The speed of a bicyclist is dependent upon several factors, including the age and physical condition of the user, the type and condition of the user’s equipment, the purpose and length of the trip, the condition, location, and grade of the bikeway, the prevailing wind speed and direction, and the number and types of other users on the facility. Although some adults may be able to maintain faster speeds (e.g., 25 to 30 mph) on level grades and attain speeds higher than 35 mph on steep descents, typical adult bicyclists average 8 to 12 mph on flat terrain, and steep inclines may result in speeds comparable to walking (2 to 3 mph). Research has found a median cruising speed for urban bicyclists as 9.7 mph with a 15th percentile speed of 8.2 mph. The 15th percentile speed should be used to inform bicycle crossing speeds at intersections as it represents the lowest range of bicyclist operating speeds.

For this reason, there is no single design speed that is recommended for all bikeways. Design speed considerations for bikeways are incorporated into specific bikeway guidance throughout as appropriate.
