The guy openly admits that the steering is not dynamically stable.....Some people asked me if the python is steerable at all because of its negative trail. In general, bikes with NT are not stable, especially at high velocities or when applying the front brake. But the steering geometry of the python is different, because the construction behaves like a "hanging pendulum". This means that the drivers weight forces the front part into a centered position, thus stabilizing the system....
I'd call that a problem, even though it might appear to work just fine at low speeds and on clean level pavement.
