There are three reasons you probably don't need to worry about those checked devices.
First, ebikes have way larger batteries than mobile electronics. The first laptop that came up when searching for laptops with large batteries had 80 Wh. The smallest ebike battery that appears in the first article searching for "ebike battery capacity" is 400 Wh.
Second, these problems tend to occur in uncertified third-party knock-offs. Your Lenovo or HP or Apple laptop, or even your Shimano or Bosch ebike, are much, much less likely to fail than a cheap eBay or Amazon battery.
Finally, and possibly most importantly, you are at highest risk while charging, slightly less risk while in use, and lowest risk when off. A device switched off in an aeroplane cabin is about as safe as it can be.
