@littlealex Thanks, there is a video on the bottom of the page

Every bike in this video there is going rather slow. I'm not sure if you can go fast with that thing attached. It may self-destruct. In any way, it probably won't sound as cool when you are going fast.

Still a fun idea

@littlealex Is there a video of this contraption? Preferably with sound?

@MrLovenstein I do stress relaxing all the time. It is not very relaxing for some reason.
