When you ride a bike, you are pushing on the pedals, and they are connected to gears, which cause the wheels to turn. The bike doesn’t move by itself. To be in motion, the bike needs to have you put force on it by pedaling. … Inertia is not a force, but it changes the way things can be pushed or pulled.
What is the correct way to pedal a bike?
Pull your pedals in semicircles
“Normally the most important aspect of pedalling is to pull backwards at the bottom of the pedal stroke. As the pedal moves towards the bottom switch from a pushing down motion to a pulling back movement. Cyclists are often told to try to pedal in circles. This should be avoided.
What force is used when riding a bike?
Turning on a bike requires a net force called centripetal force. The frictional force provides the centripetal force necessary to turn the cyclist to the left. But the frictional force also produces a clockwise torque that will cause the rider and bicycle to tip clockwise to the right.
What will happen to the bicycle when you push the pedal faster?
As we pedal faster, our muscles become less efficient and lose more energy as heat. Our efforts to keep cool by sweating also take up energy. How dramatic this loss of efficiency with increased power will be depends on a person’s cardiovascular fitness.
What does a beginner cyclist need?

Why do bikes stop when pedaling?
When the rider stops pedalling the bicycle, the force of friction between the tyres of bicycle and the road acting in the direction opposite to the direction of motion of the bicycle, opposes the motion of the bicycle and this force is now unbalanced, thus slowing down the bicycle.
Where should your feet be on bike pedals?
When placing your foot on a flat pedal, the ball of your foot should be just in front of the pedal spindle. Basically the spindle of the pedal should support the back section of the meaty part of the ball of your foot.
Should your feet touch the ground when sitting on your bike?
When you sit on the saddle, both feet should reach the floor and the balls of your feet should be touching the ground. … The handle bars on your bike should ideally be in line with your saddle or slightly above the saddle.
Is riding a bike a balanced force?
When you ride a bike the force of the friction of the tires against the road is greater than the opposing force of friction with the air. The bicycle moves forward. This is an example of unbalanced forces. How do you know when forces are balanced?

Is a lighter bike faster?
In fact, he did the math to see just how much speed a cyclist can save with a lighter bike. … Even at the steepest grade he tested (7 percent), a one-pound difference between bikes only saves about 2.5 seconds—and the lightest bike only reaches the top 7.5 seconds faster than the heaviest one.
What two forces make a cyclist slow down?
When biking on a level road, your forward force comes from pushing and pulling on the pedals to make the back tyre push backwards against the road. The two main forces that oppose your motion are aerodynamic drag (air resistance) and rolling resistance of the tyres against the road caused as the tyre is compressed.
How fast can a pedal bike go?
With medium effort a cyclist can pedal 8 – 10 KPH up a gentle incline. Riding on grass, sand, mud, or snow will also slow a rider down. Without pedaling downhill a bicycle rider can easily reach speeds of 20 – 40 kilometers per hour down a gentle %5 slope and dangerous speeds exceeding 50 KPH on steeper inclines.
