ive been riding for about 6mnths now and over the last 2 to 3 mnths ive got serious about it. Ive had my gt moto around 3 weeks and progressed at jumping to about 3 - 4 ft jumps (i know it aint massive but im still learning) and i seem to have got stuck around the4 ft mark hows the best way to get bigger. Hope this post makes sense?
