Summer Sale: 40% OFF to celebrate Bike Gears being featured in the App Stores "Apps for Cycling" section.

Designed by a cyclist, for cyclists, Bike Gears is the premier Bicycle Gear Calculator for the iPhone/iPod Touch. Calculate Gear Ratios, Gear Inches, Development and Gain Ratios using your bikes measurements. The app now has over 200 preset tire sizes and also lets you enter your own custom tire size for personalized measurements.

Building a new bike from scratch? Test out possible configurations and get it right the first time.

Find equivalent gearing configurations to reuse components you already have, or even to save weight by using smaller gears!

Want to convert your old hardtail into a single speed? No problem: take a ride on a geared bike to tweak your gear ratio, then calculate the equivalent ratio for your single-speed. Best of all, it doesnt matter if they have different tire sizes!

Enjoy skidding on your fixie? Using the Skid Patch Analyzer, you can visualize your tires wear spots and choose optimal gearing to maximize your tire longevity!

No more what-ifs, no more guestimating, and most importantly, no more costly mistakes.

Bicycle Gear Calculator is a must-have for bike builders, bike mechanics, athletes, coaches, BMX riders, commuters and alleycat racers alike! But dont take my word for it – read the reviews and see what cyclists like you are saying.

Good apps to simulate ratios, skid patch etc. Too bad there is not a single tutorial, I hope it will be in the next update.
