PS...
I am a little uncertain why you went for the Flyon based on that. Both Shimano and Brose are well known to have very low levels of resistance above the limit ; have you ridden a TQ back to back and confirmed it's better or even as good? Also I don't get the statement about low weight - these bikes will be amongst the heaviest out there when they land. That motor is a lot heavier than the latest from Brose and Shimano and the battery will be too due to it's additional capacity.
All good points! (Damn

)
You are right, my statement is a too simplistic (and these were not the only factors.)
Since I have never tried the Flyon I am not sure how much it differs from Shimano and Brose in resistance ("0" vs. "some"). Perhaps it is not even noticable...
Also, I do not mean total weight as much as weight compared to performance. Supposedly the battery for Haibike is very high density (48V), which theoretically means lower weight per Wh but that might also just be hype and have no real impact. The lower resistance in the motor should also improve range. Again might not be noticable.
The motor is really heavy, which will be only partly offset by the carbon frame.
hmmm
However, the things that I also like are the design, comfort, the spec, the mixed wheels, fox elite suspension, how good my local dealer is (he has cube and Haibike). Also, some will kill me, but I am not a big fan of Shimano. I would perhaps have dared a Canyon, but I am worried about service locally in Spain. Finally, I dont know any good value bikes with Brose motor available locally. Specialized is here, just too damn expensive vs. spec.
I am the typical idiot who value spec over real-life performance, perhaps.

All these things factor in for me.
In other words, I am taking a gamble, getting caught in the hype. Once it gets here I will be sure to report! (But your comments have made me think...)
