I have been commuting with the single Vision R40 since early January of this year. And I have never been happier cycling.
However, I just purchased and R82 Vision Tandem recumbent and feel like I am riding a pogo stick. It appears to be oscillating with undulations in the road. In my estimation there is a damping problem that doesnt permit the bike to absorb the vibrations it receives from the road. As a result the bike feels unstable as it vibrates up and down with every divet we encounter in the road. ATP says they dont have any idea why the one I have just purchased rides any differently than an earlier model that I rode last year. Perhaps someone in this chat has a better answer or suggestion.
