Most cyclists want to know one thing: is my speed normal? The honest answer is that bike speed varies more than almost any other form of self-powered movement, because wind, terrain and bike type swamp fitness differences.
The short answer
A recreational cyclist on flat ground with a road bike typically averages 19 to 25 km/h (12 to 15 mph) over a ride of an hour or two. On a hybrid or city bike, subtract a few km/h. On a mountain bike off-road, subtract considerably more.
By rider level
- Casual / occasional : 15–19 km/h (9–12 mph)
- Regular recreational : 19–25 km/h (12–15 mph)
- Experienced / club rider : 25–32 km/h (15–20 mph)
- Racing : 32–40+ km/h (20–25+ mph)
These are sustained averages over a full ride, not top speeds. Almost anyone can hit 40 km/h briefly downhill; holding 32 km/h on the flat for an hour is a different matter entirely.
By bike type
The machine matters more than most riders expect, and almost all of the difference is aerodynamics and rolling resistance rather than weight:
- Road bike : fastest on tarmac : narrow tyres, low riding position
- Gravel bike : roughly 1–3 km/h slower on road than a road bike
- Hybrid / city : typically 3–5 km/h slower, upright position costs most of it
- Mountain bike on road : 5–8 km/h slower : knobbly tyres are working against you
- E-bike : usually 25 km/h assisted, because that is where most legal assistance cuts out
What actually slows you down
Wind is the dominant factor. Above roughly 15 km/h, most of your effort goes into pushing air rather than turning the wheels. A 20 km/h headwind can cost you 8 km/h off your average, which is why an out-and-back ride never averages out the way you expect : you spend far longer in the headwind section than in the tailwind one.
Elevation compounds. A route with 500 m of climbing over 40 km will cut several km/h off your average even if the descents feel fast. You cannot get the time back going down.
Stops count. If you are measuring average speed rather than moving average, every traffic light is in the number. On an urban ride, junctions can account for 20% of elapsed time.
Tyre pressure is the cheapest free speed there is. Under-inflated tyres can cost 1–2 km/h for no effort saving at all.
Average speed vs moving average
Bike computers usually show both, and riders often quote whichever is flattering. Average speed includes stopped time; moving average excludes it. On a café ride the two can differ by 5 km/h or more. When comparing rides, make sure you are comparing the same one.
Measuring it without a bike computer
Your phone already has GPS, which is the same technology a bike computer uses. Open the bike speed test before you set off, mount the phone on the bars or keep it in a jersey pocket, and it will show live speed, average, peak and distance.
For how this compares with dedicated hardware, we looked at it directly in GPS speed vs bike computer. The short version: GPS is comparable on open roads and less reliable under dense tree cover.
The takeaway
19–25 km/h is a normal recreational average on a road bike. Wind and elevation move that number more than fitness does on any given day, so compare your speed against your own rides on the same route in similar conditions. Everything else is noise.
