About this part
Replacement crank arm for Heybike e-bikes, sold as a single arm. It is available as a bare left arm, or as the right arm with the chainring attached, so you can replace only the side that is bent, stripped or worn. Fitments cover the Mars, Ranger S, Cityrun, Explore, Brawn, Ranger, Race Plus, Race Max and Sola.
Select the side from the Size option and your bike from the Fits bike option. A left arm goes on when the pedal thread has pulled out or the arm is bent; the right arm with chainring is the one to order when the chainring teeth are hooked as well. Fit the arm tight on the spindle and recheck the bolt after the first ride, since a loose arm rounds the interface and cannot be saved. The left pedal is reverse-threaded when you move pedals across.
