BMX bike sizes differ so they can cater to different riders. This is welcome, but it can also be confusing if you are a first time buyer. They are generally smaller than touring bikes, but there are differences in their specs.
Their generally small size is necessary for maneuverability reasons. There are many wheel and frame sizes to choose from. The most common measuring criteria is the top tube length. This is the bar that goes from the seat to the handlebars.
The figure is usually from 15 to 21 inches. A longer wheelbase equals a longer tube. This makes a huge difference. A short wheelbase makes spinning maneuvers easier to do. But they are less stable at high speeds. A longer wheelbase has the opposite effect.
Apart from the BMX bike sizes, select the wheel size carefully. The wheel dimensions depend on what kind of ride you are into. The most common wheelbase is 20 inches. This is also used in some racing kinds. Class and cruiser require 24 to 26 inch wheels.
Try different types until you find one that is comfortable. Some BMX bicycles have adjustable seats, but others don’t. Street riders usually have the seat set low. This is necessary to give you space for tricks and stunts. But usually you can lift the seat. It helps in pinching with the knees. This can be a handy feature when attempting complex tricks. Pinching can also make rides more comfortable.
Bike Length and Seat Height
These two elements affect the way the bike feels. Some tall riders like short bikes, but not all. Height is important, but you also have to think of comfort. The majority of shops let you try bikes before buying. This ascertains that it will fit. If the shop allows you to take the bike out for a test drive, do it.
You cannot do this when buying online. In this case, you need to check the product description thoroughly. Examine the return policy in case the bike has to be returned. You also need to check the policies in any bike store.
BMX bike sizes are important, but you also have to think about other things. These include the features of the bike. Their prices must also be taken into consideration. Bear in mind that the sizes you see in calculators and charts are guides. But in the end, the choice is up to you.
