14" bikes aren't all that common but the Pump fills an important role in the BMX lineup, sitting perfectly between 12" and 16" bikes it's designed for younger riders.
Kink designed the Pump 14" with proportionate geometry and components suited to this age and height rider, small details like Mission Micro brake lever and the reduced angle of the Weider seat are carefully considered to ensure everything is of proper fit and function on this bike.
