I received my new 905 yesterday and went for a ride. All I can say is it was hard work. I’m fit and a regular cyclist. It appears throttle works but assist not helping. Whatever level of assist is selected no difference is felt. I even switched off and the effort was not noticeable. I’m waiting to talk to Wisper. I’ve called and emailed and tweeted but nothing yet. But for now has anyone else experienced any similar issue. I did call the dealer but they were very vague and didnt seem to have knowledge.
