Back in 2009, the Postbuses in Graubünden took on a pioneering role and fitted rear racks for up to five bicycles on all buses. While the system was later adapted throughout Switzerland, the people of Graubünden are now going one step further again to meet the ever-increasing demand for bike transport. After several years of planning, they have developed a system that can transport 15 bikes in a very small space. Five bikes hang vertically at the front of the trailer, five more are stored on the lower level and five more on the upper level. The rider can lower the levels to ground level - the bikes can then be rolled into the carrier and no longer need to be lifted. Transporting heavy e-bikes or downhill bikes is no longer a problem.

The trailer presented is still a prototype and will be used selectively this summer on the routes to Flims, Lenzerheide and over the Ofen Pass. After detailed modifications have been implemented, it will finally go into production and will be used as standard in the future.
