Some examples of the types of bikeways under the purview of bicycle transportation engineers include partially segregated infrastructure in-road such as bike lanes, buffered bike lanes; physically segregated in-road such as cycle tracks; bike paths with their own right-of-way; and shared facilities such as bicycle boulevards, shared lane ...
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 ...
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 ...
The New York City Department of Transportation implemented a bicycle path and traffic calming pilot project for Prospect Park West in Brooklyn in 2010 and published their results in early 2011. It created a two-way bicycle path with a 3 foot (0.91 m) parking lane buffer and the removal of one lane from motor vehicles.
Before epicyclic gears were used in bicycle hubs, they were used on tricycles. Patents for epicyclic hubs date from the mid-1880s. [5] [6] The first patent for a compact epicyclic hub gear was granted in 1895 to the American machinist Seward Thomas Johnson of Noblesville, Indiana, U.S.A. [7] This was a 2-speed but was not commercially successful.

The FAA told airlines late Wednesday that the reduction from a maximum of 28 to 26 arrivals per hour would reduce risk but also increase average delays from 40 minutes to 50 minutes.
A bicycle sharing system, public bicycle system, or bike share scheme, is a service in which bicycles are made available for shared use to individuals on a very short-term basis. Bike share schemes allow people to borrow a bike from point "A" and return it at point "B". Many of the bicycle sharing systems are on a subscription basis.
