They need a distinction between pedal assist and fully electric (motor) bike.
I live in Luxembourg and the infrastructure is not as good as the Netherlands. Majority of offenders (in my experience) are delivery guys and teenagers. Where teenagers simply don't care & do reckless things like passing on a big intersection at full speed on a red light, delivery guys do the same things for extra tips.
Some of the fat-tire electric bikes are really fast, I happen to chase them on Kirchberg cycle road. I sustained 40km/h average behind delivery guys and they were still faster, eventually dropping me. (I was on a road bike).
Simply put, anything above 250watts does not belong to cycle lane.Includes humans :j
> need a distinction between pedal assist and fully electric (motor) bike
The only meaningful difference is if there is a motor or not. If there is a motor, it gets a speedometer and you have to stop at stop signs and red lights and follow speed limits. If you are powering yourself, it’s a bit more understandable that you don’t want to stop and start at every intersection. (Though if you have a racing bike, I’d reattach the speedometer and speed-limit requirements.)
Teenagers do dangerous things on normal bicycles too. The nearest I have ever come to an accident with a bicycle while driving (in the UK) was a teenager shooting out at high speed across the road from behind a parked van. Having cyclists sharing space with pedestrians is made worse by ebikes (which are effectively mopeds or motorbikes) but is a real problem with pedal bikes too in some places.
A pedal-assist e-bike with a 500 Watt motor and an easily bypassed speed governor looks like a bicycle, it is pedaled like a bicycle, and yet it is unsuitable for a bicycle lane or a path shared with pedestrians.
Pedal-assist feels to me like a complete red herring to the actual issues. It's often an arbitrary line but it doesn't make much difference to safety at all. (nor, IMO, do power limits, because it either limits cargo bikes or makes lighter bikes a lot less predictable: I would think an acceleration limit would be a more sensible option).
(build-in speed limits that are significantly below what the average cyclist can achieve by pedaling also seem kind of silly. IMO people might not bypass such limits as much if the limit was put at a more sensible level)
They are popular for cargo bikes; picture a parent with a couple of kids, or a big grocery run. They are also a great way of commuting without having to worry about being sweaty when you arrive, if you have a long commute. Lastly, they are great for people who are getting back in shape or starting to suffer the effects of aging. They are great all around.
The point of pedal-assisted e-bicycles is to assist pedalling and they are hugely popular. Around 30% of bikes I met on my ride today was them. It's a hilly ride with some slopes that are way too steep for recreational cyclists, older folks and children; this way they too can enjoy nature further away from the city.
Not necessarily against the idea but 20kph is very slow. It would be super easy to accidentally go over the limit unless you have a cycling computer attached to the bike and constantly monitor your speed.
Cars are heavier, have longer stopping distances, poorer visibility and have speed measuring equipment installed.
20kph is not a difficult speed for an adult on a push bike on a flat surface, so we’re not just talking about ebikes where a mandatory speedometer could make sense
The issue should really be about kinetic energy and the likelihood of collisions.
With cycles (including e-bikes), the rider is exposed and is likely to get hurt during a collision and this provides a feedback loop so that experienced riders are likely to take care and be very attentive. Cars don't have this feedback loop and are also orders of magnitude heavier, so it's really a different situation.
It's bizarre to require a slower speed limit for a much lighter vehicle, when logic dictates that cars should have the much slower speed limit.
> We should congratulate cyclist on becoming fully fledged (oppressed) road users.
Belgian view here. Flanders is slowly getting the Dutch cycling culture. E-bikes are forbidden from assisting above 25 km/h. You can go faster, but you will be providing the power yourself.
Something changed on the biking paths when e-bikes became the norm. Average speed went from 15 km/h to 25 km/h. This, combined with the heavyer weight of these bikes, created new dangers. A big ebike bike hitting a pedestrian routinely throws the pedestrian in the hospital and with life long damage. The fat bikes, some esteps and the food delivery people are worse. They tend to drive asocial, and are commonly illegally modified for higher speeds. The law is behind, and stupid politicians make it worse by stopping the police checking the bikes.
Meanwhile, bike paths are a lot busier, and if near pedestrians, things are getting dangerous by default. I've decided for myself to limit my speed to 20 km/h in the city centers or at schools, and commonly go even lower. 25 is only for the ebike 'highways' next to secondary roads.
I am pro stricter regulation and follow-up for my ebike. Belgium famously only implemented laws against drunk driving after an idiot killed a whole class at once. Let's not wait for an ebike equivalent. Better to do this calmly and thoughtfully now.
Yes electric vehicles completely changed the dynamics on bike lanes and pedestrian sidewalks (they drive on sidewalks in many European cities!). The kinetic energy is order of magnitude larger.
10-15 years ago police was stopping me and telling to get off the bicycle while I was driving bicycle carefully 4-5kmh on a pedestrian sidewalk in some major European cities. Now we have >15kg vehicles manoeuvring at >20kmh between pedestrians. The more east and south of Europe, the worse it is.
I find it mind blowing that ~42% of all cycling deaths are men aged 70+.
It obviously confounds fragility with participation but, still, it must mean that people continue to use bikes -- I'm guessing increasingly e-bikes -- well into their old age.
I think that if you as 60+ person cannot bike without support your brain is probably also not fit enough anymore for the speed you are going to ride at. So, I advice older people not to use an e-bike. I am not going to use one. Maybe a trike is a safe option at speeds not exceeding 10km/h.
I wonder how many of those are just heart attacks triggered by the exertion. A member of my family died that way (though they were not that old, and were relatively fit)
As the article says: this is not a general speed limit but an experimental speed limit for an apparently very crowded area where many kids cycle to school.
