Not my first language, so sorry for confusion. The retailer did the last repair with the nuvinchi gears that made the problem more noticeable. The importer changed the motor this summer. None of them want to look at the bike so I need someone else to do an objective test and I do not know what to ask to be done. I need a documentation so my I can ask to get a refund and give the bike back.

Tank you danielrlee. I just need some way of proving that point. Would a retailer measure it?

How can I objectively assess the poweoutput of the motor and if the battery is being used sufficient?

I want to sell mine too as I am fed up! But I also don't want to sell it with faults and give someone else a problem. I want the manufacturer to take responsibility. Its a very expensive bike!

You also had "trouble" using up the battery?

Thanks. But thinking more about getting one replaced as Scott was so confident that the issue is just for some bikes. I already had 2 replacements for the motor. I live in Norway and have gotten a lawyer, but the seller is not cooperating at all. And blaming me for not using the bike correctly.....

So how to get new motors to my Kalkoff bike that is not giving enough power/assist?

Hi. I have a 2015 Kalkoff Dover Impulse XXL. I had 2 replacements of the motor and after over a year of trouble I just got my gear fixed. The trouble is having less power on the hills. The motor seems fine for a while and then it looses its power. I can not seem to use up the battery eighter. The seller will not touch it and I want to know if anyone else has this problem and if there is any way to check the motor to see if it gives the right help/power. Thank you.
