Electric Bike Parts

The chances are, if you build a DIY e-bike, at some stage you will need a reliable source of electric bike parts.

Fortunately, now the industry has been going for a good few years there is an excellent choice of replacement parts, covering anything from a Bafang controller through to LCD displays, pedal sensors, motor parts and so on.

As the demand has increased, so has the availability.  Sometimes it can be challenging to find all the parts in one place, so I have compiled the table below to make things a little easier.

The parts will be listed in the order below, starting with Bafang parts. I have compiled a separate table for electric bike batteries.

The parts tables below contain links to trusted sellers on Aliexpress – I only promote suppliers that I have used myself.

Most of these suppliers offer low-cost global shipping and in some cases free shipping.

I receive a small commission for each sale referred through this site and you will not pay any more or less than if you had visited Aliexpress directly.

By purchasing through these links you will be supporting the continued development of ebikechoices.com.
