Longtail cargo e-bike · 750 W rear hub motor, torque sensor, half-twist throttle · one 48 V 20 Ah pack (960 Wh) with the bike, a second as an add-on · 18-inch standover · 32 × 7-inch rear rack · mechanical disc brakes · 80 mm fork · 24 × 2.0 front and 20 × 3.0 rear tires · 450 lb payload · 72 lb · 20 mph · $1,499 on October 8, 2026 · verified October 8, 2026

Quick Answer — Addmotor's Graoopro is a $1,499 longtail cargo e-bike: a 750 W rear hub motor, a torque sensor, a 32-inch rack and a 450 lb payload, with one 960 Wh pack. At 12 mph on the throttle over level pavement, a 180 lb rider computes to about 83 miles; Addmotor prints 105+ on assist level 1.

Addmotor builds it for a second pack too, and with both aboard and the second pack's 13.2 lb counted, the same ride computes to about 164 miles. Addmotor sizes the bike for riders 5'4" to 6'2", and whether a child may ride the rack is your state's call, quoted in the passenger section.

Addmotor's Graoopro specification

One longtail frame, four colorways, one pack in the box and room for a second.

Addmotor's Size & Fit tab, read October 8, 2026. It prints the seat's top setting as "42" with no unit, beside "33''" for the lowest, and the rider window as "5'4"-6 '2"".

Quoted on October 8, 2026 from the Technical and Performance tabs of Addmotor's Graoopro page, with its feature copy and stat graphic. Two rows quote the page against itself: its copy gives the motor's peak as 1,000 W and its stat graphic as 1,300 W, and the motor section says what the range model takes from each.

A 78-inch longtail with a 32-inch rack

The Graoopro is a longtail: a step-through frame stretched behind the saddle so a 32-inch rack runs over the rear wheel. Addmotor titles its page "Addmotor GRAOOPRO Dual Battery Electric Cargo Bike | Utility Bike", and its January 29, 2026 post lists the frame as "Reinforced Longtail Aluminum Alloy".

Neptune Blue, the colorway in stock on October 8, 2026, in Addmotor's studio photograph.

The frame runs 78 inches on a 52-inch wheelbase, with an 18-inch step in front of the saddle and a wooden footboard on the deck, and a center-mount kickstand holds it upright for loading. Addmotor's copy puts the packs "below the plane of the rear rack, giving you more room for what you're carrying."

The two wheels are different sizes on purpose in Addmotor's table: a 24 × 2.0 tire steers at the front, and a 20 × 3.0 tire carries the motor and the load at the back. The rack sits 27 inches off the floor, the height to measure a child seat or a crate against before you lift one on.

Addmotor launched the Graoopro in October 2023, and two of its printed figures have moved since. Its October 13, 2023 comparison gave the front tire as "24''X2.5''", where today's tab reads "24''X2.0''". Its posts of 2023 and 2024 put the motor's peak at 1,000 W, its sale posts of 2025 at 1,300 W, and the page now prints both.

The 450 lb payload has held since the October 16, 2023 post, which splits it as "300+150 lbs". When you compare listings or shop a used one, a 2.5-inch front tire is Addmotor's 2023 figure; every figure in this review is from the current page unless it carries a date.

In Addmotor's parts pages the Graoopro is the G-800. Its April 25, 2024 rear-rack post names the "Graoopro G-800", and the spare pack's page lists "G-800" among the bikes it fits, the code to quote when you order a part.

Does the Graoopro fit you? Saddle 33 to 42 inches

Addmotor sizes the Graoopro for riders 5'4" to 6'2", and at 109% of inseam the median rider of each of those heights in the Army's ANSUR II survey needs the saddle top 33.3 to 39.3 inches above the pedal. Addmotor lists the saddle 33 to 42 inches above the ground, so the open question is how far below it the pedal sits.

The formula is the Hamley and Thomas rule, the saddle 109% of your inseam above the pedal axle at the bottom of the stroke, one of the methods Peveler and colleagues compared in trained cyclists in 2005. It is a starting point, and the heel check below finishes the job.

Three steps fit you to it:

1. Measure your inseam barefoot. Back against a wall, press a hardcover book up between your legs and read the tape from the floor to the book's top edge.
2. Read your height's row in the saddle table for the distance from the saddle top to the pedal axle.
3. Finish with the heel check in the setup subsection: one crank pointing down along the seat tube, your heel on that pedal, your leg straight.

Addmotor's size drawing from the Graoopro's Size & Fit tab, laid over its studio photograph of the Orange bike. Why the page takes no measurement from it is set out in the formula subsection.

How high does my saddle go?

Find your row, then set the saddle top that far above the pedal axle at the bottom of its stroke. The middle column applies 109% to your height's median inseam. The last two use 106%, the low end of the range Ferrer-Roca and colleagues cite, and 110.4%, the top of the range they propose.

Computed on 6,068 bodies the US Army measured for ANSUR II. The inseam column runs from the 5th to the 95th percentile at each height, and the three distance columns use that height's median inseam; at 109%, every inch of your own inseam adds 1.09 inches to the figure.

Addmotor's 33 and 42 inches are measured to the ground, and the formula to the pedal. The pedal's lowest point sits some inches above the floor, so the saddle at its lowest setting is less than 33 inches from the pedal and at its highest less than 42. The bracket height and crank length that settle by how much are not on Addmotor's page; a tape measure on the delivered bike settles it.

Can I step through it at a stop?

Yes: every height in the survey clears the 18-inch standover barefoot. Down at 4'11", the shortest height in the survey, 95 riders in 100 still clear it by 8.8 inches or more.

Each height's median barefoot inseam against the 18 inches Addmotor lists, drawn at the step-through deck in its size drawing; the same bodies as the saddle table.

