When I came across this hilarious and awesome way of transportation I thought "why is no one rollerblading through the woods anymore?". I am pretty sure there are more fantastic but forgotten inventions out there, or new ones like these water bikes.
For my setting I searched for means of transportation especially independent of fuel. Recreational benefits are not excluded. Also, like the example with the mono-blades, they should allow the user to cross remote terrain either on land or by water, or both. Walked out paths exist, but not asphalt roads. In either way, it needs to be a twist on our commonly known transportation methods, or a new one, with the promise to actually work and not just "rollerblades on a horse".
Our landscape is placed inside a space settlement (O'Neill cylinder) with a total area of about 900 km2, serving as a nature conservation area with strict restrictions. There are all kinds of landscapes, ranging from mountains, forests, swamps, lakes, plains, beaches, in a temperate climate. Anything futuristic is allowed, but as said, no fuel, and if you can make use of the setting you get a cookie. Your answer can either be an existing invention or your own. It could function for either children, single people or groups, and it can include existing animals.
So. What other human-powered transportion methods do or could exist, besides the commonly known?
Edit: No, food is (of course) not considered a fuel in this scenario. That would be illogical. While food is, technically speaking, a fuel, "fuel free transportation" implies that one does not have to use energy beside human energy, because the device is to be operated by humans. How could humans operate anything without food. "I want to ride my fuel free bike, so I guess I'm not eating anything today"?!
Edit 2: Anyone who continuous to nitpick on "food is a fuel" is missing the point on purpose and can blame themselves for not getting a cookie.
