Folding step-through e-bike · 750 W rear geared hub motor · torque sensor and a half-twist throttle · 48 V 20 Ah pack, 960 Wh, inside the frame · 20 × 4.0 tires on a 100 mm fork · hydraulic disc brakes with 180 mm rotors · 300 lb or 280 lb payload, as Addmotor prints both · 81.6 lb · $1,499 on October 12, 2026 · verified October 12, 2026

Quick Answer — Addmotor's Foldtan M-160 is a $1,499 folding step-through e-bike with a 750 W rear hub motor, a torque sensor, a 960 Wh pack inside the frame and 20 × 4.0 tires, sized for riders 5'2" to 6'3". On the throttle alone at a steady 12 mph over level pavement, a 180 lb rider computes to about 71 miles.

Check three things before you pick a color: the folded box against your trunk or closet, 34.1 × 20.9 × 28.3 inches (the fold); your barefoot inseam against the 37.8-inch top seat setting (fit); and whether your state's wording takes in a 750 W, 20 mph bike with a throttle (class).

How we verified this Addmotor M160 review

The figures below were read on October 12, 2026 from Addmotor's own M-160 documents: the product page with its stat strip, feature panels, specification list and Measurement list, the numbered measurement drawing, the question board, Addmotor's videos of the bike, and the Addmotor posts that print M-160 figures. Our own store supplied the price, the colors, the stock and the checkout, read that same day.

Each number names where it came from as you read it: Addmotor, a statute or regulation, our store, a published study, or arithmetic printed beside it, and the range and fit models list their inputs under their tables. We carry the M-160, which is why the red flags get as much care as the green ones.

Addmotor's Foldtan M-160 specification

Addmotor's Measurement list numbers each dimension the way its drawing numbers its lines:

Addmotor's Specifications and Measurement lists as served on October 12, 2026; the 5-inch display, the Addshox name, the 40-lumen headlight, the taillight's functions and the horn's 108 decibels come from the page's feature panels. Both seat heights are measured from the ground up, the way lines 3 and 4 run on Addmotor's drawing.

A step-through folder with its battery inside the frame

The M-160 is one of Addmotor's two Foldtan folding e-bikes, hinged at the middle of a low step-through frame with its pack inside the down tube. Addmotor's debut post of July 7, 2023 introduced it in five colors and called the pack "hidden inside the bike frame".

You step over a 14.4-inch frame to a padded saddle on a quick-release post, and the bar ahead is Addmotor's U-shape: the debut post describes "a crossbar in the middle that connects the two sides", with the 5-inch display mounted on it. The same post says the saddle slides "forward and backward" on its rails as well as up and down.

Owners write about it in their own words. On Addmotor's page, a buyer's review of April 6, 2024 tells of switching from red to green to skip a wait and having "recieved it in 4 days"; on Reddit, an owner wrote on February 9, 2024: "It folds up pretty easily to tuck away in my garage, and I can put it in my trunk if I want to take it with us on a weekend trip."

How the M-160 folds, and how big it is folded

Folded, the M-160 measures 34.1 × 20.9 × 28.3 inches on Addmotor's Specifications list, about 11.7 cubic feet, and it still weighs 81.6 lb. The frame hinges at its middle so the front wheel swings back beside the rear one, and Addmotor's debut post puts the job at "within 10 seconds".

Addmotor's folding image: the M-160 folded on the left, and the fold in three steps on the right.

Addmotor's Measurement list gives the folded width as a range, 16.5 to 20.9 inches, so measure your opening against 20.9. The folded drawing below numbers the three sides, and the Specifications list repeats the box as "Folded Size 34.1"L x 20.9"W x 28.3"H".

Addmotor's folded drawing; line 1 is the 34.1-inch length, line 2 the 16.5 to 20.9-inch width and line 3 the 28.3-inch height.

Where it can go, in Addmotor's own words: "It can fold and fit in your RV, van or motorhome," says the feature copy, and asked on the question board whether the bike can travel, Addmotor answered on July 26, 2023: "You can put it in your car's trunk."

The pack can come out before a lift. Addmotor's answer of the same day explains how: "First you take off the protective cover of the battery. Then use the key to help you remove the battery." Weigh the pack once on a bathroom scale after delivery, and you will know what each lift saves.

Our folding e-bike guide sets folded boxes side by side; the M-160's 11.67 cubic feet was the smallest it found printed on a maker's product page.

Who the M-160 fits: 5'2" to 6'3" and a 14.4-inch step

Inside Addmotor's 5'2" to 6'3" window, the pedaling formula wants the saddle's top 32.2 to 39.9 inches from the pedal, shortest height to tallest. Addmotor's seat heights, 29.5 to 37.8 inches, are measured from the ground, so a barefoot inseam longer than about 34.7 inches asks the formula for more than the top setting gives, before the pedal's own height off the ground is counted.

Its rule sets the saddle at 109% of your inseam above the pedal axle, with the crank pointing straight down; Peveler and colleagues set it against two other methods in 2005. Without a published bracket height or crank length, every row below is a starting target that your tape measure confirms on the bike.

Get to your row in three steps:

1. Measure your inseam barefoot. Stand against a wall, press a hardcover book up between your legs as a saddle would sit, keep it level, and read the floor-to-spine distance.
2. Find your height in the saddle table, then in the ceiling table beneath it, which counts how many riders your height outgrow the top setting.
3. On the bike, turn one crank down in line with the seat tube and measure from the saddle's top to the center of the lower pedal; if the post is at its top before you reach your row, email us before your first ride.

Addmotor's measurement drawing, its eight lines named in the Measurement list. The formula subsection shows why the drawing cannot be measured as a ruler.

How high does my saddle go?

Look up your height; the row gives the distance from the top of the saddle down to the pedal axle. The third column applies 109% to that height's median inseam; the last two apply 106%, where the range reported by Ferrer-Roca and colleagues begins, and 110.4%, where their proposed range ends.

