I see noone mention the Segway flaw in real world use - if either wheel loses traction for a moment, the device will spin and dump the rider on the ground. They're laughably bad and uncomfortable to ride compared to a regular pushbike, let alone eBikes.
Scooters are a smaller form factor, but bikes should be the real personal transport winner.
