So I'm building a dual drive E-MTB and I'm not sure if I use chain/sprokets or belt/pulley for drive. Here are some of the pros that I could think of each one:
- Less prone to fall off
- Less maintenance ?
- Lighter ?
- Less sensitive to misalignment
- No slip
- More resistant to rocks, debris
Now the biggest cons of belt drive is little rocks getting in the pulley, which can jam the drive or damage the pulley and belt. That's my biggest concern on belt drives. I have had a few rocks stuck in my e-longboard belt drive, but maybe that's because the pulley is very close to the floor. But on the other hand, I'll ride on dirt, grass, gravel roads on an E-MTB, not just on asphalt like a longboard.
I learned to hate chain drives with my current E-MTB, I still have a hard time trying to properly align the chain. I have to admit it has some design mistakes
, but I think it would not happen with a belt drive.
So what you guys think?
