## Description

THALOUS Bike Seat with Backrest Oversized Comfort Bicycle Saddle Replacement Soft Memory Foam Padded PU Cushion Universal for Tricycle Mountain Bike Commuter Bike Electric Bike

Review: Perfect for the 3 wheel mini foldable trike - Perfect proportions for models like the Topmate ES33 and 31 and 35 ! The seat is 9 and a half inches just right . The other I tried was11 inches too much seat for such a small trike . I weigh 150lbs and am 5ft 10 . Mini trikes have a smallish frame I use a Topmate ES33 and I also have a Topmate ES35 dont use it much tho . But this seat it is perfect for this trike . Comfortable ,not overly comfortable but enough to get from point A to B discomfort sets in at point C for me . Respect that , the price isn’t that high so that’s enough for the price to justify itself . It doesn’t take up to much front space and 9and a half inches seats are the only solution and this one I am glad I purchased and would do it again
Review: Comfy bike seat - Very comfortable for my E bike. Good quality
