Aventon Abound LR Review 2026: Two Kids, 440 lb, Range

Aventon's long-rack cargo bike as its listing reads on October 9, 2026, its range and fit worked out from those rows and set against two reviewers' timed runs, and two cargo bikes we sell whose makers say they carry two children: the Eunorau MAX-CARGO 2.0 and the Addmotor Graoopro.

By Milad Ghobadibeygvand, BScN (Western University, 2014), Redtail eBikes. Verified October 9, 2026. Part of our guide to all 16 Aventon models; for the shorter one-passenger version, read our Abound SR review.

The Aventon Abound LR on paper: what Aventon prints

The Abound LR is Aventon's long-rack cargo bike: a 750 W rear hub, a 733 Wh battery and a 143 lb rack on an 88 lb step-through frame with a 52-inch wheelbase and 20 × 3.0 inch tires. It is sold in one frame and one size, in Sage and Matte Stealth, under a feature heading that reads "Carry two children on the Abound LR."

Every row below is Aventon's own, read on the Abound LR page and in its product record on October 9, 2026.

Two of today's figures differ from the launch reviews, so both readings are here. In March 2025 Electric Bike Report listed the pack as "36V, 20Ah, 708Wh" and Electric Bike Review as "708Wh", with a "Motor Peak Output: 1183W"; Aventon's table on October 9, 2026 prints 733 Wh and 1,188 W, and this page's range model runs on Aventon's current rows.

Both reviews also give a height range reaching 6'6", where Aventon's page and size tool now stop at 6'3".

What comes with the bike reads differently by source, so all four are here. Aventon's table names fenders and the rear rack; its foot board listing says "Footboards are included with the purchase of the Abound LR"; its SR-or-LR guide adds "a lockable center storage pouch"; and Bikerumor's launch review listed "rear footboards, front and rear fenders, a rear rack, and a lockable storage bag".

Price, the December ship date and where to buy one

Aventon charges $1,999 for the Abound LR in either color, and on October 9, 2026 its page took pre-orders for the Matte Stealth under "Expected Ship Date: December 5, 2026". The same day's product record marked the Sage unavailable, its pre-order switched off; on October 8 both colors had been on pre-order to ship December 6.

Each color's own record on Aventon's page; the buy box shows the date for the color selected.

Financing in the buy box reads "Starting at $97 /mo or 0% APR with Affirm", and the add-ons beside it include a $499 spare battery and a $259 fast charger. The pack moves between bikes, in Aventon's words: "your Abound LR battery will also work on the Abound SR, Aventure 3, Level 3, and Pace 4".

There are two ways to buy one: online, or through the "BUY AT A NEARBY BIKE SHOP" button on Aventon's Abound LR page, at one of the "1,800+ Bike Shops" Aventon lists "for maintenance, service, and repairs". Aventon's terms, as that page prints them: "2 Year Warranty from the date of purchase", "Lifetime Frame Warranty *with ebike registration" and "14-Day Returns".

Two children on the back: what the Abound LR carries

Aventon rates the Abound LR for 440 lb in all, rider, children and cargo together, with no more than 143 lb on the rear rack, and sells it to "Carry two children". Its own SR-or-LR guide locates the difference in the deck: "The SR's rear rack is 22 inches. The LR's is 29 inches."

The rack's limit covers the children, their seats and any bags behind you, so total that first; what is left of the 440 lb is yours and the front of the bike's.

Subtraction from the two limits Aventon prints, "Total Weight Limit 440 lbs" and "Rear Rack Weight Limit 143 lbs". With the rack full, a rider over 297 lb reaches the total before the rack does.

The parts that carry children are sold separately, and several fit the LR and not the SR. Read in Aventon's catalog on October 9, 2026:

Each part's own listing and product record, read October 9, 2026 (the Child Carrier Kit, the LR handrail, the LR seat pad, the extension bracket, the Passenger's Chair, the Thule seat, the foot board).

Of the parts Aventon lists for the LR, one prints an age: the Abound Seat Pad, listed for the Abound and Abound LR, which "can fit up to two children with a total weight capacity up to 143 lbs, designed to fit children from the age of 5-10 years old". For a younger child, you can fit the Thule seat, and the Child Carrier Kit's listing says the kit takes it "if the seat pad is disconnected".

What a load costs on a hill has been measured on this bike. Electric Bike Review climbed with "my 180 lbs plus 40 lbs of cargo, totaling 220 lbs" and watched the speed drop "about 1 mph" up a 9% grade on the throttle; the range section sets that beside the model.

How far the Abound LR goes: range by speed, hill, load and cold

A full charge carries a 180 lb rider about 46 miles at a steady 15 mph on the throttle over level ground, about 31 miles at 20 mph, and about 76 miles at 15 mph with easy pedaling added. With children and cargo bringing the total to 440 lb, that 15 mph throttle ride shortens to about 34 miles, and a steady 8% climb at 10 mph covers 8 to 10 miles for one rider.

Work out your own trip in three moves:

1. Pick the row for your cruising speed in the speed tables, with or without pedaling.
2. Add the climbing: each 1,000 feet of gain at 10 mph on the throttle costs about 136 to 155 Wh on a 4% grade and 144 to 183 Wh on an 8% grade (hills).
3. Adjust for the load you carry and the temperature, then plan on spending three quarters of the charge.

