Best eBike brands overall

Hey everyone!

I'm diving deep into planning my next custom eBike build, and it's got me thinking about the core components. When we talk "best eBike brands overall," especially for a custom project, are we thinking about the motor and battery manufacturers primarily, or the frame builders, or a combination? I'm aiming for a versatile hardtail that can handle some gnarly trails but also commute comfortably.

What brands do you guys consistently see delivering top-tier reliability, performance, and perhaps even good support for custom builders? I'm curious about everything from Bosch/Shimano/Bafang to smaller, more specialized names. Let's hear your thoughts!
