Bicycle Gear Ratio App

Bicycle Gear Ratio App is a bicycle gear calculator. It helps you to find the optimal gearing for your bicycle and compare multiple gearings with each other. 
 
The gear calculator displays:
- number of gears,
- all combinations of given gearing system,
- gear ratio,
- gear inches and gear meters,
- speed (mph and km/h),
- comparison between different gearing systems.

Wheels and tyre size can be chosen out of given list. There is a blank field RPM that you must fill out with revolutions per minute. Next you must choose number of chainrings and fill them out with chainring size. Last you must choose number of cogs in the cassette. You can fill out blank fields manually or can choose one out of given list - you can also customize it.

You can compare gearing systems by clicking 'ADD BICYCLE' button and fill out the form.
