The idea is cool, but there are huge disadvantages, a weak front fork, weak brakes, the rear wing needs to be done normally, put a normal rod on the rear pendulum (like how tracks are connected on a caterpillar), add a second brake disc on the front wheel. Yes, and on the rubber, make a trim like slicks, it will be easier to enter the turn. Safety arcs need to be installed, without them it is very dangerous to ride such a thing. And in this state it is very dangerous to travel on public roads. Impressive video. All done without machine tools making all those divisions using nothing but a scale and felt writer. Very impressive! As always a good idea! Two small notes, the front fork will be modified with some articulated arm to help the shock absorbers, the rear one also with a greater inclination of the shock absorbers. For the rest great job!
