 292.2 lb to lift, and 1,000 feet of height takes about 110 Wh at the wheel. Up 8% at 10 mph on the throttle, the pack spends 186 Wh per 1,000 feet, so all 960 Wh would lift that load about 5,100 feet with nothing left for the flat.

Every row at 10 mph with one 180 lb rider; the last column adds 75 W of easy pedaling. The model returns nothing for the way back down, which keeps these figures on the careful side.

With two aboard, a grade costs speed before it costs miles. The motor's torque sets the fastest steady speed it holds on a grade, and more weight lowers it:

The fastest steady speed the model's motor holds on each grade with one 180 lb rider or two riders totaling Addmotor's 300 lb payload, on the throttle except the last column. Steady state only: no momentum carried into the grade, and the motor's 80 N·m cap from Addmotor's image.

Plan a hilly day as flat miles plus climbing. Twenty level miles at 12 mph on the throttle use about 288 Wh, and 1,000 feet of 8% grade about 186 Wh: the day needs about 474 Wh, 58% of the 816 Wh in 85% of the pack.

How far does a passenger take the range?

A second rider costs about a fifth of the miles on the flat, and holds the climb to a lower speed. Weight adds to the tires' work and the grade's but not the air's, so the gap between one rider and two widens as the road tilts up.

The load column counts both riders and everything they wear and carry; the model adds the bike's 112.2 lb, and every cell is on the throttle. At 300 lb, holding 10 mph up 8% needs more torque than the model's motor has; the climbing table gives the 9.7 mph it holds.

From one 180 lb rider to two totaling Addmotor's 300 lb, the 12 mph ride falls from 67 miles to 55 and the 15 mph ride from 55 to 47. That 300 lb is the whole budget, so two adults of 150 lb each fill it with nothing left for bags.

Addmotor prints the weight two ways: "99 lbs (excluding battery)" in the Technical tab, which with the 13.2 lb pack comes to 112.2 lb, and "Bike Weight: 83.8 lbs" in its post of April 21, 2025, which does not say whether the pack is in. Both weights run through the model:

One 180 lb rider on the throttle. Every other table uses 112.2 lb, the Technical tab's 99 lb plus Addmotor's 13.2 lb for the pack.

How much range does cold weather take away?

Expect about a fifth less at freezing. A 12 mph throttle ride good for 67 miles in 77 °F air comes to about 53 miles at 32 °F and about 48 at 14 °F.

One 180 lb rider, level ground, the cells at the air's temperature. The middle figure in each row comes from the LG HG2 cell McMaster University measured at a 0.5C discharge, with rows between interpolated; Addmotor names Samsung as its cell maker, so the brackets come from Samsung data sheets.

Each bracket runs from the lowest capacity a Samsung data sheet gives at that temperature, at one to four capacities an hour (25R and 30Q at 32 °F, 35E at 14 °F), up to the most energy Casado and colleagues recorded at a gentler rate.

The cold costs in three places at once: the cells give back less, the air thickens by the U.S. Standard Atmosphere's gas law, and the tires stiffen. The model raises rolling resistance 0.5% for each °F below 77 °F, between Rothhämel's fit for a 42 mm tire and Bicycle Rolling Resistance's road-tire average, and holds it at its 41 °F value below that.

Bring the pack inside to charge it. Addmotor's maintenance guide says to charge "at room temperature (between 10 and 25 degrees Celsius)", which is 50 to 77 °F.

Does the tire or the riding position change the range?

On the flat, the tire changes more than the posture. On Bicycle Rolling Resistance's drum at 12 psi, ten 26 × 4.00 fat tires drew between 23.2 and 42.1 W. The Soletan rides 20 × 4.0 Kenda GIGAS tires, so the model takes the ten tires' median, a coefficient of 0.0105, with the lowest and highest as brackets.

Full-charge miles for one 180 lb rider on level ground. The high bracket is Kenda's Juggernaut Pro, measured at 0.01262 on its own page.

Gravel, grass and sand sit outside these pavement tables; send us your route and we will price its paved miles and climbs. For the air, Tengattini and Bigazzi measured a 0.640 m² drag area across 37 upright cruiser riders, the figure used here; their 0.603 m² for mountain-bike riders gains about two miles at 15 mph, 55 to 57. A passenger seated behind you adds frontal area the model does not count (Limitations item 11).

