A drone can be shot down, a drone can malfunction and crash, a drone can be jammed or otherwise electronically interfered and crash, a drone can structurally fail due to quality control issues or previously unidentified damage from prior rough handling in a warzone and crash.

It’s a lot better if any of those happen to a eBike, than if it happens to a person who’s literally hanging below a drone flying at even just a hundred meters altitude.

Also a eBike can be folded into much more aerodynamics-friendly shape and size to maximize the drone’s range further, a human, not so much lol
