I am a female bike commuter, I have stopped commuting by bike for a while due to the early time it get dark in the evening and all the people on the road. The morning commute in darkness does not bother me as there are not many people on the road, and I also if it snows I will not be commuting by bike that day. I have commuted by bike in the cold (18f) so I am not put off by that. I was seeing a woman that was commuting home in the afternoons but due to not riding have not seen her lately.
