The Shimano STEPS FC-EN500 is a dedicated e-bike crank arm set built for everyday riding through to more spirited adventures, pairing a clean, durable finish with the symmetrical stance Shimano STEPS drive units are designed around. Supplied as the left and right crank arms without a chainring, it is an ideal genuine replacement for a worn or damaged set.

• Genuine Shimano STEPS e-bike crank arm set
• 170mm crank arm length in a black finish
• Symmetrical 178mm Q-factor for a balanced, ergonomic pedalling position
• 24mm narrow bottom bracket spindle
• Chaincase compatible for fully enclosed drivetrains
• Supplied without chainring

Built for e-bikes

Unlike a standard crankset, the FC-EN500 is engineered specifically for the loads and pedalling feel of an e-bike, working with the Shimano STEPS system to deliver smooth, consistent power transfer. The symmetrical Q-factor keeps your feet evenly positioned for comfort over long rides and busy commutes alike.

Practical, low-fuss design

Chaincase compatibility makes the FC-EN500 well suited to city and utility e-bikes that run a fully enclosed chainguard, helping keep the drivetrain clean and protected. The hard-wearing black finish is easy to live with and quick to keep tidy.

Compatibility & fit

This is the 170mm crank arm set in black, supplied without a chainring. It uses a 24mm narrow bottom bracket spindle and requires a compatible Shimano STEPS e-bike bottom bracket. Confirm your existing chainring, chainline and Shimano STEPS drive unit are compatible before fitting; if you are unsure, contact Tune Cycles and we will help you confirm the right part for your e-bike.
