Then amazon pulled the plug on them

Then mark Cuban, the company making those kick push razer scooters, and I think somebody else aLL claim to own the official patent and gonna cease&desist all the other 'knockoffs'

Then a few cities in multiple countries banned them in public



They still out there tho.

Segway copied the design but with bigger wheels; if somebody can lock down the quality control issues to fix the battery fire problem, theyLL take over
