    possible tandem frame

    Any one seen the W.Y.M.S. Any one seen the W.Y.M.S. (With Your Main Squeeze) tandem by Bill Patterson? Here's a link to a tiny video. It can be controlled...by two middle-aged married people - with no hands! Well, the people have hands, but the captain doesn't steer with them...

    Stringbike drivetrain - Adapatability to Cruzbike frame?
