Hope Ebike Crank Arm Set

These cranks use the ISIS spline interface, which is common on many e-bike motors, but you must verify that your specific motor system utilizes an ISIS interface before purchasing. They are not compatible with systems using square taper, Bosch Gen 4 (which uses a proprietary ISIS-like interface but often requires specific offsets), or other proprietary standards.

Shorter 165mm cranks provide increased ground clearance, which is critical for e-bikes that often have lower bottom brackets and higher torque output. This length helps you avoid pedal strikes on technical, rocky terrain while still allowing for an efficient pedaling cadence.

Yes. These crank arms feature a standard 9/16-inch pedal thread, making them compatible with the vast majority of modern mountain bike pedals on the market.

Hope engineers these specifically to handle the higher torque loads generated by e-bike motors. They are built to be significantly stiffer and more robust than many stock alloy cranks, which helps improve power transfer and durability under heavy load.

You will need an ISIS-compatible crank puller to remove your existing cranks if they are also ISIS-based, and a standard hex key set for installation. It is also recommended to use a torque wrench to ensure the crank bolts are tightened to the manufacturer's specified torque settings.
