Here's my urban bomber project. It started out as a kids wheelie bike that I bought from a recycling market but the back wheel wouldn't fit the Huffy Bronx I wanted it for. So after much looking and measuring I found a partly stripped mtb for $5 from the recycling market. The donor bike cost me $50 but Toys R Us still has them for $199. To get the back wheel to fit I cut the rear brake posts off. The rear wheel is 20x4 (?) and the front is a 24". Future plans are some paint and to lock the rear suspension. Hope you guys like it.
