Winter weather can be ruthless. Whether you're talking slush, sleet, furries, ice, I can go on - you gotta be careful out there. Mother nature is a selfish force.
The cyclists who keep riding around during the winter are a rare breed, and should always be cautious, as the video below clearly shows.
This Montreal cyclist almost gets completely run over by an oncoming vehicle after sliding and toppling over in the middle of dense traffic. Needless to say, it was a close call.
As a consequence, unless you're a seasoned cyclist, it's always advisable to store the bike away during the colder months.
