Some people collect watches, some collect shoes, some collect cars or BBQ kettles. I just collect bikes. At least they keep me happy, fit and don't make me fat. lol
I have a few bikes anywhere between 15 and 33 years old. Nowadays I only buy used bikes. I try not to spend more than $200 to $300 on a bike. I fix them up and enjoy riding them. Some I keep, some I sell again. Constantly looking for a cheap cool bike I like to ride and tinker with.
