I want a durable bicycle and I doubt the durability of a folder with a hinge in the frame. Brompton and Bike Friday seem better, and I've been told that Bike Friday provides a lifetime guarantee. Dahon's guarantee is five years, which in my opinion is a poor investment.

The mini velo may not be popular in North America (4% of the world's population) but I like it. If made of standard parts, it'll be maintainable and durable.
