BMX expertise for confident riding

BMX is a demanding discipline where every component is put under significant stress. Whether you're into skatepark features, street spots, dirt jumps, or pure speed on a pump track or BMX race track, choosing the right gear is essential for your progress and safety.

1. Freestyle vs. Race: Find your style and geometry

Your choice of parts and complete bike depends directly on how you ride:

BMX Freestyle (Street, Park, Dirt): Prioritize durability with Chromoly steel (4130 Cr-Mo) frames, a top tube (TT) suited to your height, and reinforced components built to handle hard landings.

BMX Race: Focus on light weight and responsiveness with aluminum or carbon frames, aggressive geometry, and precisely selected gearing to launch you out of the gate.

2. Essential criteria for choosing the right BMX gear

  • Frame size (Top Tube): Measured in inches (from 18" for younger riders up to 21" or more for taller riders), this is key to perfect control in the air and on the ground.
  • Gearing and drivetrain: Choose the right chainring and cog to find the ideal balance between acceleration and top speed.
  • Wear parts and safety gear: Choose grippy tires, double-wall rims, sealed bearings, and appropriate protective gear (helmet, elbow pads, knee pads).