Each inseam band runs from the 5th to the 95th percentile of that height in the US Army's ANSUR II survey of 6,068 people, and each distance is worked from the band's median leg. Your measured inseam outranks the table: one more inch of leg wants 1.09 more inches of saddle.

Past a 34.68-inch barefoot inseam the top seat setting cannot reach the 109% distance, and past 35.66 inches it falls short of 106% as well. Addmotor's 37.8-inch maximum is all this needs, since the pedal at the bottom of its stroke stays above the ground:

Counted over the same survey's bodies at each height. Every count is a floor: Addmotor prints no pedal height above the ground, and adding one could only raise the count.

The window reaches higher than the saddle: from 5'11" up, more than a third of riders need more saddle than the 37.8-inch setting gives. At 5'11", at least 36 of every 100 riders fall short of the 109% distance, at 6'0" at least 61, and at 6'3", the window's top, at least 98, so a rider over 5'10" should hold a barefoot inseam against the ceiling table before ordering.

At the short end, 4 of every 100 riders at 5'2" cannot be shown to fit the lowest setting. Their 106% distance is under 29.5 inches, and whether the 29.5-inch minimum comes low enough depends on the pedal's height off the ground, which Addmotor does not print; that is 9 of the survey's 245 people at 5'2", and none from 5'3" up.

Can I step through it at a stop?

Yes. Barefoot, all the surveyed riders between 5'2" and 6'3" clear its 14.4-inch standover. Even the shortest legs in the window, the 5th percentile at 5'2", keep more than 13 inches between inseam and frame.

Each row sets that height's barefoot inseams, from the same survey, against the 14.4-inch standover in Addmotor's Measurement list; the middle column is the median leg.

Will I lean forward to reach the bars?

The lean is not computed for the M-160, so your arms on the bike are the measure. Addmotor's list gives a 20.1-inch reach, drawn as line 7 from the seat post to the head tube at saddle height, but no grip position, handlebar height or seat angle, and the drawing cannot fill them in because its lines disagree on scale (the formula subsection).

Two settings change how far you reach. The debut post says the saddle slides fore and aft on its rails, and the quick-release post sets its height; set the height first, ride a block, and slide the saddle forward if your elbows lock straight.

How much weight goes through my hands?

The hand load follows from the lean, so it is not computed either. For a sense of scale, the ten road racers Carahalios measured in 2015 on their brake hoods put 15% of their weight through the bars, on road bikes whose hoods sit far lower and farther forward than the M-160's raised U-shaped bar in Addmotor's images.

Soften the elbows and keep your chest up. Numb palms on a long ride are worth a pair of padded gloves: across 36 riders, Slane and colleagues measured 10 to 28% less pressure on the palm with them.

How do I set the saddle at home?

With the crank at the bottom, put your heel on the pedal and raise the saddle until that leg locks straight. Pedaling on the ball of the foot then leaves the knee slightly bent. In Peveler and colleagues' 2005 comparison, that heel method put 70% of 19 trained cyclists inside the 25 to 35 degree knee bend that the injury literature recommends.

The M-160's post is a quick-release, so the change takes a lever: the instruction in the debut post is to "pull open the quick-release lever". Close the lever firmly after each change, and if the post is already at its top while your heel-down knee still bends, you have found the rider the tall-rider flag is written for.

The fit arithmetic, step by step

Every saddle figure here is 1.09 times an inseam, from the pedal axle at its lowest to the top of the saddle. A 5'8" rider with that height's median inseam, 32.64 inches, gets 35.6 inches from the 109% rule; LeMond's rule, 88.3% of the inseam from the crank axle, gives the same leg 28.8 inches.

Because the two rules start from different points, the pedal and the crank axle, only a crank length could convert one into the other, so each figure is read against its own rule. The ceiling and floor need neither: 37.8 divided by 1.09 is 34.68 inches of inseam, 37.8 divided by 1.06 is 35.66, and 29.5 divided by 1.06 is 27.83.

Nothing is measured off Addmotor's drawing, because its lines disagree on scale. Whichever line sets the scale, no more than two others land within 3.5% of their printed figures:

Each cell is how far a line, read end to end on Addmotor's drawing and divided by its column's scale, lands from the figure the Measurement list prints for it; the dash marks the line that sets the scale. The two seat-height lines, two settings drawn over one saddle, and the diagonal seat tube are left out. The five lines read imply 10.3 to 11.2 pixels per inch.

A 750 W rear geared hub and a torque sensor

One 750 W motor in the rear wheel, a geared hub, answering a torque sensor at the crank. Addmotor's Specifications list names an "Addmotor 48V*750W Integrated Wheel Motor (Rear-Mounted Geared Hub)", and the feature copy promises assistance "that matches your efforts" with a claimed range gain of "20%-30%".

Addmotor's debut post puts numbers on the assist: the lowest level adds about half of your effort, the highest about three times it. In the post's words, on PAS1 "The system will increase your pedaling power by approximately 50%", and "if you ride in the highest PAS mode, the system can increase your power by about 300%".

The throttle on Addmotor's list is a "Variable Speed Control - 1/2 Twist Throttle", so the motor also pulls with your feet still, and the feature copy leaves the mix to the rider: "You decide how to ride." Seven gears sit on a "Cassette 14-28 Tooth", and the 5-inch EB 2.0 display shows battery use, mileage, speed, assist level and the motor's current wattage.

The range model caps the motor at 90 N·m, the published maximum of a comparable Bafang hub (the formula); the class section sets out how the states read a 750 W, 20 mph bike with a throttle.

