The average speed of a bicycle is highly variable, but for a typical recreational cyclist on flat terrain, it generally falls between 12 and 15 miles per hour (19 to 24 kilometers per hour). This range represents the pace maintained for leisure or moderate exercise. The speed changes significantly based on numerous factors, including the bicycle’s design, the rider’s physical conditioning, and environmental conditions.
Average Speed by Bike Type
The type of bicycle used is a significant determinant of average speed, primarily due to differences in frame geometry, weight, and tire design. Road bikes are engineered for speed and efficiency, allowing trained riders to maintain averages between 15 and 20 miles per hour on smooth pavement. Their lightweight frames, dropped handlebars, and narrow, high-pressure tires minimize rolling resistance and air drag.
Hybrid or commuter bikes offer a balance between comfort and speed, resulting in an average speed typically ranging from 12 to 15 miles per hour. These models feature an upright riding position, which increases comfort but also increases aerodynamic drag. They use medium-width tires that provide better puncture resistance and stability than road tires, slightly increasing rolling resistance.
Mountain bikes, when ridden on paved surfaces, generally yield the lowest average speeds, often hovering between 10 and 12 miles per hour. Features that make them capable off-road, such as heavy frames and wide, knobby tires, work against efficiency on asphalt. These tires create substantial rolling resistance, and the upright seating position is inefficient for sustained speed.
Electric bikes (e-bikes) introduce a motor-assisted element. While the rider’s effort is reduced, the maximum assisted speed is often regulated by law, such as the 20 mph limit for Class 1 and 2 e-bikes in many parts of the United States. This assistance allows a less fit rider to easily maintain the upper end of the recreational speed range, often matching or exceeding the average speed of a conventional cyclist.
Average Speed by Rider Experience
The physical capacity and training consistency of the cyclist directly influence the sustained average speed. A beginner or casual rider, who cycles infrequently, typically maintains an average speed of 10 to 12 miles per hour. This pace reflects a lower level of cardiovascular fitness and endurance.
The recreational cyclist, who rides regularly, can comfortably sustain speeds between 12 and 15 miles per hour. This group has developed better aerobic capacity and can maintain a steady effort over longer periods, often completing rides of 15 to 30 miles.
Experienced and trained cyclists, who follow structured training plans, often achieve average speeds ranging from 16 to 20 miles per hour. These riders focus on increasing their power-to-weight ratio and improving their lactate threshold, allowing them to push harder for extended durations.
Professional or elite cyclists operate at a different level, often maintaining average speeds above 25 miles per hour during races. This performance is the result of years of specialized training, maximizing their VO2 max and efficiency.
External Factors That Change Speed
The environment and route conditions impose external forces that modify a cyclist’s average speed. Terrain is the most immediate factor, as gravity dramatically increases the effort required on an incline. A cyclist averaging 15 mph on a flat road might drop to 6 to 8 mph on a moderate 5% grade hill, though speed will spike higher on the descent.
Wind resistance is another external force, increasing exponentially with speed. Doubling the speed requires four times the power to overcome air drag. A strong headwind can reduce average speed by 2 to 4 miles per hour, forcing the cyclist to expend more energy. Conversely, a tailwind provides a substantial boost.
The riding environment dictates the flow and consistency of the ride. City commuting, characterized by frequent stops for traffic lights and intersections, results in a lower average speed, often below 10 miles per hour. Constant acceleration and deceleration in urban settings are inefficient and prevent the rider from maintaining a steady cadence.
Rides on open country roads or dedicated bike paths allow for a more consistent effort and higher sustained speed. Without the need to stop and restart, the cyclist can maintain momentum, leading to a higher overall average speed compared to an urban route.
How to Measure and Improve Your Speed
Measuring Speed
Tracking and quantifying speed requires reliable measurement tools that record distance and time. Cyclists commonly use dedicated bike computers attached to the handlebars, which receive data from wheel sensors or GPS satellites to provide real-time speed and distance metrics. Smartphone applications, such as Strava or Ride with GPS, utilize the phone’s internal GPS to log ride data for later analysis.
Improving Speed Through Equipment and Technique
Improving average speed involves systematic changes to both equipment and riding technique. Proper bike maintenance, particularly maintaining optimal tire pressure and keeping the drivetrain clean and lubricated, reduces mechanical friction and rolling resistance. A properly inflated tire significantly lowers the power required to maintain a given speed.
Adjusting the riding position to be more aerodynamic is a simple way to gain speed, as reducing the frontal area minimizes air resistance. Leaning forward and bending the elbows lowers the body profile, which saves power at speeds above 15 miles per hour. The most effective long-term strategy for increasing average speed is consistent riding, which builds cardiovascular and muscular endurance.
