I'm not a biker. I do however like my Trek 4900. It's aluminum, light and gets me where I want to go. I did put some smaller tires on it (1.75" wide) and got rid of those stupid tiny valve stem tubes.... I like the front shocks. I hate rear suspensions when powering up hills. I hate the seat, but I have yet to find one that doesn't make my ass and crotch ache for days. I think it was about $500 new.

A buddy of mine has a $4000 mountain bike. I hate it.

I think I just like my KX 250 too much to get into peddle bikes.
