Does anyone have any knowledge of where I can find a used 24" wheel track bike. "For my 8 year old". Complete bike would be best but would consider a frame to build up. And what about wheels? These little suckers a tough to find. I've priced a Havnoonian but is a little steep for my budget currently. I keep an eye on eBay, but have not had any luck. Even tried eBay in several European countries. I'm considering a frame building school to build my own. Help me please.
