I'm a daily commuter. Rain or shine, hot or cold. Mid-80's (French-made) Peugeot Avoriaz with panniers and a trunk bag, plus a basic run-of-the-mill "bike computer", bell, mirror, and blinkie lights front and rear. Need a proper headlight for when it gets darker. Thinking about a Digital Emitter.
I've got a relatively simple 6.5-mile commute on a paved rail trail next to Lake Champlain. Could be worse!
