Your First BMX with a Gyro

The SIBMX Düvel 18" is designed for younger riders who have outgrown the smallest BMX bikes but are not yet ready for a full-size 20" model. Its compact geometry makes the bike easier to control while learning the basics of BMX riding.

The Low Park frame geometry delivers quick handling and predictable control, helping riders practise bunny hops, manuals and their first tricks with greater confidence.

The Odyssey G3 Gyro allows the handlebar to rotate 360° without twisting the brake cables, making it easier to learn bar spins and other tricks that involve full handlebar rotation.

Built for Everyday BMX Riding

The durable Hi-Ten 1020 steel frame and matching fork provide the strength needed for regular BMX sessions. Combined with a cassette rear hub and reliable components, the Düvel is ready for everyday riding.

Sunday Current tyres offer dependable grip on concrete, asphalt and pump tracks, while the Odyssey Springfield U-Brake provides consistent braking performance whenever needed.

What Size Should You Choose?

The SIBMX Düvel features an 18.5" frame and is recommended for riders approximately 135–149 cm tall. It is the ideal choice for younger BMX riders progressing towards a full-size 20" bike.

You can find the complete frame geometry in the geometry diagram below the technical specification.
