BMX Gear Calculator

Many years ago at bmxultra.com we started to develop a gear chart and a gear calculator specifically for BMXers that could be used on the web, so no matter where you were, providing you had an internet connection and a browser, you could access them. Of course over the years they have changed somewhat. Now the calculator produces an interactive gear chart, which sounds very complicated but couldn't be easier to use. Not only that though, the calculator can give you exact roll out for Tioga PowerBlock tires and many other popular tires.

Since we use it a lot ourselves we are very proud of what we have been able to produce and how popular it is.

Every now and then, while at some tracks we found that internet connections on the phone were very slow making the gear calculator a little difficult to use. It's been a long time coming but we finally have our first iPhone/iPad app, the BMX Gear Calculator

- the BMX specific gear calculator that works anywhere, anytime
- no internet connection required
- compare multiple gears in a simple chart on the one screen
- includes:
