Hi I i have recently purchased a used Scott Genius Plus ebike. I have had a couple of people test ride it and I have ridden it once. I have now cleaned, oiled and adjusted the pressures and ready to go. However I cannot get the bike to switch on. The battery is fully charged but the digital control unit is blank. If I push the battery power level button I do get the eco word come up on the screen but this disappears once the button is released. I have replaced the two button batteries, held the power button down for 10 seconds but still nothing. Please can anyone help?
