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.

A balance bike (or run bike) is a bicycle without pedals that learners propel by pushing their feet against the ground. [1] By allowing children to focus on developing their sense of balance and coordination before introducing pedalling, balance bikes enable independent riding more quickly than training wheels .

A rowing cycle is driven by a rowing action using both arms and legs. A treadle bicycle is driven by a reciprocating, not rotary, motion of the feet. A bucking bike (with one or more eccentric wheels ...
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 ...
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 ...
Gear inches is an imperial measure corresponding to the diameter in inches of the drive wheel of a penny-farthing bicycle with equivalent (direct-drive) gearing. A commonly used metric alternative is known as metres of development or rollout distance , which specifies how many metres a bicycle travels per revolution of the crank.
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 ...
