Getting Started in BMX Racing
Author: admin
BMX racing is a fun sport for young people. For kids, the basic bike should have 20-inch wheels. Riders under age six can use whatever type of bike they have, even if it’s not a true BMX freestyle bike. These little folks might still be riding bikes with wheels as small as 12-inches. Some tracks even have races for Big Wheel bikes.
A cruiser or mountain bike with 24-inch or 26-inch wheels might be okay, too, but check ahead of time with your local track for advice. Many tracks will let you race a mountain bike in the “Cruiser” class.
Whatever bike you use should be equipped this way. Remove all reflectors. Take off the kickstand and chainguard to prevent injury in a wreck.
The bike should have pads on the top tube, stem and crossbar. Most BMX freestyle bikes already have these pads. If your bike doesn’t have them, adding this safety feature will cost about $5.
The bike should have at least one working brake. A coaster brake is fine if that’s all the bike has. The bike should be in safe working order.

Bicycle Rims And Wheels, Your Bike Cant Go Anywhere Without Them

The first bicycle wheels were from a horse drawn cart, made of wood with a metal band round the bicycle rim, very hard and very uncomfortable to ride. Then a man called Dunlop (Scottish) invented the pneumatic tire, this along with Macadam (another Scot) inventing the tar road surface made cycling a lot more comfortable.
The bicycle rim, like the bicycle frame hasn’t changed much in design, its still round and always will be. From the first wooden rims the next were made of steel, then alloy and now if you can afford it, carbon. Of all bicycle parts the bicycle rim can make a big difference to how your bike handles. First the weight of your rim affects your sprinting and climbing as the weight will low you down, for a long, flat effort the weight isn’t so important as when you get the wheels rolling the weight can help to keep them going. The shape of the rim can be important also, a flat rim is best for climbing as aerodynamics are not so important on a hill, a deep section, aero, rim will help you cut through the air, but in a cross wind could cause you handling problems.
