Riding a bicycle is an excellent form of exercise. However, fitness trackers and smartwatches are designed to specifically detect the characteristic motion of walking or running, a movement pattern that cycling fundamentally lacks. This disconnect causes confusion for many users who want their cycling activity fully represented in their daily movement goals. The issue lies in how these devices sense movement versus the actual physiological effort delivered during a ride.
How Step Trackers Define Movement
Consumer fitness trackers use a miniature component called a tri-axis accelerometer to measure movement. This sensor detects acceleration in three dimensions—forward/backward, side-to-side, and up/down—multiple times per second. The device’s internal algorithm then analyzes this raw data to identify the distinct signature of a step.
A true step is characterized by a specific pattern of vertical displacement, impact, and the rhythmic swing of the arm or leg. When cycling, the body remains relatively stable, and there is no repetitive foot impact against the ground. Since the motion is a continuous, circular pedaling action, the accelerometer often fails to register the activity as a step, leading to an artificially low count.
Metrics for Measuring Cycling Activity
Quantifying cycling effort requires shifting focus to metrics that accurately reflect the physiological workload. The most effective way to measure the intensity of a ride is through Metabolic Equivalent of Task, or METs. One MET represents the energy expenditure of sitting at rest, and all other activities are measured as a multiple of this value.
The MET value directly relates to the rate at which the body consumes oxygen and burns calories during the activity. For example, bicycling at a moderate pace of 12 to 14 miles per hour is assigned a MET value of 8.0. This means the activity expends eight times the energy compared to rest. Common metrics like distance traveled, duration, speed, and average heart rate are also tracked to provide a comprehensive view of performance.
Calculating Step Equivalents for Cycling
To bridge the gap between cycling effort and a daily step goal, a practical conversion is often needed. This conversion relies on translating the metabolic effort (METs or calories burned) into an equivalent number of steps. A common approximation used in conversion charts is based on the idea that 2,000 steps roughly equals one mile of walking.
Using standardized charts, cycling at a leisurely pace of 10 miles per hour might equate to approximately 93 steps per minute. A more vigorous pace of 15 miles per hour could be around 160 steps per minute. These figures are estimates that allow users to manually log the effort in the familiar language of steps, even though the movement was entirely different.
Ensuring Accurate Activity Logging
To ensure cycling is accurately recorded and contributes to overall fitness goals, utilize the dedicated features on your device. Nearly all smartwatches and fitness trackers include a specific “Cycling” or “Outdoor Cycle” workout mode. Activating this mode tells the device to disregard the step-counting algorithm and instead focus on collecting cycling-specific data.
When in cycling mode, the device focuses on metrics like GPS data for distance and speed. It also uses heart rate for a more accurate calorie burn calculation. Some trackers can pair with external sensors, such as power meters or speed/cadence sensors, which provide direct data on effort. If the device fails to track a ride, manually logging the duration, distance, and perceived effort into the companion app is the most reliable way to ensure the activity is counted.
