About the author

About this conversion

A bike that had an old obsolete system fitted some years ago so we replaced that with a modern Bafang setup. Required some custom brackets for the batteries and display.

Extra parts and modifications used for this conversion

Motor Fitment

Motor fitted quite easily up front. Easiest part of the conversion.

Battery

2x DP5 battery mounted to custom brackets behind the seat. This took some work to build but the end result was great.
