The battery is a standard part. Have a look on Aliexpress, where there areloads of sellers of exactly the battery you want. Search for "36v folding bike battery" or something like that.

Set your meter to check continuity (beep). There are three thick pins on the motor connector and 6 thin ones. Each thin one corresponds to one of the solder pads on the pcb: A, B, C, H, 5v and GND. Check that you have continuity from each of those pads to only one pin on the connector out of...

Not normally, the speed sensor only affects the speed display and sleep mode engaging every 5 minutes or whatever it's set to.

He took them by surprise, just like the Brexit vote. In both cases, they thought they had done enough, but in both cases they underestimated the normal people.

There wasn't really a need to do voter fraud in the USA before. This year will be different. Some are predicting civil war after the election.

I was have been an ardent follower from the beginning of his career until the first GP this year. I haven't even been bothered to look on Google to see what's going on. Politics should stay out of sport. As soon as they bring it in, I'm no longer interested.

As I said, no need to discuss any further until you get a meter.

You don't need to worry about that. I've never had to change that parameter from default. In the worst case, you speed display will be out a bit, so you can adjust until it matches your GPS.

The 260 rpm one will reach about 19 mph on the road with a charged up battery and the other one will be about 1 mph slower. Obviously, the one with the higher voltage will make 20% more power, so it'll hold on to it's speed better, but by the time you get to 20A, they'll both max out fairly...

Its a ShengYi 36v motor for a 26" wheel. the rest is the model number, production date and location. There aren't any motor specific settings that aren't obvious.

Measure it with a meter.

The Carrera Vulcan has a cassette motor. What's happened is that the cassette is not free-wheeling properly. Maybe some grass is caught between top gear and the frame or some dirt has accumulated somewhere, or it just needs oiling.

You can't just select 24v on the controller. All that does is change the low voltage cut-off point to protect the battery from over-discharge. You have to physically change the battery to a 24v one, then set the controller to match.

It might work with just a 24v battery then.

If you went down to 24v, you'd get half the speed. For that, you'd need a new battery and controller.

I found this that might be a direct replacement (2nd from left): https://www.aliexpress.com/item/4000932651223.html?spm=2114.12057483.0.0.7dbe19bcKZfLuR You still have the problem that your motor span out and twisted the wires. To blow anything, the wires must be damaged, so it's a waste of...

49e sensors are for throttles. You need SS41

Did you order exactly the one in the link i gave you, which clearly shows the pedal assist sensor and its connector?

A 15 amp controller can get you up to 20 mph on the flat, but it'll overheat if you keep it there. The 15A/7A means that it can run at 7A continuously. It will will give 15amps if asked, but it can only sustain that for a short time. I ran a double 328 rpm Q100 motor setup. Obviously, the two...
