In one of the Youtube videos I recently watch a guy rode a bike with a dropper seat post. The really cool thing about this dropper was it was wireless. The battery pack was underneath the saddle and the remote dropper lease button was on the handlebar.
If I didn't have an expensive seat post rack on my e-gravel bike I'd look into buying one of these. It would be great to be able to come to a stop, drop the seat down, so I could stand, flat footed, while still sitting in the saddle, then ride off, lift my bum off the saddle and have it rise up to its set position.
Here's a link.......VERY expensive:
