In winter, I ride between the hours of 10 am and 3 pm, that is in daylight but if weather is dull, I use lights too, including a built in light at back of helmet. Never ride on rainy days or if temperatures are below 7 degrees to avoid icy roads. I also use the same bike on every ride, that is my Specialized Allez which is my designated winter bike. The other three bikes wait till the spring before they go out. I also tend to do shorter rides in winter because I lose some of my fitness due to not going out as often. Not very keen on using the turbo either , boring.
