@jon Those things are stupid, but they look useful in a press release and are cheap, so most bus agencies have something like that in the US (generally not that large).
While you can put a bike on them, I've been the passenger trying to get someplace when someone at an intermediate stop struggles to lift their bike on, and walk onto the bus - it was only 30 seconds, but that was 30 seconds stolen from my life and time with my kids.
Worse, they can only hold 2 bikes which means you will need to take steps to ensure they never become popular. Once they are full no more people can use them, so they need to be empty most of the time with only a few rare people using them.
They only hold 2 "normal sized" bikes: this means your family can't use them to go to a distant ride. This means you can't ride a tandem, tricycle, or cargo bike. Many recumbent won't fit either. You can't have a trailer (useful for both cargo and small kids).
Bikes on transit is a useful thing if you can pull it off. However it is very hard to do this usefully as bikes take up a lot of space. You have to put them inside transit - this means extra wide doors, and no/few seats in a large area. I don't think any bus is large enough for this, but some trains would be (you would want to discourage bikes during peak times, but off peak there should be plenty of room on a train) This is why serious transit agencies put bike lockers at the stations, and don't make provision for bikes on transit.
