These are inverted speed bumps targeting mopeds/scooters, and recently, fatbikes. They're fine to cross if your speed is < 25km/h and/or you have little suspension. So for most cyclist it's alright.
In this case I'd choose the inverted speed bumps over the desirepath.
Because it's trivially easy to override the 25kmh limit so these can and will speed along through narrow streets which are often pedestrian-only, and are operated by literal kids (I have seen 10 year olds ride these - without helmet) whose risk assessment is still lacking. Although that lack of risk assessment isn't limited to the kids driving these things.
A combination of these factors makes that they're a danger to not just anyone around a fatbike, but also the drivers themselves.
Fatbikes are not able to be insured, so if there's an accident, the driver (or the parents, if it's a kid) will have to pay for damages themselves. There was actually a court case about this recently which ruled that the father of the kid will have to pay. Rightfully so.
If we compare this to normal bikes, as was a part of your question, those are smaller, lighter, and slower than fatbikes, which makes them much safer for people around them and the people using them.
Legally, yes, fatbikes have been ruled as e-bikes, hence why they have a 25 kph speed limit.
However, because this speed limit is so trivially easy to override, I do not agree with this definition. They should be classed as something like scooters instead.
Fatbikes are not just bicycles with extra fat tyres, they have a powerful electrical engine which allows them to reach speeds far in excess of that 25pkh limit. They have no business in busy city centres where they are far too big to have a space in the street scape.
Oh interesting because a fat bike means to me as an American just a regular bicycle with 4 inch wide tires or wider but it could also refer to an fat tire e-bike as well I guess
I guess that's valid, but non-electric fat bikes never became popular in the Netherlands. There's a few, but it's quite rare. Also language wise, didn't have a special name in Dutch. but with the spike in popularity of these bikes, but electric, the English name Fatbike stuck.
Fatbikes in the Netherlands refers specifically to a type of electric bike with a more like motorbike/scooter shaped frame. This type has taken over the term because due to a lot of cheap bikes in this style flooding the market from like temu n the like, they've become really common on our streets.
So yes when a Dutch person mentions a fatbike, they specifically mean an ebike.
Controversial take, but: fatbikes are cheap ebikes, so you get younger and less wealthy people riding them. They're really not that big of a problem and seem more like a socially accepted way of hating on a group of people.
I did deliveroo for years. Next thing is putting expensive metal racks at the dirt path. It's pathetically annoying.
I broke my shoulder once cycling somewhere in the dark, where all cyclists went for years, at rhijnspoorplein, because they suddenly decided to put tree trunks on the ground exactly where people used to ride. I fucking hate Amsterdam.
You can just about see the drainage covers installed in the curb in each valley(?). The road is probably also slightly angled inwards towards that curb to further help drainage.
Yeah I love the Netherlands but i really don't get why they have put one here

I expected fatbikes to be a condescending dutch name for mobility scooters lol
If only they were, then they'd be less of a menace
Y r fatbikes specifically a menace compared to other bikes?

I'm confused, is this assuming that fatbikes are all also e-bikes?
Fatbikes are just bicycles with extra big tires.

Ahhah got ya makes sense

It could be a slur for cars
you'd choose the speed bumps on a dry weather, but when they transform into a pond you would slowly go around them like everyone else
There is drainage.
Never seen any standing water in them.
In those circumstances this desirepath would be quite slippery.
This makes sense, thank you for the explanation :)
I actually find them rather fun to ride over on my regular eBike.
At the right speed they're a nice break from the smooth cyclepaths :P Shortest pump track.
Probably a 30km/h zone and cyclists who can drive faster generally don’t follow the speed limit
cyclists who go past 30km/h don't take this cycle path
School zone

Along Nadezjda Mandelstamstraat, Amsterdam, Netherlands. No unusual context here, aside from being in a school zone next to a park.
An article on this sort of bike path traffic calming feature, intended to slow mopeds and scooter; surprisingly the only result talking about it this particular type: https://www.aviewfromthecyclepath.com/2011/11/speedbumps-on-cycle-path.html

I am a rollerblader, I would love this!!
First time a desire path is a bad thing and should be corrected.
Dunno. Still makes people slow down. Looks a bit ugly ig?
Doesn't look like there needs to be a speed limit there. A straight path with good visibility far ahead.
Does this path have a gruesome history?
Oh boy, you need speed limit if you are on a moped or fatbike...
School zone
Bijlmer spotted!
I can imagine rain water collects there - and freezes in the winter.
In the Netherlands?
Unlikely. We tend to remember that (it probably rained while installing it) and take care of drainage.
There is drainage
That's more engineering and thought than I'm used to.
You can just about see the drainage covers installed in the curb in each valley(?). The road is probably also slightly angled inwards towards that curb to further help drainage.
There's a drain visible in the photo
That design would scrape the bottom of my escooter, desire path it is!
Damn speed walkers nearly rear ended my pet tortoise!
The absolute limit of these is 41km/h before you start flying on a 95kg 2 wheeled vehicle
Speed is always the desire
🤣
Speed divot.
I'd assume it was sinking and not on purpose so id avoid it
