Saying rings true to me...How many bikes do you need. One more than you have..
I have four bikes...I need one more..I need a beater bike for riding out in the rain.. All my bikes. Don't / won't take out in rain. I have a Klein for when I feel fast. A Fuji tourer for heavier touring..and a Surly Cross Check for light commuting.
I do intend to get a top notch tourer bike for when I do something serious. Still need a beater bike for the rain.
My wife has a Nishiki Sport hybrid, which I often ride about town at night for errands.
