My friends wife has a Batribike it has 6 levels of power assist the next level is Auto which is throttle only there was an intermittent fault early on where it would skip the Auto mode and just go to level 1, this has become the norm now where it wont select Auto mode. Batribike have suggested that it may be a loose wire or bad connection etc. I have my doubts, so I would be happy to hear you thoughts on this. John
