Taps, Gaps and Side hops (TGS) are generally harder on a 24inch bike with street geometry its do able but harder that a bike with geometry for this, hops and pedals kicks are basically the same really its just that you have to do them in a slightly different way. The brakes on the Zoot are good just get the rims grinded and some good pads, but if you want to spend a bit of money on Maguras or a Discs go for it it can't hurt. You will need new hubs though, just go for a front disc and either keep the V at the back or get a Magura rim brake and get a Disc wheel for the front.