The model behind every figure joins Aventon's rows to three published sources: a Bafang rear hub listed at 36 V and 750 W for 20-inch wheels, coast-down measurements of 273 commuters' tires and a cycling power equation validated on the road. The arithmetic is worked through at the end of the section.

Miles from one charge with 180 lb aboard on level pavement at 77 °F; the pale bars add 75 W of easy pedaling.

Does riding faster shorten the Abound LR's range?

Every step up in speed costs miles: about 67 at 10 mph, 46 at 15 mph and 31 at 20 mph on the throttle, so going from 15 to 20 mph gives up about a third of the trip. The air does it: in Martin's road model the power drag takes rises with the cube of speed, and the tires' share only in proportion.

Throttle alone with 180 lb on level ground at 77 °F, up to the 20 mph the LR ships with. The right-hand column keeps 25% of the charge in hand, the margin a Karlsruhe Institute of Technology bench found a pedelec holding back.

Pedal easily, 75 W of your own, and the 15 mph trip stretches from 46 miles to 76. Without the motor, 75 W moves this 88 lb bike and a 180 lb rider at about 10.0 mph, and 150 W at about 13.9 mph.

Full-pack miles for 180 lb aboard on flat pavement. The 183-mile cell carries the most doubt on the page: at 150 W of rider power the motor barely works, and none of the sources this model draws on publishes its efficiency at so light a load (Limitations, item 8).

Raise pedal assist to the app's 25 mph setting (the class section) and the miles above 20 mph go quickly:

From a full pack with 180 lb aboard on level pavement at 77 °F; pedal assist alone runs above 20 mph, since the throttle never does.

Does shifting gears save battery on the Abound LR?

Shifting changes your pedaling, and the motor's load stays where it was: it sits in the rear hub and spins with the wheel, so what saves battery is the share of the work your legs take on.

Each figure is battery watt-hours per mile with 180 lb aboard and the motor limited to its 750 W rating; on the hills tables it may reach its 1,188 W peak.

The cassette still earns its place. At 20 mph in the 52/12 top gear of Shimano's 12-32T eight-speed your cranks turn about 71 times a minute; in the 52/32 bottom gear, pedaling at 60 rpm moves the bike about 6.4 mph.

What does a hill cost the Abound LR's battery?

Climb a steady 8% grade at 10 mph on the throttle and a full pack lasts a 180 lb rider 8 to 10 miles; the top steady speed on that grade is 15.1 to 16.7 mph. Two numbers share each cell because Bafang published the stand-in motor in two speed versions: on level ground from 15 to 20 mph on the throttle they land within 3 miles of each other, and on a climb they part (formula).

180 lb aboard at 10 mph, the pack held to Aventon's 1,188 W peak and the motor to its 80 Nm.

Miles at 10 mph and the throttle's top steady speed, 180 lb aboard; each span covers both published versions of the stand-in motor.

Past 10%, the legs have to help: on a 12% grade the throttle alone holds at most 8.9 mph on the faster motor version and 12.1 on the slower, while easy pedaling spends a full pack over about 6 to 8 miles of climbing.

Two reviewers timed this bike on hills, and both beat the model's steady figures. Electric Bike Report's 180 lb tester took Hell Hole, "a 0.30-mile climb with grades over 12 percent", at an average of 13.9 mph on the throttle and 16.0 mph pedaling in the highest assist; its January 2025 method page gives the climb "an average grade of 12%".

180 lb aboard on a steady 12% grade; each model bar spans both versions of the stand-in motor.

The model's fastest steady speeds for 180 lb aboard; pedaling spans 75 to 150 W from the rider. The last column holds the controller's 33 A at the 42 V Aventon's charger puts into a full pack.

At Aventon's printed 1,188 W peak the model sits under both timed averages. That peak is the controller's 33 A at the pack's 36 V nominal; Aventon's charger row reads "36V Output: 42V", and at 42 V the same 33 A is about 1,386 W, where both averages fall inside the model's spans.

The review gives neither the pack's charge nor the current drawn, so that reading is our inference, and the climbing rows here read as a floor for a freshly charged pack.

How much range do two kids and a full rack take?

On flat ground each 50 lb you add costs about 2 to 3 miles of the 15 mph figure; on a climb the load counts for far more, and at the full 440 lb the throttle's steady speed up an 8% grade falls to 3.1 to 8.1 mph. Count everyone: Aventon's 440 lb is you, the children, their seats and the cargo.

Throttle only, full pack, 77 °F; the climb column spans both motor versions. At 280 lb and above, the faster version runs out of peak power for 10 mph up 8%, and at 380 lb the slower one does too.

Take a 180 lb parent with 100 lb of children and seats on the rack, 280 lb in all: up an 8% grade the throttle then holds 9.9 to 12.8 mph, against 15.1 to 16.7 mph with the parent riding alone.

Top steady throttle speed by total load, with the pack limited to 1,188 W and the speed capped at the shipped 20 mph.

Rider, passengers and cargo together, on the throttle; each cell spans the stand-in motor's two versions.

Electric Bike Review loaded its LR to 220 lb, "my 180 lbs plus 40 lbs of cargo", and rode two hills. On "a steep 9% grade, holding the throttle, it dropped about 1 mph", and on "a longer 5-7% grade, it held steady at the max 20 mph".