The low deck is what lets you put both feet down with a load behind you instead of lifting a leg over a top tube, and the center-mount kickstand holds the bike while you load it.

Will I lean forward to reach the bars?

No lean figure for the Graoopro appears here: where its grips sit against the saddle is not published. Addmotor prints an 18-inch reach, drawn from the seat post to the head tube, but no seat angle and no handlebar height, and its drawing did not hold one scale (the formula subsection shows every comparison).

What Addmotor describes is adjustment: its October 5, 2023 post says "the handlebar is also adjustable and can be easily adjusted in terms of height and angle to suit the rider's sitting posture."

How much weight goes through my hands?

Not computed either: the load on your hands follows from your lean, and the lean needs the grip position. For scale, ten road racers riding on their brake hoods carried 15% of their body weight on the bars in Carahalios's 2015 laboratory study, riding a road bike's racing position.

Set the bar by feel: shoulders loose and elbows slightly bent, then ride a few blocks before you change anything else.

How do I set the saddle at home?

Start from your row's height, and let your heel confirm it. With one crank pointing straight down along the seat tube and your heel on that pedal, your leg should be straight; riding on the ball of your foot then leaves the knee bent 25 to 35 degrees, the range Peveler, Pounders and Bishop worked to.

Do it with the bike on its center-mount kickstand and the rack empty, since a loaded rack makes the bike harder to hold while you work the seat post.

The fit arithmetic, step by step

A single rule builds the saddle table: the top of the saddle sits 1.09 times your inseam above the pedal axle when that pedal is at its lowest. A 5'8" rider with the median 32.6-inch inseam gets 35.6 inches from it, and LeMond's rule, which takes 88.3% of inseam from the crank axle, puts the same rider at 28.8 inches.

Each rule starts from a different point, and turning one into the other takes the crank length, which Addmotor does not print, so both are given as written.

Read as a scale drawing, the sketch gives no single scale that fits its own labels. Scaled by its own 52-inch wheelbase line, it reproduces none of Addmotor's other five printed dimensions within 3.5%; by the 78-inch length line, one; by the 18-inch standover line, one:

Each line read on Addmotor's drawing as the run of dark pixels it draws, end marker to end marker, to ±6 px. The two saddles in it sit 44 px apart, about 3.0 inches at the wheelbase scale, against the 9-inch range it labels, so the drawing shows the two settings without measuring them, and no grip position or seat angle is taken from it.

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

The motor is a 750 W unit in the rear hub, by Addmotor's rating. The Technical tab lists a "750W Rear Brushless Gear Motor", the feature copy a "48V*750W Rear-Mounted Motor" with "the Max Motor Torque at 80 Nm", and Addmotor's September 28, 2025 sale post a "750W rear brushless hub motor".

For the peak, the page prints two figures. Its copy reads "Peak Motor Watts at 1,000W", as Addmotor's posts of October 16, 2023 and May 28, 2024 do, while its stat graphic reads "Peak Motor 1300W", as its sale posts of September 28, 2025 and November 5, 2025 do. The range tables are built on the rated 750 W curve and the 80 N·m, so they stand whichever peak is right.

The pedal sensor is a torque sensor in Addmotor's words. The Performance tab names a "Torque Sensor", and the feature copy adds: "With 36 torque sensing points, the PAS initiates intervention when the pedal is shifted by 20°." Addmotor's February 29, 2024 post on sensors lists "Graoopro e-bikes" among its models with torque sensors and explains the idea: "The harder the rider pedals, the more power is delivered by the electric motor".

The half-twist throttle moves the bike with your feet at rest, and Addmotor's October 16, 2023 post counts "7 available pedal-assist levels". Your pedaling runs through a Shimano 7-speed; the hub motor turns the wheel apart from your chain, so the gear you pick sets your cadence and not the motor's. How a 750 W, 20 mph bike is classed is in the class section.

One pack or two: the 960 Wh battery and its second pack

One 48 V, 20 Ah pack, 960 watt-hours, comes with the $1,499 bike, and a second of the same size is an add-on. The Technical tab reads "Available with Single and Dual EB2.0 48V*20AH (21700-5000mah)", and Addmotor's buy box, read October 8, 2026, offers the second pack as the "20Ah Samsung UL-Certified Battery".

Addmotor's FAQ lists what comes with each of its bikes: "a tool kit, a manual, a pair of pedals, a battery and a charger". Our listing sells the bike with one pack too; for the two-pack build, email us before you order and we will quote it that day.

The two-pack build in Addmotor's photograph: both packs sit behind the seat tube, under the rack, with a child seat on top.

The spare pack's own page gives its weight and its fit. Addmotor's listing for the pack names "G-800" among the models it fits, and Addmotor answered there on October 17, 2025: "The battery weighs 6 kg (about 13.2 lbs). Its dimensions are roughly 38 x 8 x 12 cm."

How the two packs share the work is not set out for the Graoopro. Addmotor's May 28, 2025 post on dual-battery bikes describes the type in general, "wiring two high-capacity batteries in parallel (or, in some cases, offering a removable range extender)", and says of this bike that it "offers a dual-battery option that delivers up to 210 miles per charge".

The range tables add the second pack's 960 Wh to the first, the energy either arrangement stores.

The charger Addmotor lists is a 48 V, 2-amp unit, so a 20 Ah pack takes about 10 hours from empty by the arithmetic of amp-hours over amps, and two packs on the one charger about 20. Addmotor's battery-health post advises recharging "when it has a 10%-15% charge left", and its maintenance guide charging "at room temperature (between 10 and 25 degrees Celsius)", which is 50 to 77 °F.

