Bafang approved online Sellers
there were some concerns here earlier
Bafang had replied to an yearly concern with this reply:
"These are old product names and many are available on the market where importers may have bulk purchased in the past, but Bafang does not sell drive systems direct nor advise DIY projects using them. The new models will benefit from the extra years of product development invested into them. Always fully investigate any seller, and product specs and provenance yourself before purchase."
