Practice, Practice, Practice That is what you do took me about a day to start hoping on back wheel and a month to master it so i can go backwards, forwards and side to side but you will get there we all do.
Your best trick (your show off trick ) you know the trick that makes you you Mine was a 180 to the back wheel and do a gap. I up graded it to a 180 gap back witch is, you start on the back wheel do a gap and turn 180 in the air land on the back wheel and gap back to where you started from without any planting hops. Now i,m trying to do a 360 to the back wheel and do a gap iv only pulled it off 5 or 6 times so far maybe more
i bin riding with 35 to 40 psi for 17 years it works for me but it depends on your style of riding you could be a hard rider or soft rider so start off about 35 its best i think then let it down a bit
