He's also not out of the norm in any way. Maybe most riders won't average that speed (although I'd suspect on flat ground they easily would), but any rider going down a decent hill will easily hit 40+ kph.

The average running speed of humans is around the same limit - 11 to 15 mph (17 to 25 kph). Almost everyone bikes faster than that.



Yes, he is out of the norm. Very few people ever ride 90km on a touring bike. Many bicycle enthusiasts do but they are in the minority of people at large.

I’m not sure what point you’re making about the downhill speed? If you dropped a cyclist out of a plane, they’d do like 320kph. Nobody needs on an electric assist when they’re going downhill at 40kph.

Also I’m not sure who you think is averaging a running speed of 15mph for more than a few hundred feet. If you can hold that speed for 4 minutes you’d be one of about 1000 people in the history of the world. Even holding 11 mph for more than 10 minutes is out of the realm of possibility for the vast majority of people.

Electric bikes at reasonable speeds help people of average to below average fitness (whether by age, disability, or other reason) get out and be active on a bicycle. I don’t believe they should be souped up to help some MAMIL (middle age man in lycra) set a new Strava segment record.

I cycle as my primary means of transportation, on a flat-bar touring bike in normal clothes. I average about 12mph. I'm faster than most other cyclists I meet on the road. The only cyclists faster than me are on road bikes and wearing specialist cycling clothing (I estimate about 20% of cyclists where I live).

I could go faster, but then I'd have to change clothes and shower, which would make me slower overall.


GP is responding to the ridiculous assertion that the average RUNNING speed for humans is 11-15 mph.

Even taking into account only young adults, I'm sure most of them can't sprint 11 mph


Counterpoint is if you do 40 mile rides you are most likely already an above average cyclist.

Almost no-one cycles faster than that. If you cycle at 25km/h in Copenhagen, you will be in at least the top 5% for speed. I used an electric bike for a while, and could overtake almost everyone — I assume it followed the same EU regulation limiting it to 25km/h.

I think I'm a fair bit faster than average, and I tend to cycle at about 15-18km/h, at least according to two GPS tracks I have. (I don't log how fast I'm cycling; I forgot to turn it off on those two days.)


Copenhagen has a different cycling culture to other places. Where I live more people commute on road (racing) bikes and will shower when they arrive at work. This is because it is very hot in summer and you can't avoid getting sweaty, while in winter it is often raining and you get covered in sand that is caught in the road spray.

Many of the cycle commuters in my city also join group rides (peletons) on the weekends. So it is very common to have cycle commuters riding above 30km/hr on both shared paths (pedestrians, cyclists, scooters, dogs etc) and on the roads.

Electric assist bikes are becoming more common here, as they allow people to commute without needing to shower in summer. Legally they are restricted to a 250W motor and are also supposed to lose electric assist above 25km/hr. I routinely pass people riding these bikes when doing a training ride.

There are also quite a few people importing e-bikes and motor kits that have much more powerful motors and no speed restrictions enabled. When I am riding hard (40+ km/hr, >300W depending on wind direction) on an aero-road bike and get passed by a guy sitting upright on a mountain bike who is barely pedaling - his bike has to have a 500W or higher motor.

I would like to see the current regulations we have retained riding on shared paths, but I would also like to see the unrestricted electric bikes added as a new class for road use. A e-bike with a 500-1000W motor is easily faster than most cyclists. With modern disk brakes, stopping at speed and in the wet is less of a problem (c.f. rim brakes). The battery required also makes it easy to mandate powerful LED headlights and tail lights. Adding indicators wouldn't be hard either.

If you said, "the average running speed for trained male high school seniors is 10 mph", I might find that plausible. Probably high, but plausible.

1. Men are substantially faster than women. The number you gave is high for men, but ludicrous for women.

2. There is nothing average about a 15 mph (4 min mile) running speed. It is quite rare for men to achieve this speed and has literally never been accomplished by a women.

3. Those numbers reflect an unloaded run of exactly 1 mile. Commuting in the city by running would substantially slow people down.


> The average running speed of humans is around the same limit - 11 to 15 mph (17 to 25 kph).

The physical fitness requirements for the US Army assigns maximum score to a 6.5 minute mile (over two miles) and that's for 17 year old males. For late 20s women, the minimum qualifying time is about a 10 minute mile.

The world record for the fastest mile run is 3:43.13 for men and 4:12.56 for women. Literally no woman in history has managed to maintain a 15mph speed for an entire mile. Even men only hit that point in the 1950s. Going for a 10k run, the world record is a touch over 14mph for men and somewhat less than 13mph for women. 15mph isn't "average running speed"; it is "world-record speeds."

11-15mph might be reasonable (but definitely on the higher end) for average sprinting speed (we're talking <100m). For running speed, 8-9mph is more reasonable for expectations of fit young males (you need about 8.5mph to qualify for the Boston Marathon if you're a young man, just 7.3mph if you're female).
