She pulls like a bull. I won't let people ride it because it will take off without you if you are not ready for it. It will pull a wheelie if you're not careful too. I love it. Be out riding, cruising along at 15-20. Just minding my own business. The someone will try to do the race thing, I WOT and just boom 32. lol. I never timed it. It's fast to 32. Same thing going up hill. Be cruising 10-15 mph, then WOT, boom 30 mph, or you ride a wheelie and almost biff it, well me any way. I suck at wheelies. lol.
