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).
