Hub Motor Stuff - Ebike Parts

Hub Motors

We carry a very wide assortment of front and rear hub motors for just about every need. From the tiny G311's to the mighty RH212. All our motors are unlaced and can be hand-built into a rim of your choosing. Most motors are available in at least two different winding speeds as well.

Motor Hardware

Parts to keep your motor running.

Rims

32h and 36h rims for your wheel builds. All of our hub motors have 36-hole flanges, except for our own Grin All-Axle motor, which is 32 holes.

Spokes

We sell custom length Sapim Strong and EStrong (12-13g) single butted spokes in both black and silver, for all your hub-motor specific wheel building needs.

Freewheels and Cassettes

Almost all Grin-supplied hub motors now use Shimano-HG compatible cassette freehubs. We stock these in 7-10 speeds, and also carry a range of screw-on freewheels with small 11T cogs for people using older/cheaper hub motors with the threaded freewheel mount. Not sure of the difference? Sheldon Brown can tell you.