A 960 Wh pack inside the frame

48 volts times 20 amp-hours is 960 watt-hours, carried inside the down tube. The stat strip reads "Samsung Battery 48V*20Ah" and the Specifications list "Rated For 1,000-1,500 Charge Cycles". The feature copy says the pack inside the tube "can be better protected against impact, water, and sunlight", and the debut post adds a "lower risk of theft".

Addmotor's battery image: the pack coming out of the down tube.

It comes out with the key. Asked whether the battery can be removed and charged, Addmotor answered on its board on July 26, 2023: "Yes, it's OK. First you take off the protective cover of the battery. Then use the key to help you remove the battery." The feature copy calls it a "Rechargeable and removable 20Ah battery".

Plan on most of a night for a full charge. Addmotor's list gives "Charging Time 8-10 Hours". Addmotor's April 21, 2025 roundup lists the M-160's pack as a "UL 2271 e-bike battery"; if your building or insurer wants the certificate itself, email us and we will ask Addmotor for it in writing.

Filling the pack costs about 18 cents. At 18.31 cents per kWh, the US residential average for July 2026 in the Energy Information Administration's Table 5.6.A, 960 Wh comes to about 18 cents before the charger's losses, and at 1,000 miles a year on the throttle at 12 mph, the pack draws about 13.6 kWh, which is about $2.49 a year.

Three figures from Addmotor's own pack-care advice:

• top up "when it has a 10%-15% charge left", in its battery-health post;
• for the longest life, "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)", which is 50 to 77 °F, per the same guide.

Range: how far a charge takes the M-160

On a full pack and the throttle alone over level pavement, a 180 lb rider goes about 80 miles at 10 mph, 71 at 12 and 41 at the 20 mph top speed; loaded to Addmotor's 300 lb, the 12 mph figure falls to about 57.

Pedal easily, about 75 W, and that 12 mph figure grows to about 147 miles; hold a 6% grade at 10 mph on the throttle instead, and a charge lasts about 16.

Plan a day on the M-160 in three steps:

1. In the first two tables, find the row for the speed you cruise at and the column for how hard you pedal.
2. Add the hills: each 1,000 feet of 4 to 8% grade costs 138 to 160 Wh more at 10 mph on the throttle (the hills table).
3. Adjust for your weight and load and the day's temperature, then plan on 85% of the pack.

Each row is one steady ride, built from Addmotor's figures, a comparable motor's published data, drum measurements of ten fat-bike tires and a cycling-power model validated on an open road; the formula subsection traces one ride from the tire patch to the cells.

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

Every step up in speed costs miles on the throttle, because air resistance climbs with the square of speed. A mile at 20 mph takes 23.6 Wh from the pack; a mile at 10 mph takes 12.0.

On the throttle alone with a 180 lb rider, over level pavement in 77 °F air. The right-hand column holds 15% of the pack back, the top of the "10%-15%" range at which Addmotor advises recharging.

Your legs stretch every row. The model counts 75 W as easy pedaling and 150 W as steady; with the motor off, those efforts would move a 180 lb rider on this 81.6 lb bike at about 9.0 and 13.0 mph on level ground, a guide to which column you can hold.

A full pack in every cell, 180 lb aboard on level pavement; "legs alone" means your 150 W holds that speed with the motor off. At 180 lb on level pavement, a cell past 100 miles depends mostly on your legs and on the motor's waste at light load, which is where the published data says least (Limitations item 5).

Settle on a pace, then on your effort: the assist level just splits the work between you and the motor.

Does shifting gears save battery?

Only through the work it lets your legs add. The hub motor turns the rear wheel directly, whatever gear the chain is in, so at a given speed and grade the pack spends less only when you push harder:

Watt-hours drawn from the pack per mile, 180 lb aboard, 77 °F air. At 12 mph up an 8% grade the motor holds the pace without help; the climbing table gives it 14.0 mph there.

Shift into a gear you can spin, because a gear too hard to turn adds nothing; on flat ground at 12 mph, a steady 150 W from you leaves the motor with nothing to do.

What does a climb cost the pack?

On a 4 to 8% grade at 10 mph on the throttle, each 1,000 feet of climbing costs 138 to 160 Wh more than the same miles on the flat. About 99 Wh of that is the bare work of raising 261.6 lb, rider 180 and bike 81.6, through 1,000 feet; the motor's and the pack's heat take the remainder.

Every row: 10 mph, 180 lb aboard. Descents return nothing here, so each figure is the climb alone.

On a steep street, torque sets your speed before the pack sets your distance. Every grade has a steady pace the motor can hold, and Addmotor's full 300 lb drags it down:

The fastest steady pace the model's motor keeps on each grade with 180 lb or the full 300 lb aboard, its torque capped at the comparable Bafang hub's 90 N·m, from a standing start up the grade.

Loaded to 300 lb, the M-160 still climbs a 12% street at about 7.5 mph on the throttle, and about 8.2 mph if you shift down and pedal easily.

Price a hilly day as two parts: the miles, as if flat, and the feet climbed. At 10 mph on the throttle, twenty flat miles take about 240 Wh; put 1,000 feet of 6% climbing inside those miles and the day comes to about 388 Wh, 48% of the 816 Wh you plan with at 85%.

Does rider weight affect the M-160's range?

Weight costs a little on the flat and a great deal uphill. It adds to rolling drag and to the pull of the slope while air drag stays put, so the steeper the road, the further a heavy load falls behind a light one.

You plus everything you carry, with the bike's own 81.6 lb added by the model; throttle only. The 300 lb row is the stat strip's payload, and the 280 lb row the Measurement list's.

From 180 lb to Addmotor's 300, the 12 mph throttle ride shrinks from about 71 miles to 57, and the 15 mph ride from 58 to 49.

How much range does cold weather take away?

About a fifth at freezing. The 12 mph throttle ride that lasts about 71 miles in 77 °F air lasts about 56 at 32 °F and about 51 at 14 °F.

