BMX Rims

Introduction to BMX Rims

BMX rims are the metal structures of the wheel that secure the tyres. They are linked to the hub with spokes and crafted from materials like aluminium, steel, or higher-end options such as carbon fibre.

Choosing the Right Size BMX Rims

The typical rim size for both freestyle and racing BMX is 20 inches—the standard diameter for regular and pro BMX models, suitable for adults and taller youngsters. Smaller sizes like 18, 16, and 14 inches cater to shorter riders. For freestyle enthusiasts, refer to our BMX Freestyle Size Chart to find the wheel/rim size we recommend according to age and height.

While BMX rim width can differ, it typically ranges from 30-36 mm. The prevalent size is 32 mm, although some riders prefer narrower rims for reduced weight or wider ones for enhanced stability.

The quantity of spokes a BMX rim can support influences the wheel's weight and strength. Generally, 36 spokes are common and ideal for freestyle. More spokes mean greater strength, so advanced or heavier riders might opt for rims that accommodate more, with 48 spokes being another popular choice. Race BMX bikes often feature fewer spokes than freestyle rims to decrease weight and boost speed.

Single-Walled vs Double-Walled BMX Rims

One significant decision when purchasing rims is choosing between single or double-walled. Double-walled rims are often seen as more robust, ideal for freestyle riding, and offer an excellent strength-to-weight balance.

Single-walled rims are less robust than their double-walled counterparts and thus are generally more cost-effective. However, their lighter weight makes them a preferred choice for some racers.
