Addmotor Landtan Review: 750 W Fat-Tire Trike

Fat-tire trike · 750 W rear-drive motor, 1,400 W peak, 90 N·m · cadence sensor and half-twist throttle · 48 V 15 Ah Samsung pack, 720 Wh · 15.6-inch standover · differential and parking brake · a disc brake on every wheel · 300 lb payload · 20 mph · $1,799 on October 5, 2026 · verified October 5, 2026

Quick Answer — Addmotor's Landtan is a $1,799 fat-tire trike for riders 5'1" to 5'9": a 15.6-inch step, a 750 W rear-drive motor, a differential and a 300 lb payload. On level pavement at 12 mph on the throttle, its 720 Wh pack computes to about 50 miles for a 180 lb rider, 41 with 300 lb aboard.

That window comes from Addmotor's Size & Fit table, where the saddle sets 29.1 to 37.4 inches off the ground. If you stand near either end of it, find your row in the saddle table before you order; how your state treats a 750 W trike is in the class section.

How we verified this Addmotor Landtan review

Every specification figure here was read on Addmotor's Landtan page, on its size drawing, on the trike's question board and in Addmotor's own posts, between September 28 and October 5, 2026. Price, colorways, stock and Shop Pay terms come from our store on October 5.

The range and fit sections compute from those published numbers and print every input beside the formula. It is a specification-verified review: Addmotor, a statute, our store, a study those two sections cite, or arithmetic printed here is the origin of every figure. Because we sell the Landtan, the red flags deserve the attention you give the green ones.

Addmotor's Landtan specification

The Landtan is built in a single size. Addmotor's Size & Fit table prints a single column, and its size drawing carries the same nine figures:

Addmotor's Size & Fit, Technical and Performance tabs, read September 28, 2026 and again on October 4, when every one of their 37 values was still in place; our price read October 5, 2026.

A 15.6-inch step and fat tires on all three wheels

The Landtan is a delta trike: one 20-inch wheel in front, two behind, and a frame that drops to 15.6 inches between the seat and the head tube. You walk through that low point instead of lifting a leg over a bar, sit on a sprung saddle, and steer with what Addmotor's handlebar image calls a "710mm U-handlebar".

Blue, the colorway on the cover, with the rear rack over the two back wheels.

All three tires are 20 × 4.0 inches, and Addmotor's tire banner labels them "All Terrain Fat Tire 20 x 4.0 Inches". The front one sits in an "ADDSHOX 20" Oil Spring Dual-Crown Suspension Fork", and the two at the back share a differential.

Behind the saddle, the pack rides under the rear rack with the taillight set into its back face, as Addmotor's battery image shows.

Addmotor also calls it the M-300. One of its posts is titled "Addmotor Landtan M-300 vs. Mooncool TK1", its size drawing's file is named m-300-size, and the product record carries SKU USCAB-835. Addmotor introduced it in a post of August 17, 2024: "Addmotor has released a new model: LANDTAN Fat Tire Electric Trike".

Every rider in that window gets the same frame. Asked on the trike's board whether a larger Landtan was coming, "Will you make a Plus sized version of the Landtan??", Addmotor answered on March 11, 2025: "Not for now." For a rider above 5'9", the Triketan M-330 is sized from 5'2" to 6'4" and costs $2,099 on our store.

Who the Landtan fits: 5'1" to 5'9" and a 15.6-inch step

The window is 5'1" to 5'9" in Addmotor's table, and across it the pedaling formula wants the saddle top 31.8 to 36.1 inches from the pedal for the median rider. Addmotor's 29.1 to 37.4 inches are measured from the ground, so the step that turns one figure into the other is a tape measure on the trike itself.

The formula sets the saddle 109% of your inseam from the pedal axle at the bottom of its stroke; Peveler and colleagues' 2005 comparison reports prior research finding that setting "may be optimum when examining economy". 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 calls for and leaves the last inch to you.

Three steps fit you to it:

1. Measure your inseam barefoot. Stand against a wall, raise a hardcover book between your legs as high as a saddle would sit, and measure from the floor to its spine.
2. Look up your height below for the saddle-top-to-pedal distance.
3. On the trike, turn one crank down in line with the seat post, measure from the saddle top to the middle of that pedal, and raise or lower the post to match your row.

Addmotor's size drawing over its photograph of the Blue Landtan. The formula subsection shows why nothing is measured on it.

How high does my saddle go?

Your row gives the distance from saddle top to pedal axle. The third column is the 109% formula at your height's median inseam; the last two are 106%, the low end of the range Ferrer-Roca and colleagues cite as recommended, and 110.4%, the top of the range they propose.

Built from the 6,068 bodies of the US Army's ANSUR II survey: inseams run from each height's 5th to its 95th percentile, and the three distances use the median inseam. Your own inseam moves your row, 1.09 inches of saddle for each inch of leg at 109%.

The 29.1 and 37.4 inches on Addmotor's drawing run to the ground, and the pedal axle sits above the ground even at the bottom of its stroke. So the lowest setting puts the saddle top less than 29.1 inches from the pedal, and the highest less than 37.4; by how much depends on a bracket height and crank length Addmotor does not print, which is why the tape-measure step settles it.

Can I step through it at a stop?

Yes, at every height in the survey. Every rider in the survey from 4'11" to 6'4" clears Addmotor's 15.6-inch standover barefoot.

The same bodies' barefoot inseams set against the 15.6-inch standover, with the median inseam shown for each height. At 5'1", 95 of every 100 riders clear the frame by 12.1 inches or more, and even at 4'11" by 11.2 inches or more.

With the frame that low, you stand over it with both feet flat while you load the rack or wait at a light, and you sit down by stepping back onto the saddle.

Will I lean forward to reach the bars?