Addmotor's 105 miles, as a steady ride

Addmotor's 105 miles is a pedaling figure, and the model agrees once your legs join in. The Technical tab prints "Up to 105 miles with PAS 1 mode (8 MPH)", and the stat strip "48V*20Ah per Charge (PAS1) 105 Miles": a ride on the lowest assist level, at 8 mph, with you pedaling.

One 180 lb rider on level ground. At 8 mph the throttle alone gives 83 miles; about 16 W from your legs, well under easy pedaling, closes the gap to 105, and 75 W would carry 8 mph with no motor at all.

Read that way, Addmotor's 105 miles is a gentle, pedaled ride on assist level 1. At a brisker pace the same 960 Wh reaches 105 miles only with your legs in the work: about 13.4 mph at 75 W of easy pedaling, or 16.7 mph at 150 W.

To spare the cells, ride inside the 20–80% band. The band holds 60% of the pack, 576 Wh; Addmotor's maintenance guide says "keep your battery charge between 20% and 80% for the best lifespan", and its battery-health post advises recharging at "10%-15%" left:

Miles inside the band for one 180 lb rider on level ground. At 8 mph, 75 W from your legs holds about 8.5 mph by itself, so the motor adds nothing: "legs alone".

The formula behind the range tables

The power the rear wheel needs at a steady speed in still air comes from the model Martin and colleagues validated on an open road in 1998:

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

Here P is the power at the wheel and v the road speed; m is the combined mass of the bike, the riders and their load, g is gravity and θ the slope's angle; Crr is the tires' rolling resistance, ρ the density of the air and CdA the rider's drag area. Three stages sit between the wheel and the pack:

1. Your pedaling reaches the wheel through the chain at 97.7% efficiency, the figure Martin and colleagues measured, and the motor supplies the rest.
2. The motor takes the curve of a comparable motor whose figures are published: for its RM G0H0, Bafang's 2021 OEM workbook lists 510 rpm unloaded and 426 rpm at rated load at 48 V, with "≥ 80" percent efficiency. Held at Addmotor's 48 V and 750 W, the curve gets an unloaded speed of 21.8 mph in the model, the speed at which one 180 lb rider on the throttle just reaches Addmotor's 20 mph on the flat.
3. The pack loses a small share as heat, at the efficiency Arango, Lopez and Ceren measured on a 48 V pack.

Battery watts divided by mph give watt-hours per mile, and the miles follow: 960 Wh × the share usable at that temperature ÷ watt-hours per mile.

One ride, worked by hand from the wheel to the pack: one 180 lb rider, 12 mph on the throttle, level pavement. Rider and bike weigh 132.5 kg together; the wheel needs 132.0 W, rolling resistance taking 73.5 W of it and the air 58.5 W.

At 12 mph the 24-inch rear wheel turns 168 times a minute. Fitted to Bafang's figures, the motor model carries a torque constant of 1.50 N·m per amp, a 0.405 Ω winding and a 0.83 A no-load current; this ride asks it for 7.5 N·m on 5.8 A, at 79% efficiency, a point under the rated 80% because the load is light.

Adding the pack's internal losses, the cells deliver 172.7 W; at 12 mph that is 14.39 Wh a mile, and 960 ÷ 14.39 is about 66.7 miles, 56.7 with the 15% reserve held back.

Two published benchmarks, reproduced before any figure was computed:

Before the tables ran, the model reproduced Appendix I of Martin and colleagues (8.36 m/s, a 90 kg system, a 0.3% grade) and the rated point of Bafang's RM G0H0.

No measured ride on the Soletan with the rider's weight and speed stated was found to set beside the model. The ten answered questions on Addmotor's board for the bike and the 45 Addmotor posts naming it were read on October 2, 2026; none of their range figures states a speed and a rider weight together.

Carrying two: a 300 lb budget on one long seat

The 300 lb counts both riders, what they wear and what they carry. The Technical tab prints "Payload: 300 lbs", the stat strip "Payload Capacity 300 LBS", and Addmotor's posts from 2023 on print the same figure.

