Question: adult trike seat western saddle Does anyone know if the seat can be put on a regular bicycle?
Document: I went online and bought an adult tricycle, and at the same time purchased the trike seat. I took both to a bicycle dealer for assembly. I didn't even have him attach the seat that came with the bike. I'm in my early "golden years" and wanted the most comfortable seat I could find. I love the saddle seat. I can ride my bike in complete comfort.
Have not put the seat on the bicycle because there are no instructions. There is no information about which company made the seat. It just says "made in taiwan" For all I know this is a bicycle seat off of someone's old bicycle. Just a seat in a plastic bag. For this price?
We love this saddle. We put one on each of our bikes and absolutely love them. This is a product you will be happy you purchased. We use them on three wheeler bikes. Not sure how it will work on a two wheeler.
This is just what I wanted. My husband put it on my adult tricycle. It is roomy and comfy. Just right for me.However, after some use, the seat tilted as it does not have the under seat support I have seen on other seats. Also, as the seat was wider, it was not as comfortable to peddle as the smaller seat. Hence, we put the smaller seat back on the bike.
I was very excited to find this seat after riding on a friend's trike with a large saddle-type seat. It arrived promptly, but box contained a U-shaped mounting bar and no instructions. After much fiddling, I decided the U-shaped tubing was not meant for my trike model, since there was nowhere to attach it. Judging by some scratches on the underside, I suspect this was a returned product. The saddle itself is of a lower quality than the seat that came with the trike.
I bought my wife a trike and she wanted a larger seat for it. I purchased this one because it specifically said "adult trike seat." I installed the seat and she likes the size of it, however, there were no instructions and the U bracket that came with it (no other hardware was enclosed) cannot be installed on the trike so there is no support for the back of the seat. Installation instructions would be nice to have.
I adapted it to fit my regular bike because the seat that was on the bike was very uncomfortable and caused a I won't mention problem, but I'm good now and comfortable.
Looking for a larger seat that was comfortable. This is it. Easy to install. My husband is very happy with the seat on his trike.
I ordered this seat for my Schwinn adult tricycle. It is perfect. My husband installed on the bike in about 5 minutes. It is very comfortable and I love to ride my bike now without a sore rear. I also like the fact that it has no horn on it to rub the inside of my thighs. Great seat!
The seat is large and comfortable,  The installation is quick and easy. My trike did not have a bracket for the additional support brace that comes with the seat. I read in the reviews that other people used the seat  without the additional bracing. I decided I wanted to use the brace. So I fabricated a bracket using two sheet metal strips and a 10&#34; piece of all thread,  I  installed this on the down struts of the trike and it works great,  The seat is very secure ,