Flat road, 180 lb aboard, with the pack cooled or warmed to the air around it. The central figures interpolate McMaster University's LG HG2 cell measurements at a 0.5C discharge, taken at 77, 50, 32 and 14 °F; the bracketed ranges draw on Samsung's cell data sheets and Casado and colleagues' 2025 measurements.

Cold changes three things. At 32 °F the cells return about 89% of the energy they give at 77 °F (80 to 93% across the sources), and the air is about 9% denser, by the gas law in the U.S. Standard Atmosphere.

The tires are the third: the model adds 0.5% of rolling resistance for each °F below 77 °F (0.9% per °C), a rate between Rothhämel's fit for a 42 mm tire and Bicycle Rolling Resistance's road-tire average, and holds it from 41 °F down.

Bring the bike or its pack indoors to charge in winter; Addmotor's maintenance guide sets the charging window at 50 to 77 °F.

Do the tires or the riding position change the range?

On flat ground the tire moves the figure more than your posture does. Addmotor's list gives the M-160's tires as "20'' x 4.0'' Fat Tires" with no casing named, so the model takes the median of the ten fat-bike tires Bicycle Rolling Resistance measured on its drum, bracketed by the lowest and the highest.

Each figure is a full pack spent on a flat road with 180 lb aboard. The drum's tires are 26 × 4.0; the M-160's are 20 × 4.0, the same width on a smaller wheel.

Soft tires roll heavier than any row here, so pump to the pressure on the sidewall before a long ride. The model's drag area is 0.640 m², Tengattini and Bigazzi's figure for 37 upright cruiser riders; their 0.603 m² for 90 mountain-bike riders adds about a mile at 12 mph, from 71 to 72.

Addmotor's 105 miles on PAS1, as a steady ride

Addmotor's headline figure is 105 miles on assist level 1, and on the throttle alone no steady speed in the model reaches it. The stat strip reads "per Charge (PAS1) 105 Miles"; the feature copy says "100+ MILES (PAS 1)" and "a max range of 100 miles"; and the Amazon listing under the ADDMOTOR brand says "up to 55-100 Miles".

Each cell is the steady pace on level ground at which the model spends all 960 Wh over that distance, 180 lb aboard. On the throttle alone the longest ride the model finds is about 102 miles, at under 4 mph; on the 55-mile row, steady pedaling outlasts 55 miles at any pace up to the 20 mph top.

Read that way, Addmotor's 105 miles is a ride of about 14 mph with easy pedaling or 17 mph with steady pedaling, which is what an assist level asks of you: Addmotor's own description of PAS1 is about 50% added to your pedaling power, so your legs do most of the work.

Plan on 85% of your row. Recharging "when it has a 10%-15% charge left", as Addmotor advises, leaves about 60 of the 71 throttle miles at 12 mph to plan with.

For a longer-lived pack, Addmotor's advice is to ride between 20% and 80%. In its maintenance guide the line is "keep your battery charge between 20% and 80% for the best lifespan"; that window is a 576 Wh slice, 60% of the 960:

Flat road, 180 lb aboard, using only the energy between 20 and 80%.

The formula behind the range tables

Every range table here rests on one equation, the wheel power a steady ride needs at constant speed in still air, as Martin and colleagues validated on the 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 mass of bike, rider and load together, g gravity, θ the slope's angle, Crr the tires' rolling resistance, ρ the air's density and CdA the rider's drag area. The first term carries the tires and the slope, the second the air, and three steps take the result from the wheel back to the pack:

1. Your legs reach the wheel through a chain that is 97.7% efficient, the figure Martin and colleagues measured, and the motor covers the rest of what the ride asks.
2. The motor takes its curve from a comparable hub whose numbers are public: Bafang's RM G0H0, which the 2021 OEM workbook lists at 510 rpm unloaded and 426 rpm at rated load on 48 V, "≥ 80" percent efficient, with a 90 N·m maximum. At the M-160's 48 V and 750 W, the no-load speed is then tuned so a 180 lb rider on level ground tops out at Addmotor's 20 mph, which lands it at 21.7 mph.
3. The pack heats as it delivers current, and that heat never reaches the wheel; the size of the loss comes from Arango, Lopez and Ceren's tests of a 48 V pack.

Miles = 960 Wh × the share usable at the day's temperature ÷ watt-hours per mile, with watt-hours per mile being the power the cells put out, divided by the speed in mph.

One ride, worked through: a 12 mph throttle ride over level pavement with 180 lb aboard costs 13.62 Wh a mile, traced from the tire's contact patch back to the cells. Rider and bike weigh 118.7 kg together, and keeping them at 12 mph needs 124.3 W at the wheel, 65.8 W of it for the tires' rolling resistance and 58.5 W for the air.

At 12 mph the 24-inch rear wheel turns 168 rpm. The motor fitted to Bafang's numbers makes 1.50 N·m per amp through a 0.405 Ω winding and idles at 0.83 A; this ride asks 7.1 N·m of it, a motor current of 5.5 A at 78% efficiency, below its rated 80% because the load is light.

With the pack's own losses added, the cells deliver 163.4 W, which is 13.62 Wh a mile at 12 mph; 960 ÷ 13.62 gives about 70.5 miles, or 59.9 with 15% kept back.

Before any table was trusted, the model had to reproduce two published results:

Martin and colleagues' worked example comes from their paper's Appendix I (8.36 m/s, 90 kg, a 0.3% grade), and the rated point is the RM G0H0's in Bafang's workbook. An 82% motor, 2 points over Bafang's floor, would carry the same 12 mph throttle ride 78 miles in place of 71 (Limitations item 4).

No owner's ride to an empty M-160 pack with a stated weight and speed turned up in the records read for this page (Limitations item 8), so those two checks are the tables' footing.

