It had -18°C in the morning, but I was warm until I finally started my Piaggio Quartz 50 with the kickstarter. E-Start didn't not work anymore. 60km into office, usually 1:25-1:30 h:min. The roads were almost free of snow and I needed only 1:40. Although I was dressed as fat as possible and had no locally frostbite, I was totally chilled and that lasted until noon.
On the way home it was warmer and easier, thermometer at home showed only -15°C on arrival.
Personal record -27°C (with the bicycle to school, forget the diesel powered school bus).
German record -45.9°C (Funtensee meteomedia weather station 24.12.2001).
Petrol freezes at -45°C, Ethanol at -114°C. Clear advantage for Ethanol fuel!
