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.
Why does a bicycle speed up when you start pedalling?
Because when you push down on the pedals the rear wheel is forced to rotate.
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.
How do pedals function on a bicycle and what do pedals do?
Pedals on a bicycle are attached to the crank arms and are used to transfer the rider's energy into forward motion. When the rider pushes down on the pedals, the crank arms rotate, which turns the chain and ultimately drives the rear wheel. Pedals allow the rider to propel the bicycle forward by applying force with their feet in a circular motion.
How does a bicycle start?
Putting weight on the forward pedals puts tension on the chain, which rotates the rear wheel and pushes the bike forward.
What is the function of a bicycle chain sprocket in the overall mechanism of a bicycle?
The bicycle chain sprocket is a key component that helps transfer power from the pedals to the wheels, allowing the bicycle to move forward. It works by engaging with the chain and rotating as the pedals are turned, ultimately driving the rear wheel and propelling the bike.
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.
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 the purpose of the bike rear axle and how does it contribute to the overall performance of the bicycle?
The bike rear axle connects the rear wheel to the frame of the bicycle, allowing it to rotate smoothly. It plays a crucial role in supporting the weight of the rider and providing stability and control while riding. The rear axle also helps in transferring power from the pedals to the rear wheel, contributing to the overall performance and efficiency of the bicycle.
What does a bicycle chain do?
a bike chain basically does two things: it transmits power from where the rider can easily deliver it to the rear Wheel it creates a gearing ratio between how fast the pedals turn and how fast the rear wheel turns. If wheel and pedals turn at the same speed, the overall speed for the bike becomes quite limited.
What is the function of the rear cog in a bicycle's drivetrain system?
The rear cog in a bicycle's drivetrain system is responsible for transferring power from the pedals to the rear wheel, allowing the bike to move forward. It works in conjunction with the chain and front chainrings to control the speed and resistance of the bike.
What is the purpose of the rear bicycle axle and how does it contribute to the overall performance of the bike?
The rear bicycle axle connects the rear wheel to the frame of the bike, providing support and stability. It plays a crucial role in transferring power from the pedals to the rear wheel, allowing the bike to move forward efficiently. Additionally, the rear axle helps maintain proper alignment of the rear wheel, ensuring smooth and balanced riding. Overall, the rear bicycle axle contributes to the bike's performance by enhancing its speed, control, and overall functionality.
