  7. I'm going to rate this experiment and video presentation at 3/10 legitimacy. It would have been more interesting (or less interesting, depending on perspective) if you tried this with people who knew how to ride a bike. Your assessment of steering not working when you're sitting still was also incorrect. Ask anyone who's sat still, feet on pedals, waiting to drag race cars at a stoplight...that's not even getting into people who do trick riding. You're assessment of a bike not being able to be ridden with locked steering is also incorrect. You can't steer to adjust lean to correct for weight transfer, but you can adjust your own weight above the bike. Any kid who ever crashed and had a brake cable bind up preventing steering could tell you that. Also, gyroscopic force will keep the bike up, but only at higher speed. Say, if you locked the bars while going down hill. With the caveat that rider input or movement will actually work against the natural gyroscopic stabilization. Obviously, that's an unsafe experiment (especially with your volunteers that can't ride a bike anyway). I used to race BMX, wasn't even very good or successful with it, but can still see that if you had chosen different riders (ones who were more accustomed to weight shift) your experiment would have had different outcomes. As a final note, the test bike was too tall for every rider shown and that on its own would make riding difficult even with normal steering. I'd suspect that you also didn't have a beneficial gearing, instead choosing a gearing that would encourage more force to pedal and thus more weight shift that would need to be countered (either by steering or adjusting the position of the rider atop the bike).
