New Version of ANT+ Bike Power Profile Provides Advanced Data Metrics to Analyze Efficiency

Bike power sensors with ANT+ can now report pedal smoothness and torque effectiveness

Cochrane, Alberta (PRWEB) February 14, 2013 -- ANT Wireless ("ANT", a division of Dynastream Innovations Inc., today announces a new version of the ANT+ Bike Power profile that now allows ANT+ enabled bike power sensors to report advanced data metrics including Torque Effectiveness and Pedal Smoothness in real time.

The new capabilities of the Bike Power profile provide cyclists with greater opportunity to analyze power efficiency and performance of each leg. Specifically, Torque Effectiveness now measures the percentage of force used to pull up and push down the left and right pedals.  Pedal Smoothness calculates the percentage of how evenly a cyclist applies power throughout their pedal stroke based on left/right or overall measurements. Both features are integrated within an ANT+ bike power sensor mounted on either the pedal or crank of a bike. The sensor calculates the power in Watts required to move the bike forward and transmits the information to an ANT+ enabled display device such as a bike computer, watch, cell phone or fitness equipment computer. The data can be viewed in real time or stored for later analysis.

“We continually push and expand the capabilities of ANT+ technology so that we can produce valuable data and device functionality, said ANT Wireless Vice President, Rod Morris. “We’re proud to bring these leading advancements to cycling while always staying committed to ANT+ interoperability, ease of use and backwards compatibility.”

These new features bring a new level of ANT+ detail and interoperability to the cycling enthusiast.  Now it is possible to see how much applied power and resistance is expended per leg and train accordingly.  Based on the individual measurements, athletes and coaches can now identify the rider’s style, determine which pedal stroke yields the best results and optimize performance.  Because the profile is ANT+ based, this advanced functionality can now be integrated into leading ANT+ products and the already-established ecosystem of sport, fitness and health devices.  

Rotor Bike Components’ newly released crank-based power meter, Rotor Power, is the first certified ANT+ product to utilize the new Bike Power profile. 

“Our aim is to give cyclists the tools they need to maximize their performance,” said Rotor’s Engineering Manager, David Martinez Garcia. “The new features of the ANT+ Bike Power profile allow us to do that by enabling a unique and interoperable solution where our customers can receive essential power efficiency data in real time.”
