I'd never heard of them till now, thanks.

thelarkbox, thank you for the input and suggestions. The photo is of the magnetic ring which houses the magnets, I held iron nails close to them and there was attraction to each of them so l assume them to be magnetic. It snaps into place inside the sensor with the led blinking light. Its a...

Thank you thelarkbox, i'm working on the loss of magnetism from one or some of them. I've tried the smallest magnets l can find around the house and i can get them to stick at all 7 of them on the disk. I still have no idea how the 7 i've got correlates to it being a 12 pulse sensor?? I've also...

Nealh, thanks for the suggestions re slipping etc I've had a busy morning trying to understand what the heck is going on. My wife has an almost identical NCM bike so without asking (i'll be in trouble) l swapped just the magnetic disk from hers and hey presto my bike now works perfectly!! I...

Thats an interesting idea, Its only from your posts and looking online i've realised P12L means 12 magnets and left hand fitting. i've taken a photo of the magnetic disc and it shows what i presume are 7 magnets?? I've no idea how it relates to being a 12 magnet disc. There are 12 slots do you...

saneagle, thanks for that. I had a look this morning inside the box under the downtube that the wires go to. Its an awful looking thing full of circuitboards and connections then filled with some kind of resin i presume to give it weatherproofing. i have my doubts wheter i'd be able to get the...

Thanks for speedy responses, info and tips.

Thanks for that i'll try tomorrow. I checked the fit of the magnetic disk to sensor and it seemed good without any play and the whole lot to the bottom bracket seemed sound. If nothing else i'm learning more about the bike thanks to you.

Its alive, it blinks red! I presume that happens each time a magnet passes the sensor. The fit of the magnetic disk is good but i've put a blob of Sticks like sh*t on it and the axel just in case it turns when it shouldn't. Thanks again.

Thank you, i'm off to a darkened garage to see if l can see the red led blinking.

Its a separate two piece Magnet disc and sensor. I used a crank extractor to take off the crank and was able to split both parts of it. It seems in perfect condition with no signs of wear. I've yet to look inside where the wired connection goes to. I might try replacing it with a new one or is...

Thanks for that, i've just been out trying to work out which it might be. Its the external one on the left of the bottom bracket. If l use a lower gear to allow me to turn the cranks faster without gaining speed the power comes in shorter pulses. Turning them slowly gives longer pulses . The...

Hi, we're new to this forum and i'm asking for some help please. I have an NCM Moscow Plus 48v which although 4 yrs old has just 90 miles on it. last time out it behaved oddly. The power now only comes in pulses every 1 second when i'm cycling which makes it tricky to make any progress. It does...

Hi folks, wife and i bought NCM ebikes to get out n about now we've retired. We live at top of a hill so seem ideal to go electric after years of lumbering up the hill or resorting to pushing!
