No-Fork project, bicycle geometry hacked

Too many words, and pretending to know stuff...

Here's the No-Fork fork. Show us how it is not simple...

Actually mdcc did stated that the fork have the advantage of being the simplest one to produce, but the overall cost of the component outweigh that small advantage.

The conventional fork with multiple separate parts welded together does seem to be complex to manufacture, but a cheap and nasty unicrown has only 3 parts* and two welds (fork ends are just the blade tube squashed flat), where the No-Fork has at least 2 parts and one weld (the leg and the tube at the base to take the axle), so in terms of simplifying manufacture, you have little if any advantage.

Shifting the cantilevering required for a single-sided design from frame and axle to wheel and axle might be slightly more structurally efficient? (Though there can't be much in it either way.)

Good point! maybe a bit more structurally efficient in one design, a bit less in the another...

I dont claim (contrary to what Tester wants you to believe) enormous advantages over traditional bike design. Just that Ive created more design space.

Not entirely, he's saying:

Deliberately avoiding the point made.

and heres me thinking people only cared about what colour a bike is

As long as its baby blue you will be fine on the colour.

^hahahaahahahaha

Love that color, think its at least 10% faster :-)

These just came in. A manufacturer sent them to me to experiment with off center spokes for less dish wheels... Thanks!

have you tried crash testing this yet? If you need volunteers I'm in Rotterdam and fairly thick skulled. You need to provide helmet and whiskey though.

I'm sure you want to know what a hard impact would do to that fork in comparison to two nice solid teardrop profiled fork arms and also how the headtube/downtube/hub assembly will react. Will make a good youtube vid anyway...

and btw your giraffe looks shit and has no way of balancing itself unless you intend it to be ridden by someone who can compensate, but I'm not crazy enough to volunteer for that .

What about the bottom half?

Entire No-Fork

Bottom end

Any capable singlesideleggedbiped can handle this issue, clearly you have little experience in the zoo-o-drome.

Roger that. Crashtestdummy definitely required! Will have helmet and whiskey ready!

Will spend more money on silly project, but first have to decide about the material for a final build. 953 or ti.

Presumably once the discs are connected you won't still be using radial spokes...? Or you definitely will need that helmet. And the whiskey.

Next weekend will be cnc weekend fer new hubs. with these off center rims, following sapim advised spoke pattern....

but will have the whiskey anyway :-)

I've been wondering, is the raised horizontal chain-stay an aesthetic, structural, or fabrication driven decision?

Purely aesthetic! The usual rear triangle didnt work out somehow. The first deviation was the bottom bend in the seat-stay. In the process of building I tend to hold tubes in place an view from a distance and when I put a tube horizontal just above the chain it looked kind of clean. With the chain on the outside of the frame you dont have to split the chain to take it off. I know there are frames with a rised chainstay that also overcome this problem, so i felt that the stay as it is does undermine it a bit. But I still thought it was OK.

Think it looks cool when riding too:

needz a belt drive

seems like the bike is difficult to steer
it's zig zagging across the road something chronic ?

whose legs are those ^^

Can they not ride that bike straight it looks like a pissed person weaving all over the place

with nice legs

The bike was a size to big for her, and first time fg so she didnt feel comfortable I guess. And 10 deg. below zero that day.
The weaving is on my instruction to show left hand side/right hand side of assymetrical bike.

The tester leggs are the missesez:

GET OFF THE MOTORWAY FOR CHRIST SAKE THERE ARE CARS THERE!!!!!!

Looks like the wheels are trying to right themselves and thinking about it, they would, wouldn't they?

No-fork, you seem to be going on the assumption that because a wheel can run horizontally on an angled surface (cambered road) then an angled wheel can run on a flat surface?? Surely that is not so because the centrisomething force will try and make the wheel horizontal and the rider will have to fight against this?

Sorry if this has already been covered.

it haz.

not sure i'd read it for anything other than my brilliant animal design hacking though. much more original and useful than any of this bicycle orientated charlatanism that's been going on.

I thought the same..but there's a video of him riding with no hands. Seems to run quite straight.

As OP said, the technology may be put to good use somewhere else besides just a standard fixed gear bike.

I would have thought centrifugal/centripetal/gyroscopic forces would simply try to keep the rotating wheel at what ever angle it is at, not try to force the wheel horizontal (or vertical). Such forces are always being fought against by a rider on any bike when trying to do anything from steering, leaning, changing direction, whatever, so I doubt it would make any difference.
