What makes a bike stay upright? Many of us can repeat the conventional grade-school wisdom that the gyroscopic effect is the magical stabilizer of the spinning bike wheel—but scientists are finding that the physics of biking are much more complex than this, reports Science News. They are learning this in part by trying to knock over moving bikes.
A bicycle in motion, even riderless, can coast for long distances without falling. The bike-abusing researchers are learning that neither the gyroscopic effect nor another long-accepted explanation, the “trail effect,” entirely explains the bike’s stability. Writes Science News:
So remember, bikers, whether you’re keeping it pure on a fixed-gear or geeking out on a slow-rolling “comfort” bike, many of the same physical forces apply. And as for the oft-maligned weird cousins of the bicycle world, recumbent bike riders? They are no less than the fearless test pilots of the future.
