Mentioned this original trouble before-bought an ex demo (or old stock?) Wayfarer folder few weeks ago and battery would not show all three green lights on top of battery after long charges-only two green-other red.Sent back for checking and now they sent new battery.It still does the same-two top lights green other by empty sign red.The charger was OK they said.Is this normal on these bikes? Quite happy with the bike apart from this.It is one of the old( twist and go )throttle bikes.
