Best Mid-Drive Electric Bike Kits

I have put together a table of useful links featuring the most popular mid-drive electric bike conversion kits currently available.  The products listed below are from Bafang or Tongsheng – the current market leaders in plug-and-play mid-drive motors.  If your DIY e-bike build is on a tight budget there are also plenty of cheap electric bike kits available that utilise direct drive or geared hub motors.

For my UK and international visitors there is product table of links to suppliers that I personally use on Aliexpress for Bafang and Tongsheng mid-drive motor kits. I have been dealing with these suppliers for nearly three years and I have always received an excellent service.

My preferred battery supplier is UPP (UnitPackPower), I have found their customer service to be second to none and I have only had a couple of minor issues with their batteries out of well over a hundred purchased.

I have listed various options for the Bafang mid-drive and the Tongsheng TSDZ2 . These motor’s continue to be popular, with Bafang being the more established brand of the two.

For more information on these kits, check out my electric bike kit reviews section. If you are still undecided as to whether to go for a kit or purchase a ready-made e-bike please see my electric bike or conversion kit post.

Please read my reviews of the kits prior to making a purchase. Although these motors are generally reliable, they can sometimes be problematic, and installation is not always straightforward. The other thing to consider is ongoing maintenance, most mid-drive motors will require some servicing or replacement parts in the long-term. If you are buying one of these motors it would be good to familiarise yourself with the inner workings of the motor in question.

 

Thankfully both the Tongsheng and Bafang have a good availability of replacement parts, from controllers through to primary gears and speed sensors. I will be compiling a pricing chart for these as well.bafang bbs02b electric bike conversion kit

Battery selection

Choosing the right battery for your build is important, as you will want one that has a suitable range for your particular needs. In my electric bike batteries explained article, I show how you can calculate the approximate range of a given battery. I have also compiled a comparison table for all kinds of electric bike batteries from 36v10ah all the way up to 52v17.5ah.36v 17ah ebike battery

Spare Parts

Thankfully there is a good supply of electric bike parts available, so should you ever run into any problems, there is usually a solution.

Installation

I have provided a PDF installation guide for the Bafang, and there is a Tongsheng installation video below.

Alternatively, If you live local to me (I am based in South East Cornwall, not far from Plymouth), I can offer an installation service – Electric Bike Conversions South West.
