Anyone know how, if it's possible, to get an older version of the M600 FC 3.2 controller? One that will run 14.6 or 46.8, for example? Thanks.

So interestingly, I looked some more, changing gears does end up cutting out the motor but for an extremely brief time. The motor does not even entirely ramp down before it powers back up. Not enough to be at all effective. I have the same sensor on a Bafang Ultra and while the green light on it...

Hi have an M600 with a shift sensor. It blinks red when idle and when I shift is blinks green. Even though it seems to detect the shift, the motor does not stop. I was thinking of changing the shift sensor or trying to clean it but not sure that makes sense given it already blinks green when the...

Excellent! Sounds reasonable. KT is Kunteng. For what it's worth, most of those settings won't really screw up too much. There's the current limit you'll want to set at a reasonable value also the throttle may not work the way you want it to out of the box but there's a handful of settings for...

Oh one other thing to look for is check that the controller is sinewave, and not squarewave. Maybe that's what it was that I found, the 25 was square? I'm not totally sure, but sinewave is what I think you want. Potted just means the electronic are covered in a silicone to keep water from...

If I remember correctly, the 25a didn't have the julet plugs and the 22a did? But yeah if the 25a has what you're looking for and it's not any bigger, definitely a why not in my book. I did the 22a and reduced the max output for the same reason. About the display, if you mean it doesn't have the...

Yeah, fyi in case you haven't run into this yet, those light plugs only support very very low wattage lights. I forget the actual limit. So if you plug in something with any real brightness, it might fry part of the board. I instead used some of those vampire clips, or whatever they're called to...

I didn't have to use the box. I did as added protection and I felt it made it look a bit more finished. The box there fit the controller pretty well so it did not add to much bulk. The aluminum case is technically waterproof, but it's not potted so there is just a seal wedged between the box and...

Got it. That makes sense. Yeah, because when I soldered the new connectors on I remember it only having two wires for the brake. For what it's worth this is what I ended up with: https://www.aliexpress.us/item/2251832818572671.html The controller and the 1-4 cable.

Here's some pictures that might help. The brake is two pin. What you might be thinking is the third pin is just a slot for the connector.

I didn't have to replace the brakes. I'll take a look in a bit and post back. I thought the brakes on the KT controller were still two pin and the throttle was 3. I can send you I bought on Alibaba if that helps. Not sure all the sellers are still selling the same stuff at this point but it...

Yeah, if you find a way to configure the individual PAS levels, that would be a huge win. They're sort of configurable, as a whole, by adjusting the max current which basically seems to compress or expand a power level shape curve... also by altering the overall assist strength (ie eco, normal...

Yeah, the wires coming out of that controller look like what I have. They could have switched it up on your bike, but for the Moscow the brake connectors were a bit different. The throttle connector is the same, but male and females are reversed from the KT (and a lot of other controllers). I...

Yeah just plugged it in and worked fine. The only issue I've run into with the conversion is I can't get it to go over about 24 or 25mph, but that's been good enough for me so I haven't really looked into it much. There's a few settings that need to be set to tell the controller some attributes...

These are the main parts I used: the 155x80x45 box here: https://www.aliexpress.us/item/3256802973651515.html The controller here with the 1-4 cable (cant buy from this link anymore, but its the one I used) https://www.aliexpress.us/item/2251832818572671.html And the KT LCD 8H display. FYI...

I did this conversion last winter. One of the main reasons was to get rid of that lag. Ended up working out pretty well. I was able to get the KT controller and box for it that fit it pretty snug and mounted it by where the old controller went so almost all of the new wiring was hidden...

I don't have much to contribute here, but Angular (not AngularJS) is not rubbish :) Carry on...

I'm a little confused as to whether or not you have a brake cutoff, but if you do, unplug it and see if the bike works. If it does, it's the brake cutoff that has an issue. As for the PAS disc, it looks like the shop has it aligned pretty straight but if it is not and the disc is different...

FYI figured I'd mention. Bike came with firmware version 46.8. A friend put 46.7 on about a week ago after I read it was good a firmware for the M600 when the bike is mostly used on road/rec paths (instead of mountain biking). So far I'd recommend 46.7 for road use. I'm finding it is better on...

yeah for sure. It's just kind of nice that there is a repo with a bunch of official and some unofficial tunes. I wish something like that was around for Ultra... a one stop shop for firmware of sorts. But yeah you'd have to spend a while testing out different tunes to figure out which one fits...
