PeteHski We've been through this before. It isn't so much the rate at which the "gyroscope"s come up to speed (acceleration) as much as it is the response of the gyroscope to rider input that makes light bicycle wheels desirable.

The output of a gyroscope is perpendicular and at a right angle to the input. So, when in motion, a left/right turn of the handlebars results in a force at the top and bottom of the wheel whose effect is to lever the frame over about the wheels axis of rotation.

Lighter gyroscopes require less steering input to change orientation at a given speed. This high rate of response to rider input tends to be considered a desirable quality. "Nimble" and "lively" are appropriate terms.

Conversely heavy gyroscopes require "gobs" of effort to change the gyroscopes orientation. The higher rider steering effort required to cause the lever effect that moves the frame about the axle into the desired lean angles necessary for travel upon a bicycle leads to what many consider a "sluggish" feel. This slow rate of response is often (but not always) considered a less than desirable quality.

The compromise of light responsive steering input and steering stability will continue to be the subject of armchair quarterbacks for many years to come.

I have a 950 gram wheel set. I actually think they are too light. If ever such a thing were possible. Any bike they are installed on does exactly what you asked before you realize you asked it. They are anything but "relaxing" to ride.
