Kids cycles are chosen by wheel size rather than by model, running from small ones with training wheels up to 20 inch frames for older children. Because children outgrow a cycle in a year or two, most parents in Karachi buy second hand and sell it on when it gets too small. That turnover is exactly why used kids cycles in good condition are easy to find here. For older kids ready for a bigger frame, see BMX Bikes or Mountain Bikes.
