It needs engine work. Was ported and polished, rocket key, race pipe, re-geared. GPS tested at 37.5 mph. Supposedly poor oil/fuel mix on my part, but I suspect porting issue,not sure don't care to check myself, parts are all online for it. Was a blast to run though literally only has like 40 minutes on it. Got 2k into it will take 1k for it. Was a fun toy to get around on when OTR. Used about 3 hours before mods and like I said 40 min after. Warning this will not work for your kid as a toy,i weigh 165 and literally had to stand on front end and lean forward to keep the front end down, it is ridiculously powerful. Disc brakes front and rear aluminum frame american made. Check out Go-ped website for info on there stuff.
