Meybo HSX Alloy BMX Race Frame

The Meybo HSX Alloy delivers the same race-proven geometry and aggressive performance as the carbon version, built around a lightweight and durable alloy platform engineered for serious BMX racing. Designed to maximize stiffness, handling precision, and efficient power transfer, the HSX Alloy is built to perform at the highest levels of competition.

Used by elite riders, including members of the Dutch National U23 squad, the HSX platform is engineered to handle the demands of modern BMX racing while maintaining a stable and predictable ride feel through every section of the track.

The frame features Meybo’s fixed chainstay system combined with a 15mm bolt-through rear axle and HSX tensioner system. This design maintains a consistent chainstay length regardless of gearing changes, ensuring the bike delivers the same handling characteristics every ride.

On Pro sizes and larger, the HSX Alloy utilizes a tapered 1.5 head tube for increased front-end stiffness and improved steering precision at high speeds. An oversized bottom bracket platform further enhances power transfer for explosive acceleration out of the gate.

The integrated flat mount disc brake system provides clean aesthetics, reliable braking performance, and simplified maintenance.

Whether racing at the local national level or competing internationally, the 2026 Meybo HSX Alloy is designed to help riders maximize performance every lap.
