Get Dialed In with the NEW Kurt Kinetic Wired Power Computer! The Kinetic Wired Power Computer is designed to give you accurate power (watt) readings when you are using a Kinetic Trainer. All other functions (speed, distance, cadence, calorie burn, altimeter, etc) are accurate both on and off the trainer. Because of this, the Kinetic Power Computer is an excellent choice for a cycling computer both on and off the trainer. The watts reading is calibrated based on a mathematical relationship between power and speed. This Kinetic Power Formula along with our proprietary software accurately estimates the cumulative effect of 16 different interactive forces. This power curve is based on the "average " rider on the "outdoor ride" using the following cubic function: P = (5.244820) * S + (0.01968) * S3. S=speed in miles per hour, P=power in Watts, IN THE BOX: Computer, Stem / Handlebar Mount, Speed Transmitter w/magnet, Cadence Transmitter w/Magnet, Battery, Cable Ties.
