Information about your base bike

  • What size wheels does your bike have?
  • Shall the motor be installed to front wheel or rear wheel?
    • Installation into the rear wheel is recommended, if possible, due to a higher stability. If your bike is equipped with a gear hub, it does not make sense or is impossible to install the motor in the rear wheel.
    • When installing a front wheel motor please note that an existing hub dynamo might be dispensed with. The installation of a suspension fork is usually possible without problems. Lightweight suspension fork are excepted.
  • Which material is your frame made of: Steel, aluminium, certain types of lightweight material (magnesium, carbon)?
  • What type of brakes does your bike use: V-brakes, disc brakes (hydraulic or mechanic) drum brakes?
  • Desired rim colour: Black or silver?

Conformity with German road traffic licensing regulations

  • Do you want your bike to stay in conformity with road traffic licensing regulations (pedelec)?
  • Or do you want it to have a higher speed or more power (e-bike)?
    -> You want to apply for registration and use your bike with a license plate and insurance
    -> You want to ride in areas where German licensing regulations do not apply.


  • In what kind of terrain do you wish to ride your bike: Flat land, hilly areas (how may % of incline)?


  • How many km/mls do you want the motor support to last? Range can be increased by battery capacity almost endlessly, but the battery will become larger and heavier.
