Technic rollin’
I’m usually reluctant to post notes on my own MOCs, and that is why Hippotam occasionally uses the Power of the Poke to convince me to post one 
So it was in the case of my model of one of the world’s weirdest vehicles ever - a diwheel.
Diwheel is basically a type of bike with two wheels parallel to each other, and the actual bike residing inside the wheels, kept in place by its low placed center of gravity. If you’re interested, you will find plenty of informations on diwheels and monowheels here.
As for the model itself, it’s key feature is an advanced drivetrain. I’ve used a subtractor, that is a mechanism able to add or subtract the speeds of two motors and distribute it independently to two wheels. Thanks to that, the diwheel is able to quickly drive straight and still make precise turns, which would be otherwise impossible with the wheels so close to each other.
You can learn more on the functionality of the subtractor, and of the diwheel’s driving characteristics from the video:

Amazing engineering. What set are those wheel treads from?
