It definitely seems appropriate to target winter riding advice during this time of year - at least in this hemisphere. For those in cold climates, keeping your hands warm and still being able to maintain finger dexterity can be a challenge. I have some neoprene bike gloves that work pretty well for keeping my hands warm, but if I want to undo zippers or even buckle my helmet on, I have to take off a glove. I just can’t feel very well through the material.
Handlebar mitts on motor scooters are fairly common, but it is rare that I see them on bikes. had Nickjohnson’s flickr photostream provides a simple hack to try to keep your hands warm on cold rides. Here is Nick’s description:
When the weather gets cold, some people put on gloves. Personally, it’s always bothered me to have anything between my hands and the brake levers. Here’s another solution: “moose mits” are insulated mittens built around your handlebars. You slide you hand inside, and have unencumbered access to your brake levers, but your hands stay warm.
This is the simplest design possible: I wrapped an old t-shirt around each brake lever, and tied it in place with an old inner tube. Voila. Warm hands.
