> Further to that, it generally feels as though the UK is a country massively in decline To a large extent it is a self-fulfilling prophecy. People expect decline so it happens. It has been happening for a long time - back to the 1960s or so when the UK became the only only country ever (still true) to have a space launch capability and lose it. That said, IMO the causes of this are widespread across the west. It is…

There is even more than that.

The west (admittedly this not only a flaw of the west) tends to think its cultural norms, identities and values are human universals.

There is also a tendency to think that the golden age of peace and prosperity the west enjoyed after the end of the cold war is the rather than the exception - it even lead to silly ideas like "the end of history".

With The Right Stuff though: LandCruiser 'Mudcrab' driven 7km under water across Darwin Harbour A rag-tag team of engineers, commercial divers and rev-heads have successfully driven a waterproof electric vehicle 7 kilometres under water across Darwin Harbour, in a stunt they claim has broken two world records. https://news.ycombinator.com/item?id=36928038

it's not surprising to me that the bosch mid-drives are failing, they're typically placed at an angle that catches all the run off from every tube at the lowest point on the bike (except on recumbents), and the controller is (usually) integrated. mid-drives are great, the gear advantage rocks; the bosch units suck but unfortunately they had so much industry sway that a lot of ebike frames are coming out built around…

The gear advantage of a mid-drive rocks but I was quite surprised that I chewed through a rear cassette in under a year / about 1k miles -- a 250W motor + heavy cargo bike + kid passenger + a large and pretty strong rider exert an awful lot of force. And with the assist, I almost never use the larger cogs, so all the wear gets concentrated. (This compares to many, many thousand miles on my road bike.)

Still love the thing, though.

As a biker, cyclist, skater, and ebiker, I’ve settled about various wax-like sprays to keep crap off and out. ACF-50 for the motorbike, various protective wax sprays for the bicycles, Vaseline for skate bearings.

Any brands for the bike sprays?

Sure, the one I use right now is a German spray: https://www.weicon.de/en/corro-protection-wax-like-corrosion...

YMMV

The bike brand doesn't really matter, the brand of the electrical motor system matters. There are 3 big leaders: Bosch and Shimano on the high end, Bafang on the low end with Brose, Yamaha and a handful of other smaller brands occupying a much smaller fraction of the market. Bosch is also widely used in the Netherlands.

It does matter since different brands may offer different levels of weather protection. Typically only Dutch bicycle makers care about things like proper mudguards and chain guards, for example. And some, like Azor go crazy and test their parts in a rust chamber. And, for example, the Cube bicycle as depicted in the article, is clearly not designed to be used in rainy weather. Who knows what else shortcuts they took?

> Typically only Dutch bicycle makers care about things like proper mudguards and chain guards, for example.

That is not true.

It is about class of bikes, not brands. Sure there are brands such as Gazelle who focus pretty much on those characteristics only but there are other brands doing the same all over the world alongside more racy models.

The bike depicted is a mountain bike, so no it hasn't be designed with fender in mind but that doesn't mean Cube or any other non-dutch brand doesn't produce city/trekking/touring bikes.

Having said that, I would expect a mountain bike to be built to survive wet and muddy conditions.

I’ve been doing a bit of (non e-bike) riding in poor weather of late, and it’s really surprising just how wet and dirty everything gets. After a wet road ride, every surface is covered in black, greasy dirt. It rots fabric, makes grinding paste in mechanical parts and generally makes everything worse. You need really good seals to keep that crap out.

Do you have full mudguards/fenders?

No, and this would help. While it’s commuting, I’m taking a route 3-4x longer than I need and picking off PRs. The fender helped a little, but was also finicky and I didn’t get a lot of value from it.

Your point is correct - some better gear would help.

Use mudguards, chain guard and coat guards.

Any recommendations? I had guards and found they rattled, slowed me and were less effective than what I wanted.

This is one reason I wish belt drives where more common.

The Netherlands does have a reputation for the best built/maintained roads in Europe. Maybe better drainage, fewer puddles and potholes? Plus flatter terrain, so less overall strain on the motor.

This. Road condition is the key. Most of the water you collect while riding, even with full length fenders, is dirty water sprayed by your and other users tires. The rain itself usually account for very little in comparison.

The article mentions "mountain bikes" several times, which implies the failing bikes aren't ridden on roads at all. The fenders shown on the picture are not the same ones to be used on the road. It's possible we're talking about two completely different types of cycling.

The guards aren't properly mounted (or perhaps lack sufficient rigidity & mounting points) if they are rattling and rubbing.

It's worth it to invest in good guards to keep the mud off your bike!
