I have over 300 KM on Artifice Gordon and I wanted to make an adjustment to the seat. Short rides are one thing, but when you’re sitting on the seat for a few hours and riding 30KM or more, the comfort of the seat is of paramount importance. In fact, seat discomfort is one reason why I own a trike and I don’t ride an upright bicycle for long distances.
This is a photo of the left seat hinge, taken from the trike’s right side with the seat folded down (looking at the back of the seat frame, side-on). I unlaced the mesh seat cover and pulled it out of the way to expose the side tubes and hinges of the seat frame. On longer rides, this seat hinge (the black metal part) irriates my lower back. The angled bracket is toward the inside of the seat frame. BTW, I’ve discussed this issue with the designer and he is going to address it with a design change.
This is a photo of the right seat frame tube (taken from the right side of the trike with the seat folded down like the above photo). I’ve covered the tube and part of the hinge with foam and tyrapped it to the frame tube.
This is a shot of the back of the seat frame folded down, taken from the rear of the trike looking forward. I’ve covered both sides with foam and tyrapped the foam to the frame tubes.

This is the right side of the seat tube bottom and the hinge, wrapped and tied.
The idea was to cushion the feel of the side tubes but mainly those angled brackets at the bottom of the tube that form the hinges. This of course did work well. Wrapping tubes is an old triker’s trick to make the seat more comfortable.
As you may recall, Walter (the designer) did the same thing to the bottom of my seat during my recent visit to TW Bents:
This procedure improved the comfort of the seat bottom, so I was motivated to try it on the hinges. There was only one problem with my method:
This is a shot of the trike seat frame with the mesh cover removed, looking from the front of the trike. Notice the black and yellow sections of the hinges at the bottom of the frame tubes below the white foam. I can feel the black section of the hinge through the mesh seat cover when I ride. It only bothers me on longer distance rides, but I wanted to solve the problem anyway. I’m going to cover the black sections of the hinges only because they’re on the inside.
Closeup of the left side. This illustrates the problem. The bottom of the hinge on the inside is bare metal (well, painted bare metal).
Sitting on the seat confirms that neither the hinge top or bottom sections can be felt. I’m going to give the new configuration a couple of test rides before I report that it’s a 100% success. However I expect it to be based on previous experience with the foam.
