Are these bikes worth it?
 

I have a couple of bikes I'm looking at and was wondering if they are worth the asking prices, the first is a Giant Boulder (cro-mo frame) in decent shape, needs some TLC but not too bad overall-$180, not sure of the year model. The other is a Diamondback peak that is supposed to be almost new for $100. The Giant fits me OK, is just a little bit tall for my likes but would fit with a little shorter stem. The Diamondback is a Medium frame. I know neither is a high end bike but would do if the deal was right.

Everyone here is going to tell you to spend a little bit more and get a better bike.

Last steel Boulder was a 2002; and only the seat tube was chromoloy - - the other tubes are hi-tensile steel (read: heavy) and had a rigid fork. $180 seems high to me.

If the DB has a suspension fork (Suntour?) it's newer and should be an aluminum frame, right? If that's all the case, I'd go for the DB.

If you have to ask, the answer is probably "no".
