1972 Raleigh Sports Standard. It has been with me since 1982 and has seen well over 35,000 miles of riding with minimal maintenance. It has been repurposed as a beer bike with enough baskets to haul 3 cases of beer.

I also use it as a grocery getter. Currently the only maintenance it sees is having the tires pumped up to pressure prior to throwing a leg over and rolling up the road. It hasn't always gotten the white glove treatment, but has always been ready to roll at a moment's notice.
