There isn't a direct conversion between miles on a bike and miles walked because the distance covered can vary based on several factors such as terrain, speed, effort level, and individual differences.
When cycling, the distance covered depends on various factors such as the speed, intensity of pedaling, and terrain. A casual cyclist can typically cover a distance of 10-12 miles per hour. Assuming a cycling speed of 10 miles per hour, it would take about 6-7 minutes to cover 1 mile.
Please note that these are rough estimates and individual results may vary. Additionally, it's important to consider that cycling can provide a more efficient means of covering distance compared to walking due to the mechanical advantage of a bicycle.
