The Aventon Abound SR is a compact electric cargo bike built for families, commuters, and anyone who wants to haul kids, groceries, or gear without a car. Powered by a 750W rear hub motor with a 60-mile range, it carries up to 440 lbs total payload — enough for a rider plus a passenger or a full week of errands — while staying small enough to park almost anywhere a regular bike fits.

Show full description and specs

The "SR" stands for Short Range geometry: a more compact frame than the standard Abound, fitting riders from 4'11" to 6'3" on a single size. New-for-2026 connected features include 4G/GPS tracking, geofencing alerts, and a startup password through Aventon's Control Unit (ACU) — meaningful theft deterrence on a bike this capable.

Who The Abound SR IS For

Parents replacing a second car for school drop-off and around-town family trips (rear seat pad and pegs sold separately let kids ride along).
Apartment and condo dwellers who need cargo capacity without a 6-foot longtail frame.
Riders 4'11" to 6'3" — the adjustable quill stem and one-size-fits-most frame cover a wide range.
Commuters carrying real loads — laptop bag, groceries, a passenger — who want a Class 2 e-bike (20 mph with throttle) that doesn't ride like a tank.
