Addmotor Garootan M-81 Review: $1,199 Cargo eBike

Step-through cargo e-bike · 750 W rear hub motor, speed sensor, half-twist throttle · 48 V pack, 15 Ah in the Technical tab and 20 Ah in the feature copy · 12-inch standover · 25.8-inch integrated rear rack · hydraulic disc brakes · 100 mm fork · 20 × 4.0 fat tires · 400 lb payload · 20 mph · $1,199 · verified October 2, 2026

Quick Answer — Addmotor's Garootan M-81 is a $1,199 step-through cargo e-bike with a 12-inch standover, a 25.8-inch rear rack, a 750 W rear hub motor and a 400 lb payload. On level pavement at 12 mph on the throttle, one 180 lb rider computes to about 52 miles on the 15 Ah pack and 70 on the 20 Ah pack.

Addmotor prints both packs on its own page, so the battery section sets them side by side. It sizes the M-81 for riders 5'4" to 5'9" on a seat post that runs 33 to 42 inches off the ground, and whether a child may ride the rack is your state's call, quoted in the passenger section.

How we verified this Addmotor Garootan M-81 review

Every specification is read from Addmotor's M-81 page, its tabs re-read on October 2, 2026, its size drawing, the bike's question board and the 49 Addmotor posts that name the M-81. Our price, colorways and Shop Pay plans were read the same day.

Range and fit are computed, and each formula shows its inputs. The review is specification-verified: each figure traces to Addmotor, a statute, our store or arithmetic on this page. We sell this bike, so weigh the red flags as carefully as the green.

Addmotor's Garootan M-81 specification

One frame, one motor, five colorways, and a Size & Fit table with a single column.

Addmotor's Size & Fit tab, read October 2, 2026; the handlebar row is from the size drawing, which the table omits.

Addmotor's Technical and Performance tabs, feature copy and stat strip, read October 2, 2026. Where two of the page's own parts print different figures, both rows are quoted, and the battery section explains which one each table on this page uses.

A 12-inch step and a 25.8-inch rack

The M-81 is a compact cargo bike: a step-through frame on two 20-inch fat tires, with a long rack bolted into the frame behind the saddle. Addmotor titles the page "Addmotor M-81 Step Through Cargo Electric Bike" and writes that it can "transport up to 400 lbs"; its page invites you to "Enjoy City Rides with Your Kids or Relaxing Outdoor Evenings".

Orange, in Addmotor's studio photograph, the rack running back from the seat tube to the rear axle's line.

At 75 inches long on a 51-inch wheelbase, it sits closer to a full-size bike than to a longtail. The frame drops to 12 inches in front of the saddle in Addmotor's table, so you step through rather than swing a leg over, and the rack is part of the frame: the feature copy calls it "an integrated rear rack suited for outdoor hobbyists".

Addmotor has written about the M-81 since October 2022, and its payload figure has moved. Addmotor's posts from 2022 and 2023 print a 350 lb payload, and from July 2024, 400 lb; its range reads "105+" miles in posts since 2022, with 80 miles on assist level 1 in others. Addmotor's post of January 29, 2026 lists "Weight 85 LBS" and "Payload Capacity 400 lbs", as today's tabs do.

That history matters when you compare listings or shop used: a page quoting 350 lb repeats Addmotor's figure of 2022 and 2023. Every figure in this review is from the current page unless it is dated.

Does the M-81 fit you? Saddle 33 to 42 inches

Addmotor sizes the M-81 for riders 5'4" to 5'9", and a pedaling formula puts the saddle top 33.3 to 36.1 inches from the pedal for the median rider across that window. The saddle itself is listed 33 to 42 inches above the ground, so the question is how far the pedal sits below it.

Asked why riders under 5'4" are left out, Addmotor answered on October 21, 2025: "This is a general guideline, and individual fit can vary."

The formula is the saddle 109% of your inseam from the pedal axle at the bottom of its stroke, the height Peveler and colleagues found produced the most power. Addmotor publishes the saddle's height off the ground but no bracket height and no crank length, so this review gives the distance each height needs and lets a tape measure close the gap.

Three steps fit you to it:

1. Measure your inseam barefoot. Stand against a wall, press a hardcover book up between your legs as a saddle would, and measure floor to spine.
2. Find your height in the table below and read the saddle-top-to-pedal distance for your row.
3. Set the saddle on the bike with one crank pointing straight down along the seat tube, and measure from the saddle top to the center of that pedal.

Addmotor's size drawing over its studio photograph of the Orange M-81. It shows the saddle at both of its listed settings; the formula subsection explains why nothing is measured on it.

How high does my saddle go?

Find your row and set the saddle top that far from the pedal axle. The middle column is the formula at 109% of your height's median inseam; the last two are the ends of the range Ferrer-Roca and colleagues published, 106 and 110.4%.

From 6,068 measured bodies in the US Army's ANSUR II survey: the inseam column spans the 5th to 95th percentile at each height, and the three distance columns are for that height's median inseam. Your own inseam moves your row: at 109%, each inch of inseam adds 1.09 inches.

Addmotor's 33 to 42 inches are measured to the ground, and the pedal axle sits above the ground at the bottom of its stroke. So the saddle's lowest setting puts it less than 33 inches from the pedal, and its highest less than 42; how much less depends on the bracket height and crank length, which Addmotor does not print. A tape measure on the bike settles it in a minute.

