Racing bikes are the original BMX bike, created during the 1960s as kids began to ride on dirt tracks, punishing their store-bought Huffies and Schwinns. BMX bikes are sturdy and heavier than the other two types of BMX models. They have upright handlebars to provide riders more control. They feature lighter wheels and thinner tires with knobby treads to help add more speed while providing more traction. Finally, racing bikes have rear brakes only, to prevent bikers from going over the handlebars during crowded races. The brakes are the linear-pull type, which provide the most stopping power.
