Balancing would be tricky though, unless you have a third wheel contacting the rails and then you are actually spending a lot more energy.

I know this isn’t where you’re going, but it would be awesome to have a system of bikes on rails with steel wheels.
About a quarter of the rolling resistance, but it is only ~11% of all resistance.
Braking and accelerating would become really fun, but wheels would last forever.
