I had a local fabricator make two brackets. I mounted a nanobot scooter seat to the bracket and then mounted the bracket to the base plate of the e8. I've only done limited testing so far but I am pleased with the results. I did not sit on the seat but instead straddled it between my thighs. I was able to make very quick jerky movements with e8 and my body stayed with it. I had no sense of falling off. If anyone is interested in how I did this I can supply details.
