The 650b wheelsize, also called 27.5, has become very popular in the mountain bike world. At 584 mm, it's the "just right" size for many mountain bikers, in the middle between 26ers (559 mm) and 29ers (622 mm). 650b has also become a popular width for cross and "gravel" bikes. From a transportation bike standpoint, the advantage of 650b is that it lets you run wider tires for a cushier ride. Jan Heine of Bicycle Quarterly raves about the advantages of 650b tires in his "remarkable journey of discovery" series.
Another thing to like about this bike is its 11x1 gearing, which means you get plenty of gear options without having to deal with triple or even double chainrings. This really simplifies the ride.
Finally, I should admit my bias for retro steel bikes. This one just looks cool.
And while I'm admitting biases, our love for Breezer should be clear by now. In looking for bikes that met our standards, we started with Breezer. Our first bicycle post in Feburary 2008 was about the Breezer Citizen. Our second post was about the Breezer Uptown. Breezer just makes solid transportation bikes, and they keep getting better and better.
There's been a lot of hype about the Doppler Cafe. Here's a sampling:
