BMX Hubs

Understanding BMX Front and Rear Hubs

At the centre of the front and rear wheels on a BMX bike, you’ll find the BMX hubs. They join the wheel rims to the BMX frame via axles and spokes. The front hub's function is to let the front wheel rotate smoothly. However, a BMX rear hub is a bit more complex with additional components like a driver along with pawls and springs to enable the rear wheel's movement when pedalling.

Freecoaster vs. Cassette Hubs: Understanding the Differences

If you are selecting a new rear hub for your BMX, you must choose between a freecoaster and cassette hub. Neither system is superior, but considering your riding style could guide you to the more suitable option.

BMX Freecoaster Hub

The notable feature of freecoaster hubs is their ability to let you ride backward without pedalling—essential for practising fakie tricks and backward riding. However, they come with some “slack,” which means there’s a slight delay in engagement when you begin to pedal.

BMX Cassette Hub

Cassette hubs offer immediate engagement when pedalling, which aids in quicker acceleration and assists beginners in learning basic tricks like bunny hops and manuals. The drawback is the necessity to pedal while rolling backward, with your feet needing to be level before reversing direction.

Choosing Right Hand Drive vs. Left Hand Drive Hubs

Rear hub models are available in right hand drive, left hand drive, or both. This choice is mainly personal, but riders often opt for left hand drive if they primarily grind on the right side, and right hand drive if they grind mostly on the left. Grinds utilise pegs fastened to the hub axles, which are not typically included with most BMX bikes.
