    Guys,

    Anybody had issue with Error 30 on their bikes? It came out on mine and tried all the usual fix like checking all connections. I even went as far as removing the main harness from the bike and connecting everything outside. Still no luck. Since we have 2 E-09s at home, I decided to swap out the parts one by one to check which component was at fault. From the display to the buttons switch and finally to the motor. I swapped out my motor to the other (working) bike and the error came out. It also caused the system to turn on by just inserting the battery, without actually pressing the power button. Put the working motor back and system is fine. Safe to say it's the motor that's faulty.

    Also wanted to know if anyone has had any experience dealing with warranty from Bafang directly since my bike came straight from Dengfu.

    Thanks,
    Walrus

      What's up, I've had my Luna X1 2000 watt with silent gear for a week now and no matter what gear or whether I'm coasting, peddling or using the throttle the gears are making a constant gut wrenching clanking noise . I've had the derailleur aligned and straightened at a local shop but its still doing it. Put in a support ticket but I'm seeing places Luna is slow to help and I cant find any info on this so any help would be appreciated!

        Remove the chain, hit throttle and listen if issue is still there

      Did anyone convert Luna's X1 stock wheelset to tubeless? Can this be done? I've no experience with tubeless and was wondering if anyone tried it before me.

        The stock wheel set on the X1 is no different than any other, just way heavier than most wheels
        You just seal up the spoke holes, add Stan's and then inflate using high pressure so the bead pops and seats properly

        Watch video's on YouTube if you have never done it before

        I don't use rim strips to seal the spoke holes
        I use 1/2 inch wide Nylon strapping tape
        I go around 2 or 3 times to make sure everything is sealed and that the tape is wide than the spokes holes

          Some useful information on Luna X-1's geometry - first, the actual chart.

          But this is not entirely accurate for our bikes because they come a little overforked - the original Dengfu M09 was designed with a 150mm fork in mind. So the actual stats are a little different. I put the stats from the medium frame into this geo calcluator: https://bikegeo.muha.cc/ and added the Yari to show the changes. These should be the true values for anyone curious.

          Bonus for what throwing a -2 degree headset does to the X-1 geo:

          Aside from a slack 64 degree head angle, most other values go close to stock.

            My July 2019 pre-order X-1 came with the Yari configured for 150mm. Are the newer ones coming setup for 160mm?

            Yes - the product page has it listed that way too.

            A fast electric mountain bike with 2000 watts of power and a throttle. Carbon fiber mid drive beauty.

          Does an upgraded display show watts produced by the rider? Like a watt meter on non electric bikes?

            Yes, the 860C meter shows watts in the lower half
            Below the speedometer.

            A colored indicator appears as the watts go up and down
            it follows the circled area in my image

              Great!A regular watt meter for non e-bikes costs hundreds. I guess a torque sensor on e-bike already collects the data to calculate wattage produced by the rider. I am definitely getting this 860C meter. Is it Luna's best meter?

                Wattage is a simple formula
                Amps x Voltage = Watts
                That can be figured out on the bike without a torque sensor.
                The controller may be doing that math or the meter does the math by getting that info from the battery system?

                  I think we are taking about different wattage. I am talking about wattage produced by rider's muscles not by motor/battery. They sell power/wattage meters build into pedals that measure pressure from rider pushing the pedals and calculate wattage using pressure data plus time it was applied. As far as I understand when you ride an ebike you are not generating any electricity by spinning a motor like you would if you were spinning a stationary motor. An ebike's electric motor just adds torque on top of your torque based on torque sensor data.
                  Am I wrong?

                    For example this pedal has a sensor that measures cadence and power in watts.

                      No, there's no human wattage meter.
                      Try the pedals and see what you get

                        Any idea when the newest round of orders that opened in October with early November ship date are expected to ship out?

                        Disregard this, found the proper thread for this question.

                          The stock display tells you how much cumulative energy the rider has burned in kcal. 1 kcal = 1.16222 Wh.

                            Two questions:
                            1. I installed this meter a couple of weeks ago and the time always resets when I turn it off. I don't take out the battery or turn it off on the bike but everytime I turn the bike on, the time is wrong again.

                            2. How do you reset the trip log?

                              Reset the trip log by holding down + and - simultaneously for a couple of seconds. So easy compared to the stock display it's almost worth the price of admission just for that feature!
