Lemond Fitness Watt Box Power Sensor
The Lemond Watt Box power sensor lets you use your LeMond Revolution to accurately measure your power wirelessly to any ANT+ enabled device. The LeMond WattBox will work with all Revolution models.
Cyclists have turned to watt-based training to develop a better sense of their actual efforts allowing them to better understand and modulate their power output. The Revolution’s Direct Drive system naturally allows for a accurate way to measure power.
First, the aerodynamic resistance is determined by measuring the speed of the flywheel and also involves a function that measures air density. Mechanical losses are also considered as the belt used to spin the flywheel has a mild temperature dependence and there is a slight bit of bearing resistance. Finally, mechanical resistance from the drive-train is entered into the equation.
All the internal sensors are carefully calibrated. Although not required, a cadence sensor aids in the calculations. If not used, the Watt Box may still indicate power being placed on the pedals while coasting.
LeMond Fitness was formed in 2002 by Greg LeMond. Our main office is located in Woodinville, Washington, USA. Under Greg’s leadership, LeMond Fitness is continuing Greg's passion for developing exciting new products that help individuals achieve their fitness goals and train more effectively. As the first American to win the Tour de France, Greg transformed the world of cycling. LeMond Fitness bikes reflect Greg’s same passion for cycling products that break out of the mold. Tired of indoor training and exercise bikes that have nothing to do with cycling at all, Greg has reinvented this product category – making LeMond Fitness the industry gold standard for high quality and exceptional performance in stationary cycles. Designed like great road bikes, all Lemond Fitness exercise and training bikes offer user-friendly adjustments and innovative cycling programs to make a workout and training program more effective. We also believe in giving back ... supporting young cyclists, helping athletes train, and working with kids to instill a lifelong appreciation of the power of being fit.
