Steering motions included "balance", in which both wheels move together to steer the tire contacts under the center of mass; and "true circle", in which the wheels steer equally in opposite directions and thus steering the bicycle without substantially changing the lateral position of the tire contacts relative to the center of mass.
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century there were more ...
In transport engineering nomenclature, a counterflow lane or contraflow lane is a lane in which traffic flows in the opposite direction of the surrounding lanes. Contraflow lanes are often used for bicycles or bus rapid transit on what are otherwise one-way streets. In a sample configuration for buses, a street might have four lanes: the ...
15-mile Penny Farthing Race, Harvard University Cycling Association in 1887 A penny-farthing in the Škoda Auto Museum, Czech Republic. The penny-farthing, also known as a high wheel, high wheeler or ordinary, is an early type of bicycle. [1]
Bucking bike (with one or more eccentric wheels) 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.
A fixed-gear or track-bike hub includes special threads for a lockring that tightens in the opposite (counter-clockwise) direction compared with the sprocket. This ensures that the sprocket cannot unscrew when the rider "backpedals" while braking. [61] A horizontal dropout on a steel frame road bicycle converted to a single-speed. The ...
Note that, on a bicycle, as rake angle increases, head angle decreases. Trail can vary as the bike leans or steers. In the case of traditional geometry, trail decreases (and wheelbase increases if measuring distance between ground contact points and not hubs) as the bike leans and steers in the direction of the lean.

Lane splitting is riding a bicycle or motorcycle between lanes or rows of slow moving or stopped traffic moving in the same direction. [1] [2] It is sometimes called whitelining, or stripe-riding. [3] [4] This allows riders to save time, bypassing traffic congestion, and may also be safer than stopping behind stationary vehicles. [2] [3] [5] [6]
