Here in the UK we've had a bit of hot weather and as usual every Englishman gets all in a fluster (it's the same when we get a little sprinkle of snow too). However, having ridden my Scout from one side on London to the other on the hottest day of the year, indeed the hottest day on UK record I did get thinking about what people wear when its hot. I passed many people on scooters and bikes in nothing but t-shirt, shorts and trainers but this is London and accidents happen, a lot! Personally I wouldn't dream of riding without protective gear and in my short time as an ex-pat in the US I was even laughed at for riding in a helmet. However, I do believe that each to their own but that said I do wonder what other people think on the matter? Doing a bit of research I found these videos on the topic.
