Bicycle are not motor_vehicles.

Mountain Bikes would probably prefer 'tracks'.

Tagging for the render. Or the reverse - rendering for the mapper?

Mappers need to tag the truth, how it renders should not be a consideration for mappers.
That would be 'ideal', realism strikes and there is a need for rendering the truth is a way that rewards that truth.
