Tools:
Only basic tools such as screwdrivers, hex keys.etc are required for fitting however you will probably need a bottom bracket removal tool and crank puller to remove your bike’s original hardware before you can install the motor kit. You may also want a chain breaker tool if you need to alter the size of your current chain.

You will also have to lengthen the chain by adding additional links to fit the larger 42tooth front gear. I ended up purchasing another chain to extend my original one
