Used some old handlebars from a dirt bike and got the twist throttle and front brake working.
Have my wheel mounted facing the ground and upside down.
It's not pretty but I feel like it bring the enjoyment up some.
Just throttle and brake cables from the dirt bike also.
Drilled holes in the bottom of the pedals and then through the pedals.
Video explains and shows my not so good driving :D

I love it!
Not sure how much you can adjust the wheel, but I found the less movement you have the less unnatural the inverted steering felt.
Also, maybe you could try putting your bars a little bit in front of the center of rotation of the wheel instead of behind like you have now.
Keep going man!
I used a steering wheel to start development and found 40% the max for turning the best.
Keep the bars behind the center of pivot or it will get even move unnatural in feeling
Best of luck for the future of building

That depends on how you use it. With force feedback the swivel motion makes no sense at all. I think your system is pretty spot on for non-directsteer, that really doesn't require a force feedback wheel.
There is no universal truth in this, so keep testing. Looking forward to seeing what you come up with @
Chad!
Currently I have 40 degree of rotation. I may be pushing a little past the limits with all the leverage I have though.
I will be experimenting with the location of the bars on the wheel.
It's quite a fun project and is not quite as easy as I thought.
The overpowering is what makes directsteer so hard, you don't get a feel for what you're actually doing.
Are you playing through steam or standalone? If stand-alone I'd suggest you to try version 19 (not b). It had much stronger force feedback code and made directsteer less impossible (though more erratic).
If running directsteer I'd deffo move the handlebar to on top of the rotation point or in front of it. That would give you two attachment point too = more solid feel.
I have noticed that not having much feel of resistance in the wheel has caused problems with being smooth with my steering inputs through the corner.
On a real bike when countersteering there is a nice force pushing against you at the handlebar grip. To try to recreate that, I have turned spring centering up, moved the handlebars to the top of the wheel with a pivot point directly in the middle, and now have added springs from each side of the handlebars to the steering wheel.
It's not perfect but getting better.
I currently have the standalone demo, I will have to check which version. I will be buy the full games soon though.
I feel like I need ffb dampening on which goes against everything sim racing. But when I try to turn it on in my steering wheel settings it does nothing in the game. Not sure if there is an override or something.

Try running this version instead, it has more powerful force feedback. Makes it much easier to control.
I'd move the handlebars even closer to the center of the wheel.
Also when calibrating in gpbikes, try not using the full rotation. This could give you shorter throw and more feedback earlier. Could make it a mess to though. :)
The steam version is a bit cheaper, but doesn't give you the option to run older versions so not ideal at the moment perhaps..
I found it way easier to ride in Direct steer mode with the late beta's if you reset the virtual rider default front/back lean more in the back (i'm using Vr i don't know if it work on standard scree). You can lean more easily when the neutral standing of the virtual rider is more backward !
Demonstration of version 2 and a lap in a much slower bike!
That's an interesting approach. I like the low speed detail! The high speed approach I'd have to try, sometimes what looks a little awkward works real good. Nice progress man!
Doesn't autoclutch work well? Maybe it doesn't slip enough..
Looks interesting. Like a mix between DD's swivel design and regular steering column.
The auto clutch works, it must be because of the lower powered bike or something. If I press C and get the revs up it will take off just fine.
It's definitely not perfect, but I can at least make a full lap now, so I'm pretty happy.
Next step is to start working on peripherals!
Cool!
What peripherals are you going for?
I would like to build a shifter and a clutch but that will require ordering some potentiometers and other things.
Still learning these things as I go so will probably be a while before I get to a motion sim though.
I made a quite simple clutch from a bicycle brake handle, a small spring, a hall sensor and a magnet. Works really well.
Unless you have a 3d printer, I can send you stl's for a hall sensor clutch.

