KHE COSMIC AL 20"
The KHE Cosmic AL 20-inch BMX is a very stable and stylish BMX bike, ideal for riders starting their BMX journey. The lightweight aluminum frame with 14mm dropouts ensures stability and agility at a weight of just 10.6 kg (23.4 lbs).
With our patented KHE Affix Rotor System, 360° handlebar spins are possible, perfect for all kinds of tricks. The 680 mm wide and 8-inch high handlebar provides optimal control, while the forged 3-piece aluminum crank and 32-tooth chainring ensure efficient power transmission. The EURO BB sealed bottom bracket is securely screwed into the frame, preventing lateral play as seen in US BB bottom brackets. The 20-inch double rims and wide KHE ACME 2.40-inch tires guarantee high stability and excellent grip.
Another highlight is the front and rear V-brakes, which provide precise and powerful braking. The red grips, red chain, and red seat clamp contrast perfectly with the matte black frame, fork, and handlebars.
Recommended rider height: 4'5" - 5'7" (135-170 cm)
