    a man in the review business told me that they had problems with the rubber for a while. But there was never any warranty for tires except the armadillo tire.

    I like the short bikes more than the long ones, because they are more maneuverable.
    But I am going to build myself a long one because they are reportedly easy to balance at slow speeds.
