I justed verified and i think circumference with the 29" backwheel schould be at 2164mm. Or did you choose for 27,5" and afterwards changed the circumference?I just returned from a longer test ride. The zip tie bugfix worked with no problems. 42 km and 1.300 hm accomplished!
This is the cheeb on steroids now! Much better then expected! I pushed the bike really hard and fast on this extended round, and retourned with 15 % battery left. Mode 2 is replacing Mode 3 within my preferred setting, supporting with up to appr. 375 Watt. Mode 3 up to 500W. Mode 4 up to 600+W, Mode 5 I saw up to 720 W peak. The bike performes best with higher cadence, perfectly matching my riding style with lots of support when needed, very very natural feeling. And most important: The derating behaviour is as described from @Kyokushin and @BootsDave. Below 30% still up to 500 W (feels like the the old firmware, fully charged), still 250 W below 20 %. I also changed the wheel diameter from 2274 to more realistic 2168 mm (preset value). Now the deviation to the track record on Relive is appr. 2%, and on the faster side (Display says 40.7 km / Relive says 41.5 km). Very nice. I‘m totally happy, and thanks again to all of You for Your support. And special thanks to @Kyokushin for his patiance and great support! And congrats to @Puschtrale and everyone for getting it done!
