Third this suggestion. Haven’t played much more than beatsaber, but its more of a workout than a bike ride for me. Of course its what you make of it. I personally like fast songs and I intentionally try to use my arms to swing at least partly. If you just use your wrists, you’ll probably get less of a workout. There’s also maps focused on fitness (lots of wall dodging and squats) if you want to do those (I typically find them less fun, so I don’t really play them).

OTOH, if you can make commuting by bike your normal means of commuting, that can be a way to be consistent in getting exercise. Even if using an ebike and only getting light exercise.
