Crank LengthUpdated a month ago

Crank Length is super important when it comes to how your bike feels and rides. 

Freestyle BMX Bikes:

Just like Riders, cranks come in all different shapes and sizes, the average size of Freestyle BMX crank is 170mm -175mm, with most complete bikes coming with this size as standard. Shorter cranks 160mm-165mm offer a shorter rotational distance and therefore enable the rider to spin faster, (similar to spinning around on an office chair and pulling your arms in). Shorter cranks also make it easier to hop higher since your feet are closer together on the bike. (try jumping with your feet spread wide apart on the ground, then try with them close together) Shorter cranks are typically favoured by street and park riders, whereas longer cranks are favoured by dirt and trail riders as they offer a longer stroke and more stability.
