I have a friend in Knottingley West Yorkshire who needs help with a Zero X electric motorbike. He says "some of the cells are not charging" He has changed all the electronic parts trying to fix the bike his self with out any joy. Is there anyone out there that can help him with this awesome bike ? I am down in Somerset and its too far for me. The technology is not that complicated.I think It has a brushed motor and Potentiometer throttle, High end speed controller but the battery must be something really special to provide the performance of this machine. I have thought of sending him to a mobiltity scooter repair shop. Can anyone help him ? He can pay the right man.