That budget is the number to plan around with a passenger. Two adults of 150 lb each fill it; a 190 lb rider leaves 110 lb for a passenger and any bag. Add both riders' weights before the first ride two-up, and keep the sum at or under 300 lb.

The seat is 23.5 inches long and 8.5 inches wide on Addmotor's size drawing, and the passenger's feet go on the rear pegs Addmotor's January 16, 2025 answer confirms. Addmotor's page also offers a "Backrest For M-66X" and a "Rear Rack For M-66X" as add-ons; email us and we will check whether we can supply either with your order.

The passenger section quotes what each state's code says about a second rider on a bicycle, and the climbing table shows what a full 300 lb does to your speed on a grade.

Mechanical discs, four-finger levers, turn signals and lights

Tektro Aries mechanical discs at both ends, on 180 mm rotors, with motor cutoffs in the levers. The Performance tab lists "Tektro Aries Mechanical Disc with 180 mm Rotors, Tektro Four-Finger Levers with Rubberized Edge and Motor Inhibitors": pull a lever and the motor stops pushing.

With a passenger aboard, brake earlier. Two riders at 300 lb ask more of a cable-pulled disc than one does, so begin slowing sooner, keep both hands on the levers, and practice a few stops two-up in an empty lot before the first ride in traffic.

The light set is part of the price. Addmotor's light image labels the taillight's functions "Danger Light", "Smart Brake Signals", "Flashing Light", "Left Turn Signals" and "Right Turn Signals", and a horn and a bell sit on the bar beside a front headlight.

A full-suspension frame and 20 × 4.0 fat tires

A fork at the front and a coil shock at the back. Addmotor's key-features image names a "Full-Suspension System", and its studio photographs show a fork with ADDSHOX lettering and a coil-over shock between the swingarm and the seat frame.

The front fork and rear shock highlighted in Addmotor's image.

With a shock under the seat as well as the fork, the rear rider rides on the suspension too, which a rigid rear end would not give a passenger. Addmotor's banner adds "all-terrain capability" to the 105-mile figure; the range tables price pavement only.

The Performance tab names "Kenda GIGAS Puncture-resistant 20" X 4.0" Fat Tires", on wheels Addmotor's tire image calls "One-Piece Alloy Wheels". Asked about black tires for a black Soletan, Addmotor answered on June 25, 2023 with a link to "the 20" X 4.0" tires for SOLETAN Ebike" sold on its site.

About 112 pounds as ridden, 72 inches long

Plan for about 112 lb, 72 inches of length and a 30-inch bar. The Technical tab prints 99 lb without the pack, and the pack itself is 13.2 lb in Addmotor's answer on its page; Addmotor's April 21, 2025 post prints 83.8 lb, a figure the weight table runs as a check.

Measure the door and the parking spot before delivery. A bike 72 inches long needs that much floor along a wall, and a door its 30-inch bars pass through. A ground-level spot spares you lifting 112 lb.

The Mercer fit test

Every review we publish puts the same seven people, the Mercers, on its bike, and here each one sits on the Soletan's 32.5-inch seat. A verdict reads a figure from Addmotor's Size & Fit tab, its 5'2" to 6'2" window, the seat, the 17-inch standover and the 300 lb payload, or the fit tables computed on them.

All five adults fall inside Addmotor's window, and for every one of them the seat sits below the formula's height. The taller the rider, the surer the footing at a stop and the more bent the knee at the bottom of the stroke; for long, hard pedaling, the verdict names a bike on our shelf whose seat rises.

Has it been recalled?

No. On October 2, 2026, no recall in the Consumer Product Safety Commission's recall data named Addmotor, the Soletan or the M-66X.

We ran the recall title, product name and manufacturer fields for Addmotor, ADDMOTOR, Add Motor, Addmotor Tech, Motan and Addrider, and for 19 Addmotor model families, Soletan among them. Then we read every field of a 623-record corpus of bicycle, e-bike, battery and scooter recalls for the brand, those families and the model code, written M-66X, M66X or M 66X.

The same run returned 1 recall for Ancheer, 54 for Specialized and 24 for Trek, so the search does find recalls where they exist.

Class and road rules: where a 750 W banana-seat bike lands

Whether the Soletan counts as an e-bike where you live turns on your state's words, and in Pennsylvania on its weight. Addmotor's page prints the three figures every definition below draws a line at: 750 W, a throttle and 20 mph.

