Hi everyone. So I've practically gone through almost every single type of bike. I was first interested in a mtb then realized I wont be doing ANY off-road riding at all. So I tried a hybrid and it was quite easy to pedal compared to the mtb.

Then I tried a cannondale quick 4(too small) and a Giant rapid 3(already sold). I liked them because they were more of the aggressive sportier side of the hybrids- and those two were even easier to pedal than a normal hybrid (giant seek, crosstrail, etc).

My main purpose is to get more in shape and get in extra cardio while I train for running: marathon, 5ks, 10ks, etc.

So I've come across the Giant Rapid 3, Defy 3 and a used/like new 2011 Jamis ventura sport at my local shop. I didnt ride the Defy 3 as they didnt have them but ordered one for me to try.

I want to get some feedback on the Ventura. Is $500 a good price? They cleaned the bike up, replaced any work out parts, etc. It looks brand new IMO. It ran nicely and I liked it, but I wanted to try the Defy 3 to compare.

Defy 3 is $720. http://bikeworks.com/product/giant-defy-3-72339-1.htm
Rapid 3 is $620.http://bikeworks.com/product/giant-rapid-3-72380-1.htm
Ventura brand new is $624 http://bikeworks.com/product/jamis-v...rt-74678-1.htm

I'd like to get your feedback as far as what I need to look for, and which would be the best buy and if the ventura is worth the price, even though its used. I need to find out if theyll still honor a warranty as if it were a new bike.

Would appreciate the help and if any can give more advice I'd surely appreciate it!
