Every city has suburbs. Practically, every suburb has some mass transit line into or near a major city hub.

If cycling brings you happiness and is a significant part of your life, then move to a suburb. Ride your bike towards the major city hub. When you get to a bus or train line that can deliver you closest to your place of employment, stop and take the train or bus. Next, cycle the last leg into work.

Sounds feasible, but may not be applicable in your particular situation.

PS.

On the weekends, just cycle in the suburbs and rural areas.
