Grafton or other Edwardian?
By: Paul-n Date: September 9, 2025, 4:00 pm
---------------------------------------------------------
Hi all
I have used the contact form on the
HTML https://www.cyclekartsgb.com/contact
web site maybe 2 weeks ago
and have not had a reply yet ?
Is this the correct way to contact the committee ?
I have some questions about a possible build where I want to see
if going Edwardian I can build the vehicle I want AND still be
considered a CycleKart and attend your events.
All the best Paul

Paul-n, I applaud your efforts in thinking Edwardian. As I
complete projects for other organisations my Napier is very
close. Would have been at Wilton Mill if I hadn't missed the cut
off. My Napier build is on the build pages.

Thanks for the input , your build is inspirational however I am
really approaching my subject from the opposite end of the
spectrum ?
I really want a Cycle Car similar to this :-

/>
Based on the book How to build a Cycle car :-

Now the driver looks sort of like this in the car :-

However an Australian is making a great job of building an aged
CycleKart replica however following the Stevenson formula it
does look wrong ?

I think the answer is to build it as near to 100% scale as
possible and do a body more like this :-

Where the engine is hidden this allows me to get the driver as
far forward as the real thing and then build a tail similar to
some of you folks where the engine is hidden in a boat tail/fuel
tank.
Oh and of course the dream of many CycleKart builders to get it
road legal !
Sorry for the ramble , thinking out loud [ always dangerous ]
all the best Paul

The Stevenson approach, by which I assume you mean a structural
plywood box with chassis rails, is a great way to start and
makes for a light cyclekart. This approach is well trodden and
is recommended for first builds so more people are successful.
It’s far from mandatory, and being a
creative/independent/?stubborn crowd, cyclekarters often use
different techniques. The important reference point is the
handbook which sets out the parameters.
Looking forward to getting your outline plans.

Tim Gunn's Grafton build is exceptionally cool. In the loft of
my garage is another chassis he made (and several other bits)
for an even smaller Grafton. In case you didn't know, Grafton
name came from "find bits and Graft other bits on".
I like /love your thoughts.

By Formula I meant basic dimensions , which I believe this club
has adopted in the handbook.

Which led me to contacting the committee as my plans would take
me considerable ' Off Piste ' ;D

Tricky as I have to amalgamate the Grafton from the book with
the Stevenson side view , superimpose the Grafton driver where I
think he should be. Then scan in 2 halves and join to make a
single image for both 100% , 90% and a 80% Grafton.
Every thing is 1/6th scale as that is the size of a wooden
artist manikin , which is then used to build a mixed media 1/6th
scale model to
see where the bits might go .....

Intriguing I think he also built the second one pictured as
there are lots of bicycle parts used [ one of his trade marks ]
and it has his logo
in a plaque on the dashboard. However whilst it has some name on
the dashboard it is obscured by the steering wheel and so it is
difficult to search for more pictures of it ?
[quote]In case you didn't know, Grafton name came from "find

yep read that somewhere , or maybe on one of his videos ?
[quote]I like /love your thoughts.[/quote]
Initially I wanted to rotate the engine vertically and set the
CVT vertically then drive a chain to a lay-shaft just in front
of the seat.
This would better mimic the old single cylinder engines used in
the day , and the Honda fuel tank could be partially masked by
the
actual fuel tank of the prototype.
However the Australia guy said the engine may not be happy
vertical and it could cause difficulties with the fuel filler.
I don't think anyone has tried that.
Obviously engine in the back is much easier [ but still
challenging ] .

Hi all
So first drawing :-
[img width=1024
height=458]
HTML https://i.postimg.cc/HkgLtkBg/100-per-merged.jpg[/img]
Background drawing comes from ' How to build .... ' @ 100%
actual size then reduced to 1/6th scale
In blue I have drawn the driver profile from the Stevenson side
view.
In red is the outline of the Stevenson CycleKart also in 1/6th
scale
So this is how they would look should they meet in the flesh.
Their respective wheelbases are in Black and red above the
bodies.
Now I can see how allowing the Edwardian cars to be bigger IF
the prototype was a big car , that
Napier being built or one of the other Aero engined monsters of
the day would make sense and look good.
However does this really work for the Grafton style Cycle Car
built as a CycleKart.
If the answer is no.
I can either try and shorten the above body to reduce the
wheelbase I think 2000mm is possible
or
I will do the same drawing with a 90% Grafton and if necessary a
80% Grafton for your consideration.
My dilemma is simple :-
If the car I am thinking of building is not acceptable as a
CycleKart then I have no one to play with.
My only other choice then would be attempt a 100% version and go
for the MSVA so it is road legal.
Around where I live [ fairly rural ] I have 2 car shows and the
Newark Auto Jumble all within 20 miles of where I live and
almost no dual carriageways
to reach them so I could use a road legal Cycle Car on weekends
in daylight fairly safely I believe.
all for now Paul
