Hi,
I just discovered that the rather 'lumpy' power delivery on the pedelec system of my 905se is down to magnets having seemingly fallen out of the disc on the pedal crank. Is this a common problem? is it worth keeping a spare disc? - I don't know how much they cost, but since my bike is only 5 months old @ present I'm assuming they are covered under warranty (I haven't contacted ETS yet, where I bought the bike).
One question though: When I replace the disc, it looks like a simple job to put it back on the left crank, rather than the right, and to move the sensor to the left also. Will it work if I do this, or will it 'think' I am backpedalling and fail to energise the system? I'm not sure if the system senses direction of travel by measuring uneven gaps in the placement of magnets?
If it is possible to move the sensor system over to the left side, then I can fit a proper chainguard over the chain on the right - and - bingo oily trouser problem sorted!!
Incidentally if it does sense direction by measuring gaps between magnets, is it possible to obtain mirror image discs?
Cheers, Phil.
