KHE COSMIC AL 20"
The KHE Cosmic AL 20 inch BMX is a very sturdy and stylish BMX bike, ideal for riders starting out. The lightweight aluminium frame with 14mm dropouts ensures stability and agility at a weight of only 23.4 lbs.
Thanks to our patented KHE Affix Rotor System, 360-degree handlebar spins are possible – perfect for all types of tricks. The 680 mm wide and 8-inch high handlebar offers optimal control, while the forged 3-piece aluminium crank and 32-tooth chainring ensure efficient power transmission. The EURO BB sealed industrial bottom bracket is threaded into the frame, so it cannot develop play like a US BB. The 20-inch double wall rims and wide KHE ACME 2.40-inch tyres guarantee high stability and excellent grip.
Another highlight are the front and rear V-brakes, which allow precise and powerful braking. The colour combination of royal blue frame and fork, shiny chrome brakes, stem, seat clamp and brake levers matches perfectly with the black tyres, handlebar and grips – making this bike a real eye-catcher.
