I think we could all do with some positive energy. Ground rules:
Post a picture of the bike or bikes, and tell us the one thing you love most about it. Even if the bike well and truly sucks, find something good about it!
Dahon Curve D3. This three-speed bike is now a two-speed bike, and doesn't hold together as well as it used to, but it's a fun little bike and I commuted on it for a year and a half. I think the coolest thing about it is the saddle. When I wanted to replace the stock saddle, I posted a thread here asking for suggestions. Someone here told me about Rido saddles, and offered to mail me one at no charge. From England.
I replaced the Dahon with a Bike Friday Tikit. I have not yet found the words for how awesome this bike is. It's not really a folding bike, but a bike that folds. The two of us don't have much history together yet, but my favorite attribute so far is that I can climb hills on it that give me trouble on my Randonee touring bike.
