The bikes may be free, but the repair is not. All bikes are free to children who can't afford them. I replace warped wheels if they are bad or straighten them out if I can. New bearings and new seats are needed on some bikes. A lot of the bikes need painting, but I don't paint them.
Paint is too expensive.
The kids can paint them if they want. Hurl gets the bikes and parts from various places. Very often kids will bring him parts to trade for a bike. I gave them away. She told me to come get them.
