Bicycle naming usually does not become extreme, you'll find a lot of 'city rider' or 'explorer' or maybe even a 'tour de luxe'. But in this case Crescent has broken new ground.
I had to look up what a Positron is, as my particle physics knowledge isn't too hot. But naming your new bicycle design after the anti-matter equivalent of the electron.... that's good work. Even better to have reached number 5 in this series!
