It's only a possibility that it's anything to do with the sensor, but checking that area will also give you the opportunity to check the tightness of the final drive screws. One of mine was loose.
Seen a few strip down video's, but haven't seen this PAS sensor disc yet on any BBS01/02. Can you give us a clue/Pics where this is located?
That's interesting so, for clarity , does throttle still work silky smooth whislt PAS is juddeery over 600w?
Now you're just being silly, of course not, but the settings really are fine, they were good for a year before juddering started. Interesting that it started after a long layoff over the winter, although my garage is dry as a bone, no moisture, probably only drifted under 0 degrees a few times. Beginning to think controller needs replacing, fairly sure it's the old type with the bad components anyway, how can you tell?
I had to reset them them earlier today anyway, the Eggrider app is so buggy at this first release it wrote current and speed assist settings in series rather than parallel resulting in every even assist being correct and every odd assist (1,3,5,7,9) being 100%, damn strange test ride I can tell you. Used the good ole fashioned bafangconfigtool to write back 11,100,22,100.......99,100. Test ride fine but still juddering at high current in PAS only.
Apologies for the late reply @robwalley
Ta, Eclipse guys sent the same picture and stated they knew of examples of this fault and symtons. Who stock this?
Got the dual kit disc and circuit from GreenBikeKit for <$25. Arrived in 12 days. Looks good - now to fit.........
