I'll start off by say I'm new to this forum and have done a fair bit of research on this topic already, but I feel there are many lingering questions I still have.
So here's the deal for my situation. I'll be commuting at best 4KM's to get to work and instead of buying a car, a bike seems far more practical and environmentally/health friendly. That being said, the winters up here can be extremely harsh (-40 C or so) and I'm well aware about layering and such to keep warm.
But the primary issue I'm running into is regarding what kind of bike I should buy. I've read a fair bit on this topic and I feel overwhelmed as to all the options out there. From what I gathered for winter commuting, it would be best if I purchased a bike without any suspension because in my climate it would wear down quickly. Is this really the case? I'm not overly concerned on price, but I'd prefer to be frugal and save my coin. Any ideas on what a solid bike to buy for winter commuting would be? Also, would I want to swap from like studded tires to regular tires in the summer?
As this thread expands, I'll get more into the deeper questions I have. But as it stands, I'd just like to get a couple opinions about my current situation.
Any help would be greatly appreciated, this is all very new to me.
