if you buy this bike i have a tip for you, you have to check to see if the angry donkey have been removed from the bike, its well know in these sort of frames. here's how to do it
Remove your rear shock and run your rear end through it,s travel gently. The action should be smooth and consistent and should require any real force. If it,s not consider how much better your riding experience would be if your frame wasn,t a cross between a donkey and a pogo stick with wheels, EEEE AAAWWW!!.Get it sorted and keep it pinned or hold on tight it,s gonna be a rough ride and a hard landing. EEEE AAAWWW!! Angry donkey strikes again!
