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 ...
Diagram of a gyro wheel. Reaction arrows about the output axis (blue) correspond to forces applied about the input axis (green), and vice versa. 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 ...
Tall bike (often called an upside down bike, constructed so that the pedals, seat and handlebars are all higher than normal)—other types of tall bikes are made by welding two or more bicycle frames on top of each other, and running additional chains from the pedals to the rear wheel. Come-apart bike, (essentially a unicycle, plus a set of ...
Portage strap: a strap (usually made of leather) attached to the inside of the bike frame, designed to make carrying the bike over one's shoulder easier; Pulley wheel: see Jockey wheel; Power meter: a device on a bicycle that measures the power output of the rider; Quick release: a skewer with a lever on one end that loosens when the lever is ...

"That was me on a bike on a crane arm on a soundstage with a blue screen behind me," the now-50-year-old actor tells Yahoo Entertainment ahead of E.T.'s fortieth anniversary. "I was just up and ...
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. Foucault-like precession is observed in a virtual system wherein a massless particle is constrained to remain on a rotating plane that is inclined with respect to the axis of ...
