The FFFixie is a cool bike designed for kids with 24 inch deep V rims. It comes as an urban single speed that can transform into a track bike using the flip flop hub. Every kid who can ride and who tries a FFFixie, loves it. It has a stand over height of about 630mm at the center of the top tube. Its flip flop hub makes for simple riding without the added weight of gears. This is the bike for in-betweeners (8yo to 12 yo) who have outgrown their kiddie bikes or who want some more speed than their BMX but don't yet fit adult sized bikes.
