Warranty Limitations

Maximum speed. In compliance with the applicable European regulations for electric bicycles with pedal assistance, our kits are limited to a maximum speed of 25 km/h. Breakdowns resulting from the user's modification of the maximum speed parameter will not be covered by the kit's warranties, therefore, in order to ensure safe use, we discourage manipulation of the kit's factory values.

NOTE: The data on range (km) and maximum speed (km/h) given in this product are estimates because they depend on at least three factors:

  1. Rider weight
  2. Unevenness of the terrain
  3. Average driving speed

For longer range and battery life, a moderate level of assistance is recommended.