Range: how far a charge takes the Graoopro

On level pavement with the throttle alone, one 180 lb rider computes to about 83 miles at 12 mph and 45 at 20 mph on one pack, and to about 164 at 12 mph on two, the second pack's 13.2 lb counted. Add easy pedaling at 12 mph and one pack reaches 210 miles; hold a steady 8% climb at 10 mph on the throttle and it falls to about 13.

Your own ride converts to miles in three steps:

1. Look up your pace and effort in the first two tables, then use the load table if a child or cargo rides on the rack.
2. Price each 1,000 feet of climbing at 10 mph: 129 to 159 Wh on 4 to 10% grades on the throttle, 125 to 147 Wh with easy pedaling (the hills table).
3. Correct the miles with the cold-weather table, and count 85% of the pack as usable.

Each row is one steady ride. The inputs are Addmotor's own figures, a comparable hub motor's published data, a field study of 273 everyday riders' commuter tires and a cycling-power model validated on an open road; the formula subsection works one ride through by hand.

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

At a steady pace on one pack: 112 miles at 8 mph, 83 at 12, 45 at 20. The air's share of the work grows with the cube of speed, so the last few miles an hour cost the most.

Throttle only, a 180 lb rider, level pavement, 77 °F air. The 15% columns keep back the top of Addmotor's "10%-15%" recharge advice; the two-pack column runs at the table's 72 lb, and with the second pack's 13.2 lb counted each figure comes out about 2% lower (the bike-weight table).

Pedaling adds to every row. In these tables easy pedaling means 75 W and steady pedaling 150 W, and with the motor switched off those two efforts move a 180 lb rider on the Graoopro along level ground at about 10.2 and 14.1 mph.

Level pavement, a 180 lb rider, a single pack. Where a cell reads "legs alone", your 150 W holds that speed without the motor. The 210- and 270-mile cells depend most on how the motor behaves at light load, where the model has the least checking behind it (Limitations item 6).

Pick any assist level: it divides the work between you and the motor, while your speed and your effort decide the miles.

Does shifting gears save battery?

Only through your legs, because the hub motor turns the wheel apart from your chain. 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. On level ground at 12 mph, steady pedaling at 150 W moves the bike with no draw on the pack at all.

Pick the gear for a cadence you can hold, and shift down before you stop, so a loaded rack starts again with your legs helping.

What does a climb cost the pack?

Every 1,000 feet you climb at 10 mph adds 129 to 159 Wh over the same distance on the flat, on 4 to 10% grades with the throttle working alone, or 125 to 147 Wh with easy pedaling. Raising rider and bike accounts for 60 to 74% of the throttle figure, and the motor and pack lose the remainder as heat.

Put a 180 lb rider on the 72 lb bike and 252 lb goes up the hill; 1,000 feet of height costs about 95 Wh at the wheel. On an 8% grade at 10 mph on the throttle the pack pays 148 Wh for each 1,000 feet, which means a full 960 Wh would carry that load up about 6,500 feet and leave none for level riding.

Each row is 10 mph, a 180 lb rider and a single pack, with 75 W of easy pedaling added in the last column. Descents give nothing back in the model, so these figures err low.

A loaded rack slows the climb. How fast the motor can climb a grade depends on its torque, and every pound of bike and load brings that speed down:

Top steady speed on each grade for the model's motor with a 180 lb rider, with 260 lb of rider and cargo, and with Addmotor's full 450 lb, on the throttle except in the third column. "Past the model's motor" means the grade asks for more torque than its 80 N·m at any speed. A second pack changes the miles, not these speeds.

For a day with hills, add two numbers: the level miles and the climbing. Twenty level miles at 12 mph on the throttle use about 230 Wh and 1,000 feet of 8% grade about 148 Wh more; together that is about 378 Wh, 46% of the 816 Wh one pack offers with 15% held back.

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

On the flat, loading up from 180 lb to Addmotor's full 450 lb takes the 12 mph ride from 83 miles to 59; up a grade, far more. Extra weight makes the tires and the grade work harder but leaves the air's share unchanged, so the gap grows as the road steepens.

The weight column counts you, anyone or anything on the rack and what you wear; the model adds the bike's own 72 lb, and every cell is one pack on the throttle. At 400 lb and above, holding 10 mph up 8% needs more torque than the model's motor has; the climbing table shows it settling at 8 mph with 450 lb.

Add 80 lb of child, seat and groceries to a 180 lb rider and the 12 mph ride drops from 83 miles to 74, the 15 mph ride from 66 to 60. At Addmotor's full 450 lb the same rides give 59 and 50 miles; with two packs aboard each flat figure about doubles, a little less for the second pack's weight:

One 180 lb rider, miles per pack. The 85 lb column adds the 13.2 lb Addmotor gives for its spare pack: the two-pack build, or the one-pack build if the table's 72 lb leaves the pack out, which the table does not say.

How much range does cold weather take away?

Expect roughly a fifth fewer miles at 32 °F. On one pack, the 12 mph throttle ride that gives 83 miles at 77 °F gives about 67 at 32 °F and about 61 at 14 °F.

A single pack and a 180 lb rider on level ground, with the cells at the temperature of the air. The middle figure in each row comes from the LG HG2 cell McMaster University measured at a 0.5C discharge, interpolated between its test temperatures; Addmotor names Samsung 21700 cells of 5,000 mAh without a model number, so the brackets come from other cells' published data.

Each bracket's low end is the smallest capacity a Samsung data sheet lists at that temperature for discharges of one to four capacities an hour (25R and 30Q at 32 °F, 35E at 14 °F); its high end is the most energy Casado and colleagues recorded at a gentler rate.

