Hub Motor Specs for Hub Only Kits

We offer customers a hub-only kit option (motor not built into a wheel). This allows you the freedom to convert a usual size wheel which Swytch does not offer as standard. It also allows you the flexibility to build the motor into a rim and spokes of your choosing to match the aesthetic of your bike. 

The standard hub has 36 spoke holes,  while our folding bike hub has 28 spokes. 

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. 


Universal Hub Motor (100mm fork space) 






Folding bike Hub Motor (74mm fork space) 




Some example lengths of spokes for various wheels are listed below.
