That means that the interruption is between there and the charge socket. Check continuity (beep) between each of those two positions and the corresponding pin on the charge socket to find out which wire it is, then you need to follow along the wire to find where the interruption is - normally...

SYEBC in Rotherham might look at it for you. The guy in the workshop (Dale) is quite good. Your problem is almost certainly an interruption on one of the wires in the motor cable. In particular, look at any connectors between the motor and controller. If you have the 9-pin one about a foot from...

If you set the wheel size to 20", it might set the speed limit proportionally higher. Did you press and hold for 10 secs like i said above?

It can be any cable that carries 5v anywhere on the bike, like PAS cable or motor cable. While you have the controller open, connect the throttle switch connector (brown, yellow and green) and the battery. Switch on and measure the 5v on the PCB to see that it stays steady. that will confirm a...

Brushed motor electric bikes normally have lead batteries, which are completely different. They don't have any management or shut-off system. You can tell what you have by the weight. Lead batteries are bloody heavy,

Are they lead batteries or lithium?

Try this. Press and hold the set button (second from top) until the screen changes, then press and hold it for 10 seconds to see if it goes to another screen.

Sorry about your loss. I'm not going to say how for obvious reasons, but it's very easy to switch on the battery without an ignition key. Did you have any security other than that thin cable lock that can be cut with side-cutters?

There's no point in measuring cell voltages if you have zero volts on the charge socket You now need to measure the voltage between the points where the yellow wire is soldered to the PCB and the thick red is soldered to the cell pack, which might be at the other end of the battery...

It's simple. The system already measures the crank rotation speed. When the wheel speed sensor gives out the same rpm as the crank sensor for a period of time, it can give an error code.

That's completely wrong. The Labour and Conservative parties have no chance. The Brexit party will win.

I think you'll find the size OK. there's not really much to look out for because they're pretty well put together. like any bike, it depends how well they're looked after. The only common problem I know of is the speed sensor magnets coming unstuck in the motor. When it happens, the speed...

Almost certainly the batteries.

Your batteries are probably shagged. Can you tell us the entire history of the problem? How did it start?

If you want a throttle and under £1k, it'll have to be Ebay or Amazon. There should be plenty there. If you can find one that you like the look of, post details here and we'll check it out for you.

Use Google. It should take you directly to the controversy and biased press reports.

Sorry, I misunderstood you. There must be a short on the controller side somewhere. Look for anywhere the cable makes a tight turn or where a cable tie holds it too tight.

There must be a short circuit somewhere. disconnect the red, black and blue connector and measure the 5v again on the controller side. If it stays steady at 5V, a new throttle is probably the easiest option...

You can't do that. This is an open forum where anybody can discuss any relevant points in any thread. You opened the thread, but that doesn't mean that you own it. You have the right to delete your own posts, but IIRC there's a time limit on that. What did you think was going to happen when you...

The brown and yellow wires are the switch on the throttle, the green one on the same connector is battery voltage for the LED indicator lights. Red and black joined to orange aand black are the 5v wires. that leaves the blue to green is the throttle signal wire (1v to 4v). To measure the 5v...
