I was wondering if any seasoned veteran could advise me on certain dos and don'ts with regards to riding my bike in the winter. Here in Southern Ontario, we still have somewhat cooperative weather and so I still tend to use my bike as a daily commuter. As a person who only has this as his only form of private transport, I would like to do it as long as possible before I have to take the bus. The one thing that keeps me excited to go to work is... the 15-minute ride there. However, I'd like to be safe and I understand that ice and snow will come and these are days that should be avoided. The question is... when should I be expecting ice? Are there any indicators?
