Recently I purchased a used mountain bike, for both leisure and commuting. I only live three miles from work and two miles from grocery stores, so it seemed like a good idea. The handlebars keep coming loose, though, so now I know why I paid more for my pump ($16) than I did for the bike ($15).
I'm very interested in bicycle commuting, and have for the last few months been researching the ways cycling is promoted in Amsterdam, Copenhagen, and Portland (Oregon). I live off a busy highway, so the first quarter of any of my route would require riding off-road, hence a mountain bike and not a road bike.
Do you cycle? What do you use your bike for? Does your community support cycling as a transportation option?
