I vote bad idea. Not necessarily because of the rocket propulsion or stupid-fast speeds for a bike, but mostly due the the fact that a crucial rocket component that looks very apt to explode is replacing the top part of the bike frame and this “probably-gonna-explode” cylinder in basically strapped to this guy’s testicles. I’m no scientizer, but it seems like the week link in this experiment is 2 inches from this Swiss manhood and that is just my assesment of the situation before the rocket pushes a bike at very fast speeds. Somebody has to have this record though and I’m glad it isn’t me.