Can I step through it at a stop?

Yes, at every height in the survey. Addmotor lists a 12-inch standover, and every rider from 4'11" to 6'4" in the survey clears it barefoot.

Barefoot inseam against Addmotor's 12-inch standover, the same bodies as the saddle table; the inseam column is each height's median. Even at 4'11", 95 of every 100 riders clear it by 14.8 inches or more.

The low frame is what lets you put a foot down with a child or a load on the rack behind you: you stand astride the frame tube rather than leaning the bike over to clear a top tube.

Will I lean forward to reach the bars?

Your lean on the M-81 is not computed here, because the grip position is not published. Addmotor prints an 18-inch reach and a 40.4 to 44.1-inch handlebar height on its drawing, but no seat angle and no grip position against the saddle, and its drawing did not scale cleanly enough to measure them (the formula subsection prints every comparison).

The swept-back bar on the adjustable stem, in Addmotor's close-up.

What Addmotor does give you is adjustment. The feature copy describes "An adjustable stem" that lets you "find the perfect angle for a comfortable upright position while riding", and the drawing's 40.4 to 44.1 inches is the bar's height range above the ground.

How much weight goes through my hands?

Not computed here, for the same reason. The share of your weight on the grips follows from your lean, and your lean needs the grip's position against the saddle, which Addmotor does not publish. For scale, ten road racers on their brake hoods in Carahalios's 2015 laboratory study carried 15% of their weight on the bars, a forward position the M-81's swept-back bar does not ask of you.

Set it by feel instead: raise the stem until your shoulders relax with your elbows slightly bent, then ride a few blocks before changing it again. A swept-back bar like the M-81's brings the grips toward you, which keeps the torso upright.

How do I set the saddle at home?

Set the height from your row, then check it with your knee. With the pedal at the bottom of its stroke and your heel on the pedal, your leg should be straight; on the ball of your foot, the knee then bends 25 to 35 degrees, the target Peveler and Green measured.

If you carry a child or a load on the rack, set the saddle before you load it, since a heavy rack makes the bike harder to hold while you stand astride and adjust the post.

The fit arithmetic, step by step

The saddle table rests on one rule: the saddle top 1.09 times your inseam from the pedal axle at the bottom of the stroke. For a 5'8" rider on the median 32.6-inch inseam, that is 35.6 inches; LeMond's rule, 88.3% of inseam from the crank axle, gives 28.8 inches for the same rider.

The two rules measure from different points, the pedal and the crank axle, and converting one into the other needs the crank length, which Addmotor does not print. So both are given as published, and neither is turned into the other.

The drawing was checked as a measuring source and did not hold to one scale. Scaled by the 51-inch wheelbase, hub to hub, it reproduces only one of Addmotor's other printed dimensions within 3.5%; scaled by the 75-inch length, again only one:

Points read on Addmotor's size drawing to ±3 px. The two saddles it shows are drawn about 6 inches apart against the 9-inch range it labels, so the drawing illustrates the settings rather than measuring them, and no seat angle or grip position is taken from it.

A 750 W rear hub motor, a speed sensor and a throttle

Addmotor rates the motor at 750 W and puts it in the rear hub. The Technical tab lists a "750W Rear Brushless Gear Motor", and an undated Addmotor post on its 750 W fat-tire bikes calls the M-81's a "750W BAFANG brushless geared hub motor".

For the peak, Addmotor's comparison image gives "(1400W Peak, 90Nm Torque)", while its Black Friday 2025 post gives "907W peak", as its 2023 posts gave "907 peak watts". The range model takes the image's 90 N·m; both peaks sit side by side in Limitations, and neither changes a range table, which runs on the motor's rated curve.

The speed sensor starts the motor once the cranks turn, at whichever of the assist levels you choose, and the half-twist throttle moves the bike with your feet still. The display's feature copy speaks of "increased speed to 7 PAS", seven assist levels.

The EB 2.0 display, in Addmotor's close-up; the feature copy says its turn-signal arrows "give an extra guarantee of your safety while riding".

Your pedaling runs through a Shimano 7-speed. The range model treats the hub motor as driving the wheel apart from your chain, so the gear you pick sets only your own cadence. How your state classes a 750 W, 20 mph bike is in the class section.

15 Ah or 20 Ah: the battery Addmotor prints two ways

Addmotor's page names two packs for the M-81. The Technical tab reads "48V/15Ah UL-certified Battery", 720 watt-hours, and one gallery title says "15Ah UL-Certified Battery With Samsung Cells"; the feature copy reads "48V*20AH UL-2271 certified Samsung Battery Cells", 960 watt-hours, and so do the stat strip and two images Addmotor uploaded in March 2026.

The pack, cropped from Addmotor's key-components image, which labels it 48V 20Ah.

Every Addmotor post that names the M-81 and prints a pack gives it 20 Ah, the newest dated January 29, 2026. The range section computes both packs. Its tables use the 15 Ah of the Technical tab as the central case, because the table is the page's specification block, and print the 20 Ah figures beside them.

Ask us which pack ships with your order before you pay. Our own listing prints the 15 Ah pack; email us and we will confirm the pack, and its watt-hours, with Addmotor in writing.

