Product description
The SHIMANO STEPS E-MTB FC-M8050 crankset in 175 mm length (without chainring) is a crank designed for all-terrain electric bikes equipped with Shimano STEPS motorization. Designed for e-MTB use, this crankset contributes to smooth power transmission between pedaling and electric assistance, while facilitating maintenance or replacement of wearing parts thanks to its "chainringless" configuration.
Benefits for the user
This e-bike crankset can be used to replace a worn or damaged crank on a compatible electric mountain bike, to restore stable pedaling and good continuity of assistance. The "without chainring" format is particularly useful if you want to keep your existing chainring, or if your configuration requires a specific chainring (fitted according to your transmission), without multiplying unnecessary purchases.

Expert advice
Before purchasing, check the crank length (175 mm) to maintain your pedaling position and avoid any change in behavior (ground clearance, cadence, comfort). If you're replacing a single crank, check the condition of the other side and that it's tightened to the torque recommended by the manufacturer. When reassembling, also inspect the chainring (not included) and associated hardware, to avoid any play, noise or premature wear on your electric mountain bike.
