It took me a while to figure this one out. I've seen a variety of trikes that have been converted with hand cranks, and I automatically thought that's how this trike came about. But I saw some things the didn't make sense. What are those bars attached to the steering head that point down and to the rear for? Why is the front boom so high compared to the seat? What's that little wheel in the middle for?
I won't admit how much time I spent looking at the trike before I saw it in a different way. Suddenly I saw that it was not a converted trike. Instead it's a converted wheelchair. That's why it has the little wheels. Someone put a trike front end on a wheelchair.
