Our 9 year old has an electric scooter. I didn’t really want to get it for him, because I’m an old school analog bike guy myself, but I have to admit it is convenient. It has around a 15 mile range and keeps up with a comfortable cycling pace, so my wife and I ride our commuter bikes and he cruises along next to us.

He also has a bike and he’s a pretty strong rider for a kid, but it’s still a bit much for him to keep up on longer trips, so the scooter helps there. I expect in a couple of years or so it will break or he will outgrow it, but by then he should have no trouble keeping up on his own bike.
