The number of miles an average person can bike in an hour can vary widely depending on factors such as fitness level, terrain, weather conditions, and the type of bike being used. However, a reasonable estimate for an average person on a standard road bike would be around 12 to 16 miles per hour (mph).
It's essential to remember that this is just an estimate, and some individuals may bike faster or slower than this range. Professional cyclists or highly trained athletes may achieve higher speeds, while casual or beginner cyclists might go slower. Terrain with inclines, rough surfaces, or strong headwinds can also affect the biking speed.
For long-distance cycling events or races, the average speed can be significantly higher, often ranging from 20 to 25 mph or more for experienced cyclists.
