This is not entirely true.......reflectors are made up of a series of "right
angle reflectors" that allow for light to return back towards its source.
This effect can be seen where there are two mirrors at right angles.....no
matter what angle you are at, if you look at the mirrors, you will be
staring back at yourself. The best way to understand it is to draw a
picture of a right angled reflector and then draw "beams" of light at
various angles (remembering that the angle of incidence will equal the angle
of reflection). The "return" beam will always be parallel to the original
beam.
Having said this, I don't have these reflectors on any of my bikes. I do
have stick on reflective material on the sides of my backpack though and I
used to have the same stuff on my crank arms but it started getting a bit
tattered so I took it off. I haven't tried sticking reflective tape to the
spokes but I might have a crack at it as I have some left from when I did my
backpack (BTW, I scored some offcuts of red, orange, and white adhesive,
reflective tape from a road sign shop in Queanbeyan some time ago for about
$10).
