What does your grav bike look like?

Problem is, if it is one, is that local gravity fields vary.

And fractional gravities, whether on gravitational motors, lifters, or manoeuvre drive, need to be tuned to that field, usually in the Mars to Terra range.

though I've wondered if the generated grav field is always proportional to the local gravity. That is, the higher the local gravity is, the stronger the generated reaction force is. So that you will always get the same acceleration regardless of local gravity. Of course, this does have odd effects at extreme ranges: black holes, for instance But it was a thought so I did not have to worry about localized tuning of grav engines.
