Bicycles - the drivetrain

 

Bicycles - formulae

Gear inch = ( chainwheel / freewheel ) x wheel diameter (inches) x p

where chainwheel = number of teeth in the chainwheel in use

freewheel = number of teeth in the freewheel in use

Vfps = Gear inch x RPM x .00139      Bicycle speed in feet per second

or using the Metric

convert gear inch to gear centimeters ( multiply inches by 2.54 )

Vmps = Gear cm. x RPM x .017      Bicycle speed in metres per second
