I normally ride a low racer on my regular commute to and from work. Occasionally, when it's dark I fail to see bumps in the road and give myself a bit of a scare. I have pretty good lights, but looking through your feet, cranks and cables at 40kph on a wet bumpy bike path at night is a bit of an extreme sport. So after 5 years of riding almost exclusively on recumbents (and many more years before that on a mountain bike), I decided in the name of better visibility and thus safety to get an "upright" road bike.
A Cannondale R2000 with some fairly nice shiney bits off
ebay. Its light and the previous owner had put a very nice set of integrated carbon bars on it, in fact once I got over the sore butt and the extra effort required to get from a - b it has become a trusted mate.
After 4 weeks of aclimatising my muscles I was starting to get some good speed, and quite enjoying not standing out like the proverbial balls on a dog when, on my way home, down the usual bike path I hit a bump that I hadn't seen (the irony is not lost on me

lost control of the bike, careered off the path hit a tree, gave myself a bit of a knock on the head, buckled the wheel, snapped the handlebars ($600.00 dollars to replace apparently) cut myself up a bit and critically injured my pride......gutted.
I have had it fixed and am going to ride it to work tomorrow - get back on the horse and all that

I am not sure that my safety assessment was so brilliant.
Good luck out there everyone

Its not always the drivers you need to watch out for!!
