I have been doing some experiments to carry around the Mini125RD as a backpack. It seems to work better then expected. After some trials, it turned out that the best solution is just a simple 50mm strapping, with some buckles to enable adjusting. I just knot it to the handlebar. I have experiemented with some foam additions for improved comfort, but they are not really needed. You can just adjust the position of the bike with the buckles and then it works fine. So far I have used it only for a 10 mile trip to bring a bike to a group of friends. I will test it a little better in the future. The strapping and buckles weighs 150g and can be knot on in about 1 minute. It is possible to ride the Mini125RD with the strapping on without trouble.
