BMX Rims

Understanding BMX Rims

BMX wheel rims are metallic structures that support the tyres, linking them to the hub via spokes. These rims may be crafted from aluminium, steel, or even superior materials like carbon fibre.

Which Size BMX Rims Should I Choose?

The standard rim diameter for both freestyle and racing BMXs is 20 inches, a size found in typical and pro BMX models, suitable for adults and taller children. Smaller sizes like 18, 16, and 14 inches cater to younger or shorter riders. For those into freestyle riding, refer to our BMX Freestyle Size Chart to find our recommendations based on age and height.

The width of BMX rims generally ranges between 30-36 mm. While 32 mm is the typical choice, some prefer narrower rims for lighter weight or wider ones for added stability.

The number of spokes accommodated by BMX rims impacts both wheel weight and strength. A 36-spoke wheel is standard and but suitable for freestyle. More spokes enhance strength, so seasoned or heavier riders might opt for rims supporting more spokes, with 48 being the next popular number. In contrast, race BMX cycles usually have fewer spokes in their rims to reduce weight and boost speed.

Single vs Double-Walled BMX Rim Options

When selecting rims, deciding between single or double-walled varieties is crucial. Double-walled rims are recognised for their robustness, making them ideal for freestyle use, thanks to their excellent strength-to-weight ratio.

While single-walled rims are less robust than double-walled ones, they are typically more cost-effective. This weight reduction appeals to some racers as a preferred option.