A full charge on the 2-amp charger takes about 7.5 hours from empty on the 15 Ah pack and 10 on the 20 Ah, by the arithmetic of amp-hours over amps. Addmotor's battery-health post advises recharging "when it has a 10%-15% charge left".

Its maintenance guide adds: "keep your battery charge between 20% and 80% for the best lifespan", charging "at room temperature (between 10 and 25 degrees Celsius)", 50 to 77 °F. Addmotor's 20 Ah Samsung pack lists the M-81 among the models it fits, so a second pack is the way to ride farther in a day.

Range: how far a charge takes the M-81

On level pavement with the throttle alone, one 180 lb rider computes to about 52 miles at 12 mph and 30 at 20 mph on the 15 Ah pack, and 70 and 41 on the 20 Ah. Easy pedaling at 12 mph stretches the 15 Ah figure to 109 miles; a steady 8% climb at 10 mph on the throttle cuts it to about 9.

Three steps turn your ride into miles:

1. Find your pace and effort in the first two tables, and for a child or cargo on the rack, the load table.
2. Add the climbing: 142 to 183 Wh per 1,000 feet at 10 mph on 4 to 10% grades on the throttle, or 128 to 164 Wh with easy pedaling (the hills table).
3. Correct for the air temperature, then count on 85% of the pack.

Each row is one steady ride. The inputs are 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, and the formula subsection works one ride through by hand.

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

Pace decides more than anything you can change on the bike: on the 15 Ah pack, 67 miles at 8 mph, 52 at 12, 30 at 20. The air's share of the work rises with the cube of speed.

A 180 lb rider on the throttle alone, level pavement, air at 77 °F. The 15% column keeps back the top of Addmotor's "10%-15%" recharge advice; with 15% kept, the 20 Ah pack gives 60 miles at 12 mph and 34 at 20.

Pedaling adds to every row. Easy pedaling here is 75 W and steady pedaling 150 W; with the motor off, those efforts alone hold a 180 lb rider on the M-81 at about 8.9 and 13.0 mph on the flat.

The 15 Ah pack, one 180 lb rider, level pavement. "Legs alone" means 150 W from you holds that speed with no help. The 109 and 130-mile cells depend on the motor's losses at light load, the model's least-checked part (Limitations item 6).

The assist level only decides how the work is shared between you and the motor; the speed and your effort set the miles. With the speed sensor, the motor adds its power once the cranks turn, so easy pedaling on a low assist level is the way to the middle column.

Does shifting gears save battery?

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

Pack watt-hours per mile for a 180 lb rider in 77 °F air. At 12 mph on level ground, 150 W of steady pedaling carries the pace by itself and the motor draws nothing.

Choose the gear for a cadence you can hold, and drop a few before you stop, so a loaded rack starts from rest with your legs sharing the push.

What does a climb cost the pack?

A 1,000-foot climb at 10 mph costs 142 to 183 Wh more than the same miles on the flat on 4 to 10% grades with the throttle doing the work, or 128 to 164 with easy pedaling. Lifting rider and bike is 55 to 70% of the throttle figure; the rest is heat in the motor and pack.

A 180 lb rider on the 85 lb bike makes 265 lb to lift, and 1,000 feet of height takes about 100 Wh at the wheels. Up 8% at 10 mph on the throttle the pack spends 167 Wh per 1,000 feet, so all 720 Wh would lift that load about 4,300 feet with nothing left for the flat.

All at 10 mph with one 180 lb rider on the 15 Ah pack; the last column adds 75 W of easy pedaling. The model gives nothing back on the descent, which keeps it on the careful side.

A loaded rack slows the climb. The motor's torque sets the speed it can hold on a grade, and the heavier the bike and its load, the lower that speed:

The fastest steady speed the model's motor holds on each grade with one 180 lb rider, a rider and cargo totaling 260 lb, or Addmotor's full 400 lb aboard, throttle only except the third column. The pack size changes the miles; these speeds stay the same.

Plan a hilly day as flat miles plus climbing. Twenty level miles at 12 mph on the throttle take about 274 Wh, and 1,000 feet of 8% grade about 167 Wh: the day needs about 441 Wh, 72% of the 612 Wh in 85% of the 15 Ah pack. On the 20 Ah pack, whose larger pack loses less as heat, the same day takes about 437 Wh, 53% of its 816 Wh.

How far does a child or cargo on the rack take the range?

On the flat, every 40 pounds you add costs about three miles at 12 mph; on a climb, much more. Weight adds to the tires' work and the grade's and none to the air's, so the gap widens as the road tips up.

The weight column counts you, anyone or anything on the rack and what you wear; the model adds the bike's own 85 lb, and every cell is throttle only on the 15 Ah pack. At 400 lb, 10 mph up 8% asks more torque than the model's motor gives, and the climbing table gives the 8 mph it holds instead.

A 180 lb rider adding 80 lb of child, seat and groceries goes from 52 miles to 46 at 12 mph, and from 43 to 38 at 15 mph. At Addmotor's full 400 lb, 37 and 32. On the 20 Ah pack each flat figure is about a third larger, since the pack holds a third more energy and the watt-hours per mile barely change; the climbing column gains 35 to 40%.

