I usually ride until mid Nov. I store her in Niagara, so I always have one more ride of the season from downtown. Last year I put the bike away on Nov 11th and it was 14°C out. As long as it stays above 5°C I'm happy. I'm going to ride it out as long as possible this year. I even had the wife out to tour around the city yesterday. It was a little chilly, but as long as you dress in layers you should be ok. The only thing that I have his thick gloves to keep the chill out.
