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.

Wheelbase (measured between rotational centers of wheels) Bike geometry parameters: The wheelbase of a bicycle. In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the ...
The name "29er" comes from a bicycle called the Two Niner, which was offered by the Fisher bike company in 2001, according to 1998 Mountain Bike Hall of Fame inductee Don Cook. [8] The US division of Bianchi Bicycles offered a line of 29″ wheeled off-road bikes beginning in 1991 called the Project bikes. Their 1992 product catalog raved about ...
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 ...
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.
A RANS V2 Formula long-wheelbase recumbent bike fitted with a front fairing Shop for recumbents in Nijmegen, Netherlands. A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position. Recumbents are available in a wide range of configurations, including: long to short wheelbase; large, small, or a mix of wheel sizes ...
Investigators are trying to determine how a woman got past multiple security checkpoints this week at New York’s JFK International Airport and boarded a plane to Paris, apparently hiding in the ...
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 ...
