|Just how much bike do you
That depends on your weight, and what you are going to do with/to the bike.
We distinguish between six levels of quality for BMX bikes based on the frame materials and components:
There are no official weight limits. Even the strongest parts can be destroyed. Warranties do not cover anything that is bent. It is more cost effective to spend more for a complete bike that has at least everything you need, than to replace with stronger parts later.
There are two possible mind sets in
play when doing stunts:
* There are many versions of steel.
Those found in bicycles are typically the following:
|What size bike do you
It's not just the wheel size, it's the top tube length (the distance from the seat to the handlebars). While personal preference can override this chart, here are the normal sizes for BMX bikes with 20" wheels.
18.5" for riders 4' 3" - 4' 6"
19.5" for riders 4' 5" - 4' 8"
20.0" for riders 4' 9" - 4' 11"
20.3" for riders 5' 0" - 5' 3"
20.5" for riders 5' 3" - 5' 9"
20.8" for riders 5' 8" - 5' 10"
21.0" for riders 5' 9" and taller
This sizing is to facilitate proper weight distribution and handling. It is reasonable to assume that some younger riders will grow into a larger bike by the time they are adventurous enough to be doing any real stunts. However, if the rider is already doing stunts, they will need a bike that fits right now.
With adult bikes that come in multiple sizes of seat tubes (and top tubes), the top tube measurement is called "effective top tube length" and is measured as if the top tube were parallel to the ground. With BMX bikes, where all tube slant by approximately the same amount, the measurement is simplified and is the length of the actual tube, measured from the center of the head tube to the center of the seat tube.
|Different Types of BMX
By far, the most popular style of BMX bikes today are «freestyle» bikes. These are designed to handle well when doing stunts. They are built with extra strength compared to race bikes.
The original BMX bikes were designed for closed loop, banked turn, dirt track racing where there are typically eight racers on the track per moto (heat). «Race» bikes are built for speed and are much lighter than freestyle bikes.
A style of BMX that was popular in the 1980s is known as «flat land». The stunts done with these bikes look like gymnastics with the bicycle as the apparatus. No jumps, track, or obstacles are required, just a flat surface.
