Description Creating innovative, stylish and at the same time sustainable forms of mobility for the city - with this in mind, Valentin Vodev, industrial designer and VELLO Founder, developed the VELLO SUB, the family van among the sustainable means of transport. VELLO positions itself as a driving force behind the megatrend between connectivity and micromobility. The SUB is available in two models, one in chromoly frame and stepless gears from Enviolo and the ultralight titanium frame model, which weighs only 24 kg in the singlespeed version, making it the lightest cargo bike in the world.
