Walk assistance and hill start assist

Hold down the minus button and start walking: Walk assistance makes pushing your eBike that much easier. With hill start assist, you can set off more easily – without unintentionally rolling backwards.

Optimal support

Auto mode ensures you get the right level of support automatically. Such as if you lose speed due to climbs or a sudden headwind, for example. This makes riding your eBike even more enjoyable.

Limit mode
