Aventon Abound SR vs Abound LR

The Aventon Abound SR and the Abound LR are not a short and a long version of one geometry. The SR is the short cargo bike. Aventon’s table prints Class 2, 80 pounds, a 440-pound total, up to 60 miles, and a single-passenger carry line. Rider Guide’s price check on 24 September 2026, plus Sports Basement and Bentgate, print $1,899. The LR is the long rack. Aventon’s block prints Class 2, 88 pounds, the same 440-pound total, and up to 60 miles. The manual prints 89 pounds. Shops and Electric Bike Report print $1,999. Aventon’s own spec blocks, on the reads this desk already published, did not return a dollar for either. Nineteen hundred ninety-nine minus 1,899 is 100, and that hundred is the shop gap, not a price Aventon printed. The SR guide and the LR guide are the long versions.

The motor row matches. The bike does not.

Read Aventon’s motor cells and they look like a copy. Shengyi, 750 watts, 1,188 watts peak, 80 Nm, a torque sensor, a left-hand throttle. That is not permission to buy the cheaper one and expect the longer rack. Eighty pounds and 88 pounds are the product weight cells. Eighty-eight minus 80 is 8. The manual’s 89 makes it 9. EBR’s scale, 88.4, is a third LR number. Do not average 88 and 89 into 88.5 and then subtract 80. The hub page still applies to both: the motor is in the wheel, and a full rack does not get a climb gear.

The peaks leave Aventon’s row as soon as another desk types them. Rider Guide puts 950 watts on the SR and leaves 80 Nm alone. Electric Bike Report puts 1,183 on the LR. A dealer puts 1,440 on the LR and calls it Boost. Aventon’s own Boost sentence, on the LR page, is 120 percent of the specced torque and peak for 30 seconds, and it does not print a second watt. One hundred twenty percent of 1,188 is 1,425.6, not 1,440. The SR sheets this desk used for the short-bike guide did not print that Boost sentence. Do not hang 1,440 on the $1,899 bike because the long one has a dealer who did.

Eighty and eighty-eight are two bikes. The 440-pound cap is the same sentence on both.

Seven hundred thirty-three is the label. Seven hundred twenty is the product.

Both Aventon blocks print 36 volts, 20 amp-hours, and 733 watt-hours. Thirty-six times 20 is 720 on each. Rider Guide and Sports Basement print 708 for the SR at the same 36 and 20. Electric Bike Report prints 708 for the LR next to 19.6 amp-hours. The LR manual prints 19.88 amp-hours and no watt-hour. Thirty-six times 19.88 is 715.68. Thirty-six times 19.6 is 705.6. OutdoorGearLab’s comparison cell prints 720 and the prose says the label reads 733. A dealer line that says 48 volts and 15 amp-hours is not this pair. None of those watt-hours is a second battery. The watt-hour page is the unit. Do not average 708 and 733.

Both claims say up to 60 miles. That is not one ride. The SR block this desk read does not name a rider. The LR manual does: 75 kg, 86°F, 70 percent humidity, level road, lowest assist, and then three expected rows, 35, 44, and 60. Electric Bike Report’s LR loops were 75 miles in minimum assist and 38 in maximum, called flat. OutdoorGearLab’s was 33.4 miles with more than 1,700 feet of climbing. Those three tests are the long bike. They are not an SR result. Seven hundred thirty-three divided by 38 is about 19.3 watt-hours a mile, if you use the label and the hard loop. Seven hundred thirty-three divided by 75 is about 9.8, on the easy loop. Same label, different assist. Do not hand either rate to the short bike.

Class 2 on both blocks. Twenty-five is not 28.

Aventon prints Class 2 for both, and the speed rows this desk used say 20 mph with a throttle. The SR sheets did not show a 28 mph line or a 25 mph line. The LR block and the manual agree at 20. Other pages, including a 3 May 2026 FloridaBicycling post and a dealer, print a 25 mph unlock and call it Class 3. Digital Trends, 30 June 2025, said pedal assist in that setting goes to 25 and the thumb stays at 20. A U.S. Class 3 cutoff is 28, not 25. The class chart is why a 25 mph blog does not rewrite the sticker. Fork travel is the quiet difference that is actually on the maker’s pages: 50 mm on the SR, 51 mm on the LR. One millimeter is not the rack.

Who should buy which

Buy the SR if you want the short bike, one passenger, and the $1,899 the September shops print, and you can lift 80 pounds. The rotor split on that sheet is 180 mm front and 203 mm rear. Skip it if the job is a long deck. A 26-inch summary line on one aggregator fights the 20-by-3 component table. Use the tire in the shop.

Buy the LR if you want the rack the manual rates at 33 pounds in front and 143 in the rear, and you have seen 88, 89, and 88.4 and picked the scale you believe. The shop price in print is $1,999, a hundred dollars over the SR’s shop price, not a number Aventon put on both pages. The 440-pound total is the same cap, rider included. Thirty-three plus 143 is 176, before the rider and before the bike. The cap is still 440. The LR warranty line this desk has is 2 years, plus a lifetime frame if you register it. That sentence was not on the SR sheets used here, so it does not transfer. The XPedition 2 is the other longtail, with a class menu. This pair does not have one.
