When I was ten years old, friends and I came back from seeing a James Bond movie and were playing at James Bond on our bikes, and I swerved too sharply, fell over, and broke my left leg. I broke both the fibia and the tibula, in fact, but they were clean breaks, very tidy. Hurt like screaming hell, though. As was the custom of the time I was the hospital for several days and came out in a full-leg cast. My father, who lived some distance away, couldn’t get there right away and sent me a dozen roses in the hospital, which made the whole thing absolutely worth it; I had never felt so grown-up!
But that was the end of my bicycling career. For fifty years.
Now, however, I've moved to a small, mostly flat, navigable city, and I want to try getting back on that literal-not-proverbial bike! I fairly often have places to go and errands to run where driving feels silly but walking might take juuuuust too much time, and a bike seems like the obvious option. But do I want to spend hundreds or even thousands of dollars on a new bike and run the risk that I won't enjoy it, or feel safely balanced after so long, or whatever, and will in fact end up not using it much? I do not.
Fortunately this city has a couple of nonprofit bike repairing and reselling organizations! So I stopped by one of them this afternoon and chatted with the head mechanic, and he picked out a bike for me from their (all donated) stock on hand, and we verified that it fits me. It needs some repair work and tuning up, which they will do over the next couple of weeks (him: "There's about six bikes ahead of you in line." me: "It's been fifty years, another two weeks is not a problem!"), and they asked for $125-$175, according to my ability to pay. I wasn't able to actually test-ride it, since it has no tires at the moment, but I was able to balance pretty well; I do feel pretty confident that I haven't forgotten how to ride a bike.
(And this time I hope to learn how to shift gears, too! Kid-me's bike was a three-speed and I just left it in second all the time.)
Now I just need to get a helmet -- which I do know to buy new/unused. And a lock. Whee!
