I am a year-round biker but I never had a nice bike so even an entry-level mountain bike like a $500 Diamondback would be a step up from my current 10-year old hard-everything GT which I have been using rain, shine or snow for several years, even in the coldest Yellowknife winters at -45. I had the chance recently to try my friend's Ventana El Gordo fat bike on a trail, and i was blown away. However, I am not ready to spend $5,000 on a bike, or even $1000 for that matter.