The model's fastest steady throttle speeds for 220 lb aboard, both motor versions, capped at the throttle's 20 mph. Neither hill's length is published.

On the 5–7% hill the full-pack column reaches the 20 mph cap at the shallow end of the grade. On the 9% hill the reviewer lost about 1 mph, far less than any steady figure here allows; a short hill taken with a run-up holds speed that a long steady climb cannot, and the review gives neither hill's length (Limitations, item 9).

Does cold weather shorten the Abound LR's range?

Cold costs range: the 15 mph throttle figure of about 46 miles becomes about 37 at 32 °F and about 33 at 14 °F. Chilled cells give back less of their stored energy, and colder air is denser to push through.

Pack energy comes from McMaster University's 0.5C discharge runs on an LG cell, and the figures in brackets cover the other published cell data. Aventon's battery row names "LG 21700 cells" and no model (Limitations, item 6).

Aventon's page tells owners to keep the battery in a climate-controlled space for storing and charging alike. On a winter morning, leave the pack indoors and click it in just before you set off; it releases "directly through the bike's display", with no key.

Do the tires change the Abound LR's range?

Swap in a slow-rolling tire and the 15 mph figure loses about 6 miles. Aventon names its tire, an Innova IA-2131 in 20 × 3.0, and none of the sources this model reads publishes a rolling-resistance measurement of it, so the rows use field measurements of everyday riders' tires.

Rolling resistance as Tengattini and Bigazzi, 2018 found it, coasting commuters down on their own bikes. Pump to the figure molded on the sidewall.

The drag area is the same study's figure for 37 upright riders on cruisers, the closest of its groups to the LR's 720 mm BMX-style bar; riding hunched like its mountain bikers would add about 2 miles at both 15 and 20 mph.

What Aventon's 60 miles means as a ride

Aventon's "Up to 60 miles" is a ride of about 16.8 mph with easy pedaling for its 165 lb rider, or about 11.9 mph on the throttle alone. Its footnote pins the figure to that rider "on a paved, flat road, in Eco Mode, with Ride Tune set to the default settings".

The steady level-ground speed at which the model spends exactly 733 Wh over 60 miles at 77 °F; on the slower motor version, about 10.2, 15.8 and 18.6 mph.

Aventon's range footnote lists "cadence" among what changes the figure, a pedaling word, so the easy-pedaling column is the nearest reading of how Aventon reached it.

Two reviewers rode the LR's battery flat. Electric Bike Report's charts put its Turbo run, by a 190 lb tester, at 36.1 miles and its Eco run, by testers of 185 and 155 lb, at 80.3 miles, at the default 20 mph limit; its testers "did not add any additional cargo weight". Electric Bike Review reached 75 miles in Eco "on flat ground" and, in its prose, 36 in Turbo, where its results box says 38.

Each cell is the steady level speed at which the model spends all 733 Wh over that distance at the tester's own weight, at 77 °F; a span covers both of a run's printed figures or testers.

Electric Bike Report's speed test averaged 20.2 mph in Turbo and 13.4 mph in Eco on level paths at the 20 mph setting. A Turbo rider at 20 mph sits between the model's throttle-only and easy-pedaling speeds for 36.1 miles, and an Eco rider at 13.4 mph sits under its easy-pedaling speed for 80.3, so the model and the runs agree in kind.

They cannot be matched mile for mile: neither review prints the range run's own speed, stops or climbing. On the 708 Wh both reviews print for their test bike, every speed in the table falls by about 0.1 to 0.8 mph.

The range arithmetic, step by step

Three things set the energy a mile costs: the tires rolling, the air pushing back and any climb; the motor's and the battery's losses then add their share, and the pack's watt-hours divided by that cost is the range. The power at the wheel follows the model Martin and colleagues validated on the road in 1998:

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

In it, v is your speed, m the combined mass of you, your load and the bike, g gravity, θ the angle of the grade, Crr the tires' rolling resistance, ρ the air's density and CdA the drag area of rider and bike together.

One ride worked through, 15 mph on the throttle with 180 lb on level ground:

1. Mass. 180 lb of rider and 88 lb of bike come to 121.6 kg.
2. Rolling. 6.71 m/s × 121.6 kg × 9.81 × 0.0074 = 59.2 W.
3. Air. ½ × 1.184 × 0.64 × 6.71³ = 114.2 W.
4. At the wheel. 59.2 W + 114.2 W = 173.4 W.
5. The motor. Aventon names the motor's maker, Shengyi, and no model or efficiency, so the stand-in is Bafang's RM G0F0.750.D/DC, a rear gear hub listed at 36 V and 750 W for a 20-inch wheel, taken at the 80% efficiency Bafang gives as its floor; at 15 mph it runs at 75.0% and draws 231.2 W from the battery.
6. The battery. The pack's internal loss at that current is 3.4%, so the cells deliver 239.2 W.
7. Per mile. 239.2 W ÷ 15 mph = 15.95 Wh each mile.
8. Range. 733 Wh ÷ 15.95 Wh = 46.0 miles from a full pack, or 34.5 to plan on with a quarter in reserve.

