Your Top 5 Questions, Answered

One battery charge will last about 40-90km. The battery will last up to five years – or 1000 complete cycles.

Yes! The motor features regenerative braking, which recharges the battery while riding. Riders can select from four regeneration modes and the system automatically recharges when the rear brake is applied. On average, the battery’s range can be extended up to 15% on each ride. This setting is most useful in situations where you're going downhill, which will help control your speed and boost your battery!
