I purchased
Sunlite Cloud-9 Bicycle Suspension Cruiser Saddle, Cruiser Gel, Tri-color Black to replace the original seat on my City Step Thru3.
It is slightly better but my Butt still hurts with this seat. I bought it after reading the reviews you folks have posted here. I don't know if I got a bad seat or got the wrong one but it surely is not a very comfotable seat. I need something better.
