If you look closely near the top of the front fly-wheel of your Peloton bike, you may notice a blinking red light. This is a completely normal light (even though we have all been trained that blinking red lights = bad!). This is simply the magnetic resistance sensor for the bike, which monitors & helps determine your output numbers. The Peloton’s resistance sensor, located over the top of the wheel, under the clear plastic cover, blinks red when it is working correctly.
