> Well, it may be for you. I've been biking for 15 years and it really is an issue for me. I don't want pedestrians, cars or fast objects on bike lane. If there are a lot of bikes on the bike lane and convoy goes at 30 kph that's perfectly fine, I go 30 too. But if people go 25 and some asshole is trying to go at 35, then we have a problem.

Speed differentials like that are the norm where I bike. Bikes mainly share a section of the road with pedestrians. So you get people standing around, going 0kph; you have people walking 5kph; people jogging 10kph; kids, the elderly, and people loaded with groceries biking 15kph; normal cyclists who aren't in a hurry doing 20-25kph; fit cyclists and people in a hurry up to 35-40kph. I don't think anyone's got a problem with it really. We kinda know how to share the road, even with people going different speeds.

Drivers, mainly, are afraid of fast cyclists jumping red lights.

I, as a cyclist, am more concerned about dogs, but that phenomenon hasn't bothered me much in the recent years. I once got bitten by a dog that gets excited by cyclists..

Seriously people doing 40kph in a city street? The average for a Tour de France pack was somewhere between 26-29mph ~= 41-47kph. That's assuming no stop signs , obstacles and plenty of the pack grabbing a wheel.

I think you're over-estimating average possible speed on a city route.

The speeds I listed were not averages, but instantaneous; the purpose were to outline the speed difference between different moving things that share the path.

Yes, more or less any grownup in fair shape can pedal 40 kph on a flat, as long as they don't run out of gears. Maintaining over 40 kph average (which means going much faster at times) for the duration of a long race is a completely different thing.

And yes, some people actually like to sprint like hell for fun. Sometimes I do too.

Think about it for a moment. Club cyclists often aim to average around 27 kph for something like a 80 kilometer trip. Hitting 40 on a nice flat or downhill section on your commute of 3 km is nothing.

I think we'll have to disagree about what the 25kph limit means. It allows untrained, unprepared, possibly drunk folks to man a vehicle which does all the work for them at that speed.

You prefer freedom for the avid electric cyclist, I want safety for pedestrians and slower cyclists.

Why are cycles held to a higher standard than cars in that regard? People drive without licenses, and they DUI, and they drive without appropriate training, and they text and drive, and they kill people. We still don't limit the whole class of vehicles to a maximum speed that won't kill.

This whole thing is so backwards. These limitations just reward people who take the big metal box, and punish those who would prefer a combination of muscle power and some electric aid.

Also, I think you're seriously overestimating the amount of danger 250W can do. I still hold that it's very unlikely for a drunk cyclist to do any significant damage to anyone except themselves with that much power, speed limits or not.

Aren't you focusing the potential negatives a little too much here? Allow a few bad apples to ruin the whole thing? If cars were invented today, you wouldn't let them on the road.

Vehicular traffic is all about taking a controlled risk for convenience. I think we could take the risk of removing the speed cap on low power bicycle motors and we wouldn't see a massive surge in pedestrian/cyclist injuries or deaths or accidents in general. Even in the hands of a drunk idiot, the bike is still far less dangerous than a car, and easier to evade should it come to that.

My daily commute (when I rode a bike) was much shorter than a Tour de France stage. You have to consider that that's the average over more than 20 consecutive day-long legs.

I think you are underestimating the difference between maintaining an average speed during a whole day and maintaining that same speed for 20 minutes.
