Foldable Bike owners read the instuctions!
I bought the kit to mount on a foldable bike that I often take with me in my airplane. Having not done my home work on your website I discovered the fork distance on this type of bike is too small (3″) to accommodate the 3.9″ wheel supplied. After some fork spreading (with my car’s jack) and filing the openings, things did work out. With a 20″ wheel there is a lot of power from the motor. I am well satisfied but it would be an advantage if there was a quick disconnect for the battery (instead of the screw on) making it much easier to fold the bike and put it in a car or airplane with the battery removed.
