Is the bottom bracket included?

What motor systems is this crank compatible with?

This assembly is optimized for use with specific SRAM/Brose and Bosch motor systems featuring an ISIS interface.

Do I need special tools to remove these crank arms?

No, the assembly features a self-extracting bolt, which allows you to remove the crank arm using standard hex keys.

Are the crank caps included?

Troubleshooting

Crank arm feels loose after installation

Audible creaking while pedaling

Ensure the bottom bracket interface is properly greased and the crank bolt is tightened to the specified torque value.

Pros and Cons

Pros

  • Easy maintenance via integrated self-extracting bolt
  • Optimized compatibility for major e-bike motor systems
  • Provides a balanced strength-to-weight ratio

Cons

  • Chainring not included in the package

Setup, Compatibility & Care

To ensure a successful installation, verify that your e-bike motor system uses an ISIS interface. The assembly includes a self-extracting bolt, which facilitates installation; ensure you have the appropriate hex key to torque the bolt to manufacturer specifications. Because the crank cap and chainring are not included, be prepared to transfer your existing chainring or purchase one compatible with your specific drive train. For long-term care, regularly inspect the mounting bolt for proper torque settings after the first few rides and keep the interface clean of debris to prevent creaking or premature wear.
