Hope Ebike Crank Arm

Shorter crank arms like the 165mm are standard for e-bikes because they provide better ground clearance. This helps reduce pedal strikes when navigating technical, rocky terrain, allowing you to keep pedaling through obstacles where longer cranks might hit the ground.

These cranks use an ISIS spindle interface, which is common on many e-bike motor systems. However, because e-bike motor interfaces vary significantly, you must confirm your specific motor uses an ISIS spline before purchasing.

Yes. Hope designed these specifically to handle the higher torque loads generated by e-bike motors. They are built with a robust construction intended to withstand the added stress of electric mountain biking.

No, these cranks feature a standard 9/16-inch pedal thread, which is the industry standard for almost all modern mountain bike pedals. You can use your existing pedals without any adapters.

The offset is engineered to ensure the crank arms clear the motor housing and maintain the correct chainline. This alignment is critical for smooth power transfer and preventing the cranks from rubbing against the motor casing.
