SRAM manufactured the i-Light hub dynamo until 2017. [3] The D7 series was available for both rim and disc brakes while the D3 series featured several rim brake varieties. In a 2006 review by the German Stiftung Warentest , the efficiency at 15 km/h (9 mph) of a D1 series i-Light hub dynamo was 66%, 10% better than a SON-28.
Red light on the back of a bicycle Early bicycle lighting: candle lamps, oil lamps and carbide lamps Early bicycle lamps and two early bottle dynamos (1935). Bicycle lighting is illumination attached to bicycles whose purpose above all is, along with reflectors, to improve the visibility of the bicycle and its rider to other road users under circumstances of poor ambient illumination.
A hub dynamo enables a built-in lighting system without the loud noise and high drag of a bottle (sidewall) dynamo, and without the unreliability, high cost, ecological disposal problem, and maintenance inherent with batteries. The hub dynamo powers LED or halogen front and rear lights.
Schmidt hub dynamo disk brake. ... (SON) is a manufacturer of high-efficiency and low-drag bicycle hub power generators and other electric bicycle gear. [1] [2] [3 ...
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 .
Hub dynamo: a generator inside one of the hubs for powering lights or other accessories; Hub gear: a gearbox mounted inside the hub, 3-speed is common, 5, 7 are available ("Sturmey-Archer"), Enviolo makes a CVT, and Rohloff makes a 14-speed hub. Cable operated by one or two cables; Indicator: a turn signal
The firm pioneered the dynamo-charged battery principle and in 1911 it produced the world's first lighting system used on a double-decker bus. [12] By 1918 1,000 employees were making vehicle electrics and aircraft magnetos. [12] Wireless components were also made from 1923. [12] In 1926 CAV was bought by Lucas. [12]
A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo, supplying electric current to an incandescent bulb or light-emitting diode. The flashlight must be pumped ...