The federal text, 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.)", with a motor-only top speed "less than 20 mph" for a 170-pound rider on a paved level surface.

Read October 2, 2026: the left column from § 2085(b), the right from Addmotor's Technical and Performance tabs and its stat strip.

Both the watts and the speed land on a line the federal text draws at "less than". Addmotor's 20 mph is its own top-speed figure rather than a run of the statute's motor-only test, so the published numbers cannot settle where the Soletan falls on that test.

California writes its line to include 750 W: Vehicle Code § 312.5(a) takes in "an electric motor that does not exceed 750 watts of power".

We screened the 50 states and DC on watt wording, throttle rule, top speed, wheel count and Pennsylvania's weight limit, and on October 2, 2026, Addmotor's published figures for the Soletan sit inside 28 jurisdictions' e-bike definitions and outside 21. Alaska and Kentucky define no e-bike.

Each definition screened on October 2, 2026, as our state law atlas records it. In 19 of the 21, the motor must be "less than" or "fewer than" 750 watts, and 750 W is neither. New Jersey's line falls on the throttle. Pennsylvania's definition is written for "A vehicle weighing not more than 100 pounds".

Pennsylvania is the row that moves with the weight. Addmotor's Technical tab gives 99 lb without the battery and its April 21, 2025 post 83.8 lb, and a screen run at 83.8 lb puts Pennsylvania inside, the only row to change.

As delivered, with its 13.2 lb pack, the Soletan comes to about 112 lb, so this page counts Pennsylvania outside; if you ride there, write to us before you order and we will ask Addmotor for the weight of your build in writing.

The screen does not settle two inside rows. South Carolina's definition asks for "a top motor-powered speed of less than twenty miles an hour when operated by a rider weighing one hundred seventy pounds", the federal test in its own words, and Connecticut's "not more than seven hundred fifty watts" has applied since October 1, 2026 under Public Act 26-24 § 26.

From December 1, 2026, North Carolina sorts e-bikes into three classes. Session Law 2026-46 keeps "no more than 750 watts", and a class 2 motor there "may propel the bicycle without pedaling but ceases to assist once the bicycle reaches a speed of 20 miles per hour", so the Soletan's row stays where it is.

Outside a state's e-bike definition, the Soletan is still a vehicle in that state, and the class the code puts it in sets the licensing, registration and riding rules that apply. Our 50-state e-bike law atlas has each state's page, California's among them.

Riding two-up or with a child: what your state's code says

Of the 28 jurisdictions whose definitions take in the Soletan, 25 cap riders at what the bicycle is designed or equipped to carry or ask for a seat for the passenger, and ten write in how a young child may ride. We read each passenger rule in the jurisdiction's own text and checked every quote against it on October 2, 2026.

Addmotor's description is the starting point: a 23.5-inch seat, the rear footpegs it confirmed on January 16, 2025, and a banner selling the Soletan as "the full-suspension e-bike for two". Most of the codes below measure a passenger against what the bicycle is built to carry; three ask for a seat instead.

Each rule read in the jurisdiction's official text, on October 2, 2026 or from a copy deposited between August and October 1, 2026; Georgia's and New Mexico's in a FindLaw copy of the code. New Mexico brings an e-bike inside "bicycle" for its child helmet act, and the sections read leave open whether its passenger rule reaches one; the row gives the rule as written.

In California, Massachusetts and Maryland, the words to read are about the seat. California's § 21204(b) seats a passenger "upon or astride a separate seat attached thereto"; Massachusetts's c. 85, § 11B(2)(i) "upon or astride a permanent and regular seat attached to the bicycle"; and Maryland's § 21-1203(b) asks that the bicycle be "designed for and equipped with a seat securely attached to it for each passenger".

A long seat that two people share can be read either way under those words. It is attached to the frame and holds two riders, which reads as a seat for each; "separate" and "for each passenger" can also be read as a seat the passenger has alone.

Where one of these three is home, ask the state's motor vehicle agency how it reads a shared seat, or look at the Greattan L, whose passenger has a seat, backrest and belt of their own.

