The KHE Black Jack is one of our new BMX 20" aluminium bikes! It is extremely light, making it easier to ride and the perfect bike for young riders.
At only 22.49lbs / 10.2kg, you won't find a lighter freestyle BMX in this price range anywhere else in the world!
As the name suggests, this aluminium edition has a high-quality aluminium frame. But because it is reinforced in the right places, the BMX can withstand any jump! In addition to its patented AFFIX rotor, the KHE Black Jack also has an adjustable saddle, which allows the rider to optimally adjust the seat angle. The bike has an aluminium U-brake front & rear. The bike has a great spec, like the Affix rotor, top loader stem or the BIG400 (35mm wide) KHE rims!We have managed to reduce the weight to only 22.49lbs / 10.2kg, which means great handling and even more fun.
