I saw your post. My company is x2Cycle that makes the Tandem Rack. It was developed for exactly the type of situation you describe-- riders of uneven ability (works for 2 adults or an adult & child) that want to connect occasionally. You use your regular bike & can go from connected to riding individually in about 5 seconds. Check out our web site at x2Cycle.com. If you try one & it doesn't work how you expected, we have a 60 day money back guarantee. Best of luck whichever way you go.