The lean is not computed for the Landtan, because Addmotor publishes no grip position against the saddle. Its drawing prints a 13.4-inch reach and a 40.4 to 44.1-inch handlebar height, but no seat angle, and the drawing did not hold to one scale well enough to measure them (the formula subsection shows every comparison).

What Addmotor does publish is adjustment and shape. The handlebar's height runs over a 3.7-inch range, so you can raise the grips until your shoulders relax, and the bar is the swept "710mm U-handlebar" its image names, which brings the grips back toward the saddle.

How much weight goes through my hands?

Not computed here either, for the same reason. Your hand load follows from your lean, and the lean needs the grip's position, which Addmotor does not print. For scale, ten road racers on their brake hoods in Carahalios's 2015 laboratory study carried 15% of their weight on the bars, a stretched position an upright trike does not ask of you.

Set it by feel: raise the bar until your elbows stay slightly bent with your back upright, then ride a few blocks before changing it again. If your palms tingle on longer rides, Slane and colleagues measured padded gloves cutting palm pressure by 10 to 28% across 36 riders.

How do I set the saddle at home?

Raise the post until your leg is straight with your heel on the pedal at the bottom of the stroke. Pedaling on the ball of your foot then leaves a bend in the knee: in Peveler and colleagues' 2005 comparison this heel method put 70% of 19 trained cyclists inside a bend of 25 to 35 degrees, the range the cycling literature recommends for avoiding injury.

Then ride around the block and adjust the post in quarter-inch steps until the bend feels easy.

The fit arithmetic, step by step

One rule builds the saddle table: saddle top to pedal axle, at the bottom of the stroke, equals 1.09 times your inseam. At 5'8" with the median 32.6-inch inseam, the formula gives 35.6 inches; LeMond's rule, 88.3% of the inseam measured from the crank axle, gives the same rider 28.8 inches.

The saddle-table rule measures from the pedal and LeMond's from the crank axle, and only a crank length turns one into the other. Addmotor prints none, so each figure stands as its rule defines it.

Measured on, the drawing does not keep one scale. Scaled by the 46.1-inch wheelbase, read straight or carried onto the trike's centerline, or by the 70.9-inch length, it reproduces only one other printed dimension within 3.5% each time:

Points read on Addmotor's size drawing to ±3 px. Its own dimension arrows imply 14.2 to 17.6 pixels per inch where the wheels imply 16.7 to 17.2, so no seat angle, crank or grip position is taken from it.

The motor: 750 W at the rear, 90 N·m, a half-twist throttle

The motor is a 750 W unit at the back of the trike, in Addmotor's rating. The Technical tab reads "750W Rear-Mounted Motor", the stat strip "Rear-Drive Motor 750W", and the comparison image adds "(1400W Peak, 90Nm Torque)"; its callout image repeats "1400W Peak Motor Power".

The launch post of August 17, 2024 explains how the power reaches the ground: "The motor connects to the rear differential, which then provides the right amount of power to each wheel." The range model reads the motor as driving that axle apart from your chain, so the gear you pick sets your cadence rather than the motor's load.

The assist follows your pedaling, and the throttle works without it. The Performance tab lists a "Cadence Sensor" with "7 Level Pedal Assist", and the "Variable Speed Control - 1/2 Twist Throttle" moves the trike with your feet still. Addmotor's comparison post of January 20, 2025 calls the same part a "speed sensor"; neither name describes a torque sensor, which reads how hard you push, and for that the Triketan M-330 carries one, at $2,099.

Addmotor prints "Up to 20 MPH" on the Technical tab, and the callout image reads "Top Speed 20Mph". An "Addmotor 25A Controller" runs the system, and the "Addmotor 5-Inch LCD Display" is part of what the comparison image calls "EB 2.0—Horn, Turn Signals, 7-Speed Settings, Smart Control".

Seven Shimano gears carry your pedaling: "Shimano 7-Speed", a "Shimano 7 Speed Rear Derailleur" and a "KMC Stainless Chain". Drop to the low gears before a stop, so the next start shares the push between your legs and the motor.

The 720 Wh Samsung pack under the rack, and charging it

Fifteen amp-hours at 48 volts stores 720 watt-hours. The Technical tab lists a "48V*15 Ah Battery", the stat strip calls it a "Samsung Battery", and Addmotor's callout image prints "Battery Capacity 720Wh".

The pack under the rear rack, with the taillight built into it, in Addmotor's image.

A full charge from low takes about seven to eight hours. Addmotor's battery post of October 23, 2024 says of the Landtan's pack: "The charging time for this battery pack is around 7-8 hours". The arithmetic agrees: 15 amp-hours at the charger's 2 amps is 7.5 hours from empty, and a top-up from 20 to 80%, nine amp-hours, about 4.5.

The charger is the Technical tab's "48V*2.0A 5 Pins Short Plug US Standard DC Charger"; at its 2 amps, the times above follow from the pack's 15 amp-hours.

Three numbers from Addmotor cover the pack's care:

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

Range: how far a charge takes the Landtan

On level pavement with the throttle alone, a full pack carries a 180 lb rider about 50 miles at 12 mph and 29 at 20 mph; loaded to the full 300 lb, the 12 mph ride runs about 41. Add easy pedaling at 12 mph and the 180 lb rider's charge stretches to about 100 miles; hold 10 mph up a steady 8% grade on the throttle and it shrinks to about 8.

To read your own ride off the tables:

1. Start in the first two tables: your usual pace is the row, your pedaling the column.
2. Add the climbing: every 1,000 feet at 10 mph on grades of 4 to 10% takes 160 to 215 Wh on the throttle, or 144 to 191 Wh with easy pedaling (the hills table).
3. Then correct for the weight you carry and the air temperature, and budget 85% of the pack.

Every row is one steady ride, computed from Addmotor's figures, a comparable motor's published data, drum measurements of ten fat tires and a cycling-power model validated on an open road; the formula subsection works one ride from end to end.