Carrying: 300 lb or 280 lb, and 55 lb on the rack

Addmotor prints two load limits for the M-160: "Payload Capacity 300 LBS" on the stat strip and "Max load capacity is 280 lbs" in the Measurement list. Its other documents split the same way: the Amazon listing under the ADDMOTOR brand says "The Max load capacity is 280lbs", and the July 10, 2026 folding guide says "Weight Capacity: 300 lbs".

Plan to the lower 280 lb for you and everything you carry, and email us before ordering if your total sits between 280 and 300; the weight table turns each load into miles.

The rack takes 55 lb. The list rates it "Detachable Sturdy Alloy Rack (25Kg of Max Payload)", 25 kg being 55 lb, and sizes it at 15.7 × 6.3 inches; the feature copy says "Load up to 25kg and go!" The rack's load counts inside the bike's total, so a 250 lb rider has 30 lb left for the rack under the 280 lb figure.

Brakes, lights and horn

Hydraulic disc brakes at both wheels, with 180 mm rotors. The list reads "Hydraulic Disc Brakes, Mineral Oil Rotors 180mm Front & Rear Rotors", and the debut post says the system "can be activated with minimal force".

Addmotor's brake image: the lever under the grip, with a lever and both rotors inset.

The lamps run off the main pack, and the taillight signals turns. The feature copy rates the headlight at "40 lumens" and lists the taillight's "driving light, turning left and right lights, danger light, flash light, and braking light", run from what Addmotor calls its "EB 2.0 Lighting System".

The horn is electric and loud: "a maximum decibel of 108", in the feature copy's words, with a design it says draws "on the design of car horns".

A 100 mm fork on 20 × 4.0 tires

The fork does the suspending, over tires 4 inches wide. The list gives a "Front Suspension Fork, 100mm of Travel, Adjustment and Lockout", the feature copy names it the "Addshox Front Suspension Fork" with preload adjustment, and Addmotor's 2026 folding guide repeats "100mm travel suspension fork with adjustable lockout".

Turn the lockout on for smooth pavement and off for broken ground, and set the preload once for your weight; the rear wheel is unsprung, so the 4-inch tires carry the rest of the cushioning.

Why put 4-inch tires on a folder? Addmotor's feature copy answers "All Terrain Is Accessible"; on range, the tire table shows what the fat casing costs at 12 and 15 mph.

The Mercer fit test

The Mercers, seven people who stand beside every machine we review, let you set this page's fit answers against any other review's. Each M-160 verdict below rests on Addmotor's published window, seat heights, standover or payload, or on the fit tables built from them.

Ruth, Dana and Maya sit comfortably inside; Frank, Jack and Cole are inside the window but should check a barefoot inseam against the ceiling table before ordering. Jack, at 6'1", is the rider the window admits and the top seat setting may not reach, and the tall-rider flag speaks to him.

Has it been recalled?

No. On October 12, 2026, no recall among the 10,047 on the Consumer Product Safety Commission's full recall list, from June 8, 1973 through October 8, 2026, named Addmotor, the Foldtan, the M-160 or its SKUs EB1670-20, EB1678-20, EB1676-20, EB1672-20 and EB1677-20.

Every field of every record was searched for six company names, among them Addmotor, Add Motor, Addmotor Tech and Motan, for 19 Addmotor model families including the Foldtan, and for each model code Addmotor uses. The code search caught two old laptop records carrying "M300": Sony's 2006 recall of notebook batteries, which covered the Toshiba Portege M300, and Compaq's 2001 recall of AC adapters, which covered the Armada M300.

The same search of the CPSC's list, run for three makers with recalls on file, found 1 record for Ancheer, 79 for Specialized and 40 for Trek, so the search finds a recall where one exists.

The agency's recall feed, read on the morning of October 12, held nothing newer than October 8, and all 40 of its recalls are on the full list. The CPSC's product safety warning listing, 375 entries, names neither Addmotor nor the M-160, while the same read does find both warnings it lists for one other e-bike brand.

Class and road rules for a 750 W, 20 mph folder with a throttle

In Addmotor's own words the M-160 is a "class 2 electric bike", and your state's wording decides whether the law agrees. Its April 21, 2025 roundup says "Max speed: 20 mph (class 2 electric bike that meet U.S. legal restrictions)", and its board answer of July 26, 2023 says "all class 2 electric bikes have a top speed of 20 mph".

The federal consumer-product definition, 15 U.S.C. § 2085(b), describes "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 motor power alone, with a 170-pound rider on paved level ground, is "less than 20 mph".

Left column: the words of § 2085(b); right column: Addmotor's own words from its M-160 page; both read October 12, 2026.

Both federal lines are written as "less than", and a 750 W rating sits on the watt line itself. The statute times its speed with a 170-pound rider; Addmotor's 20 MPH names no rider weight.

California's line takes the cap in: its Vehicle Code § 312.5(a) allows an electric bicycle "an electric motor that does not exceed 750 watts of power".

Screened against all 50 states and DC, Addmotor's M-160 figures sit inside 29 e-bike definitions. On October 12, 2026, each definition was checked for its watt wording, its throttle rule, its top speed and its wheel count, and Pennsylvania's for its weight limit:

Screened October 12, 2026 against the definitions in our state law atlas; the screen gives the same 29 inside for October 1.

Of the 20 outside, nineteen draw the motor line at "less than" or "fewer than" 750 watts, Alabama, Florida, New York and Texas among them, and New Jersey admits assistance only while the rider pedals, so a throttle takes a bike outside its definition.

Pennsylvania's weight line clears the M-160: 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", and Addmotor's 81.6 lb on 20-inch wheels sits inside it.

In New Jersey, the throttle is the question. The state's definition counts assistance only while you pedal, and our New Jersey e-bike law page sets out how New Jersey classes a bike that has a throttle and what that class requires of its rider.

