The rear motor is currently only available for pre ordering Swytch Max+ kit. All other Swytch products are only available with front wheels. This product is not available in folding/narrow motors.
There are several factors to consider when looking at whether the Swytch Rear Motor is compatible with your bike.
Type
The two main motor types are freewheel and cassette. The Swytch motor wheel is a cassette motor wheel. The difference between a freewheel motor and a cassette motor lies in how the rear gears (cogs) are attached to the motor hub and how they function mechanically.
-
Freewheel Motor:
- A freewheel system has the ratcheting mechanism built into the cogset itself. The freewheel threads onto the motor hub using an external thread on the hub.
- The motor hub is threaded, and the entire freewheel screws onto it as a single unit.
-
Cassette Motor:
- A cassette system has the ratcheting mechanism built into the motor hub (called a freehub body).
- The cassette, which is a collection of individual gears, slides onto the freehub body and is secured with a lockring.
The key information to remember is that as long as you bike has 7 gears, then our cassette motor will fit. Single Speed bikes are not compatible, you will need to select a front wheel.
Size
Most common bikes fit our rear motor wheel - some smaller road bikes won't fit because of the size of the gap between the forks, our motor will fit 135-142mm fork gap. If you bike has 7 gears or more then it will likely fit into the gap between the forks. Sometimes this requires a little bit of force to get it into the gap, but don't overstretch the forks. If you have a hybrid, gravel or mountain bike you shouldn't have a problem with the size, if you have a larger mountain bike, you might need to consider a spacer. The Swytch rear motor wheel is compatible with both disc and rim brakes.

Hub Brakes/Gears/Dynamos
A key point to remember is that the Swytch wheel will replace your back wheel, so you will not be able to keep your hub from your current wheel - if that contains gears, a dynamo or the braking system - you will need to work out how to replace those elements if you still want to use them.
