Strong engine!

The strong, durable 36-volt front-wheel motor with 50 Nm provides perfect support, which together with the removable and powerful lithium-ion battery forms a perfect team. To protect the battery, the integrated BMS (Battery Management System) always ensures an optimal energy supply

LCD bike computer!

The 5 support levels of the motor are controlled via the easy-to-read LCD computer. It also provides important information such as the current battery capacity, route information, speed and much more. The engine power can also be completely deactivated.
