Well I knew if I messed about a bit more with this PA disc and sensor, it would give me much more space on the BB spindle to make sure pedal crank arm goes all way on, which obvious due to the PA large disc, it could only go so far, actuially I do believe someone here did say try placing the PA sensor some where else so its not stopping the PA disc from going close to frame on BB spindle, well I do apologise to who ever that person was as it took a while very awkward but I have now managed to place PA sensor on seat post, as in images, and bingo PA disc is now fully on BB spindle no gaps behind it, so now there is much more space on the BB spindle to fit pedal crank arm. just got to tidy up the wires. I may need to adjust sensor position so its aligned with magnets on PA disc, tidy up wires. hopefully PA will still work ok

pedal help

Hi all I had fitted a while back a pedal assist disc to my pedal shaft. but only have now noticed, that the pedal arm now seems to wobble, reason being, is because the disc isnt flush to end of pedal shaft, but if you look at pictures, I cant have disc fully to back of pedal shaft as it needs...

If you'd tried that you wouldn't have messed up your crank arm.

The disc must not touch the frame tube, otherwise it won't rotate with the pedal

Well it is rotating fine, but I can bring it back a bit
