We offer a hub-only option, which includes the hub without the rim and spokes. This allows you to customise your wheel by threading it to a rim of your choice at your local bike shop.
The standard hub has 36 spoke holes (13g), while our folding bike hub has 28 spoke holes (13g).
See the below technical drawings so that you or your wheel builder can calculate the length of spokes you need to build your electric wheel.
