You also have to be careful if you buy a bike with a suspension fork, which personally I think those forks are useless unless you plan on doing downhill racing, that you don't spend $800 or less for a bike and get a tank for a fork that does not respond fast, is extremely heavy, and won't last long, then to replace it the darn new one will cost nearly as much as a new bike, not to mention taking watts away from powering the rear wheels efficiently which will then simply tire you out faster.