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

On the throttle, the pace you hold sets the miles: 63 at 8 mph, 50 at 12 and 29 at 20. The power the air takes grows with the cube of speed, so riding at 20 mph instead of 12 multiplies that share about 4.6 times.

Each row assumes 180 lb aboard, the throttle alone, level pavement and 77 °F air. The right-hand column leaves 15% in the pack, the upper end of Addmotor's "10%-15%" recharge advice.

Pedal and every row stretches. Easy pedaling is 75 W here and steady pedaling 150 W; with the motor off, those efforts alone would move a 180 lb rider on this trike at about 8.5 and 12.7 mph on the flat, a fair guide to which column you can hold.

180 lb aboard, level pavement, a full pack. "Legs alone" marks a pace your 150 W holds by itself. In the 100-mile and 117-mile cells your legs do most of the work, and those figures lean on the motor's losses at light load, the least-checked part of the model (Limitations item 5).

Pick the row for your pace and the column for your effort; the assist level only decides how the work is shared between you and the motor.

Does shifting gears save battery?

Only through what your legs add. Your chain and the motor reach the axle by separate paths, so at a given speed and grade the pack spends less only when you push harder:

Watt-hours from the pack per mile, 180 lb aboard in 77 °F air. At 12 mph on the flat, 150 W from your legs holds the pace without the motor, so its draw drops to zero.

Choose the gear that keeps your cadence easy to sustain: a gear you can turn is the one that lets your legs carry part of the load instead of leaving all of it to the pack.

What does a climb cost the pack?

Climbing 1,000 feet at 10 mph on a 4 to 10% grade costs the pack 160 to 215 Wh more than covering the same ground on the flat with the throttle, or 144 to 191 Wh with easy pedaling. Raising rider and trike takes 51 to 69% of the throttle figure, and heat in the motor and pack takes the rest.

Rider and trike together weigh 292 lb, 180 of it you and 112 the trike, and lifting that 1,000 feet takes 110 Wh at the wheels. On an 8% grade at 10 mph, throttle only, each 1,000 feet costs the pack 193 Wh; spent on climbing alone, all 720 Wh would lift that load about 3,700 feet.

Every row is ridden at 10 mph with 180 lb aboard; the last column adds 75 W of easy pedaling. The model gives nothing back for descents, so read these rows as the cost of the climb alone.

On a grade, a heavier load costs speed first. The motor's torque sets the fastest steady pace it holds on each grade, and the full 300 lb holds a slower one:

The fastest steady speed the model's motor holds on each grade with 180 lb aboard or Addmotor's full 300 lb payload, on the throttle except in the last column. Steady state only, with no run-up into the grade, and the motor's torque capped at the 90 N·m of Addmotor's comparison image.

Past 10% at 10 mph, the throttle alone asks more than the model's rated 750 W: at 12% your easy pedaling brings it back inside, at about 5 miles to the charge, and at 15% neither does, so slow down and shift down.

Price a hilly day in two parts: the level miles, then the climbing. Twenty level miles at 12 mph on the throttle use about 288 Wh; add 1,000 feet of 8% climbing at about 193 Wh and the day needs about 481 Wh, 79% of the 612 Wh in 85% of the pack.

How far does a full 300 lb load go?

Extra weight barely moves the level-ground figures and moves the climbing ones a great deal. Mass loads the tires and the grade but not the air, so the difference between a light and a heavy load grows with the slope.

The first column counts you and everything you carry; the model adds the trike's own 112 lb, and every cell is throttle only. The bottom row is Addmotor's 300 lb payload; up 8% at 10 mph that load asks more than the rated 750 W in the model, so pedal or slow to the 9.7 mph the climbing table gives.

Going from 180 lb to the full 300 lb trims the 12 mph ride from 50 miles to 41, about a fifth, and the 15 mph ride from 41 to 35. Addmotor's October 14, 2024 comparison lists the Landtan's "Max Weight Capacity" as "300 lbs", so plan with yourself inside that figure.

The trike's own weight moves the answer by two miles or less. Addmotor's answer on its board gives 112 lb with the battery, and the Technical tab gives 90 lb; both run through the model:

180 lb aboard. Every other table on this page uses the 112 lb, the figure Addmotor gives with the pack named.

How much range does cold weather take away?

Expect a little over a fifth less at freezing. The 12 mph throttle ride that runs 50 miles at 77 °F runs about 39 at 32 °F and about 36 at 14 °F.

180 lb aboard on level ground, with the cells assumed to sit at the air's temperature. Each row's central figure is the energy McMaster University's measured LG HG2 cell gave at a 0.5C discharge in its runs at 77, 50, 32 and 14 °F, with the rows between interpolated; since Addmotor names Samsung cells, Samsung data sheets set the brackets.

A bracket spans the lowest capacity any of those Samsung sheets lists at that temperature, for discharges of one to four times capacity per hour (25R and 30Q at 32 °F, 35E at 14 °F), up to the highest energy Casado and colleagues recorded in 2025 at a gentler rate.

Three losses stack up in cold air. At 32 °F the cells return about 89% of their 77 °F energy, 80 to 93% depending on the source, and by the U.S. Standard Atmosphere's gas law the air is about 9% denser.

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

In winter, charge indoors. Addmotor's cold-weather post says to "Always charge your battery indoors at room temperature because cold weather can harm the battery cell if you charge it at lower temperatures".

Does the tire or the riding position change the range?

The tire matters most on level ground. Bicycle Rolling Resistance ran ten 26 × 4.00 fat tires on its drum at 12 psi, 18 mph and a 94 lb load, and they drew 23.2 to 42.1 W. No 20-inch fat tire is on that list, so the model uses the ten's median coefficient, 0.0105, and brackets it with the lowest and the highest.

Full-pack miles for a 180 lb load on level ground. The highest belongs to Kenda's Juggernaut Pro, whose own measurement page prints 0.01262.

