Our kits are supplied with everything you need to convert your bike, however there are some accessories available that could improve your riding pleasure. The Narrow/Wide chainrings offer improved chain retention and a choice of 36,38,40 or 42 teeth, while the twist grip throttle is an alternative to the thumb throttle included in the kit. If your bike has hydraulic brakes we offer a couple of solutions. The first is a set consisting of reed switches and magnets which are a generic item and are cost effective. The second solution is a complete hydraulic lever with built in cut-out switch at a very competitive price.
