Overview
Yibykou's E8 is a 29 inch adult commuter e-bike with a 1000W peak motor, a 21-speed drivetrain and a removable 840Wh (48V 17.5Ah) battery rated for up to 70-80 miles in pedal-assist mode.
Reviewers who tested the top speed independently confirm it hits around 34 mph, matching the listing's claim, and describe the ride as sturdy and smooth on both streets and light trails. Five riding modes, including throttle-only, pedal assist and cruise, are shown on a waterproof LCD display, and the battery is UL listed.

- Removable 48V 17.5Ah (840Wh) battery

- 5 riding modes on a waterproof LCD display
Who it's for
Commuters and casual riders who want a fast, long-range e-bike with big 29 inch wheels for mixed pavement and light trail use, and who plan to swap or charge the battery separately rather than plug in the whole bike.
What buyers say
