Questions about the drive

Which bottom brackets is the Pendix eDrive compatible with?

The Pendix eDrive is compatible with all bicycles that have a standard BSA bottom bracket with 68 mm or 73 mm width. There is also compatibility with all bicycles with a different bottom bracket sleeve if this is slotted in the frame and tightened by two screws. For safety reasons, installation is only possible in bottom bracket made of metallic material (aluminium, steel). Plastic bottom brackets are not suitable. If you are unsure, contact your dealer.

How does the system operate when the motor is switched off?

The Pendix eDrive is equipped with a gearless motor, which provides a particularly low resistance cycling experience. The remaining pedalling resistance when the engine is switched off corresponds to that of a hub dynamo and is hardly noticeable.

Is the Pendix eDrive speed or torque controlled?

With a high-quality product like the Pendix eDrive, ensuring optimal drivability and a superior riding experience is essential. For Pendix, this means offering the most precise control over the desired level of assistance, along with a smooth and natural power delivery from the motor.
For this reason, Pendix uses a torque measuring bearing that precisely determines your pedalling force and regulates the motor accordingly.

How does the speed limit work?

The Pendix eDrive comes with a speed sensor attached to the rear wheel. Together with the wheel size set by Pendix in the electronics, the Pendix eDrive detects when the speed exceeds 25km/h and gently shuts off the motor support.

Can I keep the shifting and braking systems in my bike?

The Pendix eDrive is compatible with all derailleur and hub gears and with all brake systems; even back pedal brakes can still be used.

The Pendix eDrive is available with a crank length. This is 172.5mm.

How many chainrings are compatible with the Pendix eDrive?

You can use the Pendix eDrive with all single, double and triple chainrings.
