Adventure 2: What speed do you all ride and what gear (PPE) do you use?

This thing easily goes 30mph and in another e-bike community they are freaking out about that saying I'm gonna get tire blowouts and all sorts of stuff. Idk why I'd worry about that driving it at its spec, I haven't hacked it or anything.

They also say I need full motorcycle gear. Overcautious or deserved?
