Sail Bike in action by Pierre-Yves Gires * Dunkerque (France)

. Just for fun, here inclosed, a video of my own tack of sailing in France with bicycle. I call it "WindBike" (or "Vélo à Voile", in French). My speed records (windspeed +/- 30 knots) :
42,88 mph, on the sand
52,20 mph, on the asphalt
French Inventor : M. Patrick Carn (a close friend)
Best Regards,
