Presentation
The SHIMANO STEPS FC-EM900 crankset in black finish is a crank set designed for STEPS-equipped electric-assist bicycles. With a crank length of 160 mm, it aims to offer pedaling adapted to the specific requirements of an EAB: pedaling assistance, torque constraints and intensive use. This version is supplied without a chainring, allowing you to keep or choose a chainring compatible with your existing configuration.
User benefits
This crankset for electric bicycles can be used to replace worn or damaged cranks for a healthier transmission and smoother pedaling. The 160 mm length may also suit users looking for more compact pedaling kinematics, depending on frame geometry, ground clearance or pedaling preferences. And if your chainring is still in good condition, the chainring-less design makes it easy to upgrade without changing the entire drivetrain.

Expert advice
Before purchasing, check the reference of the crankset currently fitted and the crank length (160 mm) to avoid any difference in pedaling position. If you're re-using your chainring, check its condition (teeth, web, fixing) and replace it if wear is marked, to preserve the chain and transmission quality. When assembling your chainring, respect the tightening torque recommended by the manufacturer, and check it after the first few rides for play, tightness and alignment, to secure the drivetrain and limit premature wear.
