two more views of the seat arrangement using the mountain bike shock.
I will add a seat post an utilize a standard seat.

It will be interesting to hear how the suspended seat works out for you. It's a very unique and innovative idea. Have you given any thought to fabricating a custom seat pan with foam padding and upholstery? Something akin to a banana seat shape?
Keep us informed.

Im looking at it now and I see I need to redo the front pivot. I made it w a 1/4 pipe nipple and I think it might be prone to failure. Im afraid to hang my junk on it without some additional stuff. I have already brazed a stub of seatpost on the bar. I decided against a pan seat or banana cuz I just grabbed what I had on hand. Mebbe next build

One more pic still sorting out. I shall add a piece from the chainstays to the seat tube to strengthen up the rear end. Just took it for a pedal drive. Might work. The seat is comfy. Need to figger out what happens when shock bottoms out to make sure I have clearances and safety. Might keep the seat setup as is, need to burn grey matter and figger it out.

That is a long 'moment arm' to support. The stress is going to be on your brazed areas.
If you're confident about them you might consider some 'bridging' between the two trailing arms. That would stiffen them considerably but it won't take the stress off of the brazed joints. What material are the extensions made from?

The extenstions are gas pipes. Nice and thick. I sleeved the joints 3" inside the connections for strength using some all thread. I ground off the threads to fit inside the gas pipe and chamfered the mating surfaces of the 2 pipes, err tubes were joined. I'm sure I got a good join where the brazing worked into both tubes and the sleeve. Im planning on adding an arm from the chainstay arms to the seat post just behind the brazed joint. The shock's lower mount is connected to a U shaped piece that wraps from R side chainstay to Rside seatstay and "bridges" across to L side seatstay to Lside chainstay as it were.

Sounds like a plan to me. Keep us informed.
It's looking cool so far.
