At CUBE, we make no compromises in the development of our kids' bikes, which is why the lightweight Acid 200 Disc frame is made from the same high-quality 6061 aluminum tube sets as our adult models. It is stable and durable, able to withstand even the highest demands and the wildest maneuvers. Additionally, it features disc brakes on both the front and rear wheels, as well as a replaceable derailleur hanger, so that after a fall, the entire frame doesn't need to be replaced. The quality is clearly in the details!
