How to Convert Bike Miles to Steps? Here are the 4 Easy Methods
Four methods to convert your bike ride into steps so that you can participate in step challenges. A general rule of thumb is a moderate intensity biking for one hour is equivalent to 10,000 steps.

TL;DR
If you are looking for a quick conversion, then a moderate intensity biking for one hour is equivalent to 10,000 steps. You can skip the rest of the article. But if you are interested in more details, then stick around. We will look into multiple aspects of biking, walking, step counting, and various ways to convert biking into steps.
Why am I talking about this conversion?
I am participating in the WebMD Team Team Steps challenge with my colleagues. There are similar challenges from Fitbit and other organizations. In this challenge, your steps are compared with others, and a winner is announced every few days. This encourages everyone to do better.
Not everyone is a walker, though. I like biking, and riding my bicycle for two hours is an easier job for me than walking for one hour.
Unfortunately, Apple Watch, Fitbit, and other activity monitors do not capture corresponding steps for biking.
This is because activity monitors such as Apple Watch, Fitbit, Garmin, and Xiaomi Mi Band count steps based on arm movement. Your arm is mostly stationary while riding a bike.
There are many discussions in Apple and Fitbit forums regarding this issue. You can find similar conversations on other forums. All those discussions confirm that natively Apple Watch, Fitbit, and other activity monitors cannot record steps for your bike ride.
