I asked, and my employer offers neither the transit, parking, nor bike versions. The parking one makes sense, we have a vast campus and plentiful parking. But I couldn't tell you why not the others. Except that they've been nickel and diming us for years (this year the HSA match shut off at a lower income threshold, they went from 80 to 48 sick hours, and for the old-timers they deleted the 200 hours at 20 years vacation level).