As someone whose 'normal biking speed' ist typically 30+ km/h on suitable bike lanes, I have no problems with speed limits at critical choke points.
Ah, this bit of crucial context seems to be missing from the entire rest of the discussion. Also makes what otherwise sounds like an uncharacteristically bike-hostile move actually seem fairly reasonable.
Tho tbf one still hopes that they come up with an infrastructure solution that makes it unnecessary in the long run.
I'm not sure whether the Guardian article mentioned this or another one I read: the road segment in question seems to be in the old town which makes it difficult to find an architectural solution.
12 mph is an odd speed to choose given legal e-bikes in Europe are limited to 15.5 mph for electrical assist. Might as well either make it 15.5 mph if the road is open or say something like 5 mph if it's a pedestrian zone.
By the way with 5 mph you wouldn't enforce it accurately as there are no speedos or speed cameras for bikes but it makes it clear if you are going 15 mph you are breaking it. That's what the have for the shared walk in Regent's Park for example.
> “This is all about cyclists on motorised bicycles, so I should think you would do something about motorised cyclists. Make a rule for them and not for all cyclists.”
There's a certain sub strain of cyclists that want absolutely no rules for them.
In a just world, cyclists would have more freedom than cars, but pedestrians would have most of all. But walking through European cities with large cycling cultures can be dangerous, too, especially for children and the elderly. Too often, cyclists will completely ignore stop signs and stop lights, or go at full speed on the sidewalks.
And because I know someone is going to retort that car drivers break traffic laws, too: drivers acting dangerously shouldn't excuse cyclists.
What that woman you quoted said definitely resonates with me. I cycle a lot and the rise of e-bikes has definitely made my experience worse. Those bikes are capable of inficting a lot more damage yet I find that the average skill level of e-bike riders tends to be lower than that of the general cycling population. IMO not a great combination.
I don't like to think of it in terms of freedom. Everyone has the same freedom to use public highways. The difference is responsibility. If you decide to use a bicycle you have a bit more responsibility than if you walk because they can go faster. If you decide to use a motor vehicle then it should come with a huge amount of extra responsibility. Ultimately you have the added responsibility of ensuring the safety and freedoms of those more vulnerable road users. So it's not "less freedom", it's "greater responsibility".
The problem is that there are effective mechanisms for punishing irresponsible drivers (and motor cyclists), but none (at least here in the UK) for punishing irresponsible cyclists.
The other problem is that cyclists often share space with pedestrians. I see cyclists on the pavement all the time (mostly illegally - and without consequences), I never see a car driving on the pavement (some park on the pavement, which is annoying).
Proper separate infrastructure (i.e. not just painting a dividing line on the pavement as happens around here) is expensive and requires a lot of space. It is not always practicable, and even where it is the money would often be better spend elsewhere - e.g. on public transport.
Most fatbikes have a much more powerful motor than a regular e-bike, and can be used without pedaling at all. They are listed as 250W, but it's actually a software-limited 750W motor. Local vendors provide unlock instructions along with the bike.
It's just a motorcycle in disguise. Then, to make matters worse, they weigh 30-40KG + two 12-year-olds on top - that, combined with reckless riding, can do a lot more damage than a boring cycling incident.
I mean ordinary as non-electric. I know what an electric fatbike can do of course. The article makes it ambiguous as it's talking about the common limit for all cyclists.
These are undrivable as a city commute, not to mention the stealing risk as they're usually expensive. I knew some people who attempted and gave up after few weeks.
People drive fatbikes from solely selfish reasons. They want something heavier and larger than others, they want others to give way and be afraid of collision.
Nah, its almost for sure xenophobic and classist. I think fat bikes are the best thing that happened to amsterdam because all the scooters disappeared. All the poor people that used to ride scooters are now riding fat bikes. Its better for their health and their wallet. Yes they tend to be a bit less educated and socialised, but they were like that when they drove scooters as well. Banning fat bikes is gesture politics.
Your suggestion would completely kill e-bikes, I don't think that is a good idea. Above a certain speed limit they should need to ride on the regular road though.
On a regular e-bike you don't get up to 25km/h without putting in the effort. If their mental capacities are that far gone, they won't be able to go that fast anyway. They'll top out at 20km/h or something.
12mph seems very slow, but I suppose you can still cycle in the carriageway if you're a decent cyclist?
Really we need to ban motorised vehicles that go above 12mph. They are not bicycles and should not be in cycleways. I feel there is a big difference between someone who is able to pedal at higher speeds and someone who is just using a motor vehicle.
I cycle at 14mph average on a normal pedal bicycle.. they can fuck right off the with this. We are not all fat fucks on electric scooters pretending to be bicycles
Cycling culture and infrastructure in Dutch cities is unique. Shame that it's wrecked by assholes who want something bigger and faster, or drive outright electric motorbikes.
The question is, would I be allowed to use the road instead, if I go anywhere between 45kph to 60kph, as I tend to do on road-/gravelbikes on flat grounds, without too much head wind?
Thinking about it I even do 45kph with an old 3-speed rear hub and coaster brake, mudguards, dynamo, porter, basket, from 1985 when in Hamburg.
This makes no sense for me. Maybe don't declare bike lanes as such, if they are unfit for the purpose?
I life on a big street intersection with traffic lights in a city. Every year I can observe at least one cyclist crash with a car. Mostly because they just ignore the traffic lights completely.
As cyclist you learn that traffic rules are not for you, because when you ignore them, normally nothing happens. When you want to safe lives, you need to register bikes and punish cyclists that ignore traffic rules. Otherwise the physics will do it, with much harder punishment.
In most countries people use bicycles as some form of leisure travel but Dutch cycling is a need for speed!

