I found this forum yesterday after I brought a brand new Moustache Samedi 27 Xroad FS 6 bike (sorry it's not an MTB, but for me, this forum is relevant). I searched for "Bosch eBike Flow Error 110000" and up popped EMTB Forums article on the topic. Really, aside from Bosch's website, there was nowhere else I found that addressed the issue. So anyway, hi! I'm here to share my pain today. Tomorrow I hope things swing the other way.
