I was thinking the same about Wahoo/Bryton/Garmin mounts for the Brompton so as not to block the fold (in the same way I have to rotate my metal Exposure mount upwards to stop it from hitting the forks when I fold) .
I’ve recently wondered whether the ‘out in front’ mount could be used the other way round, so that it mounts the unit behind the bars rather than in front. Also, whether the lip on the front of these mounts might be require a little ‘shave’ of the plastic, AIUI the actual mount interface works forward or backwards, but the mounts are styled aerodynamic to obviously favour mounting forward.