Keep the tires at the pressure printed on their sidewalls, since every coefficient here was measured on an inflated tire. The air term uses the drag area Tengattini and Bigazzi measured on 37 upright cruiser riders, 0.640 m², the posture this trike puts you in; their 0.603 m² for 90 mountain-bike riders would lift the 15 mph throttle ride from 41 miles to 42.

Addmotor's 65 miles, as a steady ride

Addmotor's one range figure lines up with a steady pace in the model. The Technical tab prints "Up to 65 Miles (PAS1)", and Addmotor's comparison post of January 20, 2025 repeats "Up to 65 Miles Riding Range".

The steady level-ground speed at which the model spends all 720 Wh over 65 miles with 180 lb aboard, 11.1 Wh a mile, with 75 W of easy or 150 W of steady pedaling in the last two columns.

Read that way, Addmotor's 65 miles describes an unhurried ride with your legs in it, about 14.7 mph with 75 W from you; on the throttle alone the same distance needs a pace near 7 mph. Ease a throttle ride up to 12 mph and the model's 50 miles sits below it.

Budget 85% of your row, because Addmotor's advice is to recharge "when it has a 10%-15% charge left": on the throttle at 12 mph, that is 42 of the 50 miles.

If you want the pack to last, ride inside the 20–80% band. Those 432 Wh, 60% of the pack, are the window Addmotor's maintenance guide describes with "keep your battery charge between 20% and 80% for the best lifespan":

Miles inside the band, 180 lb aboard, level ground. The 8 mph easy-pedaling cell reads "legs alone": 75 W on its own moves this rider at about 8.5 mph on level ground.

The formula behind the range tables

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

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

P is the power at the wheels and v the road speed; m is the combined mass of trike, rider and load, g is gravity and θ the slope's angle; Crr is the tires' rolling resistance, ρ the density of the air and CdA the rider's drag area. Inside the brackets, the first term covers tires and slope and the second, with ρ, the air. Between the wheels and the pack there are three steps:

1. Your legs deliver 97.7% of their effort to the wheels through the chain, the efficiency Martin and colleagues measured, and the motor makes up the difference.
2. The motor follows a published curve from a comparable unit, Bafang's RM G0H0, whose 2021 OEM workbook lists 510 rpm unloaded, 426 rpm at rated load at 48 V, and "≥ 80" percent efficiency. Starting from Addmotor's published 20 mph, the model holds Bafang's curve at the Landtan's 48 V and 750 W and sets the unloaded speed at 21.8 mph, the pace at which a 180 lb rider on the throttle just reaches 20 mph on the flat.
3. The pack turns a little of its energy into heat, at the rate Arango, Lopez and Ceren measured on a 48 V pack.

Dividing the pack's watts by the speed in mph gives watt-hours per mile, and miles = 720 Wh × the share of pack energy usable at that temperature ÷ watt-hours per mile.

A worked example, from the tires back to the cells: 180 lb aboard, 12 mph on the throttle, level pavement. Together rider and trike are 132.4 kg; holding 12 mph takes 131.9 W at the wheels, 73.4 W against rolling resistance and 58.5 W against the air.

On 24-inch-tall 20 × 4.0 tires, the rear wheels turn 168 times a minute at that speed. Fitted to Bafang's published figures, the motor model has 1.50 N·m of torque per amp, a 0.405 Ω winding and a 0.83 A no-load current; this ride asks it for 7.5 N·m on 5.8 A, at 79% efficiency, a point below its rated 80% because the load is light.

Counting the pack's own losses, the cells deliver 172.9 W, which at 12 mph is 14.40 Wh a mile: 720 ÷ 14.40 comes to about 50.0 miles, or 42.5 with 15% kept back.

Before computing anything, the model reproduced two published checks:

The first row is Appendix I of Martin and colleagues (8.36 m/s, a 90 kg system, a 0.3% grade); the second is the RM G0H0's rated point in Bafang's workbook. A motor 82% efficient, above Bafang's 80% floor, would lift the 12 mph throttle figure from 50 miles to 55 (Limitations item 4).

Nothing published gives a measured Landtan ride with the rider's weight and speed stated, so the model has no ride of this trike to be checked against. Addmotor's four answers on its Landtan board and its 17 posts with Landtan figures were read on October 4, 2026; the range figures they give state no speed or rider weight.

Carrying: a rear rack, no baskets in the box, 300 lb in all

The baskets are extras on the Landtan. Addmotor's product FAQ answers plainly: "The Landtan electric trike comes with a battery. And the front basket and rear basket are not included. A front basket cannot be installed on this trike."

So the rear rack over the two back wheels is where a load goes. Before you order, email us what you plan to carry and we will confirm with Addmotor which rear basket fits that rack.

The 300 lb counts you. The Technical tab prints a "300 LBS" payload, and Addmotor's comparison of October 14, 2024 lists the Landtan's "Max Weight Capacity" as "300 lbs"; plan with your own weight inside that figure, as the weight table does.

A trailer carries more. Addmotor's product page says "An Addmotor trailer can be added to increase cargo space and transport flexibility". Email us before you order one and we will confirm the hitch for your trike.

Stopping, parking and turning: three discs, a parking brake, a differential

A disc brake on every wheel, a parking brake on the lever, and a differential between the rear wheels. The Performance tab lists "Mechanical Disc Brakes On Each Wheel" and answers "Yes" on its Parking Brake and Differential rows; Addmotor's comparison image sums up the set as "Triple Mechanical Disc + Parking Brake".

One caliper and rotor for each wheel, the rotors stamped 180, in Addmotor's image.

The parking-brake button on the lever, in Addmotor's close-up.

Set the parking brake before you load the rack on a slope, and before you climb on or off a trike parked on a grade.

