Julet wiring uses a standard wire layout so any device with a Green julet will marry up the wire order correctly, the issue is compatibility with programming/software with your controller so is why the controller brand needs to be known.

Oxygen are in Rotherham. They used the same display on some of their bikes. If you ask nicely and can get your bike there, they might let you try one of theirs if they have one. A C500 might also work, but you'd have to try it. They might still have one of those from earlier bikes.

Does this sticker help?

Thank you for that info I will pass onto hubby!

The hub is Shengyi brand but it doesn't help with the controller brand or whether just any Bigstone lcd would be compatible.

I'm pretty sure that all Bigstone LCDs have the same protocols. The only thing with this one is that it has the three power levels as well as the 6 PAS levels. The C500 has that too. These LCDs are used on several bikes, but some (those with Das Kit electrics, like NCM) have reversed connectors and custome software. The Oygen bikes before the latest version used just the standard software.

Bafang systems use them a lot, if the protocols are the same then it might work, though tbh for the price of some of them it would be nearly just as cheap to swap out for a KT system.

If it were my bike, I'd swap the controller and LCD for KTsinewave controller and LCD3, which is a much easier to use control system than those C600Es. The C600Es have three levels of power, but you have to pre-select the one you want (eco, normal, power) before you set off. It can be done during the ride, but it's a bit awkward. In fact most owners don't even know about those. Instead, they use the 6 PAS levels. The other weird part about the control system is that the max throttle speed is fixed according to the PAS level, so can't override it, which makes it a bit pointless. Cost of the KT conversion is around £80 - probably the same cost as the C600E LCD or less.
