Spokeless bicycle by a student to travel to Yale University, one semester
Remember that the last Star Trek movie, where James T. Kirk went to Starfleet Academy sign on a motorcycle? Honestly, I thought there were no motorcycles in the twenty-third century, but the film has done all that could make it too futuristic. In fact, if you look hard enough, you'll see that the wheels have no spokes!
How is this possible? Probably with the same technology that drives workflow makes dilithium crystals, probably. However, where some engineering class at Yale seeks to use technology to deliver real spokeless wheels on the bike.
As you can see, the string is not in a rate that is fixed in the middle of the back wheel, but rather on a wheel that can rotate the rear wheel. In case you're wondering why the two wheels are not spokeless, then you should know that the group was simply time. I mean, she had only one semester, and if I know how the students work, they probably spent ten weeks of 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 never tried a cycle of ever spokeless build. This raises the question, why build a cycle spokeless? Rays are dangerous? They slow down a motorcycle?
Incidentally, this is not too far spokeless cycling affected. The frame is made every electric motor, and perhaps even “a kind of cart storage gyro-balanced.
