My wife commutes occasionally on her Bleriot. You hear a lot of nonsense about 650b bikes by people that have never owned one.

I like hers so much I want to put one together for myself. The 650b tires are these
big pillows that run at absurdly low pressure. They simply roll over a lot of stuff that would cut other tires because they are softer. The ride is exquisite for the same reason.

If you do something like QPB's package program, you can put a 650b together for a reasonable amount of money.
