If that ist still a Rebel I would say it's up to debate or opinion.
Of course a bike will always bee bike A or B in the title (also this may depends on local laws) .
In my opinion if a bike is so modified beyond a point where it becomes a other kind of bike, which is the case here, it should not be compared with a (relative) stock one.
Wich is the Point if this thread, I guess.
Anyway this is just my opinion and the bike is cool nevertheless.
Of course the Question arises why do such modification to a bike like the Rebel?
The answer must of be of course:
For the Fun of it.