The boundary between a bicycle and a motorbike has completely dissapeared.
That boundary needs to be recovered, and then rules will make sense again, until then, any effort is futile.
> The boundary between a bicycle and a motorbike has completely dissapeared.
Not really. The first motorbikes were bicycles with engines attached. Many current electric motorcycles are bicycles with electric motors attached.
If it has a throttle and does not require pedal assist, it is a motorcycle.
A pedal-assist e-bike with a 500 Watt motor and an easily bypassed speed governor looks like a bicycle, it is pedaled like a bicycle, and yet it is unsuitable for a bicycle lane or a path shared with pedestrians.

What's even the point of pedal-assisted bicycles, other than gaming the system and exploiting some legal quirks?
Neither they are fast, powerful, or have reasonable range, yet are already too heavy to pedal only.
They are popular for cargo bikes; picture a parent with a couple of kids, or a big grocery run. They are also a great way of commuting without having to worry about being sweaty when you arrive, if you have a long commute. Lastly, they are great for people who are getting back in shape or starting to suffer the effects of aging. They are great all around.

They work well for people who have limited mobility; think in terms of people who would otherwise be able to cycle but would tire easily, for example.
They're apparently pretty good for cargo bikes where you can pull a heavy load much more easily.
I personally don't like 'em because I can get to 15.5mph very quickly and then it's like running into a wall because they're so heavy.
I think it's pretty clear what is a bicycle. Bicycles don't have engines.
Do you? At least the german law not. Looks like the law in the nederlands too.
German law is created for litigation not for clarification.
You talk about the civil law.
Not necessarily against the idea but 20kph is very slow. It would be super easy to accidentally go over the limit unless you have a cycling computer attached to the bike and constantly monitor your speed.
The exact same argument can be made for cars.
Doesn't stop the government wasting half my Saturday and stealing £100 every couple of years.

The solution to this is better cycling infrastructure to separate them, not making cycling less useful by setting ridiculously low speed limits.

There is zero phobia involved, just facts. I imagine you count second generation immigrants as Dutch assholes ?
