Ah, what he mentioned were e-bikes, but those are not really on the fancy side. Search for 饿了么 scooter or 美团 scooter. They do food and grocery deliveries mostly. For private use, Niu scooters are the most popular in terms of design, but a ton of cheap stuff exists. Couldn't tell you about the brands, they are all very generic.

Electric motorbikes exist, but require a special license and are banned in most downtown areas, so they aren't really common. One brand I'm aware of is called Dayi Motors, they recently got certified for the European market, so chances are that those would become available elsewhere as well.
