What is a bicycle gear?
On a bike there's one(or more) front sprocket(s) by the pedals connected by a chain to one(or more) rear sprocket(s) by the rear wheel. As the wheel isn't driven directly by the pedals, and there's usually a difference in size between the front & rear sprocket this constitutes a gear.
Do fixed gear bikes have brakes?
Fixed gear bikes typically do not come with brakes, as the pedals are directly connected to the wheel. Riders can slow down or stop by using their leg muscles to resist the motion of the pedals. However, some fixed gear bikes may be equipped with a front brake for added safety.
What happens to the speed of the wheel to a bike when you take into higher gear?
If you keep the pedals turning at the same rate, then a higher gear will make the rear wheel turn faster. But it will also be harder to push the pedals
What is a gear chain on a bicycle?
Put simply... it's a circle of links that connects the drive gear (attached to the pedals) to the speed gear(s) - attached to the rear wheel. Rotating the drive gear (using the pedals) transfers the movement to the gear cogs on the rear wheel - which propels the bicycle forwards.
What happens to power if you go from a big gear to a small gear?
If you move from a big chainwheel to a smaller chainwheel by the pedals, pushing the pedals will get easier. If you move from a big sprocket to a smaller sprocket by the rear wheel, pushing the pedals will get heavier.
Why does the rear wheel of a bicycle turn faster than the pedals?
because of the gear ratio and the chain
Why is the rear gear on a bike smaller than the gear found by the pedals?
Because for most types of riding you want the rear wheel to turn faster than the pedals, and that is achieved by running the chain over a larger sprocket at the front and a smaller sprocket at the rear. By having this difference in gear ratio you get a useful travelling speed at a comfortable pedalling pace (and strain).
Does wheel size affect speed?
yes . imagine a big gear (which is connected to a small gear) turning one round, the smaller gear turns...10 rounds perhaps? If a big gear is attached to a motor and than a small gear is connected to it as a wheel, the vehicle will move around ten times faster than when the wheel gear is big.
How bicycles works?
A bicycle is one of the most efficient forms of transport. It works with pedals, which are connected via a chain to the back wheel. The rotation of the pedals moves the chain across gears on the rear wheel, rotating it. To change the gear ratio, the chain is moved to different sized gears of the wheel. The steering works by rotating the front wheel using the handle bars, reorienting the bicycle in a different direction. The brakes work with cables, pulling two rubber plates against the wheel. Newer models have circular plates, which lock onto the spokes of the wheel. This prevents the rubber from being worn down, and is more efficient.Manpower.Bicycle uses mechanical energy. It takes the principle of axle and chain. When we paddle, the chain rotates the axle and the wheel also revolves.The pedals on a bike are connected to a gear that turns the chain. The chain is also connected to a gear that is attached to, and therefore turns, the rear wheel. The rear gears are set up so that when turning forward the will turn the wheel but when turning backward or not moving at all the gears have no effect on the wheel. Different gears are used to gain more speed - a larger gear at the front means the smaller gear at the back will turn faster.bicycles work through a series of gears and pulleys that move when you petal your petals. When they move the gears and pulleys move thus making the wheels move, propelling you forward so long as you're balanced. that is how a bicycle works.
How do the number of gear teeth affect the wheel on a bicycle?
The more teeth you have on the chainring(by the pedals) when compared to the sprocket(on the rear wheel, the more the rear wheel will turn for each turn of the cranks.
How does the bike chain gear system work to transfer power from the pedals to the wheels?
The bike chain gear system uses a chain to connect the pedals to the gears on the rear wheel. When you pedal, the chain moves and turns the gears, which in turn rotate the wheel, transferring power from your pedaling to the wheels, propelling the bike forward. Different gear combinations allow for varying levels of resistance and speed.
Putting a new chain on a mountain bike where is first gear?
First gear on a bicycle with external/derailer gears is with the chain on the smallest chainwheel(by the pedals) and the biggest sprocket(by the rear wheel).
