In order to choose the right kit or a specific part for an electric bike, first of all, you should familiarize yourself with their parameters and features of work.
Components for electric vehicles include many kinds of products. These are the wheel motor and electric motors, controllers, controls and instruments, wheels, rims, spokes, transmission elements.
Buying components for electric transport is required in two cases: when replacing parts that have failed and when designing various vehicles on your own.
When replacing components on an electric vehicle that has failed, on the one hand, everything is simple: the same parts are selected and then installed. And the difficulty lies in the fact that original parts for rare and old models of electric bicycles, electric scooters, especially if they were in use and imported from Europe, are almost impossible to find.
