Overview
A 26 inch electric mountain bike with a 500W motor rated to 749W peak, a 48V 374.4Wh removable battery, and five distinct riding modes including cruise control and walk assist, SGS certified to UL 2849.
The five mode system is the standout spec here, most e-bikes in this range offer PAS and throttle only, this one adds a walk assist mode for pushing the bike uphill and a cruise control that holds a set speed. Range splits clearly by mode in the listing: 22-25 miles on throttle alone versus 44-50 miles with pedal assist doing part of the work.
- 500W motor, 749W peak, up to 19.8 MPH
- 48V 374.4Wh removable battery
- 5 riding modes incl. cruise control and walk assist
- 21 speed drivetrain, front suspension fork
Who it's for
Suits a commuter or trail rider who wants mode flexibility, walk assist for steep pushes and cruise control for longer flat stretches, over a bare bones throttle bike. Less suited to someone wanting a plug and play bike straight out of the box, since it arrives 90 percent assembled.
Strengths and trade-offs
Drawn from this product's published specifications.
- Five riding modes including cruise control and walk assist
- Removable 48V battery for indoor charging
- UL 2849 certification, SGS validated
- Front suspension fork and disc brakes
- Arrives only 90 percent assembled, some setup required
- No customer reviews yet to confirm real world reliability
Performance notes
The 500W motor with a 749W peak rating reaches close to 20MPH, and the front suspension fork plus grip pattern tires are aimed at gravel, hillside, and back road terrain rather than technical singletrack. The 21 speed drivetrain covers the climbing range the motor alone would not.
