Why isn't hydraulic taxi a thing? Hydraulic motors have

there isn't any range in power production is my guess

What does that mean?

Having to add a complex system powered by APU is just adding pointless maintenance unless the plane is spending a significant part of its operating hours in the taxi phase. Maybe for short-haul aircraft, but that market is extremely competitive and going against the grain is seen as too risky.

A set of wheel bearings are much more reliable and have fewer points of failure than an entire assembly that includes some sort of drive system. Also remember how fast those wheels must be able to spin up to in a very short period of time on landing, and how critical it is that the landing gear work flawlessly during landing, and how big of a disaster would be caused if any one of those wheels seized up during landing because some hydraulic drive system on it failed catastrophically. Also consider that for this to work at all you'd have to have an active steering mechanism on the nose wheel, which would be another point of failure.

Don't nose wheels already use active steering?
