a beautiful foto collection from @Holzi from svizzerland…
I’ve never seen chains, but my brother would ride his bicycle year round and bought tires with metal studs (like Bicycle winter tyres - treads and studs explained | BikeGremlin US). He said they helped a lot.
One winter he had a problem. On some days his bicycle performed just fine. Other days, he’d be halfway to work and the hub wouldn’t engage. He finally took it apart but everything looked fine. He put it back together and things worked great…but only for a few days, then the same problem returned.
He eventually took it into the bicycle shop. It seems the grease used freezes when around -20° Fahrenheit (or about -29° Celsius).
The old Sturmey-Archer hubs took oil instead of grease. Makes real sense in cold weather.
The 4-5" wide “fat” bike tires are supposed to be good in snow. They are used a lot in sand. I don’t know if they come studded for the ice as well or not.

Can you see the carbon monoxide alarm to the left in picture?
Here’s something to think about Goran. All those rivets had to be put in close to white hot by a guy inside the tank and then he had to “buck them up” which means lock them in place while the guy on the outside formed the head. Talk about a hard way to make a living. Riveting gangs were gone by the time I started doing ironwork but it was a very skilled part of the trade. If you have ever seen video of erecting some sky scraper, it’s hard to believe. Some of those connections could have 20 or 30 rivets. I got into the trade 10 years after the Mackinac Bridge was built. That was the last riveted structure in Michigan that I’m aware of. Almost 5 million rivets and about one and three quarter million bolts.
Yes. Impressive craftmanship. Ear protection wasnt invented yet😀.
We need a clue, Göran. Personally I don’t even know what to look for 
Since you asked in that way I can probably see it but I can’t point at it because I don’t know either what to look for.
At first I was looking for a cage with a canary bird butI can’t find one…
Johan are spot on, look to the right of the white pipe far left, you could see the cage.
Poor bird, by the way.
And yes, the riveting work is impressive, hard to believe that kind of teamwork…
And check up “sprängnit” or exploding rivets, fun invention for when backside is out of reach.
Haha, completly missed that one. Same size and same vertical line as the hatch in the bottom my brain told me it was another hatch
I was more looking on that contraption on the far left side with the white pipe.
Easy to see once it’s pointed out, but I looked and looked and never spotted that bird. Makes me wonder about what else I have missed seeing that was in plain sight. Could have been the secret to an easy life. Definitely missed that one.
