I would guess the Priority 600X adventure: https://www.prioritybicycles.com/products/600x

As far as I know, that's the only mountain bike sold with a pinion + belt drive stock.

Nicolai also manufactures mountain bikes with a Pinion gearbox and a Gates belt:

- FS SATURN 11 GPI https://en.nicolai-bicycles.com/bike/saturn-11-gpi-2023/

- FS SATURN 14 GPI https://en.nicolai-bicycles.com/bike/saturn-14-gpi/

Woah, that belt chain tensioner on the GPI... very nice solution to a common belt drive issue!

Thanks for the link, I'd never heard of these folks. Love seeing innovation like this in bicycles.