Cold air costs miles three ways at once: the cells return less of their energy, the U.S. Standard Atmosphere's gas law makes the air denser, and the tires stiffen. For the tires, the model adds 0.5% to rolling resistance for every °F under 77 °F, a rate between Rothhämel's fit for a 42 mm tire and Bicycle Rolling Resistance's road-tire average, and stops adding below 41 °F.

Charge the pack indoors in cold months: Addmotor's maintenance guide puts charging at 50 to 77 °F.

Does the tire or the riding position change the range?

At 12 mph on level ground the tires take about 43% of the wheel's work and the air the rest. Addmotor names the tires by size and tread, "Reflective Thin Tires", and no drum or field test of them was found, so the model takes the average Tengattini and Bigazzi measured on 273 everyday riders' commuter tires, a coefficient of 0.0074, and brackets it.

Miles from a full single pack with a 180 lb rider on level ground. The slick row is the same study's average for its slick-tire riders, and the high row adds one standard deviation to the commuter average.

These tables cover pavement only, not grass, gravel or sand. For the air, the same study measured 0.640 m² of drag area across 37 upright cruiser riders, the value used here; its 0.603 m² for mountain-bike riders adds 2 to 3 miles, 83 to 86 at 12 mph and 66 to 68 at 15.

Addmotor's 105 and 210 miles, as steady rides

Read as steady rides, Addmotor's distances are unhurried ones. The Technical tab prints "Up to 105+ Miles Per Charge with PAS 1 (Estimate Miles)" for one pack and 210+ for two, and 105 miles on 960 Wh is 9.1 Wh a mile. One undated Addmotor post, a list of five fat-tire bikes, gives one pack "up to 85 miles per charge", close to the model's 83 at 12 mph on the throttle.

For a 180 lb rider on level ground, the steady speed at which the model uses 9.1 Wh a mile. Two packs and 210 miles ask the same 9.1 Wh a mile, so the same speeds apply, a touch lower for the second pack's weight.

Read that way, 105 miles on one pack is a ride at about 9 mph on the throttle alone, or about 15 mph with 75 W from your legs. Hold 12 mph on the throttle and the model's 83 miles land below Addmotor's figure; pedal easily at 15 mph and its 108 land just above it.

Riding between 20% and 80% charge is easier on the cells. The band holds 60% of the pack, and it is the range Addmotor's maintenance guide has in mind with "keep your battery charge between 20% and 80% for the best lifespan":

Miles within the band from a single pack, 576 of its 960 Wh, with a 180 lb rider on level ground. The easy-pedaling cells at 8 and 10 mph say "legs alone": 75 W with no motor already carries this rider at about 10.2 mph.

The formula behind the range tables

Every table starts from the wheel: the power it needs to hold a steady speed in still air, from the model Martin and colleagues validated on an open road in 1998:

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

Here P is the wheel's power and v the road speed; m is the mass of bike, rider and load together, g is gravity and θ the slope's angle; Crr stands for the tires' rolling resistance, ρ for air density and CdA for the rider's drag area. Between that wheel power and the pack's watt-hours lie three stages:

1. Your pedaling loses 2.3% in the chain on its way to the wheel, the 97.7% efficiency Martin and colleagues measured, and the motor makes up whatever is left.
2. The motor borrows the curve of a comparable hub motor whose figures are published: Bafang's 2021 OEM workbook gives its RM G0H0 510 rpm with no load and 426 rpm at rated load on 48 V, at "≥ 80" percent efficiency. Scaled to Addmotor's 48 V and 750 W, the curve is set to an unloaded 21.6 mph, the speed at which a 180 lb rider on the throttle just makes Addmotor's 20 mph on level ground.
3. The pack warms as it delivers current; the loss follows 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 960 Wh, or 1,920 Wh with the optional second pack, × the share usable at that temperature ÷ watt-hours per mile.

A worked ride, wheel to pack: a 180 lb rider at 12 mph on the throttle, on level pavement, with one pack. Rider and bike come to 114.3 kg, and the wheel needs 103.0 W: 44.5 W for rolling resistance and 58.5 W for the air.

The 22-inch rear wheel spins at 184 rpm at that speed. The motor model, fitted to Bafang's figures, carries a torque constant of 1.39 N·m per amp, a 0.405 Ω winding and 0.83 A of no-load current; the ride calls for 5.4 N·m at 4.7 A, delivered at 77% efficiency, short of the rated 80% because the load is light.

Adding the pack's internal losses, the cells give up 138.0 W; spread over 12 miles an hour that is 11.50 Wh a mile, and 960 ÷ 11.50 comes to about 83.5 miles, or 71.0 once the 15% reserve is set aside.

Two published benchmarks, reproduced before any figure was computed:

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

The record holds no measured Graoopro ride with the rider's weight and speed stated, so the model stands without an independent check. Addmotor's question board for the bike held no questions on October 8, 2026, and the range figures in the 23 Addmotor posts that give figures for the bike state no speed or rider weight.

Carrying: 450 lb in all, 150 lb on the rack

Addmotor's 450 lb covers you, what you wear and everything on the rack. The Technical tab prints a payload of "450 LBS", and Addmotor's October 16, 2023 post splits it: "300+150 lbs, or in total, 450 lbs".

For the rack alone, Addmotor's launch post gives 150 lb. Its October 5, 2023 post describes "a long rear rack with a max load capacity of 150 lbs". Today's tabs print the rack's dimensions, 32 inches by 7 and 27 inches off the floor, without a rating, so email us and we will confirm it with Addmotor before you load near it.

Addmotor's launch press release gave a higher figure. Its release of October 5, 2023 introduced the bike "with a max load capacity of 500 lbs", split as "300 lbs + 200 lbs"; the tab and the Addmotor posts that give the bike a payload print 450, and every table here uses 450. If your load falls between the two, email us and we will put the question to Addmotor in writing before you order.

