Special Lists

Every Grin conversion kit turns a regular bicycle into an electric one, built around a Grin hub motor with the matching controller, wiring, and options. Browse the kit families below to shop by motor.

Not sure where to start? Build a complete kit for your bike step by step in the kit builder, or check the compatibility guide to see which motors fit your frame. You can also compare performance in the motor simulator, browse real conversions in the project gallery, or if you're new to ebikes, start with our Start Here guide.

There are hundreds of parts that we've carried over the years but which we no longer offer for one reason or another. We keep an active list here to use as a handy reference for those who have older gear and may need to look up certain details or specs.
