E*thirteen e*spec Plus Ebike Crank Arm

No, these crank arms are specifically engineered for the Shimano EP8 motor interface. They will not fit other e-bike motor systems.

A 160mm crank arm length is popular for e-bikes because it provides increased ground clearance, which helps reduce pedal strikes on technical terrain. It also encourages a slightly higher cadence, which can help you stay in the motor's optimal power band.

The installation is very similar to standard cranks, but you must ensure you are using the correct tools for the Shimano EP8 splined interface. If you are not comfortable working with e-bike drivetrains, we recommend having a professional mechanic perform the installation to ensure proper torque specifications.

The e*spec Plus cranks are built with a focus on durability to handle the higher torque loads of e-bike motors. While they are a performance upgrade, their primary benefit is the combination of optimized geometry for e-MTB riding and robust construction rather than just weight savings.

This set includes the crank arms themselves. You should reuse your existing self-extracting crank bolts or ensure you have the correct compatible hardware for your specific Shimano EP8 setup.
