Thanks for the tip, that did work however when I came to trying to rewire the PAS to match what the controller was expecting I struggled, so instead of buying tools to re-crimp the cables and make a new connector I decided to just replace the sensor. I bought this one from Amazon, but I think some of the magnets are installed backwards because it now detects pedalling in both directions and only detects intermittently. Is this product likely faulty or are the magnets supposed to alternate between N and S facing the sensor? Putting the old 5 magnet disc back on only works in one direction but you have to pedal quite fast for the bike to go at any decent rate, probably because it's expecting 12 magnets rather than 5 (I have set the controller to 5 expect 5 magnets and set the sensitivity to the highest level) New Speed Sensor Electric Bicycle Pedal PAS 12 Magnets E-bike System Assist https://amzn.eu/d/9Jgz9yN

Good morning, I have an update from further testing yesterday. I did test with a throttle but got the same results. I think I have now worked out why though, and worked out why the green wire didn't do anything; I had set the speed limit to 25 thinking that it was in kmph, but it turns out it's a percentage (a percentage of what exactly I'm not sure). Changing that back to 100 and sure enough the green wire makes the motor spin as described now. The 'number of speed magnets' setting might also have had something to do with it as I reduced that from the default of 80, but I'm not sure yet; more testing required after work today. So I got the motor working on pedal assist last night, however it only runs when pedalling backwards. Hopefully I just need to swap some cables around to get it running the right way, but all will become apparent later today. I feel like I'm within touching distance of having this working now!

I tried to do it but it didn't seem to behave as I expected. If I interpreted the manual correctly, the motor should spin / try to spin when you connect the self-learning lead together, if it doesn't work or spins in the wrong direction, unplug and plug it back in again. Repeat until it spins in the right direction. Is that right or am I misunderstanding / missing something? It didn't do anything when plugging and unplugging the self learning cable

Hello All I bought this controller / display combo from Amazon to replace the controller that had died in my pre-built ebike (E-life Voyage): https://www.amazon.co.uk/dp/B07JVJ6XQF?psc=1&ref=ppx_yo2ov_dt_b_product_details The controller can drive the motor on walking mode, detecting the speed correctly, and it detects when the brakes are applied too. However, whenever I connect the PAS I get a little exclamation mark icon appear on the right side of the display (not to be confused with the brake icon which is at the top) which I believe means communication error (see photo). Does anyone know why I might be getting this / how to resolve it please as I'm completely stuck? Could it be as simple as an incompatibility with the PAS? Thanks in advance.

Hey all I want to replace the controller on my 36V 250W ebike, but I don't know what to get; there are a few options on Amazon, but they all seem pretty poorly rated. Therefore, can anyone recommend a suitable replacement please? I've provided some pictures below of my current controller and writing. The reason I want to replace it is this one seems to be limited to 13mph, and I can't see a way of programming it with a higher limit. I did try an ST Link V2, but I couldn't even get Comms with the controller. I only want to stay within legal limits so I'm not looking to remove the limit entirely. As always, thanks in advance!

Here's some images of the wiring: It all looks very nondescript to me. There's also 3 unused cables on the controller, but if I'm to replace it, I doubt that these are relevant. All 3 look like this: The only information on the motor itself is what I assume is a serial number, because a Google search for it returns no results.

I did think about doing that. Is there anything I need to be aware of in terms of compatibility other than voltage? I can't see any identifiable markings on the motor so I don't know much about it other than it being 250W 36V. The main reason I want to change anything on this bike is because it is limited to 13mph; I read on the German version of this site that LiShui controllers limit speed to 13mph unless they have a digital display, but if that's not possible with the controller that I have then I'll have to swap the controller

Hi all As the title suggests I'm looking to upgrade the display for my ebike. It currently has what I believe to be a Kingmeter 790 with a none-waterproof connector such as the one pictured below. I understand that the controller is a LiShui controller as pictured below I believe that this is the connector for the display, though I could be wrong. I don't know how to determine which displays will be compatible, so I'm wondering if anyone would be able to advise, please? Thanks in advance!

I think I'm going to have to do this to both of my bikes. The motor on the theoretically less powerful 24V one will assist you up to a higher speed then the 36V one which is counter intuitive and annoying, but neither of them can do much over 15.5mph regardless of how much pedaling you do without the wind behind you and going down hill. When I'm committing to work on 40 roads, 15.5mph feels too slow, and 12/13mph is just painfully slow

This was pretty much my thinking, what I'm not sure about is whether there's anything I can do about it. Any thoughts?

The speed with a fully charged battery is 12, 13mph at a push. The reason I put the multimeter across it at 75% is because I had just got back from a ride where I'd confirmed that it wasn't going as fast as it should, and my first thought was that the battery was probably at fault, but it seemed to be outputting the right voltage, at least it was without a load on it. I'm hoping it's not the battery because replacing that will cost more than I paid for either of my ebikes

It does feel as though it might be dialing back the assistance early. The controller has a programming port as pictured here, apparently I can program it using something called an ST link V2, but that might be a little out of my depth since I can't find a lot of information on what software to use or how to do it. Alternatively I was wondering if a different display might work with it because I know some let you change settings in the display. The only identifying marks on the current controller are "790". Someone told me that it's a king meter but I wouldn't know how to check this. So I guess the question is, how would I know if a different display would work with this controller? Failing all that I was going to swap the controller with one that already has a display

Hey all, I'm new here so apologies in advance if I break any rules. I have recently bought a 2nd hand ebike and as the title says, it won't go full speed (15.5mph) with the assistance of the motor, topping out at about 12 or 13mph (according to GPS speed on my phone). I have a 24V bike too and it's not even as fast as that, so something's definitely not right. Mechanically everything is fine. The bike is a no-thrills 36V elife voyage. I've put a multimeter across the battery and it reads 38V with about 75% charge, so I assume that's about normal. The controller is as pictured, a G3M20211-1592-16. Does anyone know what the issue could be please? Other than just replacing parts to see what fixes it, I'm all out of ideas. Thanks