The District of Columbia counts riders against what the vehicle "is equipped to carry" (18 DCMR § 1201.5), and its definition of a motorized bicycle in § 50-2201.02(11A) begins with "A post mounted seat or saddle for each person that the device is designed and equipped to carry"; the Soletan's seat sits on the frame with no post.

Indiana's IC 9-21-11-3 wants a passenger "seated upon a firmly attached and regular seat on the bicycle", and Oregon treats too many riders as "a Class D traffic violation" under ORS 814.460, for which ORS 153.019 sets a presumptive fine of "$115 for a Class D violation" before any surcharge.

Ten of the 28 write in a young child, most of them by naming a seat, a carrier or a sling. The wording is each state's own:

From the census of October 2, 2026. Connecticut's subsection reaches a rider "upon a roadway, path or part of roadway set aside for exclusive use of bicycles, electric bicycles or electric foot scooters", and its child exception does not name an electric bicycle.

North Carolina's § 20-171.9 asks for a helmet under 16 and a restraining seat for a passenger under 40 lb or 40 inches, on a "Bicycle" that § 20-171.8 defines as "a human-powered vehicle"; whether those rules reach an e-bike is open, and following them covers you either way.

Trails and public land: who decides where it rides

Once you leave the pavement, the land manager's rule applies, not the state's road code. Federal land has two systems: the Bureau of Land Management defines an e-bike at 750 W, and the Forest Service sets e-bike access ranger district by ranger district.

The BLM's definition in 43 CFR 8340.0-5 is "a two- or three-wheeled cycle with fully operable pedals and an electric motor of not more than 750 watts (1 h.p.)", so Addmotor's 750 W sits inside it. A field office may let e-bikes ride where bicycles do, on the condition that "the motor is not exclusively propelling the e-bike for an extended period of time".

A long stretch on the throttle is the case that condition is written about. Where a field office has made no such decision, or the condition is not met, 43 CFR 8341.1 limits off-road vehicles to land designated "open to off-road vehicle use".

On National Forest land, the Forest Service directives of March 31, 2022 manage "all classes of e-bikes as motor vehicles" (87 FR 41278). Where a ranger district has published a motor vehicle use map, 36 CFR 261.13 bars riding "other than in accordance with those designations".

Each row ends at the land manager's own document. Our public-land e-bike guide goes through each agency's rules in full.

Green flags / Red flags

Green flags

• A 23.5-inch banana seat with rear footpegs, built and sold for two riders.
• Front and rear suspension, a fork and a coil shock under the seat, on 20 × 4.0 Kenda fat tires.
• A 17-inch standover that every rider in the survey from 5'2" to 6'2" clears, with a footboard to step onto.
• A seat low enough to reach the ground: 90 of every 100 riders at 5'10" sit flat-footed.
• A 750 W rear-mounted motor with a torque sensor and a twist throttle, 80 N·m in Addmotor's figures.
• About 55 miles at 12 mph on the throttle with two riders at 300 lb, 67 with one 180 lb rider, on level pavement.
• Turn signals, a brake light and a horn as standard, with motor cutoffs in the brake levers.
• Bars that come back to you: every rider in the window reaches the grips sitting upright.

Red flags

Each one is about fit: who the Soletan is wrong for, and where to go instead.

• Wrong if you want a seat you can raise for long, hard pedaling. The Garootan M-81 has a 33 to 42-inch seat post and a rack built into its frame, at $1,099 on our store.
• Wrong if you want three wheels under the same 23.5-inch seat. The Soletri II carries a banana seat of that length on a trike with full suspension, at $2,699.
• Wrong if your passenger needs a seat with a backrest, armrests and a belt. The Greattan L gives the second rider a seat of their own, from $3,699.
• Wrong if two riders and their bags come to more than 300 lb. Email us both weights, and our reply will name a bike or trike on our shelf rated for the sum.
• Wrong if you climb 8% grades two-up and want to hold 12 mph. At 300 lb, the model holds 9.7 mph on 8% and 8.1 on 10%; send us your steepest climb and both weights, and we will price the ride before you order.
• Wrong if you live in one of the 21 states whose words leave the Soletan outside their e-bike definition. Tell us your state, and our reply will quote its rule and name a bike on our shelf that its definition takes in.

