I got a tip that the cranks might be overly tightened. I loosened them up a bit from the 40 something Nm that is stated in the service manual. ( I have no idea what the factory actually used of force to begin with). Things improved a bit. Normal ECO usage on flat roads is a bit more within reach. But I still get a slowdown when I start to pedal from exiting free rolling, regardless of gears, speed and cadence used. I guess the local bike mechanic will be contacted to open the engine and have a look.
- I do have a warranty, but since I imported the bike from another country I feel that spending 100-300 euros locally will save me quite some grievance from customs, waiting, arguing, slow email correspondence,red tape, bad luck etc.
Things tried thus far:
-1a Removing the chain (and battery). The pedals move relatively freely forward by hand when turning the crank.
-1b Putting the chain back on makes no dramatic difference in "hand-pedaling" resistance when lifted up on my bicycle repair stand. It is first when I apply some torque from actually cycling that the very heavy resistance is felt. As if "engine-braking"
-2 Loosening the cranks somewhat. A bit better. All assistance modes benefit and feel snappier.
-3 Bed-in attempt. Trying to thin out and distribute grease by force. Pedaling powered off like a tour de France madman. Ongoing.
-4 Tearing my hair out
Thoughts:
-Bearings are still stiff? Stiffness from lack of lubricants? Bearings about to seize? Clutch(es?) poorly lubricated?