Take corners slowly, the way Addmotor asks. Its post on the Freetan for seniors, of July 15, 2026, puts the rule for every trike in one line: "As with any electric trike, riders should reduce speed before turns and avoid abrupt steering inputs." For a first ride, its post for new trike riders suggests a flat route with "no obstacles or tight turns".

The lights run off the main battery. The Performance tab lists a "48V DC, 40 Lux LED Headlight, IPX6 Waterproof" and a "48V DC LED Light with Turn Signals" at the back, "Powered by the main battery".

The rear light's five modes, as Addmotor's image labels them.

Fork, tires and weather

Suspension is up front: an "ADDSHOX 20" Oil Spring Dual-Crown Suspension Fork". The three 20 × 4.0 tires do the rest, on what the Performance tab calls an "Addmotor Aluminum Rim" at each wheel.

Addmotor's close-up of the ADDSHOX fork above the front wheel.

Off the pavement, the model has no numbers to give. Addmotor's tire banner names three surfaces, "Roadway", "Sand" and "Rocky Terrain", while every range table above is level pavement or a paved grade. Send us your route and we will price the paved miles and climbs in it.

Keep the pack out of standing water and away from pressure washers. The headlight is rated "IPX6 Waterproof", and Addmotor's maintenance guide warns: "Never submerge the battery in water or use high-pressure sprays." In winter, cold air also costs range, as the cold table shows, so plan shorter rides.

112 pounds with the pack, 32.7 inches wide, 70.9 long

Addmotor gives three weights, and this page plans on the one that names the battery. On October 17, 2025, asked "How much does the trike weigh?", Addmotor answered: "The weight is 112 LBS (Include Battery)". The Technical tab prints "90 LBS", and two posts, of October 14, 2024 and January 20, 2025, give 88.2 lb; none of those three says whether the pack is in.

Measure the doorway before the delivery. The trike is 32.7 inches across and 70.9 inches long in the Size & Fit table, and Addmotor's post of November 13, 2024 gives the same width as "rear track width: 83 cm". A door narrower than that sends it to a garage, a shed or a wide side entry, and at 112 lb a ground-level route from the curb matters more than the stairs.

For a car, use a trike carrier rated for at least 112 lb and 32.7 inches of width; the trike's frame does not fold.

It arrives mostly built. Addmotor's stat strip says "Pre-Assembled 80%", and its product FAQ says the trike "comes 85% pre-assembled. Please follow the video to complete the final step." That video, posted June 21, 2025, covers "setting up the front wheel and saddle to installing the battery, lights, and handlebar system".

The manual ships in the box. Asked on October 16, 2025 "Is there a user manual for this etrike?", Addmotor answered: "The trike comes with the user manual, it was packed with the trike in box."

The Mercer fit test

The Mercers, the same seven people in every review we publish, are held up to each machine so the fit answers compare from page to page. Every verdict rests on Addmotor's published window, standover or payload, or on the fit tables computed from them.

Three of the household, Ruth, Dana and Maya, fall inside the 5'1" to 5'9" window; Frank, Jack and Cole are taller. For the three taller riders, the Triketan M-330, sized from 5'2" to 6'4", is the Addmotor trike on our shelf to read next.

Has it been recalled?

No. On October 4, 2026, no recall in the Consumer Product Safety Commission's recall data named Addmotor, the Landtan, the M-300 or USCAB-835.

The search covered the recall title, product-name and manufacturer fields for Addmotor, ADDMOTOR, Add Motor, Addmotor Tech, Motan and Addrider, and 19 Addmotor model families with the Landtan among them. Every field of a 623-record corpus of bicycle, e-bike, battery and scooter recalls was then read for the brand, those families and the model code, written M-300, M300 or M 300.

Run on makers with known recalls, the same queries found 1 for Ancheer, 54 for Specialized and 24 for Trek, so the search does find a recall where one exists.

Across the full list of 10,027 recalls, no record names Addmotor, the Landtan or USCAB-835. Two records carry "M300", and both are laptops: a Toshiba Portege M300 battery recall and a Compaq Armada M300 adapter recall.

Class and road rules: where a 750 W trike lands

What your state's definition says decides before the trike does. Addmotor's page lists 750 W, a throttle and 20 mph, and those are the three places the federal definition draws a line.

Under 15 U.S.C. § 2085(b), a low-speed electric bicycle is "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 a paved level surface, is "less than 20 mph".

Statute and trike both read on October 4, 2026, from § 2085(b) and Addmotor's Landtan page.

Each of Addmotor's figures sits on a federal line the statute writes as "less than". The statute measures speed on motor power alone with a 170-pound rider, which a maker's published top speed does not report, so no specification table settles how the trike would measure.

California draws its line inclusively. In California Vehicle Code § 312.5(a), read September 28, 2026, an electric bicycle has "an electric motor that does not exceed 750 watts of power", its class 2 motor stops helping "when the bicycle reaches the speed of 20 miles per hour", and § 231 gives a bicycle "one or more wheels" and states "An electric bicycle is a bicycle."

State by state, across the 50 and DC, the wording decides. Run through each definition's watt wording, throttle rule, top speed, wheel count and Pennsylvania's weight limit on October 4, 2026, Addmotor's published figures sit inside 25 jurisdictions' e-bike definitions and outside 23; Connecticut's leaves a three-wheeler open, and Alaska and Kentucky have no e-bike definition.

Each state's definition as our state law atlas records it, screened October 4, 2026. In nineteen of the 23, the motor must be "less than" or "fewer than" 750 watts, a line a 750 W motor does not pass; New Jersey's turns on its throttle rule; Montana and Rhode Island define an e-bike on two wheels, as Alabama and New Jersey also do; and Pennsylvania's takes in "A vehicle weighing not more than 100 pounds".

