In the United States, all parts incorporated into the bike are high-end, similar to the parts used in expensive carbon fibre bikes. Modern machines are used to laminate, waterproof, and join the individual bamboo pieces. The Ghanaian bikes, on the other hand, use mostly parts (e.g. bamboo, chains, bolts, etc.) from low-cost sources. [8]
A plastic bicycle was an attempt in the early 1980s to introduce a bicycle made entirely out of plastic materials instead of metal. A wooden bicycle has a frame made out of wood. One example is the Chukudu used in the east of the Democratic Republic of Congo. A carbon bicycle is made of carbon fiber.
Kawasaki selected the literbike platform for its top-of-the-line Ninja H2 model, rather than continuing with the higher-displacement Ninja ZX-14 hyperbike. Cycle World's Kevin Cameron explained that the literbike class is "the center of the high-performance market", attracting the best development in racing, with the best chassis and suspension design, so it made sense for Kawasaki to create a ...
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.

From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
