eZee Conversion Kit

High-quality, high-performance with many options

Using the same powerful and reliable electric motor and battery system found on the eZee bikes range, the eZee kit converts your bicycle into a state-of-the-art electric bicycle. Uniquely, this kit provides a configurable control options that combine throttle control (great when starting) with adjustable pedalling assistance (great when cruising).

If you have a suitable bike, installation can be done in a few hours with basic DIY skills and a set of bike tools. However, we always recommend that this work is carried out or at least checked by us or a competent bicycle mechanic for safety and for the best ride possible. eco-Bikes can assess your bike for suitability and can install this conversion kit for you. We have fitted kits for many happy customers.

To give this kit a thorough test, our partners at Glow Worm Bicycles fitted this kit on a large Kona Ute cargo bicycle and rode it from Canberra to Melbourne through rain and frost without a hitch (read more).
