The infrastructure is not a problem at all. Just use the one you have. If it can serve traffic demand using cars, it can serve ten times the same traffic demand using bikes (slightly less when using cargo bikes). Stop the segregation fantasy where drivers are allowed to get away with pretending that all roads default to limited access. They don't. Roads where first built for walking, then for walking and various form of animal transportation, then for walking, animal and cycling. When cars entered the picture, all the other forms of road use technically did not go away, outside of the small set of limited access roads that came up a few decades later.
