Now this looks really fun…if not a bit dangerous. They’re images of hotel guests from the Ormond Hotel in Ormond Beach, Florida taken in 1903 (the images were found here). Unfortunately, the hotel–which was on the list of the US National Register of Historic Places was torn down to make room for beachfront condominiums. I love the image on the lower left (click it for a larger view), both of the men have their feet off their pedals and are being pushed by the wind…what could be more fun and freeing.

These trikes with sails can get very fast, I heard! Must be real fun to ride.But a sail on a bike? Have ever tried wind surfing? Really hard to ballance!I would only try this on a bike with a mechanism which allows me to get rid of the sail quick, when I want to. 😉
