Re: 24 m.p.h.???
i have a mongoose with 700c wheels a 66cc grubee and a 36 th sprocket. if you tuck down into the handlebars it will hit 40 mph but it's wound as tight as a cheap watch. it's all stock no mods with very few miles, checked by gps. i've found that almost any 66cc kit with a 44 th sprocket and 26" wheels wil do between 30-35 mph top speed.