Bafang's workbook gives that hub two speed pairs, and only the faster one (490 rpm unloaded, 420 at its rating) spins the LR's 21.98-inch wheel past Aventon's 25 mph setting: 32.0 mph unloaded, against 21.6 for the slower pair (330 and 290 rpm). The faster pair runs every table.

The slower pair sets the other end of each climbing span; on level ground on the throttle it gives 43 miles at 15 mph and 31 at 20, within about 3 miles of the faster pair.

Will the Abound LR fit you? One size, 24 to 34 inch inseam

One size covers Aventon's whole 4'11" to 6'3" range on the Abound LR, and its size tool caps the inseam at 34 inches, a figure 65 of 100 surveyed adults at 5'11" exceed. By the 109% formula, applied to the Army's survey of 6,068 adults, a typical 5'8" rider needs the saddle top 29.1 inches above the crank axle.

Find your fit in three steps:

1. Stand barefoot against a wall and measure floor to crotch; Aventon's window is 24 to 34 inches.
2. Read your saddle height off the saddle table.
3. Check it on your first ride with the heel method.

Inseams of 6,068 adults in the Army's ANSUR II survey, counted against the window in Aventon's size tool on October 9, 2026.

What saddle height does the Abound LR need?

By the standard formula, a typical 5'4" rider's saddle top sits about 26.8 inches above the crank axle and a typical 6'0" rider's about 31.6 inches. The rule is 109% of inseam measured from the pedal axle with the crank in line with the seat tube; take away this bike's 165 mm (6.5 in) crank and you have the crank-axle figure in the table.

Typical inseam is the middle 90% at each height in the US Army's ANSUR II survey; the saddle columns are for the median body at that height, the last two the formula's published range. Your own measured inseam overrides any row.

Aventon prints the post's length, 350 mm, and the seat tube's, 380 mm, but no minimum insertion and no saddle range, so this page does not compute where the saddle tops out.

Three reviewers found the ceiling on the road. Electric Bike Review's 5'11" rider, "with a 33-inch inseam", found the pedal extension short; Electric Bike Report's 5'11" rider had "much more of a bend than I hoped for" at full height; Bikerumor's 6'1" reviewer wanted "a touch more post".

That 33-inch inseam sits inside Aventon's window, and the formula puts its saddle 29.5 inches above the crank axle (28.5 to 29.9 across the published range). If your inseam is 33 inches or more, have a dealer set the saddle to your figure before you buy; Aventon's own guide tells riders near "6'2" or 6'3" specifically" to "sit on a floor model at a dealer before you buy".

Two of the reviewers report room in the frame for a longer post: "about 4 more inches in the seat tube", by Electric Bike Review's count, and "an additional 50mm", by Electric Bike Report's.

How Aventon's 34-inch cap lands at each height, in the same survey:

ANSUR II adults at each height (56 at 6'3"), counted against the window in Aventon's size tool.

Can I put both feet down on the Abound LR?

Aventon publishes no standover height for this step-through frame, so the page cannot count how many riders clear it. Bikerumor describes "a very low standover".

A flat-footed stop is decided by the saddle at its lowest, and Aventon does not print that either. If you are close to the 4'11" floor, ask a dealer to drop the saddle all the way and check that both your feet reach the ground before you order.

How upright will I sit on the Abound LR?

Upright, with a bar you can raise, though the lean is not computed here: Aventon's tables give no grip position and carry no stem row. They do print a 521 mm stack, a 420 mm reach, a 70° seat angle and the 720 mm "BMX Style" bar, and the description names an "adjustable quill stem".

Electric Bike Report found that "its geometry places the rider in an upright position", and Electric Bike Review counts "140mm of vertical adjustability" in the quill stem.

How much weight will rest on my hands?

The hand load is not computed, because it turns on a grip position Aventon does not publish. The tables give the 70° seat angle and the 720 mm bar; how much weight the upright bar moves from your hands to the saddle depends on that grip point.

For scale, Carahalios (2015) measured 15% of body weight through the stem with riders on an ergometer holding the brake hoods at 2 W/kg. The LR's grips are "Aventon Ergonomic Comfort lock on grips"; if your hands tingle on a long ride, raise the bar first.

How do I set the saddle when the bike arrives?

Move the saddle until a straight leg just rests its heel on the pedal at the bottom of the stroke; pedal on the ball of your foot and the knee then keeps the slight bend the formula targets. Then check the height against the saddle table.

1. Lean the bike on a wall, sit on it, and turn one pedal to its lowest point with your heel on it.
2. Move the 30.9 mm seatpost until that leg is straight, then close the clamp.
3. Ride on the ball of your foot: at the bottom of each stroke your knee keeps a slight bend.
4. If your hips rock from side to side, drop the saddle 5 mm at a time.

The 350 mm post is sprung, with 50 mm of travel, so set the height while sitting on it.

The fit formula, worked

Crank axle to saddle top = 1.09 × inseam − crank. Worked for the survey's median 5'8" rider, whose inseam is 32.6 inches: 1.09 × 32.6 = 35.6 inches pedal axle to saddle top; less the 6.5-inch crank, 29.1 inches above the crank axle.

The other common rule, LeMond's 88.3% measured from the crank axle, puts the same rider's saddle at 28.8 inches; among Peveler and colleagues' riders it landed the knee in the recommended 25 to 35° bend only about half the time. Across the 106% to 110.4% that Ferrer-Roca et al., 2012 recommend, the figure spans 28.1 to 29.5 inches.

