Yeah, good roads are still required for bicycling.
Although, it would greatly reduce the frequency of maintenance events if it were only bicycles, since the lighter vehicles would be much less damaging. Then seasonal changes will remain the major factor for wear.
Maybe it would even change the kinds of materials we use in the roads, because you now have similar pressures, but over a much smaller surface area (overall lower forces).
Even a dry trail is pretty efficient on a bike
*As long as someone laid down pavement or keeps the trails maintained
Still by far the least amount of necessary infrastructure needed for any means of transit except walking.
Yeah but the comparison is with fishes and birds
As long as somebody laid down the rivers and the mountains, which took a couple billions yrs
