"Bicycle exercise" or "cycpng" are common ways to describe the sport or activity of riding a bicycle for exercise or recreation. You can also say "biking" for short. Here are a few examples of sentences using these terms:
"I love going for long rides on my bike as a form of exercise."
"Cycpng is a great way to get a low-impact cardiovascular workout."
"My favorite way to stay active is by going on bike rides on the weekends."
If you want to talk specifically about competitive cycpng or participating in organized cycpng events, you can use the term "road cycpng" or "mountain biking." For example:
"I'm training for a road cycpng race next month."
"Mountain biking is a lot of fun, but it can be quite challenging on rough terrain."
I hope this helps! Let me know if you have any other questions.