How much range does cold weather take away?

Plan on about a fifth less at freezing. A 12 mph throttle ride good for 52 miles in 77 °F air comes to about 41 miles at 32 °F and about 38 at 14 °F on the 15 Ah pack.

Level ground, one 180 lb rider, the 15 Ah pack, 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 the rows between interpolated; Addmotor names Samsung as the cell maker, so the brackets use Samsung data sheets.

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

Three losses stack in cold air: the cells return less energy, the air is denser by the U.S. Standard Atmosphere's gas law, and the tires stiffen. The model raises their 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.

Charge the pack indoors. Addmotor's maintenance guide puts charging at 50 to 77 °F, and its posts call the pack "removable", so it can come inside with you.

Does the tire or the riding position change the range?

On the flat, the tire matters most. Ten 26 × 4.00 fat tires drew 23.2 to 42.1 W on Bicycle Rolling Resistance's drum at 12 psi. They are 26-inch and the M-81's 20-inch, so the model takes the median of the ten, a coefficient of 0.0105, with the lowest and highest as brackets.

Full-charge miles on the 15 Ah pack, one 180 lb rider, level ground. Kenda's Juggernaut Pro sets the high bracket, 0.01262 on its own measurement page.

Grass, gravel and sand are off these pavement tables; send us your route and we will price its paved miles and climbs. For the air, Tengattini and Bigazzi measured 0.640 m² of drag area across 37 upright cruiser riders, the value used here; their 0.603 m² for mountain-bike riders adds about a mile at 15 mph, 43 to 44.

Addmotor's 75, 80 and 105 miles, as steady rides

Each of Addmotor's distances reads as a steady ride in the model. The Technical tab prints "75 Miles (PAS1)" for the M-81, and the stat strip "105+ MILES" "Per Charge (Estimate)"; an undated Addmotor post says "the M-81 can achieve 80 miles on PAS1 per charge" on the 20 Ah pack.

For each distance, the steady level-ground speed at which the model spends the whole pack with one 180 lb rider: 9.6, 12.0 and 9.1 Wh a mile, top row to bottom. "Walking pace" means the throttle alone reaches the distance only below about 5 mph, and "never" that it falls short at every speed, about 101 miles at most.

Read that way, Addmotor's 75 and 105 miles are unhurried rides with your legs in the work, about 14 mph with 75 W from you, and its 80 miles is a slow throttle ride or a quick pedaled one. Hold 12 mph on the throttle and the model's 52 and 70 miles land below them.

To spare the cells, ride inside the 20–80% band. That window, 60% of the pack, is what Addmotor's maintenance guide means by "keep your battery charge between 20% and 80% for the best lifespan":

Miles inside the band on the 15 Ah pack, 432 of its 720 Wh, one 180 lb rider, level ground. At 8 mph the easy-pedaling cell reads "legs alone" because 75 W by itself holds this rider at about 8.9 mph.

The formula behind the range tables

The power the rear wheel needs at a constant 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 ]

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

1. Your pedaling reaches the wheel through the chain at 97.7% efficiency, the chain figure Martin and colleagues measured, and the motor supplies the rest.
2. The motor takes the curve of a comparable hub motor with published figures: for its RM G0H0, Bafang's 2021 OEM workbook lists 510 rpm unloaded, 426 rpm at rated load at 48 V, and "≥ 80" percent efficiency. The model keeps that curve at Addmotor's 48 V and 750 W and sets the unloaded speed at 21.7 mph, where one 180 lb rider on the throttle just reaches Addmotor's 20 mph on the flat.
3. The pack turns a small share into 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: the pack's watt-hours (720 for 15 Ah, 960 for 20 Ah) × the share usable at that temperature ÷ watt-hours per mile.

One ride worked from the wheel back to the pack: one 180 lb rider, 12 mph on the throttle, level pavement, the 15 Ah pack. Rider and bike come to 120.2 kg, and the wheel needs 125.1 W, 66.7 W of it for rolling resistance and 58.5 W for the air.

At 12 mph the 24-inch wheel makes 168 turns a minute. Fitted to Bafang's figures, the motor model has 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 for 7.1 N·m on 5.5 A, which it delivers at 78% efficiency, under the rated 80% because the load is light.

With the pack's internal losses added, 164.6 W leaves the cells; at 12 mph that is 13.72 Wh a mile, and 720 ÷ 13.72 is about 52.5 miles, 44.6 with the 15% reserve held back.

Two published benchmarks, reproduced before any figure was computed:

Before the tables were run, the model reproduced Appendix I of Martin and colleagues and the rated point of Bafang's RM G0H0.

No measured ride on the M-81 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 49 Addmotor posts naming it were read on October 2, 2026; their range figures state no speed or rider weight.

Carrying: a 400 lb budget and a 25.8-inch rack

The 400 lb counts you, everything on the rack and everything you wear. The Technical tab prints "Payload: 400 LBS", and Addmotor's posts from July 2024 on print the same; the posts of 2022 and 2023 printed 350 lb, as the bike's history records.

A child seat fitted to the rack in Addmotor's photograph; no child seat comes with the M-81.

