folding electric scooters may be good forms of last-mile transit, but they can be a bit of a hassle to carry while on buses or trains. That's why a group of San Francisco and China-based entrepreneurs created Blizwheel ESkates. They work somewhat like the existing electric Rocketskates, although they fold flat and can be carried in a laptop-sized bag when not in use.

Each ESkate consists of a motorized wheel with a solid rubber tread, which a foot platform folds down from the inside of – that platform has three smaller unpowered stability wheels of its own. Users strap their feet in, wearing pretty much any type of shoe, then go.
