I can't help feeling that the German opinions on the Bosch system were coloured by national pride. It doesn't appear to me to entirely live up to everything they've said, sounding not too different from the Yamaha and latest Panasonic units.
As you say though, it has it's benefits and I'm sure once you are more used to it, you'll get more from it. That's always been the case with the Panasonic unit.
That's probably a key point made by Flecc in his last paragraph. I should imagine that anyone used to the more powerful hub-driven bikes would feel underwhelmed by a Panasonic or similar crank-driven bike. If one is keen to make some effort and behave as if on an unassisted bike, the crank-driven models will be rewarding in use. Powerful, hub-driven bikes which can master the steepest hills with little or no need to pedal may have a place but ultimately, cannot be regarded as bicycles. They are, for want of a better description, mopeds but without an internal combustion engine.
I'm not knocking them but they do seem rather primitive when compared to the best pedal-assisted, crank-driven bikes. Each has its place and it's good that we have the choice. One day, given my prognosis from my cardiologist today, I may decide to add a kit to one of my regular bikes but I'll continue to attempt riding it "as is" until that day comes.
It never surprises me that the "boy-racer" element within the forum rave about the really, really fast, (and invariably illegal) hub-driven bikes cobbled together by blokes working in sheds. Those who are engineers or those with any understanding of, or empathy with, electro-mechanical things must appreciate the simple but effective science and the sheer engineering elegance provided by the chaps at Panasonic.
Like Flecc, I remain to be convinced that the new Bosch-system machines represent a new dimension in ebikes. I suspect the hype may be a triumph of marketing over engineering truth but time will tell. I'm bound to say I shall be surprised if Bosch can come out of nowhere and produce a radical, new crank-drive motor for bikes when all their other electrically-powered equipment, whether it's gardening machinery or industrial tools, could only be regarded as adequate, rather than special.
I'm happy to be shot down in flames if, in a year or two's time, Bosch-powered ebikes are regarded as the "Rolls-Royces".......or perhaps that should be "Porsches or Maybachs?".....in their field. If they are any good, I may even buy one!
