A:Answer depends on the age, its pretty big and seems to be a good size for adults , I'm 6ft 1 and 165lb and I never felt it was crammed or small , the handlebars go about 3-4 inches above my waist couldnt tell you exactly how tall but id eastimate 4-4.5 ft
dont quote me on that, it doesnt go that fast either its not too risky for a kid around 12-14 but I dunno about younger ones
