Best eBike brands overall

Hey everyone!

I've been lurking for a bit and thought I'd jump in with a question that's always on my mind, especially when I'm dreaming up my next project. When it comes to custom builds, what brands do you all think offer the best foundation or components to start with? I'm not necessarily talking about the best pre-built eBike, but rather which brands consistently deliver quality frames, motors, or batteries that are prime for customization, whether for a rugged commuter or a light trail explorer.

Are there any specific brands you swear by for their durability or ease of integration when you're piecing together your dream machine? I'm curious to hear your thoughts!
