Hello! I'm new to electric bikes and thus to this forum. My fisrt Giant Lafree Twist lite was nicked and with insurance i have replaced it, second hand. This one does six miles then the light blinks, and it does about 6 miles with that blinking light before the motor stops. Do I need a new battery - and i riding it wrong? (there r no hills - its all London commuting. Since the battery takes its charge, should i be worrying about the electrics on the bike b4 replaing the battery? All this on eco mode. Its a wonderful experience, this bike, and i have discovered the world of canal paths within London - amazing life enhancer! any advice gratefully received. Bill x
