  1. It is another form of twin wheel EUC's and it's downside. Here I can see only disadvantages. Bulky and heavy device, with a small tyre {probably 10").
  2. Thanks. I was asking because I have the same problem. It is not something I cannot deal with, but I am afraid I will miss the warning when I am near to limits of the wheel
  3. Hi, how did you reset the wheel to factory settings. I couldn't find how to do this in de app
  4. Hi, probably, because the battery is heavy, about 2 kilograms, the power cable to the main board is disconnected on one more place. You have to remove the left side shell and to check. On YouTube there is several videos how to disassemble the wheel. Good luck.
  5. Hi, congratulations for the project. There is one successful free open source project for controlling flying rc models. It is used mainly for quadcopters. The basics are the same (but more complicated, 3 axis control and stability) . The name is MuliWii. I think it can help. http://www.multiwii.com/wiki/?title=Main_Page By the way, you have to achieve balance between time for reaction and stability.
  6. As work in gravity =mass *gravity *height, and work=energy, obviously if the we carry more weight (mass*gravity }, more work will be done by it. So more energy have to be absorbed anyhow, dissipated as a heat or transformed to a battery charge. Of course minus the losses, friction and energy required to keep the system alive, which (my opinion) is minimal.
  7. Thanks, it is also my opinion. I just was not sure enough the charger is going direct to the battery or through the mainboard. But something is limiting the charging current. By the way i dicuss this matter with Ian Sampson from Speedy Feet. Hi also thinks the problem is in battery. New battery is already ordered but I have to wait delivery from Germany. I have 9b1 S2 but the charger connectors are different and cannot test
  8. Hi, have you solve the problem and how. I am in the same situation. Battery voltage is 58.4V and would not charge. The charger voltage is 63V down to the battery connector. But the dealer says probably the trouble is in the mainboard and ask me to send the wheel in Germany, but I am in Bulgaria. It will take a long time and a lot of money. Almost as to buy new mainboard.
  9. The Ninebot is again available at https://www.speedyfeet.co.uk/collections/electric-unicycle
  10. Thanks. I am in Bulgaria. Speedyfeet was checked already, but the handle is out of stock and probably will not be supplied. Ninebot Europe may be therre is not online shop
  11. Hi, I want to buy a trolley handle for 9B1-E+, but can not find. Really there is one seller on e-bay (cablemaster) but I dont know is it reliable. Hi sells everything but EUCs. I had ordered one from China, but already 60 days it is not delivered and I ask for my money back. Does somebody knows reliable seller?
  12. Have you ever try to find anything about disassembly of 9B1 in YouTube? BRGDS
  13. Hi. Except the bolt from the side of the pedal, there is a small fixing bolt It is positioned at the middle of the pedal, from the under side. You will need alien wrench, 2 or 3 millimetres. You have to slack it 3-4 turns, no need to remove. I hope this will help Sorry, I red your post again. I suggest that both plugs and plastic pieces from the sides are removed. If the fixing bolt is removed already, spray some lubricant, WD-40, CRC 5-56 or similar, in the hole for the bolt and wait a hour. After that insert fwo plastic pieces in one hole (if there is not room for two, insert only one first) for the side plug, screw in one plug and try to move the shaft, tightening moderately, not to damage the thread
  14. Nex two seconds? My god! If I know where I will be after two seconds, it will be perfect. I agree that we have to take all possible safety measures, but nobody is possible to predict all surprises. Even the route we have to go everyday is changed by the weather, human or so on.
  15. Thanks for the good news. I just bought my E+. Hope to have your mileage without troubles. Wish you much more.
