Since the only one in the family who didn’t have an electric bike was my wife I of course had to build one for her as well. When asking what the battery should look like the answer was “It should look like it’s kind of floating in the frame”.. Well..

I had to use the mill for this one, milling 10mm acrylic spacers to hold the edges of the battery pack. Since my beloved wife doesn’t do much offroad racing this’ll be plenty strong enough.

Designed a box shape that follows the frame with an offset. This is a test fit of the outer casing, seems quite ok.

So, after welding a 13s5p pack of LG MJ1 cells the bike turned out quite ok.

The bike is propelled by a BBS02 motor using an eggrider display and performs real good. This motor previously had a problem with the controller where it would say the battery was depleted when it was almost full, but with the eggrider this seems to work just fine.
