I can consistantly hop onto things that are bar height and I ride like 24s. Hopping over things that tall is scary but I can usually do it. The heightest thing I jumped over was this box at scooterzone maybe a little higher then bars. like 3-4 inches
went out and made like a hop measuring device lol nailed in a bunch of nails at different hieghts and put a stick on them, i did 30in. first try but then i stopped so im curiouse to see how high i can go
