Thank you all for your help - I finally had time to spruce up the bike. New chain, cassette, front cog, brake pads, brake and gear cables, headset, and saddle. Feels like a new bike! I worked out if I have the front brake connected to the cable, it cuts off and doesn't run on. So that's a work around without getting into electrics. Bike £80, Parts about £100 - not bad for a functioning ebike!

I've investigated the brakes. Took one apart, and checked it over. All seems very standard and not tampered with. Switches off and on. I also took apart the throttle. I can't see why that wouldn't work as all looks ok. Leads me to thinking, seeing as it's all original parts, perhaps the wiring has gone weird somewhere. I've had all the connectors apart and wiggled around. Doesn't change anything. If I could find the controller box online I'd take a punt at buying a new one, but I can;t find the model at all - nothing comes up. So maybe I'll leave this annoying brake issue and just ride it. I went 15 miles today no probs. Great bike, and will be even better once it has a service (a pretty major one!)

Thanks, I'll check tomorrow!

That's interesting - do you think both brakes could have gone wrong at once? And is there a fix,...?

I'll check, I have the tools - it does look like a cassette but I'll check. Yeah - 4000miles!!!

It seems like a solid bike indeed, and rides well. Considering how much use it looks to have had, it's held up well. I'll get a chain and cassette on order!

I think this is a good idea, to ride and be careful. It's an £80 quid bike. It goes well, and it's for short trips. So for now, I'll trundle on as is and see how it goes. Thanks for the help!

the other option is just to ride without brake cut off...

I have a multimeter. But am not sure how to check things and where to look. If I was to replace the controller, do you know which one will be a direct replacement? I cannot find a Luishi that has the same connections

these all come out of the controller

And finally, if this isn't too much info, when the throttle isn't plugged in I get error 34 which says faulty throttle (makes sense if it isn't plugged in) But when brakes and throttle plugged in, i get error 34 only whn I press the brakes to cut the motor https://pedegogo.zendesk.com/hc/en-us/article_attachments/360003271833/Dapu___Ananda_Error_Code_Troubleshooting_Chart.pdf Error codes read from this Not sure - maybe better to replace everything unless it's just likely to get a faulty cable somewhere?

Oh, and the top button on the display which on long hold turns the unit off and on. When pressed short press it turns lights off and on

I know the motor is 300w, or so says the PDF> But it just has the companies branding on it. The battery is 36v 15.6ah

Thanks AGS - I have located control box, and here are all the photos of what i found
