EBay search name rearwheel 3 holes 3.00-8

[wheelchairer]

Can anybody tell me what I need to search For on eBay to find some appropriate rear wheels that take a 3.00-8 tyre and will mount on this flange with 3 fixing bolt holes, please?

[Burgerman]

Its either a wheel from a sunrise Qxxx chair or from a Sunrise Jive, both have a different PCD, MY GUESS IS JIVE...
And I think the salsa 4 bolt hub fits too... And the 3 bolt ones are interchangable.

Jive bigger PCD

Qchairs various Q300, Q500, Q700 ETC. and smaller PCD

What is the chair?
Hopefully that motor isnt held on by the 3 6mm bolts I see

[wheelchairer]

https://www.ebay.co.uk/itm/167005193795

There are 5 new bolts in the picture. Had to modify the motors to fit to the mounting points.

[Burgerman]

What chair?

You want jive rims.

Important. Programming set 45mOhm compensation as they are 6mph ones. And equally importaant be sure to set correct brake voltage! Or big £££ issues ahead!

Thank you, I will get back to you on that please.

[wheelchairer]

they do say dynamic system only, will I be able to modify the cable for r-net, And use them?

[Burgerman]

Well if wrong, you can make an adapter or swap the cable ends.

thanks for the heads up.

[wheelchairer]

So I bought these
https://www.ebay.co.uk/itm/167005193795

These won't fit
https://www.ebay.co.uk/itm/286178080407

And these won't fit
https://www.ebay.co.uk/itm/166534712672

Any ideas

[Burgerman]

If the motors ARE actually Jive and the rims are actually jive then they do fit.

The Q chairs. have a smaller bolt circle so the bolts are closer together.

So is it the jive rims that were listed incorrectly or the motors? I suspect the 3 spoke wheels you have are really from a q700. Not Jive. And the guy selling is an idiot. They LOOK similar, they are not.

I would not expect the rims in the 3rd link to fit, smaller bolt circle.


The jive wheels in the photograph ARE jive wheels. The removable section is at the back. On a Q chair wheel its on the front. So what did they actually send?

[wheelchairer]

It takes me a while because I have to wait to about For the man at the garage who has my wheelchair and the moment.

The garage mechanic said that the ones in the 3rd link were smaller again than the ones in the 2nd link, but still not small Enough. The diameter of the circle that Links to 3 bolts is 84 mm diameter. So I'm even more mystified As to what to look for.

[wheelchairer]

Just spotted these from the mechanic.

What do I need to do now to address the above.

the seller says, dynamic system only, but they have plugged straight into the r-net power module. is it possible that connection will work okay, or do I still need to make some adapters?

[Burgerman]

The seller is probably an idiot. Never personally saw a dynamic system used on one of these. But they WERE available. As a special built4me option. Jive 6mph I think?

Read brake voltage off motor label. 12 or 24. If they came from a sunrise chair they will almost definitely (probably!) be 12V brake.
Set that in programming. Be sure that it fully releases. Loud click, motor can freely turn.

Set 12V

Set 45mOhm in motor load compensation. Save to chair.
Set yellow fields as below:

[wheelchairer]

Yes you are right, they are 12 V.

I've attached my r-.net system file, because as you can see from my picture it doesn't have the same options as you. Is there anything I can do?

This is the sunrise dealer software

[wheelchairer]

the system file

They stopped producing this Lifestand 10 years ago, so cannot any longer get parts for it. Love the chair, just wanted to boost the speed up to 6 mph.

[Burgerman]

Because you are using a dealer version which really means "very limited version" with all the important tech stuff removed (to save you from yourself)...


PM me, the things you need to change are visible to me...

Your power module is the 90Ah (80A really with a couple of secs boost to 90) rather than the 120A version. Should still work OK.
Your MOTOR load compensation is set to a too high 60mOhm so the chair will be very "snatchy" and unpleasant...
You voltage is set to 24V and so wll soon burn the brake coil and $£££$$ , set this to 12V brake.

I changed the things on YOUR file that you need to change as shown below in yellow!

[Burgerman]

Here is the changed safe file for you new motors.
It is possible it may turn the wrong way or forwards and back be reversed etc but thats easy to change. Theres no convention for motor wire polarity.

