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 ...
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of ...
Photograph of a physical implementation Detail of front end. 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.
Huck bikes or Extreme Freeride bicycles are highly customized bicycles whose design, construction and style is similar to that of motocross-style motorcycles. With an heavily reinforced frame, with very long travel suspensions (more than 200 mm / 8″ in the front fork, and rear suspension), large tires (more than 2.5″ x 26″ or 24″).
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 combined center of mass of the bike and rider is only lowered and not moved out, but if the front of the bike is free to swivel about its steering axis, the lean to the right will cause it to steer to the right by some combination of gyroscopic precession, ground reaction forces, gravitational force on an off-axis center of mass or simply ...
