As far as winter riding goes if it's only short 10min journeys then you should be fine, but the worst thing about winter is the cold. Cold is a danger and you concentration will go tits up as you body goes into survival mode. Even breathing in icy cold air can hurt your lungs and stuff, so when it's below zero wear a neck/face mask, wear warm gloves (Gortex is my choice) long johns are a must and use a layering system to keep warm. 70mph at about minus 1 will have a winchill factor of something silly like minus 30. So at minus 5 and more you getting into arctic conditions at higher speeds. Hyperthermia is reality. So unless your like the rest of us crazy people that go out in all weathers stay at home wrapped up nice and warm with a hot water bottle