A child on a padded rear seat behind the rider, both in helmets, in Addmotor's banner image; whether a child may ride there is each state's call (the passenger section).

Addmotor writes the bike for one or two children. Its October 16, 2023 post says the cargo area takes "an additional attachable seat, making it suitable for transporting one or two kids", and its April 25, 2024 rear-rack post says its seat pads "make space for a child or another passenger".

Addmotor makes a passenger seat pad for the rack, the "Electric Bike Mini Passenger Seat Pad"; ask us about one before you order. A child seat is yours to choose: check its mounting against the rack's 7-inch width and its rating against your child.

Groceries on the rack in Addmotor's image, the rider helmeted.

The passenger section quotes what each state's code says about carrying a child, and the load table what the weight does to your miles.

Mechanical disc brakes, lights and turn signals

Mechanical discs front and rear, in Addmotor's tabs. The Performance tab lists a "Mechanical Disc Brake", as the table in its January 29, 2026 post does; the prose of that post speaks of "Hydraulic disc brakes", so if the brake type decides your order, ask us first and we will confirm the build with Addmotor.

Start braking earlier with a load aboard. With a child or cargo on the rack, keep both hands on the levers, slow down sooner than you would riding alone, and practice a few loaded stops in an empty lot before your first errand.

The headlight and taillight are part of the build. The Performance tab gives the headlight "a brightness of 40 lumens, a visible distance of 200m, and a 180° side view" and the taillight "left and right turn signals, danger light, flashlight, brake light"; the feature copy calls it "a versatile 5-in-1 taillight".

An 80 mm fork, a 24-inch front and a 20-inch rear

A fork up front, the tires behind. The Performance tab lists an "Oil Spring Fork with 80mm of Travel"; the rear has no shock, so the 3-inch rear tire and the saddle take the bumps behind you, and so does anyone riding the rack.

The fork, marked ADDSHOX, in Addmotor's close-up.

Addmotor calls the tires "Reflective Thin Tires", and its copy says they "Enhance your safety and visibility on the road, even in low-light conditions, with tires featuring reflective strips." Its October 13, 2023 comparison listed them as "Durable Thin Tires" and its January 29, 2026 post as "Urban Tires"; the range tables price pavement only.

72 pounds, 27 inches wide, 78 inches long

Make room for 72 lb, 27 inches across and 78 inches nose to tail, the weight from the Technical tab and the width and length from the Size & Fit tab. The tab does not say whether the 72 lb includes the pack, and a second pack adds 13.2 lb by Addmotor's own answer.

The center-mount kickstand, which Addmotor's copy puts to use "when parking or loading/unloading cargo."

The wooden footboard, a platform Addmotor says is for riders "to place their feet while cruising".

Before the box arrives, measure your doorway and where the bike will park. At 27 inches wide the bike needs a doorway wider than that, and 78 inches of floor along a wall to park; a ground-level spot spares you lifting 72 lb, more with a child seat fitted.

The Mercer fit test

The Mercers, the seven people we hold every bike against, are measured here against the window, standover, saddle range and payload Addmotor publishes, and against the fit tables built on them.

Every adult Mercer and Cole fit inside Addmotor's window; Ivy's row is the one that turns on law, not on the frame. Dana can carry her on the rack inside the 450 lb budget, but whether Ivy may ride there, and in what seat, is set by the state they ride in.

Has it been recalled?

No. The Consumer Product Safety Commission's recall data, searched on October 8, 2026, held no recall that names Addmotor, the Graoopro or its G-800 code.

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, Graoopro among them, and read every field of a 623-record corpus of CPSC recalls for the brand and its model codes, G-800 included.

That empty result means something only because the same search finds real recalls: run alongside it, Ancheer returned 1, Specialized 54 and Trek 24.

Is it UL certified?

Addmotor's page names UL 2271 for the pack. Its stat strip reads "UL Certification UL 2271", the spare pack is sold as the "20Ah Samsung UL-Certified Battery", and the taillight row begins "UL certificate".

Where a building manager, an insurer or a city asks for a certificate, email us and we will request Addmotor's documents in writing.

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

Your state's words decide how the Graoopro is classed. Addmotor's page gives the two numbers the federal definition turns on, 750 W and 20 mph, and a throttle that can run the bike on the motor alone, the condition of the statute's speed test.

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.)", and its top speed on the motor alone, carrying a 170-pound rider on a paved level surface, must be "less than 20 mph".

The statute column was read in § 2085(b) and the bike column on Addmotor's page, both on October 8, 2026.

The statute's lines are drawn at "less than", and Addmotor's 750 W and 20 mph each land on one. Addmotor's 20 mph is its own figure, not a result of the statute's motor-only test with a 170-pound rider, so a spec table cannot place the bike on that test.

California's line takes in 750 W: California Vehicle Code § 312.5(a) defines an electric bicycle as having "an electric motor that does not exceed 750 watts of power".

We screened all 50 states and DC on October 8, 2026 for watt wording, throttle rule, top speed, wheel count and Pennsylvania's weight limit: on Addmotor's published figures, the Graoopro falls inside 29 jurisdictions' e-bike definitions and outside 20. Alaska and Kentucky publish no e-bike definition.

The screen read each state's definition as our state law atlas records it on October 8, 2026. Of the 20 outside, 19 set the motor limit at "less than" or "fewer than" 750 watts, which a 750 W motor does not meet. New Jersey's verdict rests on its throttle rule. Pennsylvania's "not more than 100 pounds" takes in the Graoopro's 72 lb, and 85.2 lb with a second pack.

