When I was teaching in Poland, I don't remember anyone other teacher and only one or two students cycling in any of the schools I worked at. But equally, nobody minded at all. I always used to park my bike in the "teachers' room" or "social room" (where the tea and coffee are) and nobody complained.
When I was editing, one other person said he was going to cycle in once he'd moved house and got his bike out of the cellar, but I left before he did that. Still, we had a cycle rack in a locked car park which only the top bods got to park their cars in. I think someone once passed comment on my long legging things one winter's day, but it was more ribald than animositive (shit, what is the adjectival form of "animosity"? Brain failure!)
Here in India, I'm again the only cyclist out of about 250 employees, though I know many employees of the other companies on our "business park" cycle. They work for companies like IBM and Microsoft (I work for a completely different firm which has somehow found itself on the same development). One other guy asked me for advice about buying a bike (and then ignored it, but I think he's happy with what he's got, so that's ok) and was going to start cycling once we'd moved office, as was one woman, but neither of them have. Perhaps they were put off by my crash and hospitalisation which unfortunately coincided with the move, but I don't think so. I think a bigger factor is the free cabs Indian employers provide! No one regards me as strange though, and there's no animosity.
But eccentricity is definitely a factor - when you're A Foreigner you can get away with a lot more, especially when you're A Crazy White Man (or Woman) in India. And the English have a reputation ofr eccentricity anyway, though I'm not sure why.
