Thanks a lot guerney for finding that thread for me. Sounds exactly like my problem. Replacing the stator is not something I'm going to be up for with 3 small kids at my feet. I will ask my LBS but maybe it's time for a new system

Just inspected battery connections - look pristine, no suggestion of short circuit or intermittent connection there. However, during inspection I could hear a very quiet whirring noise from the motor. Then, on wheeling the bike backwards (engaging the motor with the cranks) it sprang into life...

Thanks for that. Awaiting reply from seller, and mentally preparing to protect the connectors on the next one in the manner you describe!

Interesting point re bullet connectors - yep I used them and yep they are crimped on. Having said that, I used plenty of insulation - heat shrink followed by plenty of self-amalgamating tape. Can't imagine an arc occurring there. One source of worry was the 6V lighting supply - I can't use this...

I installed the controller carefully but agree there are some rather vulnerable wires. Definitely closed without pinching and I don't think there was excessive flexion. The main question in my mind is: could another component in my system be responsible for trashing the controller? I don't want...

Thanks, I've contacted the seller and will see what transpires. Slightly tricky as they are in Germany... Gotta love Brexit. I'm not sure how I would go about testing all the other components but I have a multimeter! Are there any good sources of guidance online without having to draw on the...

Thanks for all comments. After several days drying out the system is still dead. Guerney - I have 5v between the cadence sensor pins as per your diagram - do you think this mean the controller isn't dead? I was going to contact the supplier to say it was, but am not sure how to diagnose. The...

Guerney - I believe they are Panasonic cells. Battery has been rock solid since purchase in 2017. The funny thing is, the previous failure happened in France in the warm and dry summer weather. So I wonder whether yesterday's wet conditions are a red herring. I'll remove the throttle as you...

Thanks for all comments. Battery voltage 37v. Charging to full before testing again. Display working normally. Sensor terminals reading 5v between black/red and black/white. Power briefly this morning on pressing throttle but no PAS and throttle stopped working now also. Any other ideas? This is...

Thanks, I'll test for a voltage at the speed sensor as you recommend. Yes I used the gasket and had no trouble getting it properly positioned

Hi all. Had a system failure earlier this year, thought due to failed controller. BBS01B 250w 36v. Symptoms were high pitched noise followed by intermittent power loss, followed swiftly by complete power loss. Had my LBS have a look who were confident it was the controller. Replaced...

Many thanks for this, I'll have a look on Endless sphere but I think it's a goer from what I've read so far

Hi all. My BBS 01b controller has died. I've received a replacement from an Amazon seller but, despite specifying 36V 250w they've sent me one labelled 48V 750w. Looks as though I'll end up paying return postage to Germany as the customer support hasn't been forthcoming, so just wondering...

I think in general it's best to own a sufficient number that one's wife is never quite sure how many are supposed to be propped up behind the sofa. Matt, sorry but I didn't find anyone doing mid drive kits on Cycle scheme. I think I'm just going to take the plunge with one of the Bafang kits...

Hi there Newbie and first time poster. I'm looking to buy a road-legal conversion kit for my Boardman hybrid. The small amount of research I've done so far has made me think a Bafang kit would be suitable, and easy to fit. Ideally I want to buy through a vendor affiliated with...
