KHE 2025 BMX Series
With over 35 years of experience, KHEbikes combines innovation, advanced engineering and outstanding riding dynamics. The new 2025 models offer optimised geometry, thoughtful details and high-quality components – directly from the manufacturer for top performance on any terrain.
KHE COSMIC AL 20"
The KHE Cosmic AL 20 inch BMX is a very stable and stylish BMX bike, ideal for riders starting out with BMX. The lightweight aluminium frame with 14 mm dropouts ensures both stability and agility at a total weight of just 10.6 kg (23.4 lbs).
With our patented KHE Affix rotor system, 360° barspins are possible – perfect for all kinds of tricks. The 680 mm wide and 8 inch high handlebar ensures optimal control, while the forged 3-piece aluminium crank and 32-tooth chainring deliver efficient power transfer. The sealed EURO BB bottom bracket is threaded into the frame and therefore cannot develop side play like a US BB system. The 20-inch double-wall rims and the wide KHE ACME 2.40 inch tyres provide excellent grip and high stability.
Another highlight is the front and rear V-brakes, which enable precise and powerful braking.
Recommended rider height: 135–170 cm (4'5"–5'7")
Maximum rider weight: 75 kg (165 lbs)
Ideal for: Park, pump track, street, race, flatland
