Well.

I can bring my bike inside -- on sunny days, it stays in my office; on wet days, it stays out in the warehouse. There is a shower I could use if I clean it out, but generally skip it.

Of 14 people I work with, one cycles for exercise on a regular basis, either rides at lunch or on a trainer at home. Two are into fitness and appreciate that aspect of it. None really understand the whole bike-bus-bike commute thing and regard it skeptically, but we're pretty laid back, all of us have our quirks, so no hostility, some curiosity.
