Bicycle was my only mean of transport when younger.

I still have the bike I received at 13 or 14.... But it needs a bit of repair ....
So I bought a new two years ago.
But I use it rarely, mostly during week-ends, to run some errands and to do some light shopping around. It's quite dangerous to ride a bike in Paris....

I'm no longer a specialist in bikes (and have never been anyway...), so I'm no longer aware of all the gadgetry available nowadays...

I would like to replace the front dynamo driven light by one running on AA batteries. Just to make it legal. I don't ride a lot at night.
And my Inova T2 is bright enough (but the way I strap it on the handlebar is not ideal)


As for "lateral protection", there are glow_in_the_dark things you put over a few spokes on each wheel.
And a reflective jacket is a good thing too.... I guess you can find such a safety vest in any car supplies' shop. I even saw some in a supermarket, in the automobile section.
