Karts are nowhere near centre point either. Better to have a decent camber and loose the centre point IMO.

An alternative is to cut the booms just next to the headtubes. That would maintain centre point.

I'm planning on leaving it as it is, and see how it handles. If the camber becomes a problem, then I will cut and re-weld the booms near the end to get it neutral.

It will have not a big influence, other than on the tyre wear that will be on the side and the cornering. You will roll faster.
But I don't think that you will have a problem with it.

So its basically working now - I had to replace the pulleys I was using, since they were only held in place with M6 screws, and the rear one bent. I replaced them with a fully 3D-printed pulley with an M8 stainless steel threaded rod shaft, and that seems to be better. Had to crank up the 3D printer so it was printing solid with no infill, but the new pulleys seem like they should work. If not, I will try printing them with a TPU (fairly hard rubber) insert where the chain goes, and possibly replace the ABS parts with carbon fiber infused ABS. We'll see how it goes.

In any case, here it is in the basement, ready to start its first winter as an exercise trike:



I'll be building a new seat for it this winter, and painting it in the spring when it is a little warmer out.

Right now the issue I have is the trike is a little too short for me. What I mean by that is with the seat-back modification I did, the more vertical position pushes my shoulders forwards a few inches, and my elbows have to go behind my back to get my hands on the handlebars. Its not terrible, but I built this trike in order to have a comfortable ride, so I want it to fit right. I can't move the handlebars forward because they are currently clearing the tire by about an inch when I turn. I currently don't have any padding on the backrest part either, and once I add that this geometry will be worse for me. Its not too bad when it is going straight, but when I turn I have to really haul back on my shoulder joint, which is rather uncomfortable.



My current thought is I will give this trike to my wife (I was originally going to build hers next), and build a new one that has a slightly longer wheelbase. She is ~8" shorter than me, so she should have no trouble with this one. I think I will design a new frame entirely in CAD first, and make sure it has the parameters I want before I start building.

I think that abs will work, but if not you can make a combo of abs and tpu. Abs on the inside and the outer part from tpu. Than you can put bearings in the abs and the tpu will make that it is less noisy.

As you move the handlebars a bit more up, than you can move the even a bit more forward.

I did both designs in cad. First one, I used a lot of the warrior design and changed it as surten points. The second one, I went from scratch and added things that I liked and improved on my experience from my first build.
Also I went out more from the cad files than I did with my first build. Now I design everything in cad first and fit it on my trike. First one, I only did that with the main frame.

So, it turns out I won't need a new frame. I sent a pic of my trike on the exercise roller to the store who sold it to me, and the woman who owns the store sent me an email back and asked if I wanted to buy a seat - she had a brand new, never used seat off a Terratrike Rover, and she gave it to me for a really good price.

I picked up the seat this morning (the store is an hour and a half drive away from here), and installed it this afternoon. It moves my butt back a few inches, and my arms are in a much better place now.



I'm pretty happy with how comfortable it is, although I'll need to try it some to make sure. The back is reclined more than my old seat, but it is still comfortable.

More reclined is what I personally like more. The 45 degree is a good angle for a trike.

The seat looks good on the trike.
I make my seat, do I can move it a bit forward as I recline it more and a bit back as I put it more upright. That helps with the steering position.

Here's what it looks like now, with the new seat:



As you can see if you compare it to the previous image with the old seat, my elbows are in a much more comfortable position now.

Did you also adjust the pedal position with the new seat?
As I see your trike, I can't wait till my second one is that far. Its strange, because I have one, but now I want to ride my new one also. Especially as I see your trike and tgst from others.

Yes, I had to move the pedal assembly back a few inches.