The rack is 25.8 inches long and 6.5 inches wide, and part of the frame. For the rack alone, Addmotor's post of October 13, 2023 gives "an amazing payload capacity of 100 lbs of the rear rack"; today's tabs print no rack figure, so email us and we will confirm it with Addmotor before you load the rack near it.

A crate and fishing gear on the rack in Addmotor's image, with the tire size marked.

The passenger pad in some of Addmotor's photographs is not sold. Asked whether it could be bought, Addmotor answered on January 31, 2023: "Thanks for asking, we're sorry that we don't have that passenger pad for sale now." Asked about a long basket, it answered on October 21, 2025 that it does "not have a long rear basket available for sale as a standard accessory for this model".

A child seat, a basket or crate and panniers are yours to choose, and the rack's 6.5-inch width is the figure to check against a seat or rack-top bag's mounting before you buy one. The passenger section quotes what each state's code says about carrying a child.

Hydraulic disc brakes, turn signals and lights

Hydraulic discs front and rear, on 180 mm rotors. The Performance tab lists a "Hydraulic Disc Brake", and the feature copy pairs it with "180mm rotors": "Whether you're carrying heavy loads or riding at high speeds, these brakes deliver consistent performance for a smooth and safe ride."

The two calipers and rotors, and the lever beside the grip, in Addmotor's image.

Brake earlier with a load on the rack. With a child or cargo aboard, start slowing sooner, keep both hands on the levers, and practice a few loaded stops before your first errand.

The light set is part of what you pay for. The Performance tab gives the headlight "a brightness of 40 lumens, a visible distance of 200m, and a 180° side view", the feature copy calls it an "IPX5 design", and the taillight carries "left and right turn signals, danger light, flashlight, brake light", switched from the bar.

The taillight's five modes, in Addmotor's light-system image.

A 100 mm fork and 20 × 4.0 fat tires

A fork up front, the fat tires at both ends. The Performance tab lists an "Oil Spring Fork with 100mm of Travel"; the rear has no shock, so the 4.0-inch tire and the saddle take the bumps behind you, and whoever rides the rack feels the road through the tire alone.

The Performance tab names "Kenda GIGAS Puncture-resistant 20" X 4.0"" tires; in Addmotor's studio photographs and size drawing the sidewalls carry the KRUSADE name beside Kenda's. Either way they are 20-inch fat tires, and the feature copy credits their "large convex glue tread patterns" with helping "avoid a flat tire".

Addmotor's January 29, 2026 post says the fat tires make the M-81 "suitable for pavement, gravel, and mixed terrain"; the range tables price pavement only.

85 pounds, 29 inches wide, 75 inches long

Plan for 85 lb, 29 inches of width and 75 inches of length, the Technical tab's weight and the Size & Fit table's width and length. Addmotor's post on its 750 W fat-tire bikes lists the M-81's pack as a "removable battery", so take it off before you lift the bike.

Measure the door and the stairs before delivery. At 29 inches wide the bike needs a door at least that wide, and 75 inches of floor along a wall to park. A ground-level spot spares you carrying 85 lb, more with a child seat fitted.

The Mercer fit test

The Mercers, the same seven people in every review we publish, are measured against this bike so you can compare fit answers from page to page. Each verdict reads a figure Addmotor publishes, its rider window, standover, saddle range and payload, or the fit tables built on them.

Ruth, Dana and Maya sit inside Addmotor's window, and Frank, Jack and Cole above it. For the three taller riders, the saddle's 42-inch top setting is the figure to set against their rows, and the verdict names bikes on our shelf sized higher.

Has it been recalled?

No. On October 2, 2026, the Consumer Product Safety Commission's recall data held no recall naming Addmotor, the Garootan or the M-81.

The search ran the title, product-name and manufacturer fields for Addmotor, ADDMOTOR, Add Motor, Addmotor Tech, Motan and Addrider and 19 Addmotor model families, Garootan among them, and read every field of a 623-record corpus of bicycle, e-bike, battery and scooter recalls for the brand and its model codes.

An empty answer counts only because the search finds recalls that exist: in the same run, Ancheer returned 1, Specialized 54 and Trek 24.

Class and road rules: where a 750 W cargo bike lands

Your state's words decide how the M-81 is classed. Addmotor's page publishes 750 W, a throttle and 20 mph, the three figures the federal definition draws its lines at.

15 U.S.C. § 2085(b) calls a low-speed electric bicycle "a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.)" whose top speed on the motor alone, with a 170-pound rider on a paved level surface, is "less than 20 mph".

Both columns read October 2, 2026: the statute from § 2085(b), the bike from Addmotor's page.

Addmotor's 750 W and 20 mph each sit on a line the statute draws at "less than". The 20 mph is Addmotor's own figure, not the statute's motor-only test with a 170-pound rider, so no spec table can say where the bike lands on that test.

California draws its line inclusively: California Vehicle Code § 312.5(a) defines an electric bicycle with "an electric motor that does not exceed 750 watts of power".

Across the 50 states and DC, screened on watt wording, throttle rule, top speed, wheel count and Pennsylvania's weight limit, Addmotor's published figures for the M-81 sit inside 29 jurisdictions' e-bike definitions and outside 20 on October 2, 2026. Alaska and Kentucky publish no e-bike definition.