Sounds interesting as still using a potentiometer. Please PM me Chris....thanks

No 3D printer but I have been reading your m300 thread and there's a lot of good information in there. I'll have to look more closely at it to get an idea for the clutch and foot pedals I think.
This is the bicycle clutch. Could have been a more powerful spring, but it did the job and I liked it. You cannot see attachments on this board.
The sensor just plugs into an arduino, bodnar or whatever you have.
That's a nice design. So I'm guessing the magnet getting closer or further from the sensor is what allows slipping of the clutch?
Yeah, you feed the hall sensor 5v and get back a voltage that goes from 2,5-5V or 2,5-0V depending on which pole you have facing it.
It's a simple design compared to using a pot, which usually gets quite mechanically complex. Before I had the hall sensor I used the bike brake wire and hooked the end up to a sliding potentiometer. That worked good too, but it was nice to lose all the extra stuff.
I'll have to look into something like that. Just ordered a bunch of arduino components and potentiometers and small motors to mess with a motion platform!
But here is my last creation, not my most prized masterpiece but it gets the job done for now. Haha(https://i.ibb.co/Pwk8WJt/10-B38052-181-F-4-DC4-8259-0-C9080781-E4-D.jpg)

Exciting times! What motors did you get?
Hey, if it shifts the bike! Looks can come later.
Well, I should clarify they are only miniature motors, nothing full scale yet.
I would like to build a motorcycle cockpit first I think.
You learn a lot from building a scale prototype.
Yeah, no point in a moving platform without a cockpit;)
How's it going Chad?
Things are going. I've been working on a load cell front brake. I'm thinking my next purchase is a 3d printer( and then learning how to use it) because I feel like I need custom things to make my designs work.
I just picked up an Rift S but now need a better computer. Lol Making progress but slowly.
So I've been taking this time to actually race and get better at GPB.
How is the motion coming along?
Nice! Let me know if you want to bounce loadcell ideas.
The printing really opens up possibilities otherwise only possible with quite advanced fabrication methods. Do it!
I had the same progress when I borrowed a Vive and later got a Quest2. Now my computer is still old but upgraded to the point of melting, would probably have been cheaper just to get a new one 😆.
I have never really gotten any good at driving. I'm hoping to make the controller close enough to reality that I can use my irl riding experience instead. 😄
The project has started, with all the theoretical stuff a bachelors thesis is based on. If our time plan holds (not sure why it would) we start building in a month or so.
I'll bounce some ideas off you when I get to that point. I feel like I have a pretty solid design, but it will show it's weakness when made into reality I'm sure.
I'm just on a laptop with no DisplayPort or anything. So I think it is definitely time to upgrade to a gaming computer. I haven't played sim racing games in years so I'm really lacking haha.
Here's a little video of the most recent changes to my handlebars and then some laps. I'm thinking I need a lean axis next for the handlebars and whee to pivot in a half circle. I think that would help with lean but I think it would be more beneficial to be used with VR.
I'm really excited to see how VR feels, I'm expecting to want to have an actual motorcycle rig as the next step to gain more immersion.
Did you use that in the race yesterday Chad? If so, it works very well!
Oh hey, nouvaic! Yes I did use it in the race. I'm still getting used to the controls but it has seemed to be working pretty well!
Nice one Chad, that looks like it works really well :) I held on to my sofa at turn 1 (3:30), lol

VR is something else man, you gotta do it. It feels like you could get abit of Scott Readings 'helmet down' action going on, lol.
https://www.youtube.com/watch?v=FsQWMovTPfc.
Totally agree, in VR this sim is next level greatness. I'm following these discussions closely as the plan is to build a dedicated riding rig for it.
I'm glad to hear VR is good in the sim.
I've never tried VR before, and having some real world track riding in curious how it will compare.
Helmet dragging might make me a little disoriented :o
I'm still working on getting a new computer so that will be the next purchase to get the vr and motorcycle rig going.
I dont know what others think but i have a few mates that dont get on with VR too well. They suddenly feel abit queesy and thats just sat in my car race rig with no motion.
With that in mind, im building my rig so it isnt dependant on VR. Or i could just tell my mates to spectate from the sofa while i have all the fun onboard ;D Personaly, i can stay in there 'till the battery goes flat on my Quest 2 but its probably worth keeping in mind.
Go for it Chad, if you dont throw up, you wont be disapointed, lol.
I haven't used VR with motion, but for me I get more affected playing games where there should be motion, like rally jumps, and there is no motion.
In gp-bikes I have no issues at all, it kind of makes sense motion-wise just sitting on a chair. Mx-bikes is a bit tough though.
Motion sickness sould be less with motion rig, cause the difference of what your eye see in VR and what your brain / internal ear / body feels is the main reason why you fell sick with VR ! so this difference sould decrease with motion rig, even it will never be like IRL (lack of G force etc .... )