Two rows inside the definition hold wording the screen leaves untested. South Carolina writes "a top motor-powered speed of less than twenty miles an hour when operated by a rider weighing one hundred seventy pounds", which repeats the federal line, and Connecticut's "not more than seven hundred fifty watts" came into force on October 1, 2026 under Public Act 26-24 § 26.

On December 1, 2026 North Carolina's definition splits into three classes. Session Law 2026-46 keeps "no more than 750 watts" and gives class 2 a motor that "may propel the bicycle without pedaling but ceases to assist once the bicycle reaches a speed of 20 miles per hour", which leaves the Graoopro's row inside.

A state whose definition leaves the Graoopro out still classes the bike somehow, whether as a moped, a motor vehicle or something else. Our 50-state e-bike law atlas holds each state's answer, with a separate page for California.

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

Of the 29 jurisdictions whose e-bike definitions take in the Graoopro, 23 tie the number of riders to what the bike is designed or equipped to carry, 3 ask for a seat for each passenger, and 3 set no count in the sections read; 11 write in how a young child may ride. Each quote below was checked against the statute's text in its deposit on October 8, 2026.

Addmotor makes a passenger seat pad for the rack, and its posts describe the cargo area as fit for "one or two kids" on an attachable seat. How a state's words read a pad or a child seat on a rack is that state's question, and the tables below give each one's own wording.

Each rule was read in the jurisdiction's official text between August and October 2, 2026, and each quote re-checked against its deposit on October 8; Georgia's and New Mexico's were read in a FindLaw copy of the code. New Mexico, in the sections read, counts an e-bike as a "bicycle" only for its helmet act, which leaves open whether its passenger rule applies to the Graoopro; its row gives the rule as written.

Eleven of the 29 say how a young child may ride, and most point to a child seat or carrier. The words differ by state:

From the census of the 29 jurisdictions, re-checked October 8, 2026. Connecticut's subsection covers riding "upon a roadway, path or part of roadway set aside for exclusive use of bicycles, electric bicycles or electric foot scooters", while its child exception names no electric bicycle.

Three states ask for a seat for every passenger. California's § 21204(b) seats a passenger "upon or astride a separate seat attached thereto". Massachusetts asks for "a permanent and regular seat attached to the bicycle" (c. 85, § 11B). In Maryland, § 21-1203(b) wants "a seat securely attached to it for each passenger".

In North Carolina, § 20-171.9 asks for a helmet on anyone under 16 and a restraining seat for a passenger who weighs less than 40 pounds or stands under 40 inches. They attach to a "Bicycle" that § 20-171.8 defines as "a human-powered vehicle", so whether they reach an e-bike is an open question either way; following them is the careful course.

Where those rules apply, a breach "shall be an infraction": the parent or guardian found responsible may be ordered to pay "a civil fine of up to ten dollars ($10.00)", which the court may waive on a first conviction once a helmet or restraining seat has been obtained (§ 20-171.9(d)–(e)).

Trails and public land: whose rule applies

Once you leave the pavement, whoever manages the land sets where the Graoopro may ride. The Bureau of Land Management defines an e-bike with its own 750 W limit on its land, while each Forest Service district decides for itself.

43 CFR 8340.0-5 sets the BLM's test for an e-bike: "a two- or three-wheeled cycle with fully operable pedals and an electric motor of not more than 750 watts (1 h.p.)". At 750 W, the Graoopro meets it.

A BLM field office can choose to manage e-bikes as bicycles, provided "the motor is not exclusively propelling the e-bike for an extended period of time". Where it does not apply, 43 CFR 8341.1 keeps off-road vehicles to land designated "open to off-road vehicle use".

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

Each row is settled by the land manager's own document, and our public-land e-bike guide sets out each agency's rules.

Green flags / Red flags

Green flags

• A 450 lb payload and a 32-inch rack for $1,499.
• A torque sensor, in Addmotor's words, and a half-twist throttle on a 750 W rear hub motor.
• One 960 Wh pack, with room for a second: about 83 miles at 12 mph on the throttle for a 180 lb rider on one, about 164 on two, on level pavement.
• An 18-inch step-through that every rider in the survey from 4'11" to 6'4" clears.
• A rider window of 5'4" to 6'2" that takes in every adult Mercer.
• A wooden footboard and a center-mount kickstand for loading.
• An 80 mm fork and reflective-stripe tires, with turn signals and a brake light on the taillight.

Red flags

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

• Wrong if you are shorter than 5'4". The Eunorau G30-CARGO 2.0 is sized from 5'1" and the MAX-CARGO 2.0 from 5'2", both $1,699 on our store.
• Wrong if you ride in one of the 20 states whose words leave the Graoopro outside their e-bike definition. The G30-CARGO 2.0's 500 W sits inside 19 of those 20, and inside 48 jurisdictions in all, by the same screen on October 8, 2026.
• Wrong if you want hydraulic brakes and fat tires. The Garootan M-81 has both, with a 400 lb payload, at $1,099.
• Wrong if your load tops 450 lb. Email us your load and what it is, and we will match it to a machine on our shelf rated to carry it.
• Wrong if you want rear suspension. Suspension stops at the 80 mm fork; send us your route and we will find a bike on our shelf with a rear shock.
• Wrong if you need 12 mph up 10% grades with a load. With 260 lb aboard, the model holds 10 mph on 10% and 9 on 12%; send us your steepest climb and your load, and we will price the ride before you buy.

Buy it if / Buy something else if

Buy it if you want a longtail you can step through, with a 32-inch rack, a 450 lb payload, a torque sensor and room for a second pack: about 74 miles at 12 mph on the throttle with 260 lb aboard on one pack, on level pavement.

