This build is kind of similar and this guy is one of the smartest guy I've seen on EV forum. He is using his bike way harder than me (using 12kw EVERYDAY) since 20.000km now.
He know is bike, I know mine. If you use it as it should there is limited risk.
About the top speed, you judging without knowing anything about the condition I tested it. And yes it was a one shot ride with FULL bike protections. I'm riding big bikes too and I know too well how you feel when something goes wrong.
Everyday I see biker taking way more risk than I am. I'm decelerating way before potential danger (road crossing, etc).
The only "dangerous" thing I do on a regular ride is one wheelie just in front of my house. Yes it is dangerous, but it is my choice.
It is amazing how you are judging thinks without knowing anything about me, the usage or even the bike. Come and test the bike, I'm sure you would change your mind.
Anyway I'm not here to argue. I don't even know why I'm answering you. You just proove you don't know what you are talking about
And please don't insult me...
