Human beings can make the tiny adjustments which allow the bike to continue moving. Higher speeds (if you can call 15mph high speed) are easier to ride at, thanks to our old friend Mr. Newton. An object at rest, tends to stay at rest, and vice-versa. Additionally, since most bikes have a clutch-like system in the pedal assembly, meaning the pedals are not forced to rotate 100% of the time, we can use them as another stationary balance point. This, combined with the fairly obvious nature of the front wheel controlling direction of the bike, and a human being can easily control the direction and thus stability, since the handle bars of a bike are the main source or directional control. The faster you go, the fewer reactions are needed to maintain the desired path, in the same way a car needs less steering effort at 60mph, than at 6mph. Inputs can be smoothed, and made to be more minor, increasing stability. Whereas some spandex wearing d-bag has to use every ounce of energy to balance a bike stationary. This level of effort can be described as an exponential equation, with the effort required to actually attract a mate after being seen trying to balance a stationary bike being the limit of the vertical slope.
This reminds of discussions on turbo lag and shock dynos. Lots of "data", that means 10 different things to 10 different people. Even top medical doctors can be given the same list of symptoms and test results twice, and disagree with themselves. Not all data is valuable, and I think that we forget that far too often.
And LOL gyroscopes. Who the **** thought that made sense?
Yes, all out. In retrospect, I'm a dumbass for spending this much time on this behemoth edifice. But it's fun and will be very useful as a storage and work space. It's 16x12 with 8 foot walls and a lot of loft storage headroom. Total cost was PROBABLY under 4k including ladder, miter saw, and various other tools that aren't actually part of it. Plus assloads of my labor and some braineack labor.
A friend told me to give it a name. I asked if he meant like a description or more like a man's name like "Herb" and he said, "no, more stately like Versailles".