Pennsylvania is the row Addmotor's weights decide. 75 Pa.C.S. § 102 defines a pedalcycle with electric assist as "A vehicle weighing not more than 100 pounds with two or three wheels more than 11 inches in diameter". At the 112 lb Addmotor gives with the battery, the Landtan sits outside; at the Technical tab's 90 lb, a screen run the same day puts Pennsylvania inside, the only row to change.

This page counts Pennsylvania outside. If you ride there, write to us before you order and we will ask Addmotor, in writing, for the weight of the trike as delivered.

Connecticut's row moved on October 1, 2026, when Public Act 26-24 § 26 rewrote the definition to a motor of "not more than seven hundred fifty watts", and § 14-1 defines no "bicycle", which leaves the wheel count unsettled there; for Connecticut, email us and we will confirm how a three-wheeler is treated.

North Carolina rewrites its definition on December 1, 2026, into three classes. The new text in Session Law 2026-46 still covers a bicycle "with two or three wheels" and "an electric motor of no more than 750" watts, and a class 2 motor there "ceases to assist once the bicycle reaches a speed of 20 miles per hour"; the Landtan's row is inside before the change and after it.

Outside a state's e-bike definition, the trike is still something on that state's roads, a moped, a motor vehicle or another class, and the state sets what that requires of you. Each state's answer is in our 50-state e-bike law atlas, with our California e-bike law page going furthest for one state.

Trails and public land: whose rule applies

Off the street, whoever manages the land decides where the Landtan may go, fat tires or not. On federal land, the Bureau of Land Management sets its own 750 W definition and the Forest Service decides e-bike access district by district.

BLM's 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.)", and the Landtan's published 750 W sits within it.

Where a field office has decided e-bikes ride as bicycles, its off-road vehicle rules relax, on one condition in the regulation's words: "the motor is not exclusively propelling the e-bike for an extended period of time".

A long throttle stretch runs into that condition. With your feet still on the throttle, the motor is propelling the trike alone; where the exception falls away, 43 CFR 8341.1 limits an off-road vehicle to land designated "open to off-road vehicle use".

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

For every row, the land manager's own document is the final word.

The penalty for breaking BLM's rules, under 43 CFR 8340.0-7, is "a fine of not more than $1,000" or imprisonment "for not longer than 12 months", or both. Our public-land e-bike guide walks through every agency's version.

Green flags / Red flags

Green flags

• A 15.6-inch step-through that every rider in the survey from 4'11" to 6'4" clears barefoot.
• A differential, a disc on each wheel and a parking brake for corners, stops and loading on a slope.
• 20 × 4.0 tires on all three wheels, with an ADDSHOX dual-crown fork in front.
• A 720 Wh Samsung pack that carries a 180 lb rider about 50 miles on level pavement at 12 mph on the throttle, and about 100 with easy pedaling.
• 90 N·m, a half-twist throttle, seven assist levels and seven Shimano gears on a 750 W rear-drive motor.
• A pack tucked under the rear rack, with the taillight built into it and about seven to eight hours to charge from low, in Addmotor's words.
• Turn signals, a horn and a 40-lux headlight, all running off the main battery.
• $1,799 against the $2,599 regular price, with Shop Pay plans from $162.37 a month.

Red flags

Every item below is about fit: the rider the Landtan does not suit, and the next step for that rider.

• Wrong if you are taller than 5'9". Addmotor sizes the Landtan to 5'9" and has no larger version planned; the Triketan M-330, sized from 5'2" to 6'4", is $2,099 on our store.
• Wrong if you want baskets in the box. The Landtan ships with none, and a front one cannot be fitted; the Triketan M-330 comes with both, at $2,099.
• Wrong if you want assist that answers to how hard you push. The Landtan's sensor follows your pedaling; the Triketan M-330 carries a torque sensor.
• Wrong if the frame itself must fold. It does not; the Citytri E-310 folds, from $1,599, and its Standard is sized for the same 5'1" to 5'9".
• Wrong if you and your load top 300 lb. The Grandtan M-340 carries 450 lb in all, from $2,199.
• Wrong if you want more than about 50 level miles at 12 mph on the throttle. The Triketan M-330's 960 Wh pack computes to about 67 at that pace in its review.
• Wrong if you want to sit back with the pedals out front. The Arisetan II M-360 is Addmotor's semi-recumbent, from $2,399.
• Wrong if you want suspension at the back as well. The Grandtan X adds a rear shock, at $2,799.
• Wrong if you climb past 10% and want the throttle to do it alone. Above 10% at 10 mph the model needs your pedaling too; for steep ground, our Grandtan Turbo review runs the numbers on a mid-drive at $3,299.
• Wrong if your door is under 32.7 inches wide and there is no garage or wide entry to use. Email us the door's width and we will match it to a trike we sell.
• Wrong if two adults want to ride together. One seat; the M-380 tandem seats two, from $3,899.

Buy it if / Buy something else if

Buy it if you stand 5'1" to 5'9", want to walk through a low frame instead of swinging a leg over, and want fat tires under you on every wheel: a differential and a parking brake for corners and slopes, a throttle for the days you would rather not pedal, and about 50 miles at 12 mph on the throttle for a 180 lb rider.

It asks for a rider inside Addmotor's window, a load that keeps you and your cargo at 300 lb or under, a rack for that cargo instead of baskets, a ground-level space behind a door at least 32.7 inches wide, and somewhere indoors to charge.

For $1,799, $800 below the $2,599 regular price, you get a 750 W rear-drive motor with 90 N·m in Addmotor's figures and a 720 Wh Samsung pack, a differential, a disc on each wheel, a parking brake, seven Shimano gears, a sprung saddle and turn signals. Over 12 months, Shop Pay's sample plan on our listing is $162.37 a month at 15% APR, $1,948.44 in all.

Buy something else if you are taller than 5'9" or want baskets and a torque sensor, where the Triketan M-330 is $2,099; if the frame must fold, where the Citytri E-310 is from $1,599; or if your load passes 300 lb, where the Grandtan M-340 is from $2,199.

