After chasing the fireflies in the 'backcountry' on my bike a couple of weeks ago, I found my back tire soft. Pumped it up - fabulous again. It was a tease. After a whole day at school, the tire was so flat, that when tried to just walk it home, the tire was literally rolling off the wheel. Dame, yo ("bad"). Went to two gas stations and the guys were reeally helpful, but my little French valves were like nothing this little town (or any around here) has ever seen. I finally found new tubes in Fukuoka last week, but in the mean time, I needed wheels. I'd been wanting a folding bike because they're much easier to take on the train & bus, so this was a good excuse to get one. I did a bit of research and settled on this little Panasonic (yes! in fact it DOES come with a radio :) ), and traded multiple gears and shocks for a light load. It's definitely not for long stretches uphill, but it's not bad. And I just love the fact it practically fits in my pocket when I'm done!
