A carbon fiber frame racing bicycle by the French company LOOK A road bicycle made by Scott Lance Armstrong riding in a posture often used on a road bicycle. A racing bicycle, also known as a road bike, is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI).
The track bicycle made by Pinarello that Bradley Wiggins rode to break the hour record in June 2015. A track bicycle or track bike is a bicycle optimized for racing at a velodrome or outdoor track. Unlike road bicycles, the track bike is a fixed-gear bicycle; thus, it has only a single gear ratio and has neither a freewheel nor brakes.
A folding bicycle is a bicycle designed to fold into a compact form, facilitating transport and storage. When folded, the bikes can be more easily carried into buildings, on public transportation (facilitating mixed-mode commuting and bicycle commuting ), and more easily stored in compact living quarters or aboard a car, boat or plane.
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.

E.g., a reduction of 10% of the total system weight (bicycle, rider, and luggage combined) will save nearly 10% power. A reduced mass is also directly felt when accelerating. For example, the Analytic Cycling calculator Archived 2022-01-15 at the Wayback Machine gives a time/distance advantage of 0.16 s/188 cm for a sprinter with 500 g lighter ...
It has about the same wind resistance as a conventional bicycle. High-performance tandems may weigh less than twice as much as a single bike, so the power-to-weight ratio may be slightly better than that of a single bike and rider. On flat terrain and downhill, most of the power produced by cyclists is used to overcome wind resistance, so ...

Many new mountain bikes integrate a "full suspension" design known as dual suspension, meaning that both the front and rear wheel are fitted with a shock absorber in some form as the wheel attaches to the bike. This provides a smoother ride as the front and rear wheels can now travel up and down to absorb the force of obstacles striking the tires.
