I wonder how many internal combustion engined vehicles caught fire last year compared to cycles I imagine many many more but that's not newsworthy so cycles get the headlines, having said that if I owned one I wouldn't charge the battery inside the house just to be on the safe side.So you go green by buying a bike so you don't use your ca, you charge it with leccy generated in a coal powered power station then it pollutes the atmosphere with deadly toxins while you watch your wallet cry, yep this is the way forward