Buy it if / Buy something else if

Buy it if you want one machine for two riders: a 23.5-inch banana seat with rear footpegs, front and rear suspension, a torque sensor and a twist throttle, a 17-inch step and a seat low enough to reach the ground at a stop, with about 55 miles at 12 mph on the throttle for two riders at 300 lb.

It asks for riders inside Addmotor's window of 5'2" to 6'2", a combined load at or under 300 lb, a state whose e-bike definition takes in the Soletan and, before anyone rides behind you, a read of that state's passenger rule.

For $1,799 you get a 750 W rear-mounted motor with 80 N·m in Addmotor's figures and a 960 Wh Samsung pack, mechanical discs on 180 mm rotors, seven Shimano gears, turn signals and fenders. On Shop Pay's 12-month sample plan from our listing, that is $162.37 a month at 15% APR, $1,948.44 in all.

Buy something else if you want to pedal hard on a seat set to your leg, where the Garootan M-81 is $1,099; if you want three wheels under the same seat, where the Soletri II is $2,699; or if your passenger needs a seat with a backrest and a belt, where the Greattan L is from $3,699.

Our Addmotor brand profile places the Soletan among the other Addmotors we sell, and our e-bike reviews hub lists every review we have published.

Before you buy: the checklist

Ten checks before you spend $1,799; the first three settle who rides, who rides along and where.

1. Look up your state in the class table, then its passenger and child rules in the passenger tables and its page in our law atlas.
2. Check each trail and park on your list with the agency that manages it.
3. Weigh both riders in what they wear, add the bags, and keep the sum at or under 300 lb.
4. Measure your inseam and find your row in the seat table and the flat-footed figures beneath it.
5. Ride your passenger's first trips on quiet streets after a few starts and stops in an empty lot with both of you aboard.
6. Price your longest ride in the range tables, with the climbing, and keep 15% of the pack in reserve.
7. Choose a charging spot indoors, at 50 to 77 °F.
8. Measure the door and the parking spot: 72 inches long, 30 across the bars.
9. Plan the lock for a 72-inch frame and the pack.
10. Pick your colorway in the buying table: Black, Orange and Pearl White order directly, and Yellow starts with an email.

Buying it from us

Why buy the Soletan M-66X from Redtail

On October 3, 2026, our listing priced the Soletan M-66X at $1,799 in every colorway, with $2,599 shown as the regular price, and Addmotor's own page listed the same $1,799 that day.

Three colorways have a button of their own. On October 2, 2026, Addmotor's page listed Yellow as a preorder, so for Yellow, email us first and we will confirm a date with Addmotor; Purple is sold out on our store.

Each button puts that colorway in your cart at the price our store listed on October 3, 2026.

Orange, the bike on the cover, from the front quarter.

Change your mind, and our refund policy takes back a bike still sealed in its factory packaging if you ask within 72 hours of delivery, less a 15% restocking fee and the return shipping; canceling an order carries a 3% transaction fee. Settling the fit, the load and your state's passenger rule with us before the box leaves is the surer course.

Frequently asked questions

How far can the Addmotor Soletan M-66X go on one charge?

Addmotor prints "Up to 105 miles with PAS 1 mode (8 MPH)" in the Technical tab, a pedaling figure. On the throttle over level pavement, the model gives one 180 lb rider about 67 miles at 12 mph and two riders at 300 lb about 55; each 1,000 feet of climbing at 10 mph costs one rider another 159 to 203 Wh (the range tables).

Can two adults ride the Soletan M-66X?

Addmotor builds it for two: a 23.5-inch seat, rear footpegs and a 300 lb payload that covers both riders and their bags. Whether your state allows a second rider is its own call: 25 of the 28 jurisdictions whose e-bike definitions take in the Soletan cap riders at what the bicycle is built to carry or ask for a seat (the passenger section).

How much weight can the Soletan M-66X carry?

300 lb in all, in Addmotor's Technical tab and stat strip, counting both riders, what they wear and what they carry. A 200 lb rider leaves 100 lb for a passenger and bags, and two riders at 300 lb hold 9.7 mph up an 8% grade on the throttle (carrying two).

How much does the Addmotor Soletan weigh?

About 112 lb with the battery: the Technical tab prints 99 lb without it, and Addmotor's battery page gives the pack as 13.2 lb. Addmotor's April 21, 2025 post prints 83.8 lb, and the range tables run on both (weight and size).

