This is the sort of thing I use about town.
1980 Trek 510.
Sometimes it gets a first generation Burley DLite for hauling stuff around or carrying the dog father then he'd run on his own.
The back end is a modern Sturmey (SunRace) S-RF3 controlled by a vintage Sturmey trigger shifter on the bars. This beast gets ridden all year 'round, and I've certainly ridden it with a pint of bitter in me. Note: I don't ride my bike when severely inebriated, and I generally avoid that state.
