2. Bottle dynamo - Wikipedia

   en.wikipedia.org/wiki/Bottle_dynamo

   A bottle dynamo or sidewall dynamo is a small electrical generator for bicycles employed to power a bicycle's lights. The traditional bottle dynamo (pictured) is not actually a dynamo at all (which creates DC power), but a low-power magneto that generates AC. Newer models can include a rectifier to create DC output to charge batteries for ...

3. Dynamo - Wikipedia

   en.wikipedia.org/wiki/Dynamo

   "Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...

4. Electric bicycle - Wikipedia

   en.wikipedia.org/wiki/Electric_bicycle

   An electric bicycle, e-bike, electrically assisted pedal cycle, or electrically power assisted cycle[1] is a motorized bicycle with an integrated electric motor used to assist propulsion. [2][3][4][5][6] Many kinds of e-bikes are available worldwide, but they generally fall into two broad categories: bikes that assist the rider's pedal-power (i ...

5. Bicycle performance - Wikipedia

   en.wikipedia.org/wiki/Bicycle_performance

   Bicycle performance is measurable performance such as energy efficiency that affect how effective a bicycle is. Bicycles are extraordinarily efficient machines; in terms of the amount of energy a person must expend to travel a given distance, cycling is calculated to be the most efficient self-powered means of transportation. [1] The transport ...

6. Hub dynamo - Wikipedia

   en.wikipedia.org/wiki/Hub_dynamo

   Hub dynamo. A hub dynamo is a small electrical generator built into the front hub of a bicycle wheel that is usually used to power lights. Often the hub "dynamo" is not actually a dynamo, which creates DC, but a low-power magneto that creates AC. Most modern hub dynamos are regulated to 3 watts at 6 volts, although some will drive up to 6 watts ...

7. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   In electricity generation, a generator[1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even ...
