The Bendix Company built a rear-wheel steering bicycle, and the U.S. Department of Transportation commissioned the construction of a rear-wheel steering motorcycle: both proved to be unrideable. Rainbow Trainers, Inc. in Alton, Illinois, offered US$5,000 to the first person "who can successfully ride the rear-steered bicycle, Rear Steered ...
A gyroscope flywheel will roll or resist about the output axis depending upon whether the output gimbals are of a free or fixed configuration. An example of some free-output-gimbal devices is the attitude control gyroscopes used to sense or measure the pitch, roll and yaw attitude angles in a spacecraft or aircraft. Animation of a gyro wheel in ...
A Jyrobike [1] (formerly known as Gyrobike [2]) is a bicycle with a special front wheel designed to make balancing easier. It was manufactured and sold by a company of the same name. The special front wheel contains a rotating flywheel driven by a rechargeable-battery-powered motor that spins at high RPMs like a gyroscope. This flywheel spins ...
Similarly, consider a nonspinning, perfectly balanced bicycle wheel mounted on a disk so that its axis of rotation makes an angle φ with the disk. When the disk undergoes a full clockwise revolution, the bicycle wheel will not return to its original position, but will have undergone a net rotation of 2π sin φ .
Section dm 2 of the wheel is moving away from the pivot axis, and so a force (again, a Coriolis force) acts in the same direction as in the case of dm 1. Note that both arrows point in the same direction. The same reasoning applies for the bottom half of the wheel, but there the arrows point in the opposite direction to that of the top arrows.
Shilovsky's gyrocar in 1914, London A gyrocar is a two-wheeled automobile.The difference between a bicycle or motorcycle and a gyrocar is that in a bike, dynamic balance is provided by the rider, and in some cases by the geometry and mass distribution of the bike itself, and the gyroscopic effects from the wheels.
The front wheel will then rotate about the steering axis to the left and the tire will generate forces in the contact patch to the left. The machine as a whole steers to the left. Because the forces in the contact patch are at ground level, this pulls the wheels "out from under" the bike to the left and causes it to lean to the right.
Wheel flop refers to steering behavior in which a bicycle or motorcycle tends to turn more than expected due to the front wheel "flopping" over when the handlebars are rotated. Wheel flop is caused by the lowering of the front end of a bicycle or motorcycle as the handlebars are rotated away from the "straight ahead" position.
