here is my take on an ISM saddle mounted on a M4O Handle saddle medium.
First the parts list. Note the part at the top. That is the top from a regular bike seat post. I use it to hold on to the rails similar to how it’s used on a bike.
I used hockey tape to wrap the rear end to create a some friction where the rails touch the handle saddle.
Where my setup is slightly different is that i used the top of of a regular bike seat post at the front. It’s mounted with three cable ties.
And then four cable ties at the back just grabbing the rails.
The full handlebar setup. Still work in progress.
The part connecting the handle saddle at the front is from a Cinelli Spinaci.
