what happens when a bit of gravel gets between the drive cog and the belt?
The same as what happens on a conventional belt-drive bike.
Not quite the same unfortunately. On a conventional belt drive the belt is “free” to rise off the pulley (requires the belt to stretch) if a foreign object gets caught in the mesh.
In this case however, the friction of the system is generated by the belt being backed by the rigid rim of the wheel. For a bit of gravel to go through that will require the wheel or frame to deform out of the way to make a clearance……….
