To those who said "pimp my bike"...
check
this out.
"Danke MTV, für pimping mein Fahrrad so geil!"
Also, to the wobble wobble. Speed will help with that a bit. The gyroscope stuff and all. The wheels will keep you upright a bit easier when they spin faster.
Vision is the best thing for riding a bike too. In a car they say you should look ~10 seconds up the road. On a bike, you need to know what's 10 seconds in every other direction as well as increase the forward vision as much as possible. You can still see what is directly in front of you while looking far ahead. And if you can start to listen for what is around you too, that will help. Listen to the cars coming, listen for bells, and the sound of other bikes (wheel noise, pedeling noise, loose bolts jingling). That will make life so much easier when you can ear/see what is around you. Especailly cause you will be less likely to get yourself into an emergency situation (not that it wont still happen, just less often). I definitly saved my own arse about three weeks ago when I was able to hear a car on some gravel before it shot out of a blind driveway right in front of me. The guy had his wheels fully locked just to avoid going into the street, and definitly didn't give a second thought to the bike/ped path that he was crossing. Had I not heard him coming, I would have run right into his door or been hit from the side by his bumper.
And I'd like to add in one other thing. As it is summer now, this will be a big thing to remember (it almost caught me out about two weeks ago). When it is sunny for a while, i.e. no rain for a couple days to a couple weeks, the oils from the cars will stay on the streets and not be washed away. The next time it rains, it will be reaaaaalllly slippery. So do be carefull when riding in the wet. I took a corner in the wet about two weeks ago, and something didn't feel right. Took the next corner, and it felt even worse (and was going faster). The next corner I almost didn't survive as the front, then the rear tires slid out and almost threw me into a car. It was nothing more than luck that I didn't cheese-grate my leg at the very least. It was only then that the light from a car was enough to show me the rainbow colors of the oil on the road.
