What Makes the Shimano Deore XT FC-M8150 the Right eMTB Crank Arm Set?

The Shimano Deore XT FC-M8150 is a purpose-built e-MTB crank arm set engineered specifically for Shimano STEPS EP drive units, using Hollowtech II hollow-forged aluminum arms that deliver exceptional stiffness and strength at low weight. The integrated design eliminates motor spacers and fits flush against the EP drive unit for a clean, rattle-free installation -- a detail that matters on rough terrain where vibration amplifies any looseness in drivetrain components. At 160mm, this arm length is optimized for the higher bottom bracket heights typical of full-suspension e-MTB frames, reducing pedal strike on technical terrain.

Compatible exclusively with Shimano EP801, EP800, and EP600 drive units. Not compatible with non-STEPS motors or standard MTB cranksets. Sold as crank arms only -- no chainring or bottom bracket included. Requires a Hollowtech II compatible bottom bracket for your frame's shell standard. MPN: FC-M8150.

FAQ

Is the FC-M8150 compatible with any e-bike motor?

No. The FC-M8150 is compatible only with Shimano EP801, EP800, and EP600 STEPS drive units. It will not fit other motor brands or standard MTB crankset interfaces.

Does a chainring or bottom bracket come included?

No. This is a crank arm set only. A compatible Shimano e-MTB chainring and a Hollowtech II-compatible bottom bracket for your frame standard are both required and sold separately.

Why 160mm for an e-MTB crank arm?

E-MTB frames often run higher bottom brackets to accommodate the motor and provide better ground clearance on technical terrain. A shorter 160mm arm reduces pedal strike risk while keeping the effective knee extension angle within a comfortable fit range.

Best For

E-MTB riders on Shimano EP801, EP800, or EP600 drive units who want XT-quality crank arms at 160mm for full-suspension e-mountain bikes running technical trail or enduro terrain.