Each state's definition was screened on October 2, 2026 as our state law atlas records it. Nineteen of the 20 set the motor limit at "less than" or "fewer than" 750 watts, a line a 750 W motor does not pass. New Jersey's turns on its throttle rule. Pennsylvania's "not more than 100 pounds" takes in the M-81's 85 lb.

The screen does not test the words of two inside rows. South Carolina's sets "a top motor-powered speed of less than twenty miles an hour when operated by a rider weighing one hundred seventy pounds", the federal line again, and Connecticut's "not more than seven hundred fifty watts" took effect October 1, 2026 under Public Act 26-24 § 26.

North Carolina rewrites its definition into three classes on December 1, 2026; Session Law 2026-46 keeps "no more than 750 watts", and its class 2 motor "may propel the bicycle without pedaling but ceases to assist once the bicycle reaches a speed of 20 miles per hour", so the M-81's row stays inside.

Where a state leaves the M-81 outside its e-bike definition, it still decides how the bike is treated, as a moped, a motor vehicle or otherwise. Each state's answer is in our 50-state e-bike law atlas, with a California page of its own.

Carrying a child or a passenger: what your state's code says

In 26 of the 29 jurisdictions whose definitions take in the M-81, the bicycle code limits riders to what the bike is designed or equipped to carry, or asks for a seat; and in eleven, the code writes in how a young child may ride. We read the passenger rule in each of those 29 and checked every quote against the statute's text on October 2, 2026.

The M-81 comes with a rack and no passenger seat: Addmotor's January 31, 2023 answer says the pad in its photographs is not sold. So the question for a parent is what a child seat on the rack meets in each state's words.

Each rule was 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 were read in a FindLaw copy of the code. In the sections read, New Mexico puts an e-bike inside "bicycle" only for its helmet act, so whether its passenger rule reaches the M-81 is open; the row prints the rule as written.

Eleven of the 29 write in a young child, and most of them a child seat or carrier. The words differ by state:

Quoted 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.

Three states ask for a seat for every passenger, and a rack is not one. In California a passenger rides "upon or astride a separate seat attached thereto" (§ 21204(b)); in Massachusetts, on "a permanent and regular seat attached to the bicycle" (c. 85, § 11B); and Maryland's bicycle needs "a seat securely attached to it for each passenger" (§ 21-1203(b)).

North Carolina's child rules in § 20-171.9 call for a helmet under 16 and a restraining seat for a passenger under 40 lb or 40 inches. They attach to a "Bicycle" that § 20-171.8 calls "a human-powered vehicle", so whether they reach an e-bike is open both ways; read them as the safe course.

Trails and public land: whose rule applies

Off pavement, the agency that manages the land decides where the M-81 may go. On federal land the Bureau of Land Management draws its own 750 W line for an e-bike, and the Forest Service decides district by district.

On BLM land, 43 CFR 8340.0-5 defines an 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.)", which takes in the M-81's 750 W.

A field office can decide that e-bikes ride as bicycles, and that decision holds only while "the motor is not exclusively propelling the e-bike for an extended period of time". A long stretch on the throttle meets that condition head on; where the exception does not apply, 43 CFR 8341.1 keeps off-road vehicles to land designated "open to off-road vehicle use".

In National Forests, the directives of March 31, 2022 manage "all classes of e-bikes as motor vehicles", as the notice at 87 FR 41278 records, and 36 CFR 261.13 prohibits riding "other than in accordance with those designations" where a district has published its motor vehicle use map.

The land manager's own document settles each row; our public-land e-bike guide goes through each agency's rules.

Green flags / Red flags

Green flags

• A 12-inch standover that every rider in the survey from 4'11" to 6'4" clears.
• A 25.8-inch rack built into the frame and a 400 lb payload for $1,199.
• Hydraulic disc brakes on 180 mm rotors, with turn signals and a brake light on the taillight.
• A 750 W rear hub motor and a half-twist throttle, with seven assist levels.
• About 52 miles at 12 mph on the throttle for a 180 lb rider on the 15 Ah pack, 70 on the 20 Ah, on level pavement.
• A 100 mm fork and 20 × 4.0 fat tires for broken pavement and gravel.
• A seat post with a 33 to 42-inch range and an adjustable stem.
• 85 lb and 29 inches wide, so it rolls through any door 29 inches or wider.

Red flags

Each one is about fit: who the M-81 is wrong for, and what to do instead.

• Wrong if you are taller than 5'9" and want a frame sized for you. The Eunorau MAX-CARGO 2.0, a longtail for riders 5'2" to 6'1", is $1,699 on our store.
• Wrong if you need a seat for the passenger, not a rack. Addmotor sells no passenger pad for it; the MAX-CARGO 2.0's review sets out a longtail built around carrying.
• Wrong if you ride in one of the 20 states whose words leave the M-81 outside their e-bike definition. The Eunorau G30-CARGO 2.0's 500 W counts as an e-bike in 47 states and DC, at $1,699.
• Wrong if your load tops 400 lb. The Graoopro, Addmotor's bigger cargo bike, lists 450 lb and a torque sensor, at $1,599 in Neptune Blue.
• Wrong if you want rear suspension. The M-81 has a fork only; email us and we will match your route to a bike on our shelf with a rear shock.
• Wrong if you climb 10% grades loaded and want to hold 12 mph. With 260 lb aboard, the model holds 10 mph on 10% and 8 on 12%; send us your steepest climb and your load, and we will price the ride on a bike on our shelf with more torque.

