Sometimes Manfred would like to rest on a couch and lay his legs high. Therefore, Santa Claus had brought a parcel from the Dutch carbon ligfietsen producer M5. In the parcel was a frame rack, with which Manfred built a couch :-) In the meantime Manfred pedaled some thousands kilometres recumbently. His experiences in riding the couch you find here: https://manfred-tinebor.fotki.com/journals/couch-surfing/ To get a little impression of riding the couch speedy, please watch the video recorded on a country road in Lower Saxony between Polle and Bad Pyrmont: https://manfred-tinebor.fotki.com/journals/manfreds-videos/entry/wqtfrbtwwtqqq/
