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.
The roads are huge because of multiple lanes in two directions with street parking on the side. An ambulance only needs one lane.

Fine, two. Two-lane, no parking roads are still only a third of the size of four-lane roads with parking on both sides.
