My "collection" of bikes includes all kinds. I have decided , however,to concentrate on 3 speed bikes . I enjoy riding and tinkering with them . I will still buy other bikes if I find some like I have in the past couple of weeks , like the $300-400 Mountain bikes I bought for $10 each, but am going to seek out more 3 speeds.I plan to dissassemble a 3 speed hub and put it back together , just so I know how. Anybody else into them? If so, what do you especially look for in a 3 speed bike, not that I'll pass up any of them if the price is right.Thanks