North Carolina divides its definition into three classes on December 1, 2026, and the M-160's figures sit inside both the current text and the new one: Session Law 2026-46 keeps "an electric motor of no more than 750" watts, and its Class 2 is a bicycle whose motor "may propel the bicycle without pedaling but ceases to assist once the bicycle reaches a speed of 20 miles per hour".

A bike outside a state's e-bike definition is still regulated: that state's code places it in another class, such as a moped, with rules of its own. Each state's answer is in our 50-state e-bike law atlas, and our California e-bike law page is the most detailed single-state page we publish.

Trails, parks and public land

Off the street, the M-160 rides only where the land's manager admits e-bikes. A park path, a beach boardwalk or an RV park's lanes are open to it only when that ground's own rule says so.

On federal land the rules come in two kinds: the Bureau of Land Management writes its own e-bike definition, and the Forest Service decides e-bike access district by district. 43 CFR 8340.0-5 defines BLM's e-bike as "a two- or three-wheeled cycle with fully operable pedals and an electric motor of not more than 750 watts (1 h.p.)", a line the M-160's 750 W meets.

A BLM field office can choose to treat e-bikes as bicycles, yet that relief from the off-road vehicle rules holds 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, pedal: long stretches on the throttle with your feet still are what that condition rules out. When it lapses, 43 CFR 8341.1 confines an off-road vehicle to land designated "open to off-road vehicle use".

For National Forests, the rule is the Forest Service's directives of March 31, 2022: 87 FR 41278 sums them up as "managing all classes of e-bikes as motor vehicles", and on a Ranger District with a motor vehicle use map, 36 CFR 261.13 forbids riding "other than in accordance with those designations".

Each row's manager has the final word for that ground.

Breaking the rules in subparts 8341 and 8343 carries, under 43 CFR 8340.0-7, "a fine of not more than $1,000", imprisonment "for not longer than 12 months", or both. Our public-land e-bike guide collects each land agency's own e-bike rules.

Green flags / Red flags

Green flags

• A frame that folds to 34.1 × 20.9 × 28.3 inches, about 11.7 cubic feet, the smallest folded box our folding guide found printed on a maker's product page.
• A 960 Wh pack inside the down tube that comes out with a key for charging indoors, rated for 1,000 to 1,500 charge cycles.
• A torque sensor with seven assist levels and a half-twist throttle, on a 750 W rear geared hub.
• Hydraulic disc brakes with 180 mm rotors at both wheels, a taillight that signals turns and a 108-decibel horn.
• A 100 mm fork with a lockout on 20 × 4.0 tires.
• A 14.4-inch step that every surveyed rider from 5'2" to 6'3" clears barefoot.
• $1,499, the price Addmotor's own page showed that day, with free shipping in the contiguous states.

Red flags

Every item below is about fit: the rider the M-160 does not suit, and where that rider goes next.

• Wrong if your barefoot inseam runs past about 34.7 inches. The top seat setting falls short of the 109% formula there, which at 6'0" is at least 61 of 100 riders; send us your barefoot inseam, and we will hold it against the folders and full-size bikes we carry before you order.
• Wrong if you and your cargo pass 280 lb. That is the lower of Addmotor's two printed limits; our Graoopro review covers Addmotor's longtail with a 450 lb payload at the same $1,499.
• Wrong if one person has to carry it up stairs often. Folded it is still 81.6 lb; send us your stairs and storage, and we will match them to the lighter folders our folding guide lists.
• Wrong if you want suspension at both ends. The M-160's rear is unsprung; our Soletan M-66X review covers Addmotor's full-suspension bike at $1,799.
• Wrong if you plan to fly with it. Its 960 Wh pack is far past what an airline passenger may carry, as the FAQ sets out; the fold suits a car, a van or an RV instead.

Buy it if / Buy something else if

Buy it if you stand 5'2" to 6'3" with a barefoot inseam up to about 34.7 inches, need a bike that folds into a trunk, an RV or a closet corner, and want a torque sensor, hydraulic brakes, a 100 mm fork and about 71 miles at 12 mph on the throttle on level ground for a 180 lb rider.

It asks for a rider and cargo of 280 lb or less, a state whose wording takes in a 750 W, 20 mph bike with a throttle, the arms to lift 81.6 lb into a vehicle or a pack taken out first, and an outlet indoors for a charge of 8 to 10 hours.

For $1,499 you get a 750 W rear geared hub and a 960 Wh pack inside the frame, a torque sensor, a folding frame, a 100 mm fork, hydraulic discs with 180 mm rotors, a rack rated for 55 lb and signaling lights, at the price Addmotor's own page showed on October 12, 2026.

Buy something else if the bike never needs to fold and has to carry more, where our Graoopro review covers a 450 lb longtail at the same price; or if you want a 12-inch step and a 400 lb payload, where our Garootan M-81 review covers Addmotor's step-through cargo bike at $1,099; or if you would rather ride three wheels that fold, where our Citytan M-315 review covers one of Addmotor's folding trikes.

Our Addmotor brand profile sets the M-160 beside the other Addmotor bikes and trikes we sell, and our e-bike reviews hub lists each machine we have reviewed.

Before you buy: the checklist

Run these ten checks before $1,499 goes on your card; whether and where you may ride it rests on the first three.

1. Check your state's row in the class table, and read its full rule on its page in our law atlas.
2. Ask each park, campground or trail on your list for its e-bike rule: whoever manages the land decides.
3. Hold a barefoot inseam against the saddle and ceiling tables; a leg over about 34.7 inches belongs with the tall-rider flag first.
4. Add up rider and cargo against 280 lb, the lower of Addmotor's two limits, with no more than 55 lb on the rack.
5. Measure the trunk, closet or RV bay against 34.1 × 20.9 × 28.3 inches.
6. Plan the lift: 81.6 lb folded, or less with the pack taken out first.
7. Cost out your usual route in the range tables, hills and all, leaving 15% of the pack unused.
8. Find your steepest regular street in the climbing table at the weight you will be carrying.
9. Choose an indoor outlet between 50 and 77 °F and allow 8 to 10 hours for a full charge.
10. Plan the build with Addmotor's assembly video and its front-wheel installation video, both linked in the buying section.

