After 10 miles' nothing fell off (4 yr old or otherwise) and all the electrics are fine.... just need to replace the oil rig grade cable ties with some more fit for purpose.... Oh, and convince BTN that they might actually have something to gain from a providing a soupçon of customer...

Update, 8fun Bafang BBS01 LCD C965 - W2849A_APT 800S-KEY01 The push button unit connected to the Bafang c965 lcd unit was very easy to open up, 5 small screws to open then 2 tiny screws to expose the PCB inside. Evidence of moisture ingress along with a sheared off soldered joint *the latter...

so basically off with the chainring, the sensor goes under the retaining ring refit retainer, fit centred magnetic disc (check it is working) - then refitting is the reverse of........

once I get the critical dimension I might well order one .... depends on the number or magnets too , I have 8 at the mo 10 might up the speed.....

can you send me a photo of what you did with it to sort out the mounting? I did think of fabricating the equivalent of the solid spacer that holds the front derailleur away from the frame, to hang on to the sensor.... or a big broom handle

might well have to resort to gluing the sensor down, I just feel that there should be a more professional option since the epoxy will inevitably fail if the sensor gets a clout away from the frame (as it inevitably will)...... there must be many people in a similar position to me,... my...