What it needs from you: a height inside Addmotor's 5'4" to 6'2" window, a load of 450 lb or less, a state whose e-bike definition includes the Graoopro, and, if a child rides the rack, a seat that satisfies that state's wording.

For $1,499 you get a 750 W rear hub motor, 80 N·m in Addmotor's figures, and a 960 Wh pack, an 80 mm fork, mechanical discs, seven Shimano gears, a 32-inch rack and turn signals. Spread over Shop Pay's 12-month sample plan on our listing, it costs $135.30 a month at 15% APR, $1,623.60 in all.

Buy something else if you are shorter than 5'4", where the G30-CARGO 2.0 is $1,699; if your state's words leave the Graoopro outside its e-bike definition, where the same G30-CARGO 2.0 sits inside 19 of those 20 states; or if you want hydraulic brakes and fat tires, where the M-81 is $1,099.

Our Addmotor brand profile sets the Graoopro beside the Addmotor bikes and trikes on our shelf, and our e-bike reviews hub collects the rest of our reviews.

Before you buy: the checklist

Ten checks come before the $1,499; the first three settle who rides, who rides along and where you can ride.

1. Check your state in the class table and the passenger tables, then open its page in our law atlas.
2. Ask the agency behind each trail and park on your route what it allows.
3. Add up yourself, everyone and everything on the rack and what you wear, and keep the total at or under 450 lb, with 150 lb or less on the rack.
4. Take your inseam measurement and find your row in the saddle table.
5. Pick a child seat or rack bag made to mount on a rack 7 inches wide.
6. Decide on one pack or two, and read the range table for each.
7. Look up your ride in the range tables, add the climbing, and hold 15% of the pack back.
8. Choose an indoor charging spot that stays between 50 and 77 °F.
9. Find a parking spot and a lock point for a bike 27 inches wide and 78 long.
10. Rehearse starting and stopping with a load in an empty lot before a child rides along for the first time.

Buying it from us

Why buy the Graoopro from Redtail

Our listing priced the Graoopro at $1,499 on October 8, 2026, with $2,299 shown as the regular price, in four colorways. Addmotor's own page listed the same $1,499 and $2,299 that day.

Each colorway has its own row. On October 8, 2026 Neptune Blue was in stock on our store and at Addmotor; Orange, Starry Blue and Green read sold out on our store and as preorders on Addmotor's page, so for those three, email us first and we will ask Addmotor for a date.

The button puts Neptune Blue in your checkout at the price our store listed on October 8, 2026.

Frequently asked questions

How far can the Addmotor Graoopro go on one charge?

Addmotor prints 105+ miles on one pack and 210+ on two, on assist level 1 (the Technical tab). On the throttle over level pavement, the model gives a 180 lb rider about 83 miles at 12 mph on one pack and about 164 on two with the second pack's weight counted; every 1,000 feet of climbing at 10 mph takes another 129 to 159 Wh (the range tables).

Does the Graoopro come with a second battery?

Not in the box. Addmotor's buy box sells the bike with one 960 Wh pack and offers the second, the "20Ah Samsung UL-Certified Battery", as an add-on, and our listing ships one pack too; email us and we will quote the two-pack build (the battery section).

Should both packs be charged together?

Each pack takes about 10 hours from empty on Addmotor's 48 V, 2-amp charger, by the arithmetic of amp-hours over amps, so two packs on one charger take about 20 hours in all. Whether both can charge on the bike at once is for the manual that ships in the box; ask us and we will put the question to Addmotor (the battery section).

How much weight can the Graoopro carry?

450 lb in all, in Addmotor's Technical tab, counting you, everything on the rack and what you wear. Addmotor's October 16, 2023 post splits it as "300+150 lbs", and its October 5, 2023 post gives the rack "a max load capacity of 150 lbs"; its launch press release the same day gave 500 lb, "300 lbs + 200 lbs", so ask us before loading past 450 (carrying).

How much does the Graoopro weigh?

72 lb in Addmotor's Technical tab and its January 29, 2026 post; neither says whether the pack is included. A second pack adds 13.2 lb, by Addmotor's answer on the spare pack's page (weight and size).

What height do you need to ride the Graoopro?

Addmotor's size window runs from 5'4" to 6'2". For a 5'8" rider with the median 32.6-inch inseam, the 109% formula puts the saddle top 35.6 inches above the pedal, and Addmotor's seat post runs 33 to 42 inches off the ground (the fit section).

Can the Graoopro carry two kids?

Addmotor's October 16, 2023 post says an attachable seat makes it "suitable for transporting one or two kids", within the rack's 150 lb in its launch post and the 450 lb in all. Child seats are bought separately, and eleven of the 29 jurisdictions inside the e-bike definition write in how a young child may ride (the passenger section).

Does the Graoopro have a torque sensor?

Yes, in Addmotor's words: the Performance tab lists a "Torque Sensor", and the feature copy says "With 36 torque sensing points, the PAS initiates intervention when the pedal is shifted by 20°" (the motor).

What brakes does the Graoopro have?

Mechanical discs: Addmotor's Performance tab lists a "Mechanical Disc Brake", as the table in its January 29, 2026 post does; that post's prose says hydraulic, so if it decides your order, ask us and we will confirm the build (brakes and lights).

Can you ride the Graoopro on the throttle without pedaling?

Yes. Addmotor's Performance tab lists a "Variable Speed control - 1/2 Twist Throttle", and every speed in the range tables has a throttle-only figure.

Is the Addmotor Graoopro street legal, and what class is it?

That depends on your state's wording. On October 8, 2026, Addmotor's 750 W and 20 mph fall inside 29 jurisdictions' e-bike definitions, including California's "does not exceed 750 watts", and outside 20 (the class table).

