I was looking to get a comfy extra padded seat for my upright city street riding. Rad City 5+. 27mm post right now with the Rad seat mount 50mm seat rails. 200lbs large butt 70+ years old. :-[
Thanks
My favorite large seat is the Sunlite Cloud-9 Cruiser seat 11X10X8 size, Amazon, $37. I use the Cloud-9 on my two 2016 Radrovers and two Radcity Step-Thru (2018 & 2023 models). Works equally well for me (6'3" 300lbs) and my wife (4'11" 130lbs).

Any problems mounting it up.
I removed the Rad seat and re-used the seatpost for the Cloud-9 at first. I later upgraded my seatpost to SunTour SR SP12 400mm suspension seatpost and later to the Kinekt XR 420mm Suspension seatpost. The only issue I had was with my wife being 4'11" and the SunTour SP12 350mm+Cloud-9 was too tall for her on her Radcity Step-thru. I upgraded her to the 350mm Kinekt Suspension seatpost with the thicker Cloud-9 seat because it had a shorter overall suspension seatpost mechanism. We are round 6-7 years with the Cloud-9+Kinekt seatpost for our Rad ebikes.
I got the cloud9 and found it a great improvement!

After trying 5 aftermarket seats on my 2021 MiniST2, including 2 Cloud9s, I settled on this one as the best fit for me as well. It may not fit everybody else as well, but it's very well made and worth trying out, like the other Cloud9 products.
At the end of 2020 I bought a Radrunner. I was 73 and weighed 255. The pavement around here is rough, and the seat was a piece of steel welded to the post with almost no padding. Right off the bat, I bought this for $30, along with a suspension post.

It was still terrible. I remembered what American GIs discovered in England in WWII. Compared to American bikes, English bikes looked like racers, with 60 PSI tires and little seats, but they were far more comfortable than American bikes. The secret was position. The English seats were much farther aft, which took weight off butts and put it on legs. Moving the seat back can also put weight on the hands, but raising the bars can fix that.
I removed the suspension post and bought a layback, which I heated with a torch and bent further, moving the seat back ten inches. I cut a triangle of plywood to support the seat, cantilevered so far back, against the rack.That made a huge difference in comfort, handling, and pedaling efficiency.
A year ago I bought a Radmission, whose OEM seat looks uncomfortably thin. I bought another layback post, heated and bent it, and sawed another plywood triangle to support it on the rear rack. I bought a seat that looks equally uncomfortable.

With most of my weight on my legs, it's plenty comfortable, even hitting speed bumps at 25 mph.
