One documented example of someone successfully riding a rear-wheel steering bicycle is that of L. H. Laiterman at Massachusetts Institute of Technology, on a specially designed recumbent bike. [28] The difficulty is that turning left, accomplished by turning the rear wheel to the right, initially moves the center of mass to the right, and vice ...
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 ...
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.
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.

The front wheel from a racing bicycle. Bicycle wheel with wooden rim Nipples Spokes Cross-section of a rim A Shimano Dura-Ace freehub-style hub. A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels.
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 ...
Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios .
The motion dynamics of a bicycle will cause a transfer of weight to the front wheel during braking, improving the traction on the front wheel. If the front brake is used too hard, momentum may cause the rider and bike to pitch forward – a type of crash sometimes called an " endo ".
