I have another question on behalf on hubby, can you buy a wheel with a 350w motor without buying the rest of the kit, he has his own e/bike but the kits on a 28inch wheel and he wants to buy a different basic bike and transfer the electrics to it but on a smaller wheel base if that makes sense. Can you buy just the wheel and motor, thanks

many thanks, I assume that the motor size has to be the same as the exhisting one to tally with the current electrics which is an Eezie bike kit and would any of those be ok or is there something else to add to moving the kit to another bike

You spec the wheel size in the text box of the order form - at the bottom of the page in this example.

The wheel size needs to be the same as the other wheel on the donor bike.

Choosing the rpm of the motor is a bit more complicated, depending on whether you want speed or torque.

This is what BMS says about it: "High speed means low torque. Low speed means high torque. RPM means "Revolutions Per Minute". 201RPM is often used for 24", 26", 700C and 28" rim. 328RPM is often used for 16", 20" and 24" rim."