What is a longtail cargo e-bike?

A cargo bike whose frame runs on behind the saddle to carry a long rack over the rear wheel. On the Graoopro, Addmotor's "Reinforced Longtail Aluminum Alloy" frame is 78 inches long on a 52-inch wheelbase with a 32-inch rack (the frame and the rack).

Is the Graoopro worth it?

For a rider 5'4" to 6'2" who wants a step-through longtail with a 450 lb payload and room for a second pack, it puts them together for $1,499, or $135.30 a month over 12 months at 15% APR on Shop Pay's sample plan. Riders under 5'4" are better matched to the G30-CARGO 2.0 (the verdict).

What warranty does the Graoopro have?

Buy it from us and any fault comes to us first; we open the claim with Addmotor and keep at it until the bike is fixed. Email us before checkout and we will get Addmotor's written terms for your order confirmed in writing.

Where are Addmotor bikes made?

Addmotor's About page says the company "has its own factory for designing and manufacturing products"; what it places in El Monte, California, where the story began in 2011, is the warehouse and showroom. For the factory behind the Graoopro, email us and we will ask Addmotor, and our Addmotor profile sets out the company's records in full.

Limitations of this review

This review leaves twenty-one points open; here they are, so you can weigh each one.

1. We sell this bike. Read its red flags as closely as its green ones.
2. This review is specification-verified: each figure is drawn from Addmotor's published documents, statutes, our own store record, a study the range or fit section cites, or arithmetic shown here.
3. Every range figure models a single steady ride at one speed on one grade, with no wind and no stops; real stops, starts, headwinds, soft ground and pulling away with a loaded rack all use more.
4. Bafang's figures stand in for Addmotor's motor in the model. Addmotor publishes the motor's rating, peak and torque; its speeds and efficiency come from the comparable Bafang unit.
5. Addmotor prints two peaks for the motor: 1,000 W in its copy and its 2023 and 2024 posts, 1,300 W in its stat graphic and its 2025 sale posts. Every table in the range model holds the 750 W rated curve and the 80 N·m cap, so whichever peak is right, the miles stay the same.
6. The model is least checked where the motor works lightly. When your legs supply most of the power, as in the steady-pedaling column, the miles depend on motor losses that no published motor map was available to confirm.
7. The two-pack figures add the second pack's watt-hours to the first. Addmotor does not set out for the Graoopro how its two packs share the load; if they run in parallel, each cell carries less current and loses a little less, so the two-pack figures sit on the careful side.
8. No measured range day on the Graoopro turned up. The formula section ends with the sources searched.
9. The figures count the whole pack as usable. How much of it the battery management releases is not given in the documents read here; researchers at KIT measured one pedelec using 75% during a standard range test.
10. The tire coefficient is a field average for commuter tires, from 273 riders; Addmotor names the Graoopro's tires by size and tread only, and the tire table brackets the figure.
11. Laboratory data from a single cell carry the cold figures. Addmotor's Samsung 21700 cells come without a model number, so the middle line follows McMaster University's LG HG2 cell and the brackets come from Samsung's and other published data.
12. Addmotor measures the saddle from the ground, where the formula measures from the pedal. With no bracket height or crank length to bridge the two, the saddle table gives the distance each rider needs, and a tape measure on the bike and the heel check finish the job.
13. Addmotor's size drawing gives no single scale: at each of three trial scales it matches at most one other printed dimension within 3.5%, so no grip position is taken from it and no lean or hand load is computed (the formula subsection shows each comparison).
14. 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, and the 109% formula is a starting point the heel check finishes.
15. The battery's certification is as Addmotor describes it: "UL Certification UL 2271" on the stat strip. No certificate number was read.
16. Addmotor's records disagree on the brakes. The Performance tab and the table of its January 29, 2026 post list mechanical discs; that post's prose says hydraulic.
17. The front tire's width has changed in Addmotor's records: 24 × 2.5 in its October 13, 2023 comparison, 24 × 2.0 on today's tab.
18. The rack's own rating is from Addmotor's October 5, 2023 post, 150 lb; today's tabs give the rack's size and not its rating, and Addmotor's press release of the same day split a 500 lb total as 300 + 200.
19. The Technical tab does not say whether its 72 lb includes the pack. The bike-weight table runs both readings.
20. Addmotor's FAQ says a manual comes with each bike, and no online copy of the Graoopro's was found. Questions the manual may answer, such as charging both packs at once, are ones we will put to Addmotor for you.
21. The class and passenger tables read each state's words as our atlas and the census record them on October 8, 2026, and colorways, prices and stock as our store and Addmotor's page showed them that day. Each can change, as can the Shop Pay terms and Addmotor's preorder dates.

The bottom line

At $1,499, the Graoopro puts a 750 W rear hub motor, a torque sensor and a 960 Wh pack on a step-through longtail with an 18-inch step, a 32-inch rack, an 80 mm fork, turn signals and a 450 lb payload, with room for a second pack.

The model puts a 180 lb rider on level pavement at about 83 miles at 12 mph on the throttle with one pack and about 164 with two, and at 74 with 260 lb aboard on one; climbing costs 129 to 159 Wh per 1,000 feet at 10 mph on the throttle.

The right owners are riders 5'4" to 6'2" who carry a child or the week's shopping behind them, keep the load at or under 450 lb, have a doorway wider than 27 inches, and live where their state's e-bike definition takes in the Graoopro, with its passenger rule read before a child rides along.

Shop Pay's twelve-month sample plan puts it at $135.30 a month at 15% APR.

Before checkout, ask us three things: whether your miles call for one pack or two, where your saddle belongs for your inseam, and what your state allows for a child on the rack. Email your miles, height and state, and one reply answers all three.
