    S866 / Brain Power Motor Controller showing communication error with PAS

    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...

    S866 / Brain Power Motor Controller showing communication error with PAS

    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...

    S866 / Brain Power Motor Controller showing communication error with PAS

    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...

    S866 / Brain Power Motor Controller showing communication error with PAS

    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...

    Help! Replacement controller advice needed

    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...

    Upgrade display - what's compatible?

    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...

    Upgrade display - what's compatible?

    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...

    Upgrade display - what's compatible?

    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...

    Help! ebike won't reach full speed!

    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...

    Help! ebike won't reach full speed!

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

    Help! ebike won't reach full speed!

    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...

    Help! ebike won't reach full speed!

    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...

    Help! ebike won't reach full speed!

    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...
