just got this bike at auction, oh dear.... brand new in box, looked to be anyway, perfect for around five rides then cut out and won't go , can't switch lights on.. control will scrol through Eco sport turbo etc but no assist whatsoever , battery is showing five bars at switch on have tried removing battery and wiggling etc, same with slide in control panel on handle bars, recharging, etc, don't know what to do next? Any help appreciated, I'm in Wollongong NSW , I realise this is a uk site , but can't find any Oz forums as yet, cheers Jonny.
