seriosuly? do you seriously want to do trials? in that case, seriously get a bike... seriously, if you ride a bmx at the moment, you will probably want to buy a mod - try an onza t-pro and if you ride a 26" mountain bike, you will probably want a stock - try an onza hitman there you go its best to ride other people's trials bikes though, a mod and a stock, so that you can find which one you want a mod is easier to learn on, says my friend, which is true unless you find them uncomfortable to ride, in which case its a stock, but he was really bastardy about me writing this so i did.
