Thanks.
When the weather cools down a bit I will wear my helmet less, I tend to wear a thick wool felt dockers cap during the cooler season. Except on the open road on the other side of the frontier where there is a 200€ fine for not wearing a helmet...
Like I have said many times on this forum the only helmets I believe in for security are full face, just look at the recent photo of Sir Richard after his accident to see why. The current legislation in France for s-pedelecs requiring a motorbike helmet is ridiculous, even dangerous. It is the principle reason I didn't take out a loan and buy an s-pedelec in the first place.
