Tech Forum / wheels and bearings
« on: 20 Sep 25, 12:28 am »
i've put in a preorder with redcircles for the cyclekart deal - thanks for the tip all.

so i understand that the bearings in these wheels need replacing and i've watched videos on how to knock them out.

My question is on what to replace them with. I'm seeing on gemini and cyclekart workshop:
rear hubs
mono hubs
adapter plates
then ebay has this bruses and bearings set https://www.ebay.co.uk/itm/286290846866
i also cant find any spaces to put between the bearings

as always advice very appreciated on the build

thanks again,
M

thanks for your patience jim. i've had a look - i may just go with marks page for the bearings as it's a little clearer.

i don't suppose you have the measurements for the axle bearings so i can check it'll fit my ladder chassis

Tech Forum / rear axle bearings gemini
« on: 19 Sep 25, 02:33 pm »
trying to figure out the best axle bearing for my 25mm 1020mm solid rear axle.

as far as i can see the option is flanged vs pillow block.

there are quite a few options for rear axle bearings however on gemini. any assistance or guidance of what to opt for would be appreciated.

axle bearing:
25mm or 30mm Axle Bearing & 3 hole plates.( 2 hole plate option )

A 25mm & 30mm Eccentric Cam bearing are available, the collar helps lock the bearing in place.

2 bolt hole Cast Flanged bearing with 98mm C to C holes

2 Bolt hole Pressed steel clamp bearing 85mm C to C holes.

pillow block:
25mm

thanks as always

Where to get stuff / Re: Torque Convertor
« on: 18 Sep 25, 08:46 am »
morning all,

just piggybacking off this thread. looking to get a torque converter for my cyclekart. The comet seems a bit pricey for the use I'm expecting to get from the kart.

I've had a look at the links and videos above. Unfortunately gemini appears to have been out of stock of their chosen clone torque converter for a while but on ebay you can get the vevor and this other clone. Any advice on what might be the better choice between the two?

thanks again

this is all great jim thanks.

interesting about the cheaper diff.

would the length of the used axle i've linked end up having too short a rear track width (it is 1" diameter and 36" length)?

hi all,
there is this rear axle that is 970mm in width with a peerless diff on looks like 100 series.

From what i've read on the forum this might be too short for the cyclekart build. But just wanted to soundboard whether it might work or if there's a way to extend or if the extensions just won't be strong.

Hi Nick,
Thanks for the reply. There's these two cycle karts I found on the forum that I'm basing around (attached). I couldn't pin down the exact types but the Ferrari 625/vanwall matched quite well.

Any thoughts on my questions?

hi all,
pleasure to be joining the cyclekart GB community.
i've had a few years building up my workshop armoury building various carpentry projects. I came across cyclekarts a few weeks ago and became enamoured with all the awesome different builds and creativity on display.
I was initially planning on building a wooden chassis as that's the tools I have and my competency. However, I came across a few builds that use a ladder as the chassis. And as I have two 3000mm x 340mm aluminium ladders I thought that would make a really good frame that avoids welding. I plan to bolt them together to make 3000mm x 680mm then trim down the length to around 2400mm.
One final crease to this is that I am planning on building a 2 seater cyclekart, because I think it could be amazing to drive my first cyclekart at my upcoming wedding.
I've had a read through the materials available (including Adrian's building guide), and watched plenty of videos but still will have many questions. I will be journaling the build here.


Main questions:
Whether to redesign the chassis to better accomodate two seats - or just place them side by side. I thought about making a wood batten triangle and slot inbetween the ladders to create a taper. I don't know whether that's overdoing it and potentially creating a big weakness area
steering kit design and purchase? how to have steering wheel on left side as two seater, but also adhering to ackermans steering rule is key to avoid slippage
The rear axle - i've had a look at a few online i understand i want 25mm - but i'm not sure how much clearance to have from the frame and the different types of rear axles (some have sprockets and other stuff attached, some are plain).
Do all 17inch rims fit 17x250 tyres?
Can someone explain the difference between all the 5 options for the front axle on geminikarts please
Any advice or previous builds on how to build a custom axle ideally without welding

Thanks for all help and advice
Excited about road ahead!
