i have an 8 year old daughter who rides a dirt bike. she wears all safety gear and rides with outriggers in a cirlce in the yard. she has a pw50 so we use the screw to make the dirt bike slower.
I'm looking to buy one of these ( http://www.ghostracingseries.com/ )specialoffers.htmpocketbikes for my brothers birthday but I'm not sure if I should buy a Mini moto or a Midi moto - what do you think?
