Just curious about this one. Like all of us, I'm sure, when stopping at red lights, etc. I'll often try and see how long I can stay balanced before having to put my feet down. As I focused more on this endeavor, I found myself getting a little better at increasing my times.....but still only reaching 3-4 seconds under ideal conditions ( no wind or other extraneous influences ). The type of tire has a lot to do with it. Big, fat tires like one would find on a cruiser would be a big help. Our more performance oriented tires with somewhat of a " point " on them don't help matters.
In any event, I reached a personal record today of approximately 10 seconds. I say approximately because I was using the old one-thousand-one, one-thousand-two timing system....could hardly look at my watch. I wonder if any cagers around me found my body maneuvering interesting as I was trying to hang on as long as I could. I'm claiming a world record.