Seriously I am surprised you can hit a doorway with those turn settings.

But I left them alone.

If you don't mind I'd really appreciate it if you could Change the settings to what you recommend and I will try that

[Burgerman]

Well I cant really do that as every chair is different.
But I will add a 3rd profile later and upload it. It will probably need some fine tuning.

This will be a new profile, and will be for indoor and outdoor. You should only ever need this single profile. Called All Speeds.
You can just change speed from 1 or 2 indoors to 5 outdoors. Start with 1...

When I turn the wheelchair on I can stand it up move the back rest et cetera in mode, but when I pressed the Mode button and to go into the profile settings nothing happens, It just stays in the mode. Will it be because my carer has tried to drive it before I have put these new settings in? If so what are the likely consequences, new Power module?

[Burgerman]

You cant damage the power module that way.

Do you mean the mode button doesent work? No idea why.

I didnt change anything at all other that as shown. So nothing is any different other than motor settings, brake voltage.

So not really sure what you are describing. In any case, you can always put the old profile back on and test. (But dont try driving it with that old one!)

[Burgerman]

I added a profile that allows the thing to steer properly at every speed. TEST it dont change anything!

I also changed the following items in yellow, below. And added a 10% compensation increase and a 10% torqe reduction to the new 3rd profile only.

okay can you just what the big issues are, under what circumstances, What would you actually have to do to cause damage?

The motors were in drive.The wheelchair is in profile 1. You try to move the wheelchair but nothing happens. You switch it off.

Would that cause damage?

[Burgerman]

No.

Unless you tried that with the OLD settings with brake set to24V. Then it might damage the motor brake but not instantly may take hours or days.

Load the new profile I just posted and then tell me EXACTLY what happens.

[wheelchairer]

Okay I have no carers now. So I will come back to this

[wheelchairer]

Swapped the pods From another wheelchair over this morning and it worked. Neither the profile or the mode button Is working On the broken pod, So I'm going to have to buy a new one before I can try your profile. Thanks very much for your help mate

[Burgerman]

If in no hurry and you FISH with care you can get UNUSED / BRAND NEW joysticks for:

LED £30, to 40.
Colour CJSM1 for £80,
CJSM2 ones for £125 to £150.

I have 2 LED ones, 1 CJSM1 plastic one, 3 CJSM2 metal large screen ones. All sat as spares.

Theres non at the right price just now. Patience pays off. They appear occasionally, for a few mins only because if cheap then somone like me grabs them.

[wheelchairer]

Yes I did have to reverse the joystick to, like with the directions of the motors. And I still need to change the direction of the seating and standing control in mode. But the main problem is it's only doing 3 mph on profile two,1.5 on profile 1, and something similar on profile 3. I only use 2 profiles when I set it up myself, indoor and outdoor.

So will you have a look on the settings you sent to me, and see if you can help with this speed issue Please John.

Steaing wise yes it feels very good. It's a bit hard to judge because I can feel there is more weight on the front casters(Making them fit has took the rare of the frame a tiny bit higher), so I've had to pump them up to the maximum 35 LBs.

[Burgerman]

WHAT EXACTLY did you do? Theres several things and ways to do that incorrectly!
You must not reverse joystick. Only MOTORS.

And I still need to change the direction of the seating and standing control in mode.

Has it changed?

But the main problem is it's only doing 3 mph on profile two,1.5 on profile 1, and something similar on profile 3. I only use 2 profiles when I set it up myself, indoor and outdoor.

Now I am confused.
Is this one that you have "reversed" the joystick and not reversed the motors? If so then it will go very slow!
If not then I dont know what you are doing...
You only need ONE profile. With 5 speeds. And everything set correctly for the slowest speed, and the highest speed.

Steaing wise yes it feels very good. It's a bit hard to judge because I can feel there is more weight on the front casters(Making them fit has took the rare of the frame a tiny bit higher), so I've had to pump them up to the maximum 35 LBs.

If theres more than 1/4 to 1/3rd the chairs weight on the casters it will never work propely.

Right REINSTALL this. Change NOTHING at all.
Try moving forwards, TELL ME EXACTLY what it does.
Then try a TURN IN PLACE move joystick right. Tell me EXACTLY what it does.

Dont fix it. I will fix it PROPERLY and repost it here.
