A BMX with a Gyro for Learning Tricks

The SIBMX Düvel 20" is built for new BMX riders who want a bike that feels stable from the very first session. Its Low Park geometry delivers responsive handling, making it easier to learn the fundamentals and gain confidence.

An Odyssey G3 Gyro allows the handlebars to rotate a full 360° without twisting the brake cables. This makes practising barspins and other rotational tricks much smoother while keeping reliable braking performance.

Whether you're riding at the skatepark or on a pump track, the Düvel provides a solid platform for building your BMX skills.

Built for Everyday BMX Sessions

The Hi-Ten 1020 steel frame is paired with strong 3-piece Cr-Mo cranks for improved durability and efficient power transfer. These components are designed to handle regular riding and repeated practice.

A cassette rear hub with a 9T driver provides quick drivetrain engagement, while the Odyssey Springfield U-Brake delivers dependable stopping power. Wide Sunday Current 2.4" tyres offer excellent grip on concrete, asphalt and pump tracks.

Choosing the Right Size

The SIBMX Düvel features a 20" frame and is recommended for riders approximately 145–160 cm tall. It is an excellent choice for riders moving onto a full-size BMX bike.

The complete frame geometry can be found in the geometry diagram below the technical specification.

Ride Protected

Learning BMX involves crashes and hard landings. Wearing a properly fitted helmet together with quality protective gear helps reduce the risk of injury and lets you focus on progressing with confidence.
