How to choose a chainring for ebike conversion ？
For a normal pedal bike without electricity, small chainring is more compatible with mountain bike which can help you climb easier. Big chaining is more suitable for city bike, road bike and foldable bike which can help you enjoy faster speed .
However , now you are converting a bike to an ebike with motor, the size of chainring won't influence much because there is enough power for you to ride. When you install a mid motor on your bike , the bigger the chainring is , the faster the speed wil be. And please note that the chainring is more compatible with a bike ≤9 speed. If you are not sure which chainring you should use, you can consider the same teeth as your original chainring.
Brake Lever or brake sensor ？
The brake lever we send by default has a power-off function. We provide you with some tips on choosing the appropriate braking system options.
If your bicycle braking system is a mechanical disc brake or a wheel V-shaped brake, you can choose the brake lever option.
If your bicycle braking system is an integrated thumb shifter, it is hydraulic braking, or if you want to keep your own brake lever. You can choose the brake sensor in the BAFANG mid wheel drive kit.