Buying it from us

Why buy the M-160 from Redtail

Our listing priced the M-160 at $1,499 in White, Olive Green, Yellow, Red and Sky Blue on October 12, 2026. Addmotor's page listed $1,499 that day too, beside a struck-through $2,099, the figure our listing strikes as well. Once you order, your dealings are with us.

Four colors have a checkout link of their own; Sky Blue is ordered by email.

Every link opens checkout for that color. Addmotor's page showed four colors in stock and Sky Blue as a preorder on October 12, 2026, so Sky Blue is ordered through us by email, once we have its ship date for you.

Yellow, in Addmotor's studio image, the one color shown on black tires.

Red, in Addmotor's studio image.

White, in Addmotor's studio image.

Sky Blue, in Addmotor's studio image; all five colors share this frame.

The build has two videos behind it. Addmotor's assembly tutorial and operations guide of March 11, 2024 runs 12 minutes 48 seconds, and its front-wheel installation video of December 11, 2023 covers the step most builds start with; email us if a step stalls and we will walk you through it. In the box, the Amazon listing under the ADDMOTOR brand shows a charger, the battery and a tool kit.

Changing your mind is covered by our refund policy: a request within 72 hours of delivery, with the bike unopened in its factory-sealed packaging, returns the price less a 15% restocking fee and the return shipping, and canceling an order carries a 3% transaction fee. Questions about fit, load or route cost nothing before you order, which is the best time to ask them.

Frequently asked questions

What is the Addmotor Foldtan M-160?

A $1,499 folding step-through e-bike from Addmotor: a 750 W rear geared hub, a torque sensor and a half-twist throttle, a 960 Wh pack inside the frame, hydraulic discs, a 100 mm fork and 20 × 4.0 tires, for riders 5'2" to 6'3" (what it is).

How much does the M-160 weigh, and how small does it fold?

81.6 lb, folded or not. Folded it measures 34.1 × 20.9 × 28.3 inches on Addmotor's Specifications list, with the width given as 16.5 to 20.9 inches in the Measurement list, so measure your space against 20.9 (the fold).

Can I take the M-160 in a car, an RV or on a plane?

A car or an RV, yes; a plane, no. Addmotor's board answer is "You can put it in your car's trunk", and its feature copy says it can "fit in your RV, van or motorhome" (the fold).

A plane is ruled out by the pack: under 49 CFR 175.10(a)(18), a passenger's lithium-ion battery "must not exceed 100 Wh", or 160 Wh with the airline's approval, the same limits the FAA's PackSafe page gives, and the M-160's pack is 960 Wh.

Can the battery be removed for charging?

Yes, with the key. Addmotor's board answer of July 26, 2023 is "First you take off the protective cover of the battery. Then use the key to help you remove the battery." (the battery).

How fast does the M-160 go, and what class is it?

20 mph, on the stat strip. Addmotor's April 2025 roundup calls it a "class 2 electric bike", and whether your state agrees depends on its wording: Addmotor's figures sat inside the definitions of 29 of the 51 jurisdictions screened on October 12, 2026 (the class table).

How far can the M-160 go on one charge?

Addmotor's stat strip prints "per Charge (PAS1) 105 Miles". On the throttle over level pavement, the model gives a 180 lb rider about 71 miles at 12 mph and 41 at the 20 mph top, and about 57 at 12 mph with 300 lb aboard; each 1,000 feet climbed at 10 mph costs 138 to 160 Wh (the range tables).

How long does the battery take to charge, and how long does it last?

8 to 10 hours for a full charge, on Addmotor's Specifications list, which rates the pack for 1,000 to 1,500 charge cycles. Addmotor's own advice for a longer life is to keep the charge between 20% and 80% (the battery).

What is the weight limit of the M-160?

280 lb or 300 lb, depending on where you read. The Measurement list says "Max load capacity is 280 lbs" and the stat strip "Payload Capacity 300 LBS"; plan to 280 for rider and cargo together, with up to 55 lb on the rack (carrying).

How tall do I need to be to ride the M-160?

Addmotor's rider window for it runs from 5'2" to 6'3". The seat tops out 37.8 inches off the ground, which meets the 109% formula for a barefoot inseam up to about 34.7 inches; at 6'0", at least 61 of 100 riders need more, so measure your inseam against the ceiling table before you order.

Does the M-160 have a torque sensor, and what does it do?

Yes: the assist follows how hard you push on the pedals. Addmotor's debut post says the lowest level adds "approximately 50%" to your pedaling power and the highest "about 300%", and the half-twist throttle moves the bike without pedaling (the motor).

Why does a folding bike have fat tires?

For ground a thin tire handles badly. Addmotor's feature copy says the 4-inch tires make "All Terrain Is Accessible", and the tire table prices the trade in miles.

How hard is the M-160 to assemble?

Two Addmotor videos cover it, both linked in the buying section: an assembly tutorial and operations guide of nearly 13 minutes, and a front-wheel installation video. Stuck partway through the build? Email us and we will talk you through the step.

Is Addmotor a good bike brand, and where are its bikes made?

It has a long public record: Addmotor dates its start to 2011 in El Monte, California, on its About page, keeps its warehouse and showroom there, at 4188 Arden Drive, and says it "has its own factory for designing and manufacturing products". To learn where the M-160 itself was built, email us and we will put the question to Addmotor. Our Addmotor brand profile lays out its trademark record, its dealers and every Addmotor model we carry.

Is the Addmotor Foldtan M-160 worth it?