Buy it if / Buy something else if

Buy it if you want a cargo bike you can step through and stand astride with a load behind you: a 12-inch standover, a 25.8-inch rack built into the frame, a 400 lb payload, hydraulic discs and turn signals, and about 46 miles at 12 mph on the throttle with 260 lb aboard on the 15 Ah pack.

It asks for a rider inside Addmotor's window, 5'4" to 5'9", a load at or under 400 lb, a state whose e-bike definition takes in the M-81 and, for a child on the rack, a child seat that meets that state's words.

For $1,199 you get a 750 W rear hub motor, 90 N·m in Addmotor's figures, and a 48 V pack, a 100 mm fork, hydraulic discs on 180 mm rotors, seven Shimano gears, an integrated rear rack and turn signals. On Shop Pay's 12-month sample plan from our listing, that comes to $108.22 a month at 15% APR, $1,298.64 in all.

Buy something else if you are taller than 5'9", where the MAX-CARGO 2.0 is $1,699; if your state's words leave the M-81 outside its e-bike definition, where the G30-CARGO 2.0 is $1,699; or if you carry more than 400 lb, where the Graoopro is $1,599.

Our Addmotor brand profile sets the M-81 beside every other Addmotor on our shelf, and our e-bike reviews hub collects our other reviews.

Before you buy: the checklist

Run these ten checks before you spend $1,199; the first three decide who rides, who rides along, and where.

1. Find your state's row in the class table and its child rule in the passenger tables, then read its page in our law atlas.
2. Ask the agency behind each trail and park you plan to ride what it allows.
3. Add yourself, the rack and what you wear and keep the total at or under 400 lb.
4. Measure your inseam and read your row in the saddle table.
5. Choose a child seat or rack bag that mounts on a 6.5-inch-wide rack, and ask us about the rack's rating.
6. Ask us which pack ships, 15 Ah or 20 Ah, and read the range table for it.
7. Find your ride in the range tables, price the climbing, and keep 15% of the pack in reserve.
8. Pick where it will charge: indoors at 50 to 77 °F.
9. Plan the lock and the parking spot: 29 inches wide, 75 long.
10. Practice loaded starts and stops in an empty lot before your first ride with a child aboard.

Frequently asked questions

How far can the Addmotor Garootan M-81 go on one charge?

Addmotor prints 75 miles on assist level 1 in the Technical tab and "105+" in the stat strip. On the throttle over level pavement, the model gives a 180 lb rider about 52 miles at 12 mph on the 15 Ah pack and 70 on the 20 Ah, and every 1,000 feet of climbing at 10 mph takes another 142 to 183 Wh (the range tables).

Is the M-81 battery 15 Ah or 20 Ah?

Addmotor's page prints both: the Technical tab lists "48V/15Ah", and the feature copy, stat strip and its March 2026 images list 48 V 20 Ah. Every range figure on this page is given for both packs, and you can email us to confirm which ships with your order (the battery section).

How much weight can the Garootan M-81 carry?

400 lb in all, in Addmotor's Technical tab, counting you, everything on the rack and what you wear. Addmotor's posts of 2022 and 2023 printed 350 lb, and its October 13, 2023 post gives the rack alone "100 lbs"; today's tabs print no rack figure (carrying).

How much does the M-81 weigh?

85 lb, in Addmotor's Technical tab and its January 29, 2026 post. Addmotor's posts call the pack "removable", so it can come off before a lift; every range table carries the 85 lb (weight and size).

What height do you need to ride the Addmotor M-81?

Addmotor sizes it for riders 5'4" to 5'9". At 109% of inseam, the median rider in that window needs the saddle top 33.3 to 36.1 inches from the pedal, and the post runs 33 to 42 inches off the ground (the fit section).

Can you put a child seat on the Garootan M-81?

Addmotor's photographs show a child seat on the rack, and none comes with the bike. Pick one that mounts on a 6.5-inch rack and is rated for your child, and read your state's words first: eleven of the 29 jurisdictions inside the e-bike definition write in a young child (the passenger section).

Does the M-81 come with a passenger seat?

No. Asked whether the passenger pad in its photographs is sold, Addmotor answered on January 31, 2023: "we're sorry that we don't have that passenger pad for sale now." Three states, California, Massachusetts and Maryland, ask for a seat for every passenger (the passenger section).

How fast does the Garootan M-81 go?

Addmotor's Technical tab prints "20 Mph". With 260 lb aboard, the model holds 17 mph on a 4% grade and 11 on 8% on the throttle (the climbing table).

Can you ride the M-81 on the throttle without pedaling?

Yes: the Performance tab lists a "Variable Speed Control - 1/2 Twist Throttle", and the range tables print throttle-only miles for every speed. The motor's speed sensor also adds power once the cranks turn (the motor).

Does the M-81 have hydraulic brakes?

Yes: the Performance tab lists a "Hydraulic Disc Brake", and the feature copy adds "180mm rotors". The taillight carries a brake light and turn signals (brakes and lights).

Does the Garootan M-81 have suspension?

A front fork: the Performance tab lists an "Oil Spring Fork with 100mm of Travel". The rear has no shock, so the 20 × 4.0 tire takes the bumps behind you (fork and tires).

