I'm thinking of doing something similar to what Antti did.

How wide is your front tire, Antti?

Hi,

I live in Helsinki and have the RadWagon4. I have been through 3 Finnish winters with it. In Helsinki the temperature tends to fluctuate around freezing throughout the beginning of winter and then stays below freezing in Jan - Feb, so we get lots of slush, ice, and re-frozen semi-melted snow, with lots of bike-corroding salt thrown in for good measure 

I noticed that the stock RadWagon tires are slippery in the cold and they have almost no lateral grip in icy conditions. I've taken several falls when the front tire slipped out from under me. This makes riding in the winter very unpleasant. I don't like having to be "on edge" the whole time.

Last winter I laced up a 24in rim to a new front hub and used a 24in studded winter tire at around 3 bar of pressure. There were no tire clearance issues, and it completely transformed the bike. The grip, even on ice, was much much better and I felt a lot more comfortable and safe riding around in icy and frozen conditions. I just left the rear tire as stock. There is some slippage from time to time, but the back sliding out isn't really a problem.

Getting a new rim for the front can be kind of expensive, but if you are serious about riding around in the winter I would recommend it. I would say forget the snow chains or moped tires and get a studded tire.
