Frequently Asked Questions About BMX Cranks

Any length of cranks will work on all BMX bikes but there are a few things to consider, if you are purchasing a replacement crank for a child's BMX its best to measure what you are replacing and match accordingly, 10mm either way is acceptable. If it’s for a full size BMX, the length will be personal preference of the rider, the standard length of cranks is 170-175mm which are great for all types of riding. Some street riders, especially those running 2 pegs at the back sometimes prefer shorter cranks for better heel clearance between their heel and peg. Our handy buyers guide is here to help you find the right cranks.

Longer BMX cranks do not necessarily make you faster. The length of the cranks affects the leverage you have over the bike, but it doesn't necessarily translate to speed.

To make your BMX crank faster you may look to optimize your gear ratio, the standard gearing for full size Freestyle BMX bikes is 25t - 9t. However, there are some other popular combinations.

When choosing a crank arm length for BMX racing, rider height is an important factor to consider. The size of your cranks can have a big impact on your bike's overall performance and handling, longer cranks can provide more leverage and power, but they can also be more difficult to pedal quickly. Shorter cranks, on the other hand, can allow for a quicker pedal stroke but may sacrifice power and stability.
