Re: can anyone make a living with this hobby?
That's why I'm reluctant. If you built it yourself then you have some mechanical experience. You develop all the quirks and it's truly individualized to you.
People want something you can just hop on and go like cars without tinkering with it at all. Then when something comes out of adjustment something happens then person walks away with the feeling these things are death traps. Ralph Nader would have most definitely put these bikes in that category.
You have found the fountain of youth. Ride and forever stay young.