If you fit the 5'2" to 6'3" window and need a bike that folds, the case is $1,499, Addmotor's own price that day, for a 750 W torque-sensor folder with hydraulic brakes and a 960 Wh pack that computes to about 71 miles at 12 mph on the throttle on level ground for a 180 lb rider (the verdict).

Limitations of this review

Twenty points this review leaves open:

1. We sell this bike. Give the red flags your first read; they matter as much as the green.
2. Every figure is tied to a source: specification-verified against Addmotor's published documents, a statute or regulation, our store record, a cited study, or the arithmetic printed beside it.
3. Each range row is an ideal ride: a single speed and grade, still air and no stops. Pulling away from a light, riding into wind or crossing wet grass all cost more than any row shows.
4. The motor in the model is a Bafang curve standing in for Addmotor's, its 90 N·m torque cap included: the M-160 documents read give its motor a 750 W rating and no torque or speed curve. At 82% efficiency, 2 points over Bafang's 80% floor, the 12 mph throttle ride would come to 78 miles in place of the table's 71.
5. Light-load pedaling is the model's weakest ground. At 12 mph and slower with easy pedaling, the result hangs on the motor's losses at light load, a region between the two points, rated and no-load, that Bafang's workbook gives.
6. 750 W is the model's ceiling, so a short, steep pitch may go faster on the bike than the steady climbing speeds in the table.
7. The no-load speed is fitted to Addmotor's 20 mph, so a 180 lb rider on the throttle just reaches it; if the real motor spins faster and a limiter holds it back, its draw near 20 mph would differ slightly.
8. No owner's ride to an empty pack with a weight and a speed is on record for the M-160. Addmotor's two captioned videos of the bike, of July 25, 2023 and November 27, 2023, carry music only, and Electric Bike Mark's preview of August 2, 2023 reads out Addmotor's specifications without a ride, as does a creator's filming video that features the bike, all read on October 12, 2026; no captions could be read for an affiliate review posted on July 27, 2026. An owner on Reddit wrote in February 2024 that it "gets about 100 miles to a charge" without a speed, a weight or an assist level, and the single owner review on Addmotor's page is about delivery. The two published checks in the formula section carry the tables.
9. Every table counts the full 960 Wh as usable. The Addmotor documents read for this page do not say how much the battery management releases; when researchers at KIT put one pedelec through a standard bench range test, 75% was.
10. The tire figure is the median of ten 26 × 4.0 fat-bike tires measured on a drum, standing in for the M-160's own 20 × 4.0, whose casing Addmotor's list leaves unnamed; the tire table shows the spread.
11. One laboratory cell carries the cold table. Addmotor names Samsung as the maker without a cell model, so the central line follows McMaster University's LG HG2 measurements, with Samsung's and others' published data in the brackets.
12. The measurement drawing is not used as a ruler. Its five control lines imply 10.3 to 11.2 pixels per inch, no scale brings more than two other lines within 3.5% of their figures, and so the saddle table stops at the formula's distance; the rest is your tape measure's job.
13. Read the ceiling counts as minimums, and the floor count as unknown. The pedal's height above the ground is missing from both: adding it could only push more tall riders past the top setting, and only it could say whether the 4 of 100 at 5'2" fit the lowest one.
14. Lean and hand load are not computed. No seat angle, bracket height or grip position is in the documents read, so those subsections give guidance, and the hand-load figure they quote was measured on road racers on their hoods, a stretched position unlike the one the M-160's raised U-shaped bar sets in Addmotor's images.
15. Each saddle distance is a place to start. It is 109% of the median inseam at your height, and the heel check on the bike takes you the rest of the way to a knee bent 25 to 35 degrees.
16. An Army survey underlies the fit tables. Between 2010 and 2012, ANSUR II measured 6,068 US Army personnel aged 17 to 58, who are not a sample of the US public, so let your own measured inseam pick the row.
17. Addmotor's documents give the M-160 two of several figures: payloads of 300 lb on the stat strip and in the July 10, 2026 folding guide, and 280 lb in the Measurement list and on the Amazon listing under the ADDMOTOR brand; ranges of 105 miles on the stat strip, "100+ MILES (PAS 1)" in the feature copy, and "up to 55-100 Miles" on the same listing; and prices of $1,599 in the June 8, 2026 safety roundup and $1,499 on the page that day. All are printed; the model uses the page's figures and both payloads.
18. "UL 2271" appears in Addmotor's April 21, 2025 roundup without a certificate number; ask us and we will request the pack's own certificate from Addmotor.
19. Each verdict in the class table comes from screening our law atlas's definitions as of October 12, 2026. Definitions move (North Carolina's will on December 1), and how a state treats a bike outside its definition was not read in every state.
20. Prices, stock and checkout options date from October 12, 2026, during Addmotor's Prime Month sale; our price follows Addmotor's when it changes, and a checkout can show store-wide discounts that this page does not list.

The bottom line

At $1,499, the Foldtan M-160 puts a 750 W rear geared hub and a 960 Wh pack inside the frame on a step-through that folds to 34.1 × 20.9 × 28.3 inches, with a torque sensor, a half-twist throttle, a 100 mm fork, hydraulic discs and 20 × 4.0 tires.

The model gives a 180 lb rider about 71 miles at 12 mph on the throttle over level pavement, about 57 with 300 lb aboard, and about 14.0 mph up an 8% grade at 180 lb.

Its owner stands 5'2" to 6'3" with a barefoot inseam up to about 34.7 inches, carries 280 lb or less, rides where the state's wording takes in a 750 W bike with a throttle, and has a trunk, an RV bay or a closet for an 81.6 lb fold. A full charge costs about 18 cents at the July 2026 US average price of electricity.

Settle two questions with us before checkout: whether the top seat setting reaches your leg, and which class your state puts the bike in. Send your height, inseam, weight and state in one email, and one reply will answer both.
