Granted, if you are riding with someone on an e-bike, it can just repeatedly detect them through your ride.
The way mine works is that it will only notify you when a vehicle is moving at a speed that can overtake you. If an ebike (or any vehicle) is moving behind you at the same speed, you won’t be constantly alerted, but the “dot” representing them on your screen will show up so you know they are behind you.
You will be notified when a vehicle is no longer behind/beside you.
But yes, if you are riding with people behind you, and they are constantly fluctuating their speed, you will be alerted multiple times. Not a bad thing (you can mute the alerts), but it can be annoying if you ride in crowded city bike paths. A radar won’t add much value in that context, so I would just keep it on to act as a rear taillight.
