this is not a google map type, it doesn't belong here

Google maps has TransitLayer and BicycleLayer classes, but not MapLayer class.

keeping one LayerManager, though, is a good idea, I just think that at the level of google apis, it should be separate since google keeps it separate

I really think that the google-maps-api-wrapper class should have separate methods for createTransitLayer, createBicycleLayer, createTrafficLayer since there is nothing in common between these, and it's bad practice to separate code execution by a passed in string.

Okay. I decided to go with one layerManager because Bicycling Layer and and Transit Layer has the exact methods. There is nothing different apart from the class names. I thought it would be an overkill to have 3 services with the same methods and properties, but I will separate them since that's how google does it.

I agree to have one uniting manager. but I think there should be different methods in ApiWrapper and in google map types

SimpleChanges is part of angular component infrastructure, and should not be leaked to our Manager classes. I recommend going back to how it was originally.
Additionally, keeping in mind that there is only ONE parameter for both bicycle layer, and transitlayer, it doesn't make sense do the entire Object.keys, filter, etc.
You can just do
if (changes['visible'] != null) {
return this.layerManager.setVisible(this, changes['visible'].currentValue);
}Of course keep the above lines of code in the directive's ngOnChanges method, and not in manager.
