Things most people don't know exist.

Battery chargers. The ammount of bike lights I see that are dimmer than the infra-red emitter on my tv's remote is quite astounding.

People who own cars and choose to cycle to work instead

Have we mentioned mudguards?  OK, they may not be so useful this morning (except for the fact that my front one protected me from a spray of gravel I heard running through it from the heap of leaves swept up into a pile across the full width of the segregated cycle lane near Newington), but last night I got the benefit of loads of spray again.  Now, I'm sorry if it spoils your Bradley fantasy, but there are other riders than you on the road.

Oh - and that wet strip down your arse?  You look like you've hit double incontinence.  Not covered in Rapha videos.

[Cudzoziemiec]

Scrapers to clear windscreens.

The thing on rear view mirrors to flip them slightly so they don't dazzle you when a car is behind you.

I just had to do 1200 miles, mostly in the dark, in my new low-level car.  Thank you SO MUCH.

Cyclists who move at more than 20 mph, rather than slightly faster than walking speed. This usually becomes apparent when a motorist clocks a cyclist approaching the side road he's about to pull out of.

Even fewer realise that there are cyclists who sometimes move at 30 mph or more, especially down hills. This is proven by the number of motorists who overtake cyclists who are moving at or above the speed limit.

That it is possible to cycle in legwear other than shorts.

That it is possible to cycle in legwear other than shorts.

...or jeans.

[Cudzoziemiec]

Jeans at least make sense. If you're not riding far or fast and you're going somewhere where jeans are appropriate, then jeans are good. But shorts when the temperature is around zero are not good, especially in the long run.

Access to Work - government support for disabled people in the workplace: https://www.gov.uk/access-to-work/overview

Met a disabled person who works with disabled people and was a health professional working in rehab of disabled people in "life" this week who had never heard of it...   

[Charlotte]

That it can be quite legal for a young person to carry a knife.

[clarion]

That should be in: Things the Polis don't know.

Jeans are rubbish when it rains. They get wet through and take ages to dry out. This is also why they are rubbish for walking.

Along with -

That it is legal to take photographs in public places, whoever or whatever* is in them.

*As long as it isn't either (a) pornographic & including or appearing to include persons under 18, or (b) of a kind likely to provide practical assistance to a person committing or preparing an act of terrorism - which in practice, generally requires other evidence or suspicion of involvement in terrorism.

[Palinurus]

Solder paste.

[Phil W]

That you can get oil for your bicycle chain and that applying it will prevent it turning into solid peice of rust; you do not need to wear lycra to apply said oil, nor do you need a fancy handshake.
