Big-name contests such as the X Games showcase BMX biking as a main event. In the early days of the sport, bicycle motocross centered around races that took place on downhill courses. Since the 1970s, BMX has broken into numerous disciplines, including street and half-pipe. The BMX features unique specifications compared to more conventional bicycle models.
BMX Frame
The compact frame offers increased handling for high-speed BMX tricks. Compared to the mountain and road bike, the BMX frame sits lower to the ground. The hollow-frame tubes help to decrease the overall weight of the BMX. Top-rated BMX frames are constructed of lightweight alloys and metals. The lightest BMX frames feature a titanium construction. According to Dan's Comp, the top tube of the BMX frame ranges in length from 15 to 22 inches.
BMX Tires
The tires featured on recreational bikes generally have a diameter of 26 inches. The diameter of the BMX tire measures 20 inches. The tread pattern of the BMX tire varies, depending on the specific riding discipline as well as the type of terrain. Tires used for ramp riding feature a narrow body and smooth tread pattern. According to professional BMX rider Brian Kachinsky, street tires have medium-size knobs that protrude from the rubber body.
BMX Pedals
As opposed to the narrow pedals of the recreational bike, BMX bikes feature wide pedals. The wide platform of the BMX pedal prevents your shoes from sliding off during high-impact tricks. According to the Transworld BMX Pedal Buyer's Guide, top-rated BMX pedals are constructed of recycled plastics and composite materials. More durable models of the BMX pedal feature an aluminum or magnesium design. To decrease the overall weight, BMX pedals have a hollow body.
Brakes
Entry-level BMX bikes are equipped with a powerful cantilever brake system for increased stopping power. The brake cable of the BMX bike extends from the handlebars to the rear wheel. To slow the momentum of the BMX bike, hard rubber brake pads squeeze on the metallic rim of the rear tire. The hand-brake lever of the BMX bike is often located on the right side of the handlebars. Many professional-level BMX bikes do not have a brake system.
