I had a three-wheeled recumbent, the low slung kind that you kinda sit in instead of sit on. I enjoyed it a lot, but I only recommend it if you could ride in an area without cars. Riding on a city street feels like tempting death.
The bike I am about to modify was made by Schwinn, its an electric chopper that was made without doing any proper market research. Basically, they targeted kids, but there was not place in the US where they were legally allowed to ride them 10 years ago. I was able to pick one up new for just $200 (though used ones are sold for a lot more now). They also were originally sold with an under-powered SLA 24v system, which made them very slow. Fortunately the underlying electronics and hub motor were capable of handling a36v 10ah LiPo4 battery pack. That was good enough to make it a fun toy to take the kids zipping around a parking lot with, but I've been wanting to upgrade the motor to something over 1000w for a while. With 1200w & 52v system the top speed will be about 27 - 30mph, I'll probably never take it that fast.
The bike attached is not my bike (that one is a slightly smaller frame), but it may look something like that when I put the new pieces on.
