Stainless steel knurled replacement drive for Go-Ped brand Bigfoot scooters. 3.075 inch total length. Uses your stock 6x80mm spindle bolt(not included).
Stock spindle size is 0.625" diameter. Larger diameter spindle equals more top speed(to a point), but with slower acceleration. Too large of a spindle on a stock engine with a heavier rider will result in slow acceleration and slower top speed. Engine mods and rider weight have a big effect on spindle size.
