Probably worth it to spend a little time searching the forums, no surprise that this question comes along pretty much weekly - and a lot of folks have chimed in with tons of advice. But, they're not going to retype the advice every time - so, spend a little time on terms like "first bike" and "help me choose" and phrases like that. Quick takes for you: 1. know in advance your long-term maintenance and repair plan. a local bike shop (LBS) is a legit plan. taking it back to a big-box retailer is not a plan. self service is a plan. 2. be realistic about your budget, and do NOT go cheap. cheap catches up with you in the long run. investing "up" pays you back in longevity, reduced maintenance, even resale. 3. the best bike is the one that calls to you to come and ride. you love the bike, that's the one. don't love the bike, there it sits. 4. get the help of someone, or do the research yourself, to make the bike fit. an incorrect fit violates rule#3 above.
