Floor Wax & Dessert Topping
As Kent Peterson sagely points out, bicycles are neither floor wax nor dessert topping, but they really do get you places quicker than walking. Also, fenders and racks keep you dry and comfortable while carrying heavy things. And gears are nice to help get you up hills or when dragging something like a BOB Yak trailer long distances (as in 10 years ago when I “portaged” 50 pounds up PCH-1 from the Bay Area to Olympia). So yeah, bicycles are pretty amazing.
And I agree with Kent. I don’t personally care if you wear a helmet or not, or if you’re a Dane obsessed with proving a causal relationship between cyclists wearing helmets and traffic accidents. Do what you feel man, but please do get out and ride.
