Have you tried asking an AI agent such as Gemini?

I asked it for you this time, and it says that most modern e-bikes use Standard Blade Fuses (also known as ATO/ATC fuses). They are typically 30 Amp (Green) or 40 Amp (Orange). Some have a secondary for the charging port, 5A or 10M Mini Blade Fuse.

Yeah, that's really annoying.
There is usually one main fuse (about 30–40A) and one smaller charge fuse (about 5–10A). Just make sure they're the right type of blade and look for any markings first. Don't guess too high.

Normally they will be regular blade fuses (often mini/micro). Look at the battery pack label or controller specification and match the amp rating, which is normally around 20-30A on packs like this.

I too, have the U2 bike and the battery has 2 empty fuse holders. I also could not find support to answer my questions.
