my mate james is a dirt jump rider and he learnt to pedal hop in 5 minutes He's 15 and seriously good on a bike, i tought him and he learnt it straight away, just like that. His max pedal hops on a trials bike is 45 in a row, he doesnt even have a trials bike! He has some balance im telling you!!! Getting back to the topic, anyway, how good is your balance? What i learnt was to stand still on the bike, then kick the front up hard and try and get the backwheel off the floor, if its off, you've mastered it! Good luck!
