Absolute bargain mate! Seeing as your starting out, dont bother going overboard with upgrades, just make sure things like contact points (pedals, handlebar grips, brake levers) are all decent enough, as you'll appreciate those the most. And a decent set of rear brake pads too, and you'll be flyin'! And as for tyres, seein as thats a 20inch rear wheel, Onza StickyFingers are your best bet. They do a 20in rear, instead of having to run a lighter, thinner 20in front tyre like a creep crawler Welcome aboard