The Mercer fit test

We hold every bike we review against the same seven people, the Mercers, our editorial cast. A verdict below rests on one of three things: a figure Aventon prints, the share of surveyed adults at the member's height whose inseam fits Aventon's window (the fit chart), or the state-law table in our 50-state guide.

What the rows read from: the 4'11" to 6'3" rider window and 24 to 34 inch inseam window in Aventon's size tool, the 440 lb and 143 lb limits, the two children Aventon names, and Class 2 at 20 mph with an app setting to 25.

Ruth, Maya and Dana, at 5'5" to 5'7", fit the one size at 95 to more than 99 in 100, and Dana's two children ride inside the rack's 143 lb; at 6'1", 94 of 100 riders Jack's height outgrow the 34-inch cap, so his bike to read is the Graoopro, which Addmotor sizes to 6'2". Ivy rides behind on the chair, and Cole's answer starts with his state's age rule.

Security, the app and the 4G plan

Beyond the rack, the LR's case is security: an Aventon Control Unit with 4G and GPS that tracks the bike, sounds alarms and can shut the motor down from the app, free for the first year and paid after that. Aventon's footnote grants a "complimentary 4G connection subscription" for the first year from registration, after which "a paid 4G connection subscription will be required to maintain access to these services".

The features, as the LR's page names them:

• Tracking and alarms. "GPS Location", "Geofencing", "Report lost", "Remote shutdown" and an "Alarm and Motion sensor", plus a "Status report" and a "Transportation Mode" for long trips.
• The kickstand lock. Locked, the kickstand stops the bike "from being moved or rolled away while the kickstand is down".
• The battery. Aventon's "Cross-Model Keyless Battery System" releases the pack "directly through the bike's display", with no key to carry.
• A startup password, a code you set on the display, plus over-the-air updates.
• Riding aids. Cruise Control; Sensor Switch between torque and cadence response; Ride Tune, which Aventon says makes it "easier to start smoothly with heavy loads, maintain control with passengers on the back"; and Hold Mode, "up to 30 seconds at a time".
• Boost. For "up to 30 seconds at a time" the motor may give "up to 120% of specced torque and peak power"; the page's strip prints "1440W Peak in Boost".

Electric Bike Report gave the plan's price in March 2025 as "$20 annually or $2 per month" after the free year; Aventon's page prints no price for it.

How the motor feels is a rider's report, and Electric Bike Report's review gives one with children in mind: "The acceleration built steadily after a gradual start, which felt safe and controlled. We consider this appropriate for a cargo e-bike likely to be carrying child passengers."

Buying one second-hand? Before you pay, ask the seller to remove it from their Aventon app account and to tell you whether the 4G plan is paid up, since tracking and remote shutdown depend on it.

Safety certificates and recalls

The LR's page links two UL Solutions certificates: UL-US-2440621-3 for the bike's electrical system, which names the "abound LR" and the "abound SR", and UL-US-2440268-0 for a battery pack. The CPSC's recall database holds no record that names an Abound.

UL issued the e-bike certificate to Ride Aventon Inc. under "QGNS - Electrical Systems for E-Bikes", with both Abounds named as models. The battery certificate treats the pack as a recognized component, UL's form for a part built into a finished product; each certificate refers readers to UL's Product iQ "for additional information".

The CPSC's recall database, searched on October 9, 2026, holds one recall with Aventon in its title, the January 2024 Sinch.2 folding e-bike recall, whose remedy was "a free repair, including a software update to the controller". No record names an Abound, whether the search runs by title or by product name.

Class 2 as shipped, 25 mph or Class 1 in the app: where you can ride

The Abound LR ships as a Class 2 e-bike that stops helping at 20 mph on the throttle and pedal assist alike; in Aventon's app you can raise pedal assist to 25 mph, or switch the throttle off and ride it as a Class 1. Aventon's page prints the shipped setting in its class row, "Class 2 Ebike", and the faster one in its strip, "Top Speed 20MPH (Adjustable to 25MPH)".

Aventon's support article reads: "Out of the box, the bike ships as a class 2 Ebike (20mph max for throttle and PAS) and specific models (as advertised) can be unlocked into a class 3 configuration (20mph max for throttle & 28mph max for PAS)."

For the LR the advertised figure is 25 mph, as Electric Bike Report confirms: "Through the Aventon app, users can increase the bike's pedal-assisted speed to a maximum of 25 mph (making it a Class 3)".

The other direction is in Aventon's guide: "you can disable the throttle through the Aventon app to ride Class 1 if your local trails or bike paths require it".

Which setting you may ride, and where, is your state's call and the path's, whatever the app permits. Our 50-state e-bike law guide quotes each statute, and its state table lists who must wear a helmet, passengers included, and the age rules for a Class 3, including who may ride on one as a passenger. Until you have read yours, ride the LR at its shipped 20 mph with children aboard.

Abound LR or Abound SR?

Pick the LR for two children and the SR for one passenger: the frames share a motor, a battery and the 440 lb limit, and the LR adds $100, 8 lb and about 7 inches of wheelbase. Every cell below is a figure Aventon prints, taken from the LR page and the SR page as each stood on October 9, 2026.

