what's a good manufacture to get a bike from?? My boyfriend was talking about a trek. Is that a good kind? Does it really matter? I"m looking into riding trails and stuff like that, no street riding. so does it matter what manufacture i go through as to which ones have good quality. Plus i don't know if i really want to do this for a long time or what? i don't know if i'm gonna stay with this or not. so yeah...any suggestions?
