Overview
Riding on small fat tires with suspension at both ends, this aluminum e-bike combines a hub drive, a twist grip shifter and an LCD display. Both pedal assist and throttle assist are listed, and a tool kit is included.
A high rider weight rating, both assist modes and dual suspension make for a capable all-terrain bike. The mismatch between the listed battery figures is the main thing to clarify before buying.
Who it's for
Riders who need a high weight rating and a bike that handles unpaved trails, streets and mountain ground. Those planning around range should confirm the battery capacity. Assembly is required.
Pros and cons
- High weight rating
- Throttle and pedal assist
- Tool kit included
- Battery figures conflict
- Brake type is disc only, no detail
Performance notes
Throttle assist runs the motor without pedaling and pedal assist responds to effort, so range falls faster when the throttle is used heavily. A hub drive pushes the rear wheel directly. Fat tires and dual suspension absorb impacts on rough ground.
