[Monkey Tennis]

Hi, I've just been offered this for 15 quid,he knows nothing about it watt etc, it's a long way from my home so would have to courier so weight I can't find out, does anyone think it's worthwhile, I'm very tempted at that price, there's a pair but I only want the one

Imho no one but a thief who knows nothing about ebikes would cut a motor wire like that

He's a scrap man, so God only knows,I'm new to all this, I'm not up for buying stolen goods it's just cheap I thought, is it a big hassle if it's cut? I didn't even notice that,I literally know not much at all yet about making one

It's very short to try and connect 3 wires let alone 8 or 9 if sensored.
For £15 it's worth a try, the tyre and and spoked rim are about 40- 50 quid to buy. Although tricky you should be able to rewire with a new motor cable if you have the patience, the worse part is feeding the cable through the hollow axle . A good lube with spread from the fridge will make the cable and inner axle slot super slippy for it to be pulled through.

I have the patience, thank you very much for your help.

I think you've got just enough to splice on a motor cable. You need to add on the cost of the cable and some shrink sleeve of different sizes. is it a front or a rear motor?

Shipping weight will be around 5 - 6 kg with the packaging.

I've cut several motor cables and spliced them to use round 9 pin connectors. THere will be three heavy phase wires for sure, and possibly 5 or 6 thin wires. The latter are easy to butt splice. The heavy wires can get unwieldy. Some people lay then side by side, and wrap thin wire around the joint. That's hard, and I often thought .. if only I had a copper tube for a solder form.

Then I found them inside your crimp connectors. I wouldn't use a crimp, but the little tube inside makes for an excellent form. Push both wires in, fill with solder, and cover with shrink wrap.

That's a great tip Harry .
