Fast BMX for Skateparks and Technical Tricks

If you enjoy quick bunny hops, manuals, and technical tricks, the PRK MD immediately feels more responsive than longer street-oriented BMX setups.

The short 12.6" rear end makes manuals easier to lift, helps bunny hops come up faster, and gives you smoother control during rotations and technical tricks in the air.

On quarters, spines, and box jumps, the bike reacts instantly and requires less effort to change direction or adjust positioning mid-trick.

This is not a heavy street BMX designed for massive drops or rail abuse. The PRK MD feels much more at home in the skatepark and during technical park lines.

Two Frame Sizes Available

The FitBikeCo. PRK is available in two sizes, making it easier to match the bike to your height and riding style.

• XS – 20" TT frame
• MD – 20.5" TT frame

The MD version offers more stability at higher speed and works best for riders around 160–175 cm tall.

Geometry Built for Fast Response

The short rear end helps you lift the bike easier for manuals and rotate faster during barspins and aerial tricks.

If you previously rode a longer BMX, you will immediately notice the quicker bike response and more reactive front end.

The 25 mm offset fork makes the front end react extremely fast during bunny hops, quick steering corrections, and technical tricks.

Gyro Setup for Barspins and Rotations

The factory-installed gyro allows the handlebars to rotate freely without tangling brake cables. If you are learning barspins or tailwhips, this setup quickly becomes a major advantage.

During faster rotations, the front end feels extremely responsive and easier to control mid-trick.

The updated U-Brake offers increased tyre clearance and smoother spring tension, improving brake feel and control during skatepark riding.

Stable Performance and Smooth Riding Feel

The Cro-Mo front triangle helps the bike handle repeated impacts and daily riding stress more effectively.

The Tubular Cro-Mo cranks improve drivetrain stiffness, while the sealed Mid BB keeps the bottom bracket running smoother during harder landings.

The overall setup is designed more for quick response, technical tricks, and smooth park riding rather than a heavy street-focused feel.

Safety Matters

When learning tricks, it is always recommended to ride with a helmet and proper protective gear. Even experienced riders regularly use protection during skatepark sessions.
