For space efficiency, yes. Bikes are actually better than walking for CO2 output. Your food has a CO2 cost, and bikes are really damn efficient at turning your food calories into forward momentum. Ebikes are even better on a per mile basis, but their higher manufacturing cost mean they never catch up to lifetime CO2 output of a regular bike. Still, whatever gets more people on bikes is a win in my book, ebike or otherwise.
The inner diameter is less than the outer diameter which makes for a small overdrive gearing ratio, translating to fewer steps even under normal operation.
So uh, walking, buses, and bikes for the win?

The hampster balls also win for style points but that’s arguably walking with extra steps.
Fewer steps if you get going fast enough and just ride tumbling ass over tea kettle.

That sounds way less fun. You go ahead and calculate how many fewer steps like a nerd and I’ll tumble around in one like a cool person.
Unironically yes
Scientifically speaking yes. Also trains
Train using road space for comparison:
