I bought a fairphone 4 awhile ago from Murena, the only US distributor. Other phones have more bells and whistles but I feel better knowing I can repair it if something goes wrong. If you’re in Europe the FP5 is a good bet but I don’t think anyone is selling them in North America. I don’t know about distribution elsewhere.
Bike poggies are worth looking into to keep your hands warm. Studded tires can help with slipping too
