We recently purchased a Bagi B10 e-bike and love the bike, but the display of the charge remaining in the battery is not working properly. The display shows 5 bars when full, but it constantly moves to 4, back to 5, back to 4.... Then it will move from 5 to 3, back to 4, etc. while riding. then as battery drops in charge, it moves from 4 to 3 to 2, back to 3, and then disappeared, then back to 3, etc. Is anyone else having this issue? Does anyone have a Bagi B10 that smoothly changes to 5 to 4 to 3 to 2 to 1 as battery charge reduces?
