Should I ride my first fixie back from the shop (in London)?

Oh, Ed, you're crazy if you think London isn't dangerous! Try riding in NYC and then tell people it's not dangerous here. It's freakin' insane crazy time riding in London! Of course, you get used to it and someday, years later, learn how to navigate without constantly looking at the A-Z.

I'm with Ed, London isn't that bad to ride in.

Traffic is slow moving and the drivers, are for the most part, aware that cyclists exist
