Hi Im a new member and just bought my first electric bike Synergie mistral on opening box i was a bit perplexed to find that no instrutions had been added can anyone tell me if there is a manual of some sort and where i can get one allso i am a bit worried about the charging the battery being a lithium Ion ive been told you should charge these every time you have been out but do i have to charge this as soon as i get back or can it wait a few hours as i am on economy seven and charge most of my things through the night on a time switch
