Winter's here. You can tell: it's started raining. Not that this is unknown in the summer...
One of the common ways of keeping dry when cycling here when it rains is to use an umbrella.
I'm sure it works better with a coaster (back pedal) brake than otherwise, and a lot of bikes here have those brakes.
These two photos were taken within seconds of each other on my cycle home from the shops this evening.
Cycling with an umbrella is actually (nearly) officially sanctioned. The 2005 Houten design standards (which unfortunately are no longer available at this link) referred to making sure that sufficient headroom was available for cyclists with umbrellas.
The second photo shows a variation on the theme. Carry a passenger and they can hold the umbrella for you: leaving both hands free for controlling the bike.
It's almost a safety feature...
Talking of safety, I'm sure that some people seeing this will be shocked. Not only are they holding umbrellas, but there are no helmets, no bright reflective clothing, the bikes haven't got lights on (the photos were taken when it was quite dark and I brightened them up in a photo editor). What's more, one of the bikes is carrying a passenger in a way that is illegal in many countries (not here).
So, is it dangerous ? No. The Netherlands is the safest place in the world to cycle. It is so because infrastructure has a far greater effect on safety than such things as special clothing. It is safe here in a passive manner, due to conflict having been designed out of the streets and not due to people being expected to take care at all times and never ever make any mistakes.
There is a very high level of subjective safety here, which is why you find people behaving like this on bikes and feeling safe doing it. The high level of safety is the case with the cyclists who live here, behaving as they behave. i.e. in wet weather behaving as you see here.
Toby Sterling previously wrote a fair bit a while ago about the safety of cycling in the Netherlands. No extra safety equipment is needed.
