Wernmax, you did a great job with this trike. You are very creative and I also like what you did to to get independent suspension in the rear wheels. I have been working on an experimental etrike conversion as well because like you, I find the common rigid trike to be horribly dangerous from a tipping standpoint. Here is a photo of the experimental unit from a clean tech expo we exhibited at last November.

Since we will have plenty of on board power, I would like to install a gyroscope/accelerometer control to keep the rider stable at all times. It should be a fairly doable control since I know many have done it with Arduino circuitry.
I hope with can find a kind hearted individual or group that will take on this part of the experiment.
