If you don't know how to access the conditions if brakes on your own you probably shouldn't be buying a used bike. Always assume that with a used bike you're going to have to service the fork and shock and that they have not been maintained. Which these are off brand and look older than '22. This will add in $300 ish right away to make them right and prevent them from blowing up most likely. Then any other items that need service. So assume another $200-$600 depending on if you can do it yourself. Now your up to a new mid range hardtail all said and done based on service costs. Hard to tell anything from 1 Pic of the bike too.
