The battery can last up to 120km on a single charge, depending on riding conditions, terrain, and rider weight. In eco mode, you can extend the range even further.

The maximum assisted speed is 25 km/h, complying with EU electric bike regulations. You can pedal faster if you wish.

Can I ride in the rain?
