Supercycle from about 10 years ago. I used this as my winter commuter for years and it's practically indestructable. Comes with lights, fenders, and rack.
20", hardtail, steel frame. 18 gears total (3x6).
It could probably use a little tlc but it works. The back brake makes a lot of noise but that's useful for when joggers can't hear the bell over their ipods.
