Who should buy it
This bike fits riders who value a lighter e-MTB and don't need long range. It is also for those who prefer a standard pedelec without a throttle. If you ride short distances and charge often, it could work.
- You ride less than 39 km per charge and can charge at work or home.
- You want a lighter e-MTB to lift or maneuver.
- You don't need a throttle or a step-through frame.
Look elsewhere if you need long range or strong hill climbing. The unlisted torque is a concern for steep terrain. Also, the warranty is not published, which adds risk.
