Please see Specs section for compatibility information as chainring compatibility depends on motor type

Use this to replace your old or damaged chainring. The chainring on an electric bike is the front sprocket that engages with the bike's chain and transfers power from the rider or the electric motor to the rear wheel, determining the bike's speed and efficiency.

Ultra Compatibility: For use with Bafang Ultra mid-drive motor; Ibex, Jeep, Rubicon, Ridgerunner

Please note, the spider for the Ultra motor chainring is sold separately here and requires special tools to replace. It is best to visit a local bike shop for this replacement. 

For hub-drive bike models, see the Hub-Drive Crankset Replacement.
