I asked them about guarantees as well. In a few days they will have an updated website with an online store and the warranty will be for two years! Supposedly, they will have 3 new specifications available: Economy, Intermediate and Pro (M600 & M500)
Maybe someone in Europe bought exclusivity? ;) Luna Cycle has purchased exclusivity for the old frames (E09) in US and Canada. Maybe someone in Europe bought exclusivity.

They also sell motors M500/M600, dengfu battery and frames. The price is similar and they have a lot in stock.
They can uptade motor software and change usseles PAS 1-3. It is a good option for Bafang motors users.
