This 2021 catalogue (probably produced in late 2020) does not include any hint of the Wheel Top EDS electronic derailleur system.

However it does include some useful information about Wheel Top itself. It lists a number of related companies on the rear cover including 'Lanxi Super Smart Cloud Sports Science and Technology Co. Ltd.'. It's a pity that they couldn't find space for the words 'Blockchain', 'Vegan', 'Qanon' or perhaps 'Elon' in their, search-term-laden, company name.
