Wouldn't it be possible to add a few radio variants as off-the-grid options? I mean tablets work off-the-grid and I'd expect a boom box (batteries?) or a grammophone to be functional off-the-grid. I know biking gives insane amounts of fun, but it would be nice to have other options of entertainment as well.
If you have ECO Lifestyle you can just add a solar panel or wind turbine to power a radio or TV.
I know you can and I have eco lifestyle. I still find it makes no sense that certain radios aren't available off-the-grid. It's like the basic principle of a boom box, that you can carry it around. If even tablets are for some weird reason off-the-grid it makes no sense, that a boom box isn't.
Yes it is a bit weird that no transistors was included. Maybe they will include one in a future patch.
