After several punctures I adopted the system highlighted above in the images for my ebike and I find it excellent, I hope not to puncture anymore.
I found it here (ulmarii ciclista who was very professional and generous with advice) a similar model is also present here.
NOTE: The inflation pressure must be between 1.5 and 1.8 Bar.
Here there is a video, in Italian language, that explain how to use the spray repairs tires with the various valves found on bicycles.
Remember to completely unscrew the valve in the SV models (or French version), see video from minute 1:35