Is the Addmotor M-81 street legal, and what class is it?

Your state's words decide. Addmotor's 750 W and 20 mph sit inside the e-bike definitions of 29 jurisdictions on October 2, 2026, California's "does not exceed 750 watts" among them, and outside 20 (the class table). Send us your state and our reply will quote its rule.

Is the Garootan M-81 worth it?

For a rider 5'4" to 5'9" who wants a low step, a rack built into the frame and hydraulic brakes, it puts them together with a 400 lb payload for $1,199, or $108.22 a month over 12 months at 15% APR on Shop Pay's sample plan. Taller riders are better matched to the MAX-CARGO 2.0 (the verdict).

What warranty does the Garootan M-81 have?

When you buy from us, a fault comes to us first: we file the claim with Addmotor and stay on it until the bike is fixed. For Addmotor's written terms on your order, email us before checkout and we will have them confirmed in writing.

Limitations of this review

Nineteen points this review cannot settle, listed so you can weigh them.

1. We sell this bike. Give the red flags the same care as the green.
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 on this page.
3. Each range figure is one steady ride: one speed, one grade, no wind and no stops. Stops, starts, headwind, soft ground and a loaded rack started from rest cost more.
4. Bafang's figures stand in for Addmotor's motor. Addmotor gives its rating, its peak and its torque, but not its motor speeds or efficiency.
5. Addmotor prints two peaks for the motor: 1,400 W in its comparison image and 907 W in its 2023 and November 5, 2025 posts. The range model runs on the rated 750 W curve and the image's 90 N·m, so neither peak changes a table.
6. At light motor load the model has no measured check. Where your legs supply the larger share of the power, as in the steady-pedaling column, the answer rests on motor losses we could not check against a published motor map.
7. Addmotor's page prints two packs, 15 Ah in its Technical tab and a gallery title, 20 Ah in its feature copy, stat strip, two March 2026 images and every post naming the M-81. Both are computed; email us to confirm which ships.
8. Addmotor's page prints two controllers, 25 A in its Technical and feature copy and 20 A in its gallery; the range model does not use the controller's rating.
9. No measured range day on the M-81 was found. The routes read are listed at the end of the formula section.
10. 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.
11. The tire coefficient is the median of ten 26 × 4.00 fat tires at 12 psi, a different size from the M-81's 20 × 4.0, and the tire table brackets it.
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 and other published data.
13. Addmotor prints the saddle's height above the ground, not from the pedal. Without a bracket height or crank length, the saddle table gives the distance each height needs and leaves the last step to a tape measure on the bike and the knee range of the setup check.
14. Addmotor's size drawing did not hold to one scale, reproducing one other printed dimension within 3.5% at either of two scales, so no grip position is measured and no lean or hand load is computed; the formula subsection prints every comparison.
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, so your own inseam decides your row.
16. The battery's certification is as Addmotor describes it: "UL-certified" in the Technical tab and "UL-2271 Certified Battery" 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.
17. 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.
18. Colorways, prices and stock were read on October 2, 2026, and each can change, as can the Shop Pay terms and Addmotor's preorder dates.
19. The tire's name differs between Addmotor's records. The Performance tab lists Kenda GIGAS tires, and the sidewalls in Addmotor's photographs and drawing carry Kenda's KRUSADE name; email us and we will confirm which ships.

The bottom line

At $1,199, the Garootan M-81 puts a 750 W rear hub motor, a throttle and a 48 V pack on a step-through frame with a 12-inch standover, a 25.8-inch rack built in, a 100 mm fork, hydraulic disc brakes, turn signals and a 400 lb payload.

The model puts a 180 lb rider on level pavement at about 52 miles at 12 mph on the throttle with the 15 Ah pack and 70 with the 20 Ah, and 46 with 260 lb aboard on the 15 Ah; climbing costs 142 to 183 Wh per 1,000 feet at 10 mph on the throttle.

The right owners are riders 5'4" to 5'9" who want a low step and a rack behind them, keep the load at or under 400 lb, have a door 29 inches or wider to bring it through, and live where their state's e-bike definition takes in the M-81, with its passenger rule read before a child rides along.

On Shop Pay's twelve-month sample plan the bike costs $108.22 a month at 15% APR.

Three answers are worth having from us before checkout: which pack ships with your order, where the saddle should sit for your inseam, and what your state says about a child on the rack. Send us your height, your load and your state, and our reply will cover all three.

What each document behind this review supports.

T1 is the record itself, read from whoever issued it: a statute, a federal regulation or notice, the maker's own product page, drawing, question board and posts, and our own store record.

T2 is a party's own publication about its product or its measurements: the motor maker's workbook and research groups' and laboratories' published measurements.

Expiry conditions

Re-read this page if Addmotor changes the M-81's price, specification, motor, battery, range figure, top speed, weight, payload, saddle range, size drawing, colorways, preorder dates or question-board answers; or if the colorways, prices, stock or Shop Pay terms change on our store.

Re-read it too if a state changes its e-bike definition or its passenger rule, once North Carolina's December 1, 2026 change is read into our atlas, or if a recall is published naming Addmotor, the Garootan or the M-81. Verified October 2, 2026.
