Id like to think its a little while off before I wear anything out although saying that I went through 4 Bottom brackets in a year before I discovered ceramic bearings and a Hope BB, so you never know.I shall look forward to your review I'd have preferred more than 3 power settings, although they may have judged them perfectly.
Also when things wear out on the motor you should be able to get spares, whereas with the Bosch no motor spares are available.
OMG did you just write a post in English?
