Kurt designed and built this back-to-back tandem recumbent, nicknamed the Beast. The design allows either rider to idle or pedal, unlike other tandem designs which require riders to pedal in sync.
After the Beast was idle awaiting repairs for several months, the Kurt and Turner were able to get a few more rides in before Turner graduates high school and moves away to a summer job and college.
The Beast is quite spry itself, despite it's novel look and comfortable seats. I've seen these guys easily exceed 20 mph on flat ground. The open middle has a "floor" and could be packed for cargo hauling or touring.
Now that the Beast is repaired, I hope we continue to see it out on the road!