Our Addmotor brand profile sets the Landtan beside Addmotor's other trikes and bikes on our shelf, and our e-bike reviews hub gathers our reviews of trikes and bikes from other makers.

Before you buy: the checklist

Ten checks before the $1,799 order; the first three decide who may ride it and where.

1. Start with your state's row in the class table, then its page in our law atlas.
2. Ask each park or trail you plan to use for its rule; the land manager decides.
3. Measure your height and inseam and find your row in the saddle table; above 5'9", read the Triketan M-330 review.
4. Add yourself and the load and keep the total at 300 lb or under.
5. Plan the cargo: the rear rack, a rear basket we confirm with Addmotor, or a trailer.
6. Measure the doorway and the parking space: 32.7 inches wide and 70.9 inches long.
7. Plan the transport: a trike carrier rated for 112 lb and 32.7 inches.
8. Read your ride in the range tables, add the climbing, and leave 15% of the pack unused.
9. Pick where it will charge: indoors, at 50 to 77 °F, with about seven to eight hours from low.
10. Practice in an open field or a parking lot before you ride in traffic, as Addmotor's post for new trike riders suggests.

Buying it from us

Why buy the Landtan from Redtail

Our listing priced the Landtan at $1,799 in Blue and Red on October 5, 2026, with $2,599 shown as the regular price, and both colorways were in stock. Our part starts when you order.

Red, the second of the two colorways.

Each colorway has its own button.

A link adds that colorway to your cart at our October 5, 2026 price.

To return it for a change of mind, the trike must still be sealed in its factory packaging and you must ask within 72 hours of delivery; our refund policy then takes it back less a 15% restocking fee and return shipping, and a canceled order carries a 3% transaction fee. Ask us the fit, load and route questions first, before any of that comes up.

Frequently asked questions

How far can the Addmotor Landtan go on one charge?

Addmotor's figure is "Up to 65 Miles (PAS1)". On the throttle over level pavement, the model gives a 180 lb rider about 50 miles at 12 mph and 29 at 20 mph, and about 41 at 12 mph with the full 300 lb aboard; every 1,000 feet of climbing at 10 mph takes another 160 to 215 Wh (the range tables).

How much does the Addmotor Landtan weigh?

112 lb with the battery, in Addmotor's answer of October 17, 2025: "The weight is 112 LBS (Include Battery)". The Technical tab prints 90 lb and two of Addmotor's posts 88.2 lb, without saying whether the pack is in; this page plans on 112 (weight and size).

What is the top speed of the Addmotor Landtan?

Addmotor publishes "Up to 20 MPH" on the Technical tab, and its callout image reads "Top Speed 20Mph". At that pace on the throttle over level ground, a 180 lb rider's charge lasts about 29 miles (speed and range).

Is the Landtan good for short riders?

It is sized for them: Addmotor's window runs from 5'1" to 5'9", the frame's low point is 15.6 inches, and the formula puts the saddle top 31.8 inches from the pedal for a 5'1" rider with the median inseam, 29.2 inches. Every rider in the survey from 4'11" up clears the step barefoot; find your row in the saddle table.

Do e-trikes tip over easily?

Addmotor's own advice for every trike is to slow before the corner: "riders should reduce speed before turns and avoid abrupt steering inputs." For a first ride, its new-rider post suggests a route with "no obstacles or tight turns", and practice somewhere open before you meet traffic (stopping, parking and turning).

Does the Landtan have a differential?

Yes. The Performance tab answers "Yes" on its Differential row, and Addmotor's launch post of August 17, 2024 describes it: "The motor connects to the rear differential, which then provides the right amount of power to each wheel." (the motor).

Does the Landtan come with baskets?

No. Addmotor's product FAQ says "the front basket and rear basket are not included. A front basket cannot be installed on this trike." The rear rack takes your load, and we will confirm a rear basket that fits it before you order (carrying).

How long does the Landtan's battery take to charge?

About seven to eight hours from low. Addmotor's battery post of October 23, 2024 says "The charging time for this battery pack is around 7-8 hours", and a top-up from 20 to 80% runs about 4.5 hours on the 2 A charger; charge it indoors at room temperature (the battery).

Is the Landtan street legal, and what class is it?

Your state's words decide. On October 4, 2026, Addmotor's 750 W and 20 mph sit inside the e-bike definitions of 25 jurisdictions, California's "does not exceed 750 watts" among them, and outside 23; Pennsylvania turns on which of Addmotor's weights applies (the class table). Tell us where you ride and we will send that state's rule.

Can the Landtan go uphill?

Yes, and the model prices it: with 180 lb aboard the motor holds about 12.9 mph up an 8% grade, and a full charge covers about 8 miles of that climb at 10 mph on the throttle. Each 1,000 feet of climbing costs 160 to 215 Wh (the hills tables).

Will Medicare pay for an electric trike?

Not under Medicare's national list for durable medical equipment. The Centers for Medicare & Medicaid Services' reference list, NCD 280.1, answers exercise equipment with "Deny - not primarily medical in nature", and its covered items name no bicycle or tricycle. Shop Pay spreads the $1,799 over 12 months (buying it from us).

Is the Landtan a good trike for seniors?

It is built around an easy mount: a 15.6-inch step, a sprung saddle, a swept bar whose height adjusts, a differential and a parking brake. Addmotor's advice to every trike rider is to "reduce speed before turns", and your clinician is the right person for any balance or joint question (the fit section).

Where are Addmotor trikes made?

Addmotor's About page places the company's warehouse and showroom in El Monte, California, and says it "has its own factory for designing and manufacturing products". Our Addmotor profile covers the company and compares its trikes and bikes.

Is there a larger Landtan for taller riders?

