SoundOfMotion.com has just released a beta version of a cycle computer application for mobile phones.The application runs on any Java enabled mobile phone with Bluetooth for wireless connectivity to a specially designed sensor attached to a bicycle's wheel.

The beta program will allow early adopters to download application from SoundOfMotion.com to their mobile phones and test it with a wheel sensor simulator. 

The Bluetooth wireless sensor is designed to detect micro-motion and calculate speed, acceleration and distance traveled more accurately than traditional cycle computers. The data could also be stored and uploaded to a computer for training analysis.The mobile phone is positioned on a handle bar with a specially designed mounting base. It could also be connected to a dynamo, charging your phone while riding.

The sound simulation technology allows MP3 enabled phones to play various sound themes through a mini-amplifier, attached to the phone mounting base, according to the cyclist's speed and acceleration. Current sound themes simulate motorcycle, horse and steam train. Like ringtones, users could also compose their own sound themes, expressing their creativity with a sound of motion. Riders could easily control the sound volume without taking their hands off the handle bar.

The final product for bicycles is scheduled to be on the market this summer.