What height rider fits the Soletan M-66X?

Addmotor sizes it for riders 5'2" to 6'2". The seat is fixed at 32.5 inches, which meets the 109% pedaling formula only for a 26.2-inch inseam, shorter than the leg of any surveyed rider in that window; in return, seated, 20 of 100 riders at 5'6" and 90 of 100 at 5'10" put both feet flat (the fit section).

Can you put a child seat on the Soletan?

None comes with it, and the specification lists no rack to mount one on; Addmotor's page offers a rear rack for the M-66X as an add-on, which we can check on for your order. Before a child rides along, read your state's words: ten of the 28 jurisdictions inside the e-bike definition write in a young child (the passenger section).

How fast does the Addmotor Soletan go?

Addmotor's stat strip prints "Top Speed 20 MPH". With two riders at 300 lb on the throttle, the model holds 15.2 mph up a 4% grade and 9.7 mph up 8% (the climbing table).

Does the Soletan M-66X have a throttle?

Yes. Asked about it, Addmotor answered on October 19, 2023 "twist throttle", and every range table prints the miles on the throttle alone. When you pedal, the torque sensor adds more help the harder you press (the motor).

What brakes does the Soletan M-66X have?

Mechanical discs at both wheels: the Performance tab lists "Tektro Aries Mechanical Disc with 180 mm Rotors", with four-finger levers that cut the motor. The taillight adds brake and turn signals (brakes and lights).

Is the Soletan M-66X full suspension?

Yes: Addmotor's key-features image names a "Full-Suspension System", a fork at the front and a coil shock under the seat, and the page lists 20 × 4.0 Kenda fat tires on one-piece alloy wheels (suspension and tires).

What is a banana seat bike?

One with a long, flat seat in place of a saddle on a post. The Soletan's is 23.5 by 8.5 inches on Addmotor's size drawing, fixed at 32.5 inches off the ground, with footpegs behind it for a second rider (the banana seat).

Is the Soletan an e-bike or a moped?

Addmotor's page calls it a "Full Suspension Electric Moped Bike For Adults", which describes its look; it has pedals, a chain and seven gears. Your state decides how it is classed: on October 2, 2026, 28 jurisdictions' e-bike definitions take in Addmotor's figures and 21 leave it out (the class table).

Do you need a license to ride the Soletan M-66X?

Your state's code decides, and the answer follows its class. Where the e-bike definition takes the Soletan in, it rides under that state's e-bike rules; where it does not, the class the code puts it in sets licensing and registration (the class table). Write to us with your state, and our reply will quote what its code asks.

Is the Addmotor Soletan M-66X street legal, and what class is it?

Your state's words decide. Addmotor's 750 W, throttle and 20 mph sit inside 28 jurisdictions' e-bike definitions on October 2, 2026, California's "does not exceed 750 watts" among them, and outside 21. Some states sort e-bikes by class: from December 1, 2026, North Carolina's class 2 motor "may propel the bicycle without pedaling but ceases to assist once the bicycle reaches a speed of 20 miles per hour" (the class table).

Is the Soletan M-66X worth it?

For riders 5'2" to 6'2" who want one long seat for two, full suspension, a torque sensor and a seat low enough to reach the ground, it brings those together for $1,799, or $162.37 a month for 12 months at 15% APR on Shop Pay's sample plan. A rider who mostly pedals hard and alone is better matched to the Garootan M-81 and its 33 to 42-inch post (the verdict).

What warranty does the Soletan M-66X have?

Bought from us, a fault comes to us first: we open the claim with Addmotor and stay with it until the bike is put right. For Addmotor's written terms on your order, ask us before checkout, and we will send them to you in writing.

Limitations of this review

Twenty points this review cannot settle, set out so you can weigh them.

1. We sell this bike. Read the red flags as carefully as the green ones.
2. This review is specification-verified. Its figures come from Addmotor's published documents, statutes, our own store record, the published research the range and fit sections cite, or arithmetic shown on this page.
3. Each range figure is one steady ride: one speed, one grade, still air and no stops. Starts from rest with two aboard, stops, headwind and soft ground all cost more.
4. Bafang's published figures stand in for Addmotor's motor. Addmotor gives its rating, peak and torque, but not its motor speeds or efficiency.
5. Addmotor's 1,300 W peak does not enter the model, which runs on the rated 750 W curve with the image's 80 N·m as its torque cap; the climbing table is that curve's answer.
6. At light motor load the model has no measured check. Where your legs supply the larger share of the power, as in the pedaling columns, the figures rest on motor losses not checked against a published motor map.
7. Addmotor prints the weight two ways: 99 lb without the pack in the Technical tab, which with the 13.2 lb pack comes to the 112.2 lb the tables use, and 83.8 lb in its April 21, 2025 post, which does not say whether the pack is included. The weight table runs both, and Pennsylvania's row in the class table turns on which applies.
8. No measured range day on the Soletan was found. The documents read are named at the end of the formula section.
9. Every figure assumes the whole pack is usable. The documents read here do not say how much the battery management releases; on one measured pedelec, researchers at KIT found 75% in use during a standard range test.
10. The tire coefficient is the median of ten 26 × 4.00 fat tires at 12 psi, a larger size than the Soletan's 20 × 4.0, and the tire table brackets it.
11. A passenger's frontal area is not in the model. The drag area is one upright rider's, so with a second rider behind you the figures at higher speeds are upper bounds; at 12 mph and below, rolling resistance and the grade outweigh the air.
12. The cold figures rest on one cell's laboratory data. Addmotor names Samsung cells without a model number, so the central line uses McMaster University's LG HG2 cell, bracketed by Samsung's sheets and other published data.
13. The seat height is Addmotor's single printed figure, and the sitting point, crank length and crank-axle height are measured on its size drawing, each with a bracket printed in the fit inputs.
14. Addmotor's drawing holds to one scale within limits. Five of six printed dimensions agree within 3.5% measured from the tread line and three of six from the arrows' baseline; the tire measures 6.3% under its nominal size, and the grip height is taken from Addmotor's 43-inch label.
15. 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. The flat-footed counts set a barefoot inseam against the seat top, so shoes add the thickness of their soles; your own inseam decides your row.
16. The hand loads assume a relaxed back and put the arms' whole weight on the grips, so each figure is an upper bound, with the grip position bracketed by the reads taken on Addmotor's drawing.
17. The battery's certification is as Addmotor describes it: "UL-certified" in the Technical tab and "UL 2271" in the stat strip. No certificate number was read; where a building or an insurer asks for one, email us and we will request Addmotor's documents in writing.
18. The class and passenger tables read each state's words as our atlas and the October 2, 2026 census record them. A state can change its words, as Connecticut did on October 1, 2026 and North Carolina will on December 1; Georgia's and New Mexico's passenger rules were read in a FindLaw copy of the code.
19. Colorways, prices and stock were read on October 3, 2026, and each can change, as can the Shop Pay terms and Addmotor's preorder dates. That day Purple was sold out on our store and Yellow a preorder at Addmotor.
20. Addmotor's records name the tire two ways. The Performance tab lists Kenda GIGAS tires, and the sidewalls in Addmotor's Orange studio photograph carry Kenda's KRUSADE name; email us and we will confirm which ships.

The bottom line

At $1,799, the Soletan M-66X puts a 750 W rear-mounted motor, a torque sensor, a twist throttle and a 960 Wh Samsung pack under a 23.5-inch banana seat with rear footpegs, on a full-suspension frame with a 17-inch step, mechanical discs, turn signals and a 300 lb payload for both riders together.

The model gives one 180 lb rider about 67 miles at 12 mph on the throttle over level pavement and two riders at 300 lb about 55; climbing at 10 mph costs one rider 159 to 203 Wh per 1,000 feet.

The right owners are one or two riders inside Addmotor's 5'2" to 6'2" window, together at or under 300 lb, who value their feet on the ground at a stop over a seat set for long pedaling, and who live where the state's e-bike definition takes in the Soletan, with its passenger rule read before the first ride two-up.

On Shop Pay's 12-month sample plan the Soletan comes to $162.37 a month at 15% APR.

Before checkout, settle three things with us: where the 32.5-inch seat sits for each rider's leg, how far your route runs two-up, and what your state says about the second rider. Send both riders' heights and weights and your state, and one reply covers all three.