Not for now, in Addmotor's words: asked on March 11, 2025 about "a Plus sized version of the Landtan", it answered "Not for now." Above 5'9", the Triketan M-330 is sized to 6'4" (who the Landtan fits).

Does the Landtan come assembled?

Mostly. Addmotor's stat strip says "Pre-Assembled 80%" and its product FAQ "85% pre-assembled", and its assembly video covers the front wheel, saddle, battery, lights and handlebar. Asked about a manual on October 16, 2025, Addmotor answered that it "was packed with the trike in box" (weight and size).

How do you transport an electric trike like the Landtan?

On a trike carrier rated for its 112 lb with the pack and its 32.7-inch width, since the frame does not fold. At 70.9 inches long, measure the vehicle or trailer bed first (weight and size).

Limitations of this review

What this review cannot settle, in twenty-three numbered points.

1. This is our product. Read the red flags with the weight you give the green.
2. Every figure is specification-verified: Addmotor's published documents, statutes, our store record, the research the range and fit sections cite, or arithmetic printed here.
3. A range row is a single steady ride at one speed on one grade, without wind or stops; real rides with starts, headwinds and soft ground use more.
4. A Bafang motor's published curve stands in for Addmotor's. Addmotor prints the rating, peak and torque but no motor speeds or gearing to the differential; at 82% efficiency instead of Bafang's 80% floor, the 12 mph throttle ride would run 55 miles, not 50.
5. Light motor loads are the least-checked part of the model. When your legs carry most of the work, as in the 15 mph steady-pedaling column, the answer depends on motor losses no published motor map was available to confirm.
6. The unloaded motor speed is set so that a 180 lb rider on the throttle just reaches Addmotor's 20 mph; a faster motor held back by a speed limiter would draw a little differently close to 20 mph.
7. Addmotor prints the weight three ways: 112 lb with the battery on its board, 90 lb on the Technical tab and 88.2 lb in two posts. The tables use 112; at 90 lb the 12 mph throttle ride gains two miles, and Pennsylvania's row in the class table turns on which applies.
8. No ride on the Landtan with its distance, rider weight and speed recorded was found; what was read is listed at the close of the formula section.
9. The tables spend the full 720 Wh. Addmotor does not say how much of the pack its battery management lets you use; on one pedelec measured on a test bench, researchers at KIT found 75% in use over a standard range test.
10. The rolling-resistance figure comes from 26-inch fat tires, the median of ten at 12 psi, not from the Landtan's 20 × 4.0; the tire table shows how far the answer moves.
11. One laboratory cell anchors the cold table. With no Samsung cell model named by Addmotor, the central line follows McMaster University's LG HG2 measurements, and Samsung and other published data set the brackets.
12. Nothing is measured on the size drawing. At three scales it reproduced only one other printed dimension within 3.5%, so the saddle table gives the formula's distance from the pedal and leaves the ground-to-pedal step to a tape measure.
13. The lean and the hand load are not computed. Addmotor publishes no seat angle or grip position and the drawing could not supply them, so the cockpit and hand subsections give Addmotor's adjustment range instead of a figure.
14. The saddle distances are a starting setting: each is the 109% formula at the median inseam for that height, and the heel check on your own trike settles the last quarter inch.
15. The bodies behind the fit tables are soldiers: ANSUR II's 6,068, aged 17 to 58 and measured from 2010 to 2012, not a sample of the US public, so your own inseam should pick your row.
16. Addmotor names the sensor two ways: "Cadence Sensor" on the Performance tab and "speed sensor" in its January 20, 2025 comparison. Ask us before you order and we will confirm with Addmotor which one your trike carries.
17. Some older posts print other figures than today's page: "400W peak power" in the post of October 14, 2024 against 1,400 W in the comparison and callout images, and "24 x 4 inches" tires in the post of August 31, 2024 against 20 × 4.0 on the page and drawing. The model uses the 750 W rating and 90 N·m, not the peak, and the page's 20 × 4.0 tire.
18. Addmotor states the pre-assembly two ways, 80% on the stat strip and 85% in its product FAQ; both are printed.
19. The class table reads each state's definition as our law atlas records it, screened October 4, 2026; a state can change its words, as Connecticut did on October 1, 2026 and North Carolina will on December 1, and three-wheeler wording outside the definition section was not read for every state.
20. The Mercer verdicts read the formula and Addmotor's window, never a fitting on the trike; the three members above 5'9" are routed by the window.
21. Colorways, prices and stock were read on October 5, 2026, during a sale on Addmotor's own site with no end date printed; if its prices change, ours follow, and so do the Shop Pay terms.
22. The box contents are Addmotor's FAQ answer: a battery, and no baskets. Ask us before ordering and we will put in writing what comes with an order placed here.
23. The cornering advice is Addmotor's general line for its trikes, from its post on the Freetan, and no rollover or cornering figure for the Landtan itself was found.

The bottom line

At $1,799, the Landtan puts a 750 W rear-drive motor with 90 N·m and a 720 Wh Samsung pack under a step-through frame with a 15.6-inch step, 20 × 4.0 tires on all three wheels, a differential, a disc on each wheel, a parking brake and a 300 lb payload.

The model puts a 180 lb rider on level pavement at about 50 miles at 12 mph on the throttle and 100 with easy pedaling, and a full 300 lb load at about 41; climbing costs 160 to 215 Wh per 1,000 feet at 10 mph on the throttle.

The right owner stands 5'1" to 5'9", wants to walk through a low frame onto fat tires, carries a load on a rack within 300 lb, keeps the trike at ground level behind a door of 32.7 inches or more, and rides where their state's words take in a 750 W machine.

Spread over Shop Pay's 12-month sample plan, it is $162.37 a month at 15% APR.

Before checkout, get two answers from us: where your inseam puts the saddle, and what your state calls a 750 W trike. Send us your height, your roads and your trails, and our reply will give the saddle distance and the rule for each.
