Yes... you are crazy.
Welcome to the asylum.
Winter is too long here to ride a crappy bike and with proper care a bicycle can survive countless winters without issues and have retired two of my old winter bikes as after numerous winters were still in beautiful shape and put them to use as my touring bike and every day urban assault vehicle.
The new winter bike is also pretty nice... it's is a nice steel Norco mtb which I expect to use for many winters.
