Thanks for the inspiration! A DYI project may be in our future...though not likely as a first bike.Here is a 20" folding bike that I installed a tongsheng mid drive. This one weighed 40# including the 36v 10ah battery in the seat bag.
Easy conversion if your husband knows his way around a bike, inexpensive, works great and can be put on a bike that you might already have and like.
I've done this conversion 6 times and soon to become a 7th, just because I already had the bikes - and loved the performance each time.
