eBike technology explained

Hey everyone!

Been lurking for a bit and finally decided to jump in. I'm really getting into the idea of a custom eBike build, maybe a hardtail mountain bike for some local trails and commuting. My biggest question mark right now is understanding the different motor technologies – hub vs. mid-drive, torque sensors vs. cadence sensors, etc.

For those of you who've built your own, what are the key things to know about these components? What did you prioritize for your build, and what's the real-world difference in feel and performance? I'm trying to wrap my head around the pros and cons beyond just the spec sheets.

Cheers!

Hey there! Awesome to hear you're diving into a custom build – that's half the fun! For a hardtail MTB used for trails and commuting, the motor choice is super important. I'd lean heavily towards a mid-drive motor with a torque sensor for that kind of riding; it feels much more like a natural bike, especially on trails where you want that responsive power delivery. Cadence sensors are fine for flat commuting, but a torque sensor really shines when you're climbing or navigating technical sections, giving you power based on how hard you're pedaling, not just if you're pedaling. Good luck with the build!
