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 .
The seat post attaches to the seat rails by means of a clamp; Seat lug: a frame lug on the top of the seat tube serving as a point of attachment for a clamp to secure the seat post; Seat tube: the roughly vertical tube in a bicycle frame running from the seat to the bottom bracket; Seat bag: a small storage accessory hung from the back of a seat
Bicycle dynamos instead use permanent magnets to eliminate the need for a battery to excite the field and initiate electrical generation. Shimano offers a variety of hub dynamos under the "Nexus" brand, such as the DH-3N70/DH-3N71, advertised as having significantly less drag than the Nexus NX-30. SRAM manufactured the i-Light hub dynamo until ...
Most commonly, a small magneto, termed a bottle dynamo, rubs against the tire of the bicycle and generates power as the wheel turns. More expensive and less common but more efficient is the hub dynamo that rotates neodymium magnets around a copper coil in a claw pole cage inside the hub of a wheel.
All Sturmey-Archer gear hubs use epicyclic (planetary) geartrains of varying complexity. The AW is the simplest, using one set of planetary gears with four planets. The AM uses three compound planets with differently sized cogs machined from a common shaft to engage the gear ring and sun gear separately, while the close-ratio three-speeds, and hubs with four or more speeds, use multiple ...

A bicycle saddle, sometimes called a bicycle seat, is one of five contact points on an upright bicycle, the others being the two pedals and the two handles on the handlebars. (A bicycle seat in the specific sense also supports the back.) [ 1 ] The bicycle saddle has been known as such since the bicycle evolved from the draisine , a forerunner ...
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 .
