shock absorbing seat posts

I do see some options for a 28.6mm but wonder if a 1/2mm or 1mm to 1.5mm difference is too much to properly fit the bike frame without a shim or sleeve of some sort?

Yeah, you need a shim.
It's worth the five bucks.

I just found this on AliExpress:
C$4.82 | MUQZI 100mm Long Seatpot Shim 22.2 25.4 27.2 31.8 33.9 to 28.6 30 30.4 30.9 31.6 31.8 33.9 34.9 36 Seat Post Tube Adapter


I got one so I could use my seat and NCX seatpost on my new ebike.

I recently replaced my 26" cruiser seat/saddle with something wider with a thicker cushion and recoil springs. I've seen some seat posts that are on some ebikes with some sort of recoil mechanism integrated into the post. Anyone using one of these seat post and do they actually work?

I've got a gell seat cushion on top of a Selle Royal Spring Seat, mounted on an NCX Suspension Seatpot, mounted on a full suspension ebike with downhill forks and 6 inches of travel.
I set my front and rear suspension to Extra smushy.

My ride is so comfy that I have to be careful not to nod off behind the wheel. 😁

Yup. I like the good old days of "mushy" rides. Like when everyone was using a 75 series car or truck tire, like a 205/75/14 or a 235-75-15, so when the roads decayed to "crappy" status you could hit those potholes and bumps and not dislocate a tie rod or ball joint or clamp your butt cheeks. My 1997 Buick has a 60 series which makes the ride worse than my 1991 C1500 with the 75 series tires. Now cars and trucks are using a 45 series tire, or worse, so it's like driving down railroad tracks on our crappy roads. I get used to riding on lower profile tires in the Philippines or terrible roads so when I come home and drive my old truck, I know what I am missing. Waaaaaaaaaaaa! Ha-Ha! I wonder if the fatter tires on bicycles give a nicer ride just like on a car or truck? I am using two ebikes with a 20 x 1.95 and 26 x 1.95 tires. Don't know if I can go much fatter with my wheels?
 
I am using an Upgraded Saffort Shock absorbing Seat post. So far I really like what it is doing for my ride
