Real Bike Cities.

1. Hamburg

2. Rome

3. London

4. paris

5. Other European big and small cities

These europeans cities could be the best place for biker riders, and most
Americna city like LA, NY, Pheoneix, Seattle are the worst place for
biker. The reason is that in America most folks do not ride a bike.
As matter of fact, probably less than 1% of American population are relying
bike as a primary transportation. In europe, I bet that number of population
relying on bike as the primary transportatoin are quite high.

I've never rode a bike in real bike city. Someday I will. I bet that it's not
going to be same feeling to ride a bike among a hugh bike populations verse
a sole rider in big street in US.
