A sprocket is another name for a toothed wheel that meshes with the chain.
There are three main types of electric bicycle gears available on the market: hub gears, derailleur gears, and continuously variable transmission (CVT) gears. Hub gears are enclosed within the rear hub of the wheel, derailleur gears use a system of sprockets and a chain to change gears, and CVT gears offer a smooth and seamless transition between gear ratios.
The different types of bicycle sprockets available in the market include single-speed sprockets, cassette sprockets, freewheel sprockets, and fixed-gear sprockets. Each type serves a specific purpose and is compatible with different types of bicycles.
An example of simple gears is the chain, chain-wheel and free-wheel sprocket as used on a single geared bicycle. More complicated gearing is the modern bicycle's derailleur system of multiply chain-wheels, a cluster of sprockets, a chain, and gear changer mechanism.
Derailleur gears work by using a mechanism to move the chain from one sprocket to another on a bicycle. When the rider shifts gears, the derailleur moves the chain sideways, allowing it to engage with a different sprocket, which changes the gear ratio and makes pedaling easier or harder.
there are no sprockets on a carFeel free to correct me but I believe cars with timing chains have sprockets. Anyway, typical sprockets would be the gear-like pulleys that a bicycle chain runs on. They are considered different from gears in that they do not mesh directly, but use a chain or other device to connect them.Also I believe the power window feature of a car uses a sproket assembly.
To enhance a single-speed bicycle by adding gears, you can install a gear system called a derailleur. This system allows you to change the gear ratio by shifting the chain between different sized sprockets on the rear wheel. Gears provide more options for adjusting your pedaling effort to different terrains, making your ride more efficient and comfortable.
Derailleur gears in a bicycle's transmission system work by moving the chain between different sized sprockets on the rear wheel and front crankset. This changes the gear ratio, allowing the rider to pedal more easily or with more power depending on the terrain. The derailleur mechanism is controlled by shifters on the handlebars, which move the chain to different gears by adjusting the tension in the derailleur cables.
If they're all inside the hub they're called internal gears, and consist of something mechanics refer to as "planetary" gears. If they are toothed discs that sit outside the hub they're called sprockets. The whole assembly is either a multi-speed freewheel. or a "cassette" for a freehub.
The usual formula is no of chainwheels(up by the pedals) x no of sprockets(on the rear hub). But what's getting more common is to separate the two, and just to say that your bike is a 3x9 for instance.
No way to answer that w/o knowing where you live.
Yes, it is possible to install a motor on a bicycle equipped with gears.
That bicycle has 18 gears.
