    The walking machine wasn't really a failed invention. A version of that mechanism has been used on large equipment for many years.
    The bike with the sails would have been a very challenging thing to ride. Wow

    The first one is more 'art bike' than invention; I seem to remember seeing it somewhere before. The second is very much like the modern elliptigo https://www.elliptigo.com/, the tiny bikes are still sold today https://www.unicycle.com/udc-mini-bike/ (plus dozens of DIY builds scattered among the internets. )

    Here's a lot of bike sail designs
