It is not exactly clear what Everything2 is about, but it is not Wikipedia, and so does not appear to have any requirement for assertions to be supported by reliable sources or consensus among contributors . The article about gyroscopes, is a good example of what that yields:
In the bicycle’s case, the gyroscope effect of the wheels will help keep the bicycle upright and resist falling over, because falling over would be a change in the rotational plane of the wheels. It also helps the bicycle maintain a course roughly straight ahead, because turning would also be a change in the rotational plane of the wheels, which allows a confident rider to take his hands off the handlebars.
Here we have more perpetuation of the misconception that spinning wheels somehow resist falling over and even turning. In reality, large external moments, from gravity and the rider, are applied that easily alter the angular momentum vector of each wheel.
I would try to contact Everything2 about this problem, but they required anyone to Log in or register to write something here or to contact authors, and I need another login id and password like I need a hole in my head.
