Once you know your price range, try all the major brands in that range. They will all be fairly similar. The differences will be gearing, geometry, tire size. Also find out the weight of the bike. The weight may vary by 5 or more pounds. Depends on frame size. You will probably like some bikes better than others. I recommend buying the one that you like best. I agree that you should try more bikes. It seems like you will have no problem finding a bike you like!
