Newbie wheels
« on: 01 Jun 21, 01:36 pm »
Hi,
No doubt the first of many stupid questions, although I have read the whole forum and thanks to that, got many of them answered already.

One of the first things I want to source are wheels, as they affect a lot of decisions such as axles, suspension and steering set ups.

Is there any reason I shouldn't be pushing the button on these instead of pit bike wheels?

https://www.ebay.co.uk/itm/Rear-Wheel-C90-Cub-93-03-using-210304-Shoes-Rim-1-40-x-17-/114506279622?_trksid=p2349624.m46890.l49286

And these for the fronts

https://www.ebay.co.uk/itm/Front-Wheel-C90-Cub-93-03-using-210304-Shoes-Rim-1-20-x-17-/114816258641?_trksid=p2349624.m46890.l49286

No point in getting something rubbish, but to the untrained eye they seem more cost effective than buying pit bike wheels (which for some inexplicable reason I'm not too keen on), or second-hand Honda wheels and getting new spokes and rims, because they are usually in poor condition. - But you may know different.............

Thanks in anticipation.
Peter

PeterL,

Being a, “Newbie” myself I also deliberated which rims to go with and eventually settled on the rims you have provided the links to.

Others within the group kept me right on rims, especially on the front, which are those that have, or take, 6003 bearings (35 mm O/D), as they fit the 17 mm axles. In saying all this I did have problems getting tyres to fit the 1.2 X 17” rims.

I know this posting sounds a bit negative but the main point behind it all is to remember “rims that look a great deal may not be the case if you can’t get the tyres to fit”.

As for the 1.4 X 17” rims (rear seat) I had hubs made to fit and I am extremely satisfied with the results as the rims came with pre-drilled holes which were used to accept and locate the new hubs.

One last point, an idea was floated by Chris that a supplier list should/might be created which would help all members to locate parts and services at the best prices plus avoid those which may not come up to acceptable levels of service.

Just a thought 🤔🤔🤔

Regards

Scotty

You might consider the Honda ANF125 front wheels which are similar to the Cub, but are1 1.4 rims, and have bolt holes for a disc: https://www.ebay.co.uk/itm/114816258818.  The 32mm bearings are available in 17mm bore, see tabulation.

Thanks Chris and Scotty, 1.4 inch it is then! I was just worried that there might have been a fundamental flaw in my logic as the wheels seem relatively cheap  but there wasn't much Honda alternative.

I hadn't thought about availability of tyres, though it makes sense to keep them all the same size, only need to hold one spare.

The costs of wheels and availability varies enormously.   When I was looking I couldn’t find Honda wheels but did find a supplier who had a surplus of pitbike wheels so got those cheaply.   Can’t get them for the same price now, so would probably look at some wheels like the ones you’ve found.

Scotty, the “Where to get stuff” area of the forum is the place to find suppliers.  There is no definitive list of suppliers because the variety in what people are looking for is so wide and things change over time.  If there isn’t already a post on there for the component you’re looking for, then start a new thread and ask.

In terms of tyres, I was surprised to hear you’ve struggled to find tyres to fit.   Are you trying to find 1.4” tyres?  Most people run tyres in the range 2.1” to 3”.  Demon Tweaks has some great deals and I’ve also bought sets on eBay.   Andy Boulton had a pile of 2.5” tyres for sale.

Are people putting a spacer between the inner races of the front wheel bearings?
If you can drive round corners, you're not going fast enough.

Yes.   Had to make a larger diameter one than the one that came with the wheels (pitbike)

Hi Chris,
Grateful if you would confirm these are good for the front and back of the cyclekart, with 17mm ID bearings added for the Gemini front stub axles and 25mm ID bearings added for the back axle.

Sorry about the delay Steve, any of the 32mm o/d bearings will fit both sides of the ANF125 front wheels. It was pointed to me that if you're running one wheel drive ball bearings are too free running for the non driven wheel.

Can you have "too free" running , on the non driven wheel ?  Chris

Rhys commented that ball bearings in the free running wheel wouldn't be a good idea, perhaps he could explain.

If you have bearings in the non driven wheel you exacerbate the directional change with braking pulling towards the driven, and the other way when you accelerate. If, for example you have the right hand wheel driven when you accelerate you will be applying  right hand steering input to stay straight. Under braking you have to apply left hand lock to stay straight. Using bushes with just a touch of lubricant to minimise wear alleviates this to a large extent.
The wheel with bearings just obeys  what Isaac Newton discovered :)
Personally, it's fixed axle for me. I accept each have their own view.
Those who drove Graham Hill's MG at the first builder's meet will know exactly what I'm saying above.

We must avoid torturing our brains with false problems, it occupies but it can annoy. In jest!

If you use bushes of any material make sure you put a small radius on the corner of the key way channel or it will act like a reamer and soon wear out the bush if your going round corners. If you use ball bearings you don't have this problem. I can't even imagine the engine has enough power to give you a problem with it pulling to one side when accelerating. It might just about pull the skin off a rice pudding though.
