BMX Rims

Defining BMX Rims

BMX wheel rims are the metal frameworks securing the tyres in place. They link to the hub via spokes and may be crafted from aluminium, steel, or even high-end materials like carbon fibre.

Determining the Right BMX Rim Size

A 20-inch diameter is the standard for both freestyle and race BMX bikes, fitting adults and taller children. Smaller options like 18, 16, and 14 inches cater to younger or smaller riders. Freestyle enthusiasts should refer to our BMX Freestyle Size Chart for size recommendations based on age and height.

Rim widths generally range from 30 to 36 mm, with 32 mm being most common. Some riders opt for narrower rims to cut weight or wider ones for added stability.

The number of spokes impacts wheel weight and strength. A common choice is the 36-spoke wheel suitable for freestyle. More strength is achieved with additional spokes, so advanced or heavier riders might prefer a 48-spoke configuration. Racing BMX bikes frequently feature fewer spokes to minimise weight and boost speed.

Choosing Between Single and Double-Walled BMX Rims

A key choice when purchasing rims is deciding between single and double-walled types. Double-walled rims, being more robust, are ideal for freestyle, offering an excellent balance of strength and weight.

Single-walled rims lack the strength of double-walled ones, thus are typically more budget-friendly. This lightness appeals to some racers.
