My BBS01 conversion

[Sylvester]

Just to close this bit out, it was the hydraulic brake sensors that were faulty. It seems an early batch had a few issues. Eclipse Bikes (who've been great) took my motor back and were able to replicate the issue with their early batch of sensors. When they used a more recent batch it worked fine. The motor is now installed together with brake sensors and it works well.

So quite likely you and I both had sensors from the same dodgy batch - you will recall that I also bought my sensors via Eclipse.

Would confirm the comment about the faulty batch of hydraulic sensors I had some from eclipse in august 2014 but only got round to trying them in febuary this year on a bike I just built for my girlfriend.They kept showing error code and shutting down the display, I contacted eclipse about the problem and they sent me a new pair of replacement sensors which work perfectly.
They are quite sensitive and need to be aligned as shown in the photo eclipse sent me, the magnet needs to line up with the corner of sensor by the tab, anywhere else and mine did not work. (Eclipse pic below),

I fitted Shimano slx brakes which she finds much nicer to use than the BB7 she had before, I must say I like them as well and will soon be converting my bike to a set of Shimano Zee brakes.
