A fixed tourer with panniers and dual brakes would be nice.
I ride a 1955 Raleigh Lenton fixed gear that runs a 46 up front and an 18 and 16 on it's flip flop hub and my longest ride this year (on this bike) was 90 miles of rolling hills and steep headwinds... I could have easily ridden farther but had some time constraints.
I ran the 46:18 most of the way so that I wouldn't drop my riding mates on the flats and needed the lower gear on the way back due to the high winds and still was pulling folks most of the way.
This bike fits me like a glove btw.
