Sorry But that helmet does not appear to meet the relevant standard (ECE 22.05) use on a moped/motorcycle. There are light open face legal helmets but they are more substantial than theseTrue in law Miles, but in fact wearing an open-face full cycling helmet of the Casco type for example would pass muster. This type of helmet is very popular in Australia and New Zealand so must be practical even in quite hot conditions, especially on an e-bike.
I can't see the police stopping anyone riding reasonably and wearing one of these, they have far more to occupy themselves these days with ANPR and the large number of uninsured, unlicenced drivers operating without valid MOT certificates.
