A wheel with a radius of 0.5m has a circumference of 2πr metres.
In this example, 2πr = 2π x 0.5 = π metres.
The wheel makes 100/π turns when travelling 100 metres, that is 31.831 turns.

First you have to know the distance you wish to travel. Then you simply calculate the circumfrance of the tire. (2pie*radius) which would give you around 4.77 inches. Divide the distance you want to go by 4.77 and you get the proper amount of turns.
You would need 317 pedal turns are needed to travel a mile on a bicycle.
A bicycle odometer was once a mechanical instrument that counts the number of turns of the wheels, and shows the total distance travelled. Nowadays, a bicycle computer does the same thing, but digitally, and showing more than simply distance travelled.

50 / 3 = 16.66666 5280 / 16.66666 = 316.8 317 pedal turns check it by 316.8 / 3 = 105.6 105.6 * 50= 5280
Need to find:Distance wheel travels in 1 turn = circumference of wheelcircumference = π × diameter → diameter = circumference ÷ π333 ft ÷ 37 turns = 333/37 ft/turndiameter = 333/37 ft ÷ π ≈ 2.86 ft
get the circumference of the circle using 2*pi*r (1.2*pi) times that by 40 to get the answer (48*pi)
radius of coil....number of turns
The circumference of the wheel is Pi multiplied by the diameter (0.705). Divide 1000 meters (1km) by that answer - and you'll have your solution !
bi means 2 and cycle, cyclic means something that turns, rotates. Two spinning wheels, that's a bicycle.
He uses it to get back in the Grimes Building later.
