Look at the cable coming from the motor. Is there a white wire amongst the others? That's the speed signal wire.

Mine doesn't. BBC again. Say no more!

Remember a couple of years ago, when the NHS got hacked because they were still using Windows XP!

9 times out of ten, with your crappy Swytch system, problems like what you describe come from that stupid multi-pin connector. Check that the spring blades each side of each slot are still giving enough tension and that none are burnt. Other motor connection problems would also give the symptoms...

What a load of ball-cocks. The statement in the first link isn't verified by the data in the second one. Then we have 80% of IT money is spent on maintaining legacy systems. I'm no expert, but that might be because 80% of systems are legacy systems! You would find the same age distribution for...

There's a spare white wite shown at 0:32, which looks like an unconnected speed sensor wire. You can check whether you have a speed sensor in the motor by measuring the voltage on it while you turn the motor BACKWARDS. If the speed sensor is working, the voltage will either blip up to 5v once...

The answer is no. Every single ebike can be adjusted using some method or other. Use a KT controller, put a password in it, then nobody can see the settings, let alone change anything. Pretend you don't know the password in the extremely unlikely event that anybody else knows your LCD and how...

What connector joins the motor cable to the controller? Can you show us the video? We can probably help more than the guy from Aliexpress, who is most likely a box shifter without any clue how the stuff works.

The whole point is that those records did exist and were active. Who is responsible for the integrity of the database? Who audits it? Why didn't they see it? Why didn't they fix it. When I worked in industry, I was responsible for many databases, either inherited or self-made. With the...

Choose a rim that looks similar to the old one. Look at the photo and judge how deep the well in the rim is. Some are very deep and some are very shallow. If you get one that at least looks equally deep, you have a chance of re-using the spokes. Alternatively, measure the internal diameter of...

I have one of these. It can do acceptable welds, but not very consistent. There's a bit of a knack to using it. You need to hold the probes at just the right pressure. https://www.amazon.co.uk/Battery-Portable-Machine-Adjustable-Soldering/dp/B0C6T8KZZF?th=1 It's cheaper from Aliexpress and...

W Who said they found any fraud? The distribution shows a significant number of errors. It has to be investigated before anybody can say whether there's any fraud and to what extent; however, in numbers that high, it would be reasonable to assume that there's some fraud contribution. What it...

That's nothing to do with what Elon's team found with the social security ages, since there was no clusters at 150 years old and the results more or less fitted a normal distribution curve.

P07 is the parameter for the number of magnets, so P07 =0, 1 or 6. If it's set to a high number, that would be why your speed reads zero.

Does your motor have a speed sensor in it? There's normally a setting in the LCD for the number of magnets in the speed sensor. Set it to zero if you don't have a speed sensor, otherwise 1 or 6 to get the correct speed. Zero will only show speed while the motor is turning.

T The £20 welders are a bit hit and miss, and there's a bit of a knack to using them. The more you pay, the better they are. Watch some YouTube video reviews to choose one; and if your strip isn't pre-slotted, cut slots with a pair of scissors to force the current through the strip, not across it.

It's for a low-power light. You should measure the voltage on it to get the correct type.

The only thing that matters is whether the bike you put it on becomes an EAPC or not, and the definition for that is given above in this thread. In reality, who has a private estate that they want to ride around on an ebike? It's guys like Simon Cowell, who soon learn to regret it, anyway...

As long as you keep a copy of the listing or any communications with the seller or manufacturer that confirms 250w, you should be OK. Don't show them any settings in your LCD. Just let them do any test they want to see if the motor assists over 15.5. mph. If your motor is a normal geared one...

I've seen a few. The worst is the multi-pin connectors to the LCD or LED control panels at either end of the cable, and battery connectors. I think the high voltage in there has something to do with it. A blob of silicone grease not only prevents that, but it also makes the connector much...
