Spotted in East Cambridge, the make is no mystery - even though it's painted over the bike is clearly a Trek. No, the mystery is what is contained in the locked box on the rear rack.
This commuter bike is well thought-out. It has Schwalbe marathon tires, full fenders, those upright handlebars, an internal hub, and both a tail light AND a red reflector.
The mystery box is locked, and there is even a bit of foam in the lock, presumably to reduce the rattle. What do you suppose is in there? I'm hoping for something super-top-secret. Any guesses?
