Our patent pending trapezoidal design for 2-wheeled vehicles allows the ADV1 to essentially lock in place when you're at speed and leaning to steer. Once you're over about 20 mph, instead of a 2-wheeled motorcycle pulling a 1-wheeled trailer, the two machines become one 3-wheeled vehicle that is stunningly stable. However, when you're steering with your handlebars (taking a corner or maneuvering in a parking lot), the hinge swings freely and allows you to maneuver and control your bike as you would without a trailer.
The final hinge will look very different from the proof of concept you see to the left, and it will have a larger range of motion. But, we had to prove it would work, and Luke (our engineer) figured out this very fast, easy way to do it!
