My 1962 Peugeot and my 1973 Phillips Twenty (both fixed gear).
The Peugeot carried me well over 5000 km last year and I'm still breaking in the Twenty which I can really see myself using for commutes as it is the perfect urban assault machine and great wet weather/ rain bike.
It (the P20)is deceivingly fast and accelerates very quickly and the 406 wheels are really built for our springtime roads which are rife with tire swallowing potholes... the ride on the 20 by 1.95 Kenda Kontacts is smooth and between those and the Brooks saddle the bike sucks up the bumps really well. This is good when the puddle you go through happens to be hiding a massive pot hole.
The Peugeot will see a lot more commuting miles this year too as although the Twenty is fast... the Peugeot crushes souls.
And she's pretty comfortable too.
