Kinetic by Kurt Wireless Power Computer Feature

• Kinetic Wireless Power Computer is designed to give you accurate power (watt) readings when using a Kinetic Trainer.
• All other cyclo computer functions (speed, distance, cadence, calorie burn, etc.) are accurate both on and off the trainer
• Heart rate monitor built into the Power Computer. Chest strap included.
• Comes with computer, stem/handlebar mount, speed transmitter w/magnet (wireless), cadence transmitter w/magnet (wired), battery, Cable Ties, and chest strap (heart rate monitor).
• Watts reading is calibrated on the following mathematical equation: P = (5.244820) * S + (0.01968) * S3 where S=speed and P=power

The Kinetic Wireless 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" ride on the "outdoor ride" using the following cubic function: P=(5.244820) * S + (0.01968)*S3. S=speed in mile per hour, P=power in Watts. Features include: -Wireless -Speed -4 Keys -Auto Start -Max. Speed -Speed bar (% of max. speed) -Average Speed -Speed Comparison -Distance 1 -Distance 2 -Odometer 1 -Odometer 2 -Odometer 1 + 2 -Ride Time 1 -Ride Time 2 -Distance Countdown -Time to arrival (arrival time/time remain) -% to arrival (Bar Display) -2nd wheel size -Time (12/24hr) -Auto Sleep -Heart Rate -Max Heart Rate -Average Heart Rate -Upper/Lower Limit w/ visible alarm -Calorie -Fat burn -Stopwatch -Auto Lap (Time/Distance) -Altimeter -Home Altitude storage -Altitude gain/loss -% gradient -Power -Max Power -Average Power -Temperature (C/F) -Max Temperature -Min Temperature -Easy Calibration -Service interval reminder -EL Backlight -Cadence -Average Cadence -Max Cadence -Low Battery Indication
