Park BMX with a Fast Front End and Short Rear

The FitBikeCo. PRK MD 20.5" delivers a quick and responsive feel from the first push. The short 12.6" rear end makes manuals easier to lift, helps rotations come around faster, and gives you more control during technical tricks.

The 75.3° head angle creates a fast-reacting front end that responds instantly to bar movement. If you enjoy technical skatepark riding, quick quarter transitions, and fast park lines, this setup feels agile and responsive straight away.

Gyro Setup for Barspins and Rotations

The gyro system allows the handlebars to rotate freely without tangling brake cables. This makes barspins, bus drivers, and other rotational tricks feel smoother and more controlled.

The U-Brake provides reliable speed control in the park, while the increased tyre clearance keeps braking performance consistent with wider 2.4" tyres.

Cro-Mo Strength Where the Bike Takes the Biggest Hits

The Cro-Mo front triangle is built to handle harder landings, bigger impacts, and regular skatepark riding better than standard Hi-Ten construction. This becomes especially important once you start pushing tricks harder and riding more frequently.

The 3-piece Tubular Cro-Mo cranks increase drivetrain stiffness and provide a more direct power transfer during bunny hops and transition pumping.

How to Choose the Right BMX Size?

The 20.5" TT frame is best suited for riders around 160–175 cm tall. This size gives a balanced mix of control and bike space without feeling too long in the front end.

If you want to progress faster with manuals, rotations, and technical tricks, choosing the right TT size makes a noticeable difference. A frame that is too long feels harder to pull up, while a frame that is too short may feel unstable at higher speed.

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.
