Three for me.

The "A" bike, the main commuter, a Trek 4300 with the classic milk crate attached to the rear rack, a 5 amp-hour battery in a wooden box bolted to the frame, and a 20-watt halogen headlight, and fenders of course.

The "old-man" errand bike. This is a Schwinn Suburban that I got for free because the shifter was broken beyond repair. It is locked into a single speed, and at some point I will convert it to a real single-speed or put on an internal hub. It is used for errands because it is (I hope) less of a target for theft.

The "multi-modal" winter beater. This is new and not completely on-line. It is a used Diamondback something-or-other, a bit of rust, some chips on the paint. It has less stuff on it so I can lift it onto the bike rack on the city bus and extend my operating range. It can be used as it is, but I want fenders, lights, and a more comfortable seat before I use it regularly. In November, it will get studded tires and be the winter beater, so I can become a four-season biker and earn my coveted winter certification.
