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).
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 ...
The HighCycle was an exercise bike that a user would pedal through a virtual landscape. If the user pedaled fast enough, the virtual bike would take off and fly over the landscape. Virtual Racquetball tracked the position and orientation of an actual racquet that was used to hit a virtual ball in a virtual environment. This environment was ...
Exercise bikes are used for exercise, to increase general fitness, for weight loss, and for training for cycle events.

The low-impact movement involved in operating an exercise bike does not put much ...
Physical exercise results in numerous health benefits and is an important tool to combat obesity and its co-morbidities, including cardiovascular diseases. Exercise prevents both the onset and development of cardiovascular disease and is an important therapeutic tool to improve outcomes for patients with cardiovascular disease.
Bikes with negative trail exist, such as the Python Lowracer, and are rideable, and an experimental bike with negative trail has been shown to be self-stable. [1] In motorcycles, rake refers to the head angle instead, and offset created by the triple tree is used to diminish trail. [43] A small survey by Whitt and Wilson [28] found:
On roads where adjacent bike paths or cycle tracks exist, the use of these facilities is compulsory, and cycling on the main carriageway is not permitted. [19] Some 35,000 km of cycle-track has been physically segregated from motor traffic, [20] [21] equal to a quarter of the country's entire 140,000 km road network. [22]
