modification of the motor into 2 directions

modifying the antique motor is something that some people like, in modifying the motor a lot of ways and styles that will be done depending on the desire and creativity of the person.
but this time my best friend modified his antique motor in a way that is very different from others generally.

my friend modify his bike into 2 directions, if this bike is standing or not a big way we probably do not know where the direction of the road or where the wheels of this motor will spin.
