# Your question: What is the acceleration of a bike?

Contents

## How do you find the acceleration of a bike?

a = T/(r*m1 + 2*I/r) = 100/(0.328*120 + 2*0.1965/0.328) = 2.47 m/s^2, where T = drive torque applied to rear wheel, r = wheel radius, m1 = total mass of bicycle plus human, and I = mass moment of inertia of each wheel (kg*m^2).

## Are 21 speed bikes fast?

7 Speed vs 21 Speed Bikes

In terms of how the number of gears affects the overall ride of the bike, a 21-speed is generally faster with smoother transitions and pedaling. The 7-speed is adequate for most riders, which is why many people choose the slower option.

## What is the fastest bicycle?

The list

Ranking Bike Median speed (mph)
1 Canyon Aeroad CF SLX 15.7
2 Ridley Noah SL 15.6
3 Specialized S-Works Venge 15.5
4 Sensa Romagna 15.5

## What are the physics of riding a bike?

If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy. A bicycle can convert up to 90 percent of a person’s energy and movement into kinetic energy. This energy is then used to move the bike.

## How much force does it take to pedal a bike?

Average Pedaling Force

In the above diagram, that average would be somewhere around 200 nwts or around 45 lbs.

## Which force used in cycling?

The forces resisting motion of a bicycle include rolling resistance and aerodynamic drag, together with inertia forces during acceleration and gravity forces when climbing an incline. The rider overcomes these resistances by applying forces to the pedals which are transmitted by the mechanical drive to the rear wheel.
