Spokeless bike made by Yale students, in one semester

by Mark R

Remember that latest Star Trek movie, where James T. Kirk goes to register for the Starfleet academy on a motorcycle? In all honesty, I thought that there wouldn’t be motorcycles in the twenty-third century, but the film did everything it could to make futuristic. In fact, if you look close enough, you will see that the wheels have no spokes!

How is that possible? Probably with the same dilithium crystal technology that makes warp drives work, probably. However, some Yale mechanical engineering class tried to use real technology to put spokeless wheels on a bicycle.

As you can see, the chain is not attached to a gear that is in the center of the back wheel, but rather to another wheel that can spin the back wheel. Just in case you are wondering why both wheels are not spokeless, then you should know that the group just ran out of time. I mean, they only had one semester, and if I know how students work, they probably spent ten weeks planning it out, and two weeks building the final model.

Of course, I could be wrong. Who am I to judge? It’s not like I’ve ever tried to build a spokeless cycle of any kind. Which begs the question, why build a spokeless cycle? Are spokes dangerous? Do they slow a bike down?

By the way, this isn’t it as far as a spokeless bike is concerned. The design frame is made to possibly do an electric motor, and maybe even “some sort of gyro balanced storage basket”.

This concept by these Yale students isn’t new, there is already a real mototrbike which was made spokeless. This is truly pathetic by such brains of Yale- my grandma could have come up with this idea literally. Don’t believe me, than watch YouTube you idiots at http://www.youtube.com/watch?v=yJPTSaARlvs&feature=player_embedded and tell me if you still think Yale students are smart or slackers!

More like Yale Copycat Kids. All they did was copy someone else idea from YouTube.

Actually, yes, spokes do slow bikes down just a little bit. Hence, why time trial bikes look like this

The hubless wheel was invented by Sbarro in 1989. That year he showed a prototype car the Sbarro Osmos.


In 2009 he introduced another concept:
