    I did some testing on my Luna BABE today. It is not available with Ludicrous. The power outputs in PAS levels 1-5 are night and day. Like 45-980 watts . But using throttle the output is much closer. Using throttle only: 380, 540, 650, 770, 920 watts. So with a Ludicrus controller doubling output at level1, you should be getting 750 watts or so. Not full power, but equal to any street legal 750 watt drive.

      I want to change the chainring to a 42t. Can anyone recommend one or have used one that works with the bike?

        it might not fit, 40 was the biggest I could fit on my large frame

          Bump, Could really use some torque values!

          Do any torque values exist for the bolts that mount the motor to the frame?

            I have a couple of the 40 tooth Snail chain rings.
            Big improvement on my X1.
            The stock 32 tooth was way too under geared for off road

            I have seen people on FaceBook that have put 42's on their X1
            A longer chain with 126 links is needed

            You can get the Snail rings cheap on Ali Express here


            You can also get them on Ebay

            You can see the 40 tooth on my X1 here



            And here

              What chain did you end up going with?

                Not sure if the M600 uses the same sampling frequency as the Bafang Ultra but this might explain why the torque sensing / power delivery characteristics of the Bafang motors can't simply be tuned without a proper controller:

                  We are happy to announce that we are now the exclusive North American distributor of the Archon X1 controller for the Bafang Ultra drives. This completely changes the landscape for powerful mid drives, and brings the riding experience on par with the top mid drive motors in the world.  Don't believe us ? Read on! Where we are today - Raw power! The Bafang Ultra is an excellent motor,  built to last for a long time. It is also easily end user serviceable. This that adds to the popularity of the motor. The current controller is very powerful and there are vendors and Bafang partners who have been able to get as much as 2500 peak watts flowing through this with no problem The core issues we were trying to address were 3 fold  There is a small delay in the assist kicking in - feels a little sudden.  You can see based on various user posts on the forum, and also some of our experience. The assist ramp up isn't smooth. It also tapers off and goes in and out as you ride at higher speeds. The motor is a power hungry beast. It takes a larger battery to get similar range. How did we resolve these issues and improve ride quality? The new Archon X1 controller option gives us near instantaneous feedback and assist. This is because we are sampling the change at nearly 9000Hz. This brings us on par with the top mid drive motor providers out there. We need the higher sampling in order to detect minute changes in pedal cadence, torque applied, and the current speed. Higher Sampling, World Class   The image above illustrates how Archon X1 sampling compares to stock controller and industry standards.   The ramp up is now controlled by a moving towards a modulating controller as opposed to a fast switching on/off style controller. This makes the power delivery very smooth, the ramp up is very smooth.  This behavior is noticeable throughout the operation of the motor - and just blows away the feel of not just the performance of the older controller, but it crushes any competing product out there. Instantaneous assist exactly when you need it The image above illustrates the Archon X1 torque compared to stock controller, and higher power variants.     Whoa, we did it. But there's more!   As a result of moving to the new modulating controller, we were able to gain nearly 20% - as in some cases as high as 25% efficiency in the motor. So as an example, all things remaining the same, a battery pack like ours - that gives around 45miles range, can now give you up anywhere between 50-60 mile range. This is huge in terms of your daily driver / commuter use case. This increased efficiency makes it easier to do longer distance and somewhat reduces range anxiety. The same pack should last you longer.     The image above illustrates the Archon X1  assist ramp up compared to stock controller and higher power controller variants.    Oh... we are not done yet! Now that we have the efficiency out of the way. The other big thing is about extra power. Well we can now provide you with a motor that can do up to 3000W. The nominal will be 52V with 45A pack- that’s ~2300watts nominal power.  The motor  can burst up to 3000W with no issues (with a 60A burst current). The theoretical max of the motor  is much higher… of course. There is a lot of head room on the overall wattage, but at that point, it is a trade off on parts wear and tear.   Smooth Assist, up to 3000W The image above illustrates the Archon X1  assist ramp up compared to stock controller and higher power controller variants. All this goodness, coming your way in May this year! (Assuming no big disruptions to global supply chain due to the COVID-19. Hopefully you all are staying safe).    Read more about what it means for our bikes!

                  I got 400 miles out of the stock chain

                    Finally, some hope on the horizon. I know there are a lot of people that ride the Bafang mid drives and think they’re fantastic because they have more power than the Bosch, Yamaha, etc., etc. but in reality the Bafang controllers are very crude and inefficient I was hoping somebody would step up and provide an alternative, maybe this is the beginning of a beautiful relationship.

                      That page says it was made for Ultra. While we do sell bikes with ultra, X1 uses bafang m600, not bafang ultra.

                        Does Luna have any plans to address the problems with the M600?

                          The support team in conjunction with customer feedback created a document that is several pages of customer feedback and recommended changes. We always do our due diligence. What is next is up to Eric, I don't have that kind of information, you would have to reach out to him directly if you want to ask about it.

                            Will be interesting to see if the controller is actually any better in real-world use. I mean is anybody really going to detect a 4000 per second sample rate vs. 9000 samples per second?? Looks to me the biggest difference is that the Archon has a smoothing program to even out torque application as Pedal assist oscillates due to the mechanics of pedaling a crank. If it offers some range increase then great. But cost/benefit will have to be determined. In my highly mechanical career and racing hobbies I've had to sort thru and test many efficiency claims. A lot of times it's just clever graphs and claimed advantages that while true, may not really make a real world difference in use.

                              Im trying to remove the stock chainring and replace it with a 40 tooth ring. Does the stock ring slid off after removing the bokrs or do I have to remove the 4 pronged thing its mounted to. If so it looks like I have to bolt the chainring back onto the bike and use the bottom bracket tool ?

                                Did you ever figure this out? I also am trying to upgrade to a 40T ring, but the 32T does not simply slide off. I figured I would look at pulling the cranks tomorrow but would rather not if there was some trick I was missing.

                              The stock chain ring comes off without removing anything else. You just have to rotate it until you find the spot where it comes off