Aventon's spec and geometry tables for each; the rack lengths and the footboards from Aventon's SR-or-LR guide of September 11, 2026, and the pegs from their listing.

Aventon's guide gives the wheelbases as 45 and 53 inches, "eight inches longer"; its geometry tables print 1,151.5 and 1,332 mm, 7.1 inches apart, and this page uses the tables.

The extra deck is what makes room for your second child, and the LR's parts show it: the handrail, the Child Carrier Kit and the extension bracket are each listed for the LR and not the SR. In the words of Aventon's SR-or-LR guide, "the handrail accessory, the one that gives a second child something solid to hold onto, only fits the LR's longer rack."

How is the Abound LR different from the first Abound?

The LR replaced the original Abound of 2023 and keeps its idea, a long rack on 20-inch wheels, with a new frame and new electronics. Bikerumor reported in March 2025 that "the Abound is splitting in two, with the Abound SR and LR", the letters standing for "Short Rack and Long Rack".

Aventon's guide lists what changed: the control unit's 4G and GPS security suite, "an 8-speed Shimano drivetrain from the original's 7-speed", "a gravity-cast aluminum front triangle", and tires grown "from 2.4" to 3.0"". Electric Bike Report, which calls the first version the "Abound AG", had "critiqued the original model for having a significant amount of flex when loaded up" and found the new frame's stiffness "definitely noticeable".

Some first-generation parts carry over: Aventon lists the LR's rear seat pad as "Designed for Abound LR and the first generation Abound", and the Child Carrier Kit for "Abound and Abound LR".

Two cargo bikes we sell like it

Two cargo bikes we sell are built for the LR's job, a 750 W rear hub under a long rack, and each maker says its bike carries two children: the Eunorau MAX-CARGO 2.0 at $1,699 and the Addmotor Graoopro at $1,499. Read on October 9, 2026, each was for sale at its maker and on our store at an identical price, with free shipping from us.

On its MAX-CARGO page, Eunorau writes that the MAX-CARGO 2.0 "can hold 2 children"; in a 2023 post, Addmotor describes the Graoopro's cargo area as "suitable for transporting one or two kids" with an added seat. Under each card, a table sets it against the LR.

The MAX-CARGO 2.0 in Green, as Eunorau photographs it; White is the other color.

Read on each maker's page on October 9, 2026; the range rows come from this page's model and our MAX-CARGO 2.0 review. Eunorau prints two weights, 85 lb in its spec table and 78 lb in its geometry chart; the table above uses 85.

Each maker's page as read on October 9, 2026; the range rows are from this page's model and our Graoopro review.

Which to choose: the MAX-CARGO 2.0 if you carry two children, since Eunorau says it holds two, it stops on hydraulic discs as the LR does, and it costs $300 less.

The Graoopro if you haul the heaviest loads or ride the longest days: 450 lb on a 72 lb frame, a rack 3 inches longer than the LR's by the two makers' figures, and a 48V 20Ah pack, for $500 less. The LR itself if you are under 5'2", or want Aventon's 4G security, the handrail parts and a dealer to service it.

Buying a MAX-CARGO or a Graoopro from us

Both ship free to the lower 48, and one team at support@redtailebikes.com answers your sizing and passenger questions before you pay and handles any repair claim after. Our shipping policy has orders "prepared and dispatched within 1–3 business days of confirmation", and most e-bikes arrive within 5 to 10 business days of dispatch.

Settle the size and the passenger parts before it ships: our refund policy takes a change-of-mind return only for a bike still unopened in its factory-sealed packaging and requested within 72 hours of delivery, with a 15% restocking fee and return shipping.

Green flags, and who the Abound LR fits

Green flags, each from the record:

• Sold for two children, with a handrail, a child kit and a second-seat bracket made for its 29-inch rack (cargo).
• A 750 W motor with 80 Nm and a 1,188 W peak, and a 30-second Boost to 1,440 W (specs).
• Hydraulic brakes with a 203 mm rear rotor; Electric Bike Report measured an average stop of 20 feet 7 inches.
• Independent battery runs of 80.3 and 75 miles in the lowest assist (Aventon's 60 miles).
• Timed climbs faster than the model's steady figures (hills).
• 4G tracking, a kickstand lock and a keyless battery (security).
• A UL 2849 certificate naming the Abound LR, and no federal recall naming an Abound (safety).

Who it fits, and who should read on:

Before you buy: the checklist

1. Measure your inseam barefoot against Aventon's 24 to 34 inches; at 33 inches or more, have the saddle set to your figure before you pay.
2. Total the rack: children, seats and bags stay under 143 lb, and everyone and everything under 440 lb (the rack table).
3. Choose the passenger setup, the Child Carrier Kit, a handrail with a pad, or a Thule seat with the extension bracket, and add its price (the parts).
4. Read your state's passenger, age and helmet rules in our 50-state guide.
5. Check the ship date for your color: the Matte Stealth's was December 5 on October 9, 2026, and the Sage's pre-order was off that day.
6. Measure where it will live: Aventon prints a 1,332 mm (52 in) wheelbase and 88 lb.

Frequently asked questions

How much does the Aventon Abound LR cost?

