The wheel has been round with an axle at its centre ever since it was invented. The formula has remained this way for millennia (apart from the best forgotten Austin Allegro of course), because, well… any other method would be stupid.

Such logic doesn’t apply to concept car designers though, who regularly seem to devise a way of complicating the simplest and most reliable invention in the history of mankind.

So it is with today’s two creations, each of which applies some concept car designer madness to their aesthetic. First up (above) is BobDeQuatre‘s ‘Harley Davidson E-Wanderer’, an electric motorcycle concept built for a ‘Future Harley Davidson’ contest on the LEGO Ideas platform. Axles have clearly been banned in the future as Bob’s motorcycle does away with them altogether in favour of a set up that looks far cooler. See more of his E-Wanderer concept at the link.

Today’s second bike concept comes from Sheo of Flickr, who has not only removed the axle, but also any semblance of roundness too. We assume the track thingumy that replaces the wheels is actually two separately rotating pieces otherwise this ‘Infinity’ hydrogen fuel cell concept won’t be going anywhere at all. Deceptively large, Sheo’s creation includes some awesome brick-built lettering and a slightly terrifying model/rider to accompany it, and there’s more to see via the link above.
