|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. The watts reading is based on a mathematical relationship between power and speed. This formula, along with our proprietary software accurately estimates the cumulative effect of 16 interactive forces. Features are speed (current, max, average, comparison, percentage of max), distance (countdown, percentage to arrival, trip 1, trip 2, odometer 1, odometer 2, odometer 1+2), time (stopwatch, ride 1, ride 2, time to arrival, time of day), calorie expenditure, power (current, max, average), temperature (current, high, low, C/F), cadence (current, max, average), automatic functions (start, sleep, lap), heart rate (current, max, average, upper/lower limit with visible alarm), altimeter (current, gain/loss, percentage gradient, home altitude storage), 2 wheel sizes, service interval reminder, backlight and low battery indicator. Comes with all mounting hardware.
