No.
Bicycles with external gears have chain-and-sprocket gears.
Bicycles with internally geared hubs have both a chain-and-sprocket gear and spur gears (usually in a planetary configuration) inside the rear hub.
Then there are the rather rare shaft-drive bicycles, which use bevel gears. And maybe an internally geared hub as well. Then there's the occasional belt drive bike of course. And one or two CVT designs.

What tipe of gears are on a bicycle a spur gear a bevel gear a worm gear?
Depends. Bicycles with external gears have chain-and-sprocket gears. Bicycles with internally geared hubs have both a chain-and-sprocket gear and spur gears (usually in a planetary configuration) inside the rear hub. Then there are the rather rare shaft-drive bicycles, which use bevel gears. And maybe an internally geared hub as well. Then there's the occasional belt drive bike of course. And one or two CVT designs.
What are the various forces acting on bevel gears and worm gears?
Bevel gears can change the speed and motion and Worm gears can reduce speed and direction of motion.
Did 1903 era bicycles have multiple gears?
no
What things have gear inside or outside of a objects?
Clocks and watches have internal gears. Bicycles and can openers have external gears.
What is different between spur gear and worm gear?
Spur gears give 180 degree drive, and worm gears give 90 degree drive.
How do you be the Rift worm in Gears of war 2?
There is no way to play as the Riftworm in Gears of War 2.
How do you measure the circular pitch in worm gears?
Divide 3.14 by the diametral pitch. Worm gears are a compact, efficient means of substantially decreasing speed and increasing torque.
What is the use of worm in the working of machine?
The use of worm or worm gears in the working of a machine allows for the exchange of energy for torque or movement.
What are two things that have gear in them?
Two common items that contain gears are watches and bicycles. In watches, gears work together to keep precise time by regulating the movement of the hands. Bicycles utilize gears in their transmission systems to adjust the resistance and speed, allowing for smoother pedaling across different terrains.
Where are worm gears used?
worm gears are used in machines that need high gear ratiosspoonsWorm gears are found in some kinds of 90 degree gearing junctions, generally with a large change in gearing ratio.For example, many tillers have worm gears between the input shaft and the crosswise tines.Since a motorcycle doesn't need a true differential, it may also have a worm gear connecting the drive shaft to the rear wheel.An adjustable end wrench (Crescent Wrench) also has a worm gear for adjustment, and it is easily visible.There are some devices such as a telescope stand that have precision adjustment with a worm gear, especially if the only adjust through a fraction of a circle.Worm gears are used to reduce speed. They can be found in factories. Google it to buy one.
What are different types of gears and what do they do?
There are several types of gears, including spur gears, bevel gears, helical gears, and worm gears. Spur gears are used for parallel shafts to transmit motion efficiently, while bevel gears connect perpendicular shafts and allow for changes in direction. Helical gears provide smoother operation and are suitable for higher speeds due to their angled teeth, and worm gears offer high torque and significant speed reduction in compact spaces. Each type serves specific applications based on their design and the motion they facilitate.
Does bicycles have gears?
Yes. All bikes have at least one gear, some have quite a lot more.
