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.
Between the two unstable regimes mentioned in the previous section, and influenced by all the factors described above that contribute to balance (trail, mass distribution, gyroscopic effects, etc.), there may be a range of forward speeds for a given bike design at which these effects steer an uncontrolled bike upright.

This flywheel spins significantly faster than the front wheel rolls and acts as a gyroscope, even when the bike is moving slowly, such as when the rider is starting. The flywheel causes the front wheel to respond to a lean by precessing , that is the front wheel turns toward the direction of the lean, which can help provide stability at low ...
One effect of turning the front wheel is a roll moment caused by gyroscopic precession. The magnitude of this moment is proportional to the moment of inertia of the front wheel, its spin rate (forward motion), the rate that the rider turns the front wheel by applying a torque to the handlebars, and the cosine of the angle between the steering ...
Since shimmy frequency is independent of bike speed, gyroscopic effects "are clearly not essential to the phenomenon." [ 2 ] The top five influences on wobble have been found to be lateral stiffness of the front tire, steering damper, height of bike center of mass, distance of bike center of mass from rear wheel, and cornering stiffness of the ...
A gyroscope is an instrument, consisting of a wheel mounted into two or three gimbals providing pivoted supports, for allowing the wheel to rotate about a single axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow a wheel mounted on the innermost gimbal to have an orientation remaining ...
Lit Motors Inc. is a San Francisco-based startup founded by Daniel K. Kim in 2010. Lit Motors designs conceptual two-wheeled vehicles with a focus on innovative technologies, including the AEV (Auto-balancing Electric Vehicle), often referred to as the "C-1," a fully electric, gyroscopically stabilized vehicle, [1] and the Kubo cargo scooter.

A two-mass-skate bicycle (TMS) is a theoretical model created by a team of researchers at Cornell University, University of Wisconsin-Stout, and Delft University of Technology to show that it is neither sufficient nor necessary for a bike to have gyroscopic effects or positive trail to be self-stable.
