Just a reminder that on the bike & footh paths here in Oulu 🇫🇮, 2 cm of new snowfall must always be gone within 3 hours, on entire 166 km main 🚲🚶 network, 24/7. Maintenance needs to be fast, reliable & efficient, so that people can rely on it 👌 Join our Urbanism Masterclasses to learn more! 🤗

In addition to the 2 cm threshold, 4 cm accumulation of snow must never be reached, not even for a second, on the main network. The rest of the ~1000 km network of bicycle & foot paths in the city are naturally maintained at top priority as well 👌
Our next Masterclass is scheduled for 8-11 February 2026. There are still places left, so head on to www.masterclass.city and secure your spot 🤗

@pekkatahkola I assume this is just removing the depth, and cyclists still need tyres that can cope with the compacted snow underneath. How different are winter tyres from 'normal' or summer bicycle tyres?
Show threadJoonas SarajärviJan 10

@trantion @pekkatahkola When the snow is plowed well and the resulting surface is even, plain normal tires ("summer" tires as they sometimes are called) work most days just fine.

Studded bike winter tires are common here in winter and they allow paying less attention to the available grip, but e.g. I'm using the same tires year round in Oulu.

Show threadJoonas SarajärviJan 11

@trantion @pekkatahkola one potential problem with the snowpack layer is that if the weather warms up rapidly, the layer partially melts and then you have basically water on top of ice-ish material. That's really slippery and if it gets bad enough, it's close to unrideable with basic city bike tires.

With studded tires there's no problem at all. But usually we get only a small number of days with these conditions, so instead of switching tires, it can make sense eg. to just walk on those days.

@trantion @pekkatahkola

Winter tires should also be made of a different rubber-mix than the summer tires. Not like schwalbe that seems to use the same mix for both. The winter mix should be softer in low temperatures, the summer ones usually becomes stone hard and pretty useless on ice with no grip whatsoever. I'm using Nokian studed tires in Umeå. We don't have as well plowed roads as Oulu so we need better tires 🙂

The alternative solution would be two wheels (well, with spikes). I do not like getting wet, so I choose the velomobile.
But I am considering adding a small snow shield under the 'nose' for the next Winter...

Or maybe I directly build a snow-plow-trike to get My cyclepath cleaned...

Meanwhile in Bonn, Germany: The core of the road has thawed, but the bike part hasn't. So you can decide whether you want to ride your bike on the ice or rather ride on the part of the street which drivers deem reserved for them. Both options suck.

@pekkatahkola do they completely remove the snow so you ride on tarmac or do they compact the snow to make you ride on ice/compacted snow?
Show threadPekka TahkolaFeb 1
@alexantemachina Neither. We mechanically plow the snow away, but a tiny little bit still remains on the surface as you can see on the video. So that gets kind of compacted automatically, not intentionally. It's a really good surface to ride on, but it must be kept as thin as possible. Mere millimeters at best. Because when a thicker layer softens or melts, it will be a nightmare to ride on.
Show threadAlexFeb 1
@pekkatahkola snow slush is quite exhausting to ride on — nah you ride IN it. 😉
What tires do you use? Studded tires or just every day bike tires?
Show threadPekka TahkolaFeb 1
@alexantemachina Slush is a paradise compared to an unevenly softening thick hardpack. Because you never know when and which spot will give way under your tire or not 😅 Anyway, just whatever tires are already on the bike, works. Even better if the tires have small knobs. But studded tires are absolutely not needed. They're only good on ice anyway and usually bad for anything else.
Show threadAlexFeb 1
@pekkatahkola I ride studded tires every winter and they very much helped me through the wintertime.
Where I live people hardly understand snow. They do not really clear the streets from snow — I witnessed they had their snow bucking plate several cm lifted so it had no contact to the roads surface — but they throw salt onto the snow like mad men.
