Hi, I saw a video online of a self balancing 2 wheeled car. Basically a motorcycle with a body though has a steering wheel rather than handle bars. It uses two gyroscopes spinning in opposite directions to keep it's balance and was wondering if a similar thing could be adapted for regular motorcycles out of curiosity. I have researched on how gyroscopes work but I was wondering does the mass of the spinning disc/wheel effect how much force is being created? So assuming it is, would you need a heavy spinning mass to keep a motorcycle upright? Also a motorcycle or a even just a wheel can keep it's self upright if spinning fast enough same with a coin if you roll it then it remains upright. I then thought would the same effect happen if the wheel it's self was stationary but a inner cylindrical mass was spinning inside of it would it keep the wheel upright? If that's the case then would making a motorcycle wheel with a spinning inner mass in the wheel keep the bike upright?
