This Bicycle is a concept for a Massive Messenger Bike, the prototype is made mixing commercial Parts and 3d printed components, it has a 36" rear wheel ( covered with neoprene) with an Internal Geared Hub, inspiration comes from Pursuit Bikes, but although it looks like huge and extreme, the ergonomics it's not so far from a standard road bike, the smart frame makes possible to have a short bike for normal people ( from 1.75 m -  5.74 ft ). the Frame is super symmetrical, this means that left and right side are mirrored, and the top and bottom  too. It has been designed to be easy to build in series, using only few components .
