cool video! I don't ride bikes, but I plan on in a few years, so I gotta ask you this how do you straighten yourself out when you lean too much to one side of the bike during turns? does pressing one of the brakes make a difference?
increasing speed will level the bike but also doing counter steering so literally if you're leaning left you push handle bars to the left, that is why you can't lock your handle bars and always have some room to push. This is what you do while doing figure 8