$1,999 at Aventon on October 9, 2026, for either color with no struck price; the Matte Stealth was on pre-order to ship December 5, and the Sage could not be ordered. The Abound SR is $1,899. Of the two bikes we sell like it, the Addmotor Graoopro costs $1,499 and the Eunorau MAX-CARGO 2.0 $1,699.

Is the Aventon Abound LR worth it?

If your family carries two children and wants 4G tracking, a kickstand lock and a dealer nearby, yes: Electric Bike Report calls it "a smart value purchase" and ran it 80.3 miles on one charge in Eco. For the same job at $300 to $500 less, see the two cargo bikes we sell like it.

How much does the Aventon Abound LR weigh?

88 lb by Aventon's table, and both Electric Bike Report and Electric Bike Review weighed it at 88.3 lb. The battery is 8.7 lb, so lifting it out leaves about 79 lb of bike to carry up steps.

What is the Aventon Abound LR's weight limit?

440 lb in total, which Aventon's table counts as rider, passengers and cargo together, and of that, no more than 143 lb on the rear rack. A 180 lb rider has 260 lb left, and with the rack loaded to 143 lb, any rider over 297 lb reaches the 440 lb total first (the rack table).

How many kids can the Aventon Abound LR carry?

Two, in Aventon's own words on the LR's page: "Carry two children on the Abound LR." Every child, seat and bag you put on the rack shares its 143 lb limit, and none of the Aventon parts we read is listed for a third child. On our shelf, Eunorau says the MAX-CARGO 2.0 "can hold 2 children".

Will a child seat fit the Aventon Abound LR?

Yes: the LR's buy box offers the Thule Yepp Nexxt 2 Maxi rack-mount seat at $269.95, and Aventon's extension bracket adds 120 mm of rack for a second child seat, rated 59 lb. The Child Carrier Kit works with that Thule seat once its pad is disconnected, its listing says.

Can an adult ride on the back of the Abound LR?

Aventon pitches its Passenger's Chair for the SR and LR for "family outings or bringing a friend along for the ride", within a 143 lb limit, the rack's own; the rider and passenger both count toward the 440 lb total. Read your state's passenger rule in our 50-state guide before you carry anyone.

What is the difference between the Aventon Abound LR and SR?

The same motor, battery and 440 lb limit; the LR costs $100 more, weighs 88 lb against 80, and rides on a 1,332 mm (52 in) wheelbase against 1,151.5 mm (45 in). Aventon sells the LR to "Carry two children", with a 29-inch rack against 22 in its guide, and the SR to "Carry A Single Passenger" (the comparison).

How is the Abound LR different from the original Abound?

It replaced it: Bikerumor reported in March 2025 that the 2023 Abound was "splitting in two" into the SR and LR. Aventon's guide lists the changes: the 4G and GPS control unit, eight speeds in place of seven, a gravity-cast front triangle, and tires grown from 2.4 to 3.0 inches (more).

How long is the Aventon Abound LR?

Aventon prints no overall length. Its geometry table gives a 1,332 mm (52 in) wheelbase and a 660 mm (26 in) chainstay, and its SR-or-LR guide speaks of "the LR's 53-inch frame" and a 29-inch rack.

How far can the Aventon Abound LR go on one charge?

Aventon rates it "Up to 60 miles", with a 165 lb rider in Eco on paved, flat road. For 180 lb on level ground with the full 733 Wh, the model gives about 46 miles at 15 mph on the throttle, 31 at 20 mph and 76 at 15 mph with easy pedaling; at the 440 lb limit, about 34 at 15 mph (range).

How fast does the Aventon Abound LR go?

20 mph as shipped, on the throttle and on pedal assist: the class row on Aventon's page reads "Class 2 Ebike", and its strip "Top Speed 20MPH (Adjustable to 25MPH)". Electric Bike Report's speed test averaged 20.2 mph in Turbo at that setting; read your state's rule in our state law guide before using the 25 mph one.

Can the Aventon Abound LR be unlocked to go faster?

Only pedal assist, and only to 25 mph, through Aventon's app; the throttle stays at 20, and Aventon's support article calls the faster setting "a class 3 configuration". The same app can switch the throttle off to ride as a Class 1, Aventon's guide says. In this page's model, a full pack lasts about 25 miles at 25 mph with easy pedaling for 180 lb.

What size rider fits the Aventon Abound LR?

From 4'11" to 6'3", with an inseam of 24 to 34 inches, by Aventon's size tool. Among surveyed adults at 6'0", 17 in 100 have an inseam that short, and three reviewers from 5'11" to 6'1" found the stock post short; a 5'8" rider with a 32.6-inch inseam needs the saddle about 29.1 inches above the crank axle (fit).

How big is the Abound LR battery, and how long does it take to charge?

36 V, 20 Ah and 733 Wh of LG 21700 cells by Aventon's table, charged from empty in "5 hours" on its 42 V, 4 A charger; Electric Bike Review puts it at "about 5-6 hours". The $499 spare also fits the Abound SR, Aventure 3, Level 3 and Pace 4, Aventon says.

How do you remove the Abound LR battery?

Through the bike's display, with no key: Aventon's "Cross-Model Keyless Battery System" releases the pack "directly through the bike's display", and Electric Bike Report adds that it "can be ejected through the bike's display or the Aventon app". The pack weighs 8.7 lb.

