  • Number5unexplained is the solution for urban mobility. She is a long tail cargo bike, designed to carry people, pets, and stuff.
  • She is light and agile, fits in a normal regular bicycle parking space, and can be taken on train and metro (in some cities also on buses). Number5unexplained sets a new standard in bicycle design, production and distribution.
  • The monocoque frame of Number5unexplained is designed and produced using digital technologies.
  • The box bike’s frame is laser-cut and CNC-bent from a sheet of lightweight aluminum. This gives her a distinctive look and allows us to produce her frame in small quantities and in your area.
  • We develop Number5unexplained in a continuous process, based on the feedback we receive from you, during workshops and in using the bike.
