Here are some more pictures from the patent request.

In a design like this, with the swingarm axle through the countershaft, a normal clutch on the primary gearbox shaft would be in the way. Therefore the clutch is located at the very end of the crack. Where it turns faster than normally and has to put up with less torque than in a conventional engine. So it can be smaller as well. As you can see the countershaft is hollow. Item 10 is the swingarm axle, which goes straight through the countershaft. Removal of the swingarm looks like just as much work as the front wheel.

Item 5 is the frame, 11 the swingarm and 12 the front sprocket.