Is the Aventon Abound LR waterproof?

Aventon's answer: the LR is built to "the IPX5 water-resistant standard", protected "against low-pressure water jets from any direction" for "light to moderate rain or through small puddles", but "IPX5 does not mean waterproof", and it should not be pressure-washed.

How do you lock the Aventon Abound LR?

Aventon builds in three locks of its own, by its page: the kickstand lock, "preventing it from being moved or rolled away while the kickstand is down", the keyless battery and a startup password; with the 4G plan, geofencing and remote shutdown too. Bring a physical lock for longer stops.

When did the Aventon Abound LR come out?

March 2025. Bikerumor's launch review, dated March 11, 2025, says the LR "has been embargoed until now", and Electric Bike Report's review is dated March 10, 2025.

What else compares with the Aventon Abound LR?

In Aventon's line, the Abound SR at $1,899 for one passenger. On our shelf, the Eunorau MAX-CARGO 2.0 at $1,699, which Eunorau says holds two children, and the Addmotor Graoopro at $1,499, 450 lb on 72 lb; for Lectric's cargo bike, our XPedition 2.0 review sets it beside both of ours.

The bottom line

If you carry two children and want 4G tracking and a dealer nearby, the Abound LR does the job at $1,999, with a December ship date for the Matte Stealth. It carries 440 lb in all with 143 lb on the rack, computes to about 46 miles at 15 mph on the throttle for 180 lb, and fits riders whose inseam is 24 to 34 inches, though three reviewers from 5'11" up found the post short.

If you are under 5'2", or want Aventon's 4G security and a local shop, buy the LR once your inseam checks out against its window. For two children on a bike that dispatches within 1 to 3 business days, order the MAX-CARGO 2.0 at $1,699; for heavy cargo on a lighter frame, the Graoopro at $1,499. Both ship free.

Corrections: write to support@redtailebikes.com. The two pick photographs are their makers' own, cropped and scaled and nothing else, and the charts plot this page's computed figures.

Limitations

1. Steady rides only. Each range figure holds one speed on one grade from start to finish; wind, traffic lights and restarts all cost more on a real trip.
2. A stand-in motor. With only the maker's name, Shengyi, to go on and no model, efficiency or speed curve, the tables use Bafang's rear hub listed at 36 V and 750 W for 20-inch wheels, at its 80% efficiency floor.
3. Two versions of that motor. The workbook gives the stand-in two speed pairs that part on hills, which is why the climbing figures come as spans.
4. The full-pack column. The 1,386 W figure is the controller's 33 A at the charger's 42 V, an inference about a freshly charged pack; every central figure uses Aventon's printed 1,188 W.
5. The battery figure. Today's table says 733 Wh and the March 2025 reviews 708 Wh; the model takes Aventon's current figure, and on 708 Wh each range would come out about 3% shorter.
6. Cell temperature. In the cold rows the pack sits at air temperature and follows an LG 18650 cell's discharge data, Aventon naming no model for its LG 21700 cells; a pack carried out from a warm house starts above air temperature.
7. The tires. Aventon names the Innova IA-2131, and no rolling-resistance measurement of it was found in the sources this model draws on, so rolling resistance comes from coast-down tests of commuters' own tires, spread included.
8. Light motor loads. Pedal hard enough and the motor works at loads none of these sources rates for efficiency, which makes the 150 W column at 15 mph the least certain.
9. The reviewers' measurements. Neither review prints its range runs' speed, so the speed-test averages sit beside the model and never in it; Hell Hole's grade is the method page's average, and Electric Bike Review gives neither hill's length and prints its Turbo distance as 36 in prose and 38 in its results box.
10. Boost and the sensor modes. No row uses the 30-second Boost, and your pedaling counts as watts in either sensor mode.
11. The reserve. The 25% kept in hand is a Karlsruhe bench figure from another pedelec, since Aventon gives no reserve for the LR.
12. The survey's bodies. ANSUR II measured 6,068 Army personnel aged 17 to 58 between 2010 and 2012, a population that is not the public at large, and only 56 of them stand 6'3". Your own inseam decides your row.
13. The knee range. The formula aims for a 25 to 35° knee bend at the bottom of the stroke, as the literature advises, and an old injury or plain comfort can override it; the heel test and your own knees have the last word.
14. What Aventon does not print. No standover height, minimum insertion, saddle range, stem or grip position is published for the LR, so the page computes no standover share, saddle ceiling, lean or hand load.
15. The certificates' scope. Each certificate sends readers to UL's Product iQ for the full listing, which sits behind an account this page did not use.
16. Child seats and passengers. The catalog reading in the cargo section covers what Aventon lists and tags; the Thule seat's own age and weight limits are Thule's, and whether another maker's seat fits the LR's rack is a question for Aventon or a dealer.
17. Two wheelbase figures. Aventon's guide says 53 inches and its geometry table 1,332 mm (52 in); the page uses the table.
18. Prices and stock change. Every price, ship date and stock state here, Aventon's, the two makers' and ours, was read on October 9, 2026, and any of them can move.

This page expires when Aventon reprices, ships or relists the Abound LR or changes its tables, when Eunorau or Addmotor changes a pick's price or stock, or on January 9, 2027, whichever comes first; each triggers a re-check before republishing.
