Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase , steering axis angle, fork offset, and trail.
In a traditional-geometry diamond frame, the top tube is horizontal (parallel to the ground). In a compact-geometry frame, the top tube is normally sloped downward toward the seat tube for additional standover clearance. In a mountain bike frame, the top tube is almost always sloped downward toward the seat tube. Radically sloped top tubes that ...
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 ...
It has a more slack geometry and fatter tires than a road bike. It is generally used to tackle more rough terrain than cyclo-cross bicycles. Gravel bicycle frames also use characteristics of both cyclocross and road bikes for better comfort on long rides and the wheel clearance to accommodate rides done in torrential conditions. [1]

A bicycle dropout (drop out, frame end, or fork end), is a slot in a frame or fork where the axle of the wheel is attached. The term fork is sometimes also used to describe the part of a bicycle that holds the rear wheel, [1] which on 19th century ordinary or penny-farthing bicycles was also a bladed fork.
Wilbur Wright explained countersteering this way: I have asked dozens of bicycle riders how they turn to the left. I have never found a single person who stated all the facts correctly when first asked. They almost invariably said that to turn to the left, they turned the handlebar to the left and as a result made a turn to the left.
Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, ...
