Freestyle Bike Sizes
For all BMX bikes with standard 20” wheels we measure the size of the bike by the length of the frame. We use the length of the top tube as the measure of the size and we have grouped our bikes together into Small, Medium, Large and XL sizes.
Standard BMX bikes use a 20” diameter wheel. Kids BMX bikes use a smaller wheel size to allow for a smaller bike while maintaining that classic BMX bike proportions. The same goes for larger wheeled bikes which are great for just cruising around.
When it comes to race bikes, all the wheels are 20” in diameter but the smaller bikes use a thinner tyre for less drag and weight savings. There is also a 24” diameter wheel called a cruiser.
