The EWAVE Jetboard from China is an electric surfboard similar to the Jetsurf models from Czech Republic.
Ewave tried to bring out a cheaper Jetboard with more functionality. For example one idea was to offer an electric hydrofoil kit. The plan was that the user can exchange the jet drive with an eFoil kit (mast plus propeller and wings).
So far only prototypes were shown and the eFoil kit seems still not available. More about Ewave in our blog article Ewave Jetboard from China.
The Ewave Jetboards cost 10.000 to 14.000 EUR incl. 19% VAT depending on the model.
Basically yes. eSurfboards are classified as water motorcycles (jet skis) in Germany by the Wasserstraßenschifffahrtsamt (WSA) and must carry a license plate as soon as they have more than 2.21 kW (3 hp) of power. Other rules may apply to local waters. For example, eSurfboards are not allowed on Bavarian lakes and Lake Constance. In Austria the rules are not clear and in Switzerland motorized surfboards are not allowed. You can find more details here.
Ewave Jetboards must be registered as water motorcycles (Jetski) from a power of 2,21 kW (3HP) and must carry a license plate. The registration takes place at a waterways shipping office (WSA).
