i have been interested in fixed gear bikes for a while. ive heard that they are great for losing weight and help you develop more efficient pedaling. but as ive ridden bikes with free wheels (allows to coast? i am new to bike jargon) im not sure if i will like fg. Also ive always ridden hand me down bikes so i cant justify in my own mind spending $300-500 on a bike that is supposed to be bare bones, the simplest that a bike can be. any ideas for a cheaper fg? im not great in the working on my own bike dept unless its your basic stuff. could do with some convincing haha.
