  1. Sorry for late reply. Sorry to hear that, that is bad news. At least you know the problem.... Perhaps the previous owner deeply discharged the wheel and left it at 0% charge for days/weeks/months. In this case both battery packs would not be safe, better not use it at all. The risk of fire is not worth it, these things can burn the house down... Maybe buy 2 new battery packs from kingsong? Unfortunately, this will not be cheap
  2. I think it is interesting! At the time of the crash only 2666 W power and only 38 A current! I have had reached 4000 W on my 16x and it was fine, but it was at much lower speed than yours. This supports the theory that at high speed the wheel just lacks voltage due to high motor back EMF. If so, this wheel is quite unsafe above 40 km/h (=25 mph), which is what you've been saying. Thank you! Indeed you are providing the community a valuable service! I will personally try to never exceed 40 kmh = 25 mph on my 16x.
  3. Could you please share your wheellog log around the crash?
  4. This has been my experience as well. To match GPS I need to adjust speed by -6%.
  5. Difficult to say, but my impression is that v1.07 hard is harder than v1.06 hard. That's good, there is a difference in the riding settings and everyone can pick their own.
  6. Hard to say, but I think the hard pedal mode got harder pedals. After upgrading from v1.06 to v1.07 I changed pedal mode from "experient" (WTF??) to "riding" mode to get the rocket feeling back. The softer pedals feel much more fun to me. Whoever is complaining about v1.07, I would first ask if they had tried all pedal modes.
  7. Just came back from riding v1.07. It allowed me to go 32 km/h GPS speed (= 20 mph GPS speed = 34 KS km/h = 21.25 KS mph) down to 65 V under load (= 70 V no load). Didn't even test at lower battery charge, I don't wanna go lower. I like this very much, highly recommend to upgrade from v1.06 to v1.07.
  8. This! Voice control -> voice speech switch. Doesn't help with the tiltback, but it makes much more bearable. Let's wait for v1.07!
  9. 16X is the best wheel for me, but there are also some problems.. Dust inside the wheel is not good. Speed limiting from 50% battery is a problem for those you want to ride >30 km/h. People are passionate about the wheel, it's an amazing wheel, that's why there is passionate to talk about the problems.
  10. Looking at this wheellog log, he discharged the battery fully (cell 3.26 V) at which point he either overpowered the wheel or the wheel turned off.
  11. According to Kingsong posts the speed throttling seems to depend on voltage drop during load. Took me whole day to make this graph, each point is a tiltback event. I don't think anyone else has done such extensive test. Just to be clear on the numbers.. Idle at 76 V, that is around 50%. Driving just from wind resistance the voltage drops to 72 V. Get tiltback at 40 km/h = 25 mph reported speed. Speed gets reduced further as the battery depletes. There is an additional problem that the wheel is reporting higher speed than GPS, so the actual speed is even lower. Ma
  12. I have done a lot of diligent calibration with GPS and for my wheel: gps_speed = 0.94 * ks_speed Real (GPS) speed throttling graph:
  13. If you want to ride above 40 km/h, those tiltbacks will be really really annoying. And they start early, from 76 V idle. If you're happy staying below 30 km/h (=32 km/h wheel speed), then 16X is an amazing wheel!
  14. Just came back from riding v1.06. Logged all the tiltback events, here are the numbers after digging through Wheellog's log. Kingsong reports higher speed compared to GPS, to get real speed I correct kingsong's speed by factor of 0.94. KS16X v1.06 tiltbacks.ods
  15. What about self discharge? If some cells have higher self discharge, they will drain the good cells that are connected in parallel with the bad cells.
