ari cycles is a custom workshop, which manufactures bicycle frames of the highest quality and craftsmanship. Behind the welding mask is frame builder Ari Rosenzweig, who designs, mills and welds every single frame by hand. Every detail regarding geometry, size, use, weight, dropouts, braze-on, aesthetics and finish is considered with great care. With a large selection of tubing, dropouts and braze-ons each frame is combined into a one-of-a-kind, true custom bicycle. The frames are designed and manufactured with attention to the smallest details, using a combination of traditional craft techniques and cutting edge technology tooling. The frames are made with a no compromise attitude and a lot of passion. The bicycle is supposed to be an extension of the body and mind, and the frame is the heart of the bicycle......
