Hello,

I Decided i would like to get a mtn bike (mostly for excercise) and have been reading lots of reviews and lurkin the forums for a few weeks. I will be using the bike almost completely for street riding. this will be my first bike since BMX like 10 years ago. Im 5'10 around 150lbs, i want something reliable , fun to ride and as LIGHT as possible.

these are the bikes so far im interested in, the cheaper the better, but i would pay more if it will mean ill pay less later in upgrades / repairs.

05 Rockhopper - 500.00
05 Hardrock Comp Disc - 550.00
05 Trek 4500 - 460.00

Any suggestions of which of these would be best for someone like me?? also any idea what frame size i should get? Do you know which of these weights the least?

Thanks!
