I have recently purchased the Giant FastRoad E+1 Pro 2020 & all is good apart from an annoying noise which seems to be coming from the battery area, specifically the outer casing (I think) knocking against the frame, when hitting any bumps (there are plenty on our roads) on my road commute. When off the bike & checking over the battery area, there is a little bit of play when pressing the top of the casing, where the top part locks. The noise doesn’t make any noise when stationary & bounced up & down. The question I am asking as an ebike newbie, is this normal for ebikes to make this sound, or could the casing be faulty?
