Engine S1100/S2100 cassette drum

The motor cassette drum is a key component that allows mounting the gear cassette to the electric motor on the bike. For S1100 and S2100 motors, the cassette drum is specially designed to perfectly fit these models.

The cassette drum serves several important functions, such as:

• Enabling the attachment of the gear cassette to the electric motor
• Ensuring the proper operation of the derailleur system on the electric bike
• Protecting the motor's interior from dirt and damage

When choosing a cassette drum for S1100 or S2100 motors, it is important to ensure that it is compatible with the gear cassette used on the bike and with the selected motor model.
