No weld battery pack

I've been wanting to convert my vintage Cannondale aluminum hybrid bike to an ebike but with only minimal changes and using a design that did risk the integrity of the aluminum frame. No stress on either the front forks or the rear drop outs.

I thought I'd have to design and build my own friction drive and was well on my way to doing so. However, I am also a minimalist. I like to reuse and salvage items whenever possible rather than buying new.

One day when surfing salvage and recycling centers online I was lucky enough to find incomplete friction drive conversion kits from a Canadian manufacturer (Alizeti) that apparently went out of business.

Sad for them, lucky for me since I was able to acquire 5 incomplete kits consisting of the motor drive, the mounting frame and aluminum extrusion battery housing.

The units come with the main circuit board and bluetooth board, but without the controller that is needed to make the boards work together
