Probably need two in case multiple emergency vehicles need to be on the scene. Imagine a bombing - you need ambulances, fire trucks, police, etc. That’s easy with huge car-based infrastructure but a bike-city seems complicated.
Unless you just build huge roads everywhere despite the lack of cars, which would be sad.

Fine, two. Two-lane, no parking roads are still only a third of the size of four-lane roads with parking on both sides.
Eliminating parking space for cars would be huge.
Might be able to cheat a little with the gravel shoulder, so it’s “two lanes” but only if vehicles on the left and right dirve half-off the road.
