Buying guide · Updated Oct 11, 2026
Range claims of 70–90 miles assume the lowest assist level, a light rider and flat ground. Battery size in watt-hours is the honest number, so that's what we rank on.
This ranking puts battery first, then value, build and power.

Ranked lower on this guide's criteria, or claims speeds or power above U.S. Class 1–3 limits.
Compare Wh (volts × amp-hours). 700–1,000 Wh is the long-range class.
Heavier riders and hilly routes can halve the claimed range.
Bigger batteries take 5–7 hours to charge; a second charger at work helps.
Lets you charge indoors and swap in a spare for very long rides.
About 20–30 Wh per mile for most riders, so a 720 Wh battery gives roughly 25–35 real miles.
It adds weight and cost. Buy the size your longest regular ride needs, plus a 20–30% margin.
