I want a graphene bike. Sounds like painting it would double the weight...
Graphene is the strongest material ever tested,[137] with an intrinsic Tensile strength of 130 GPa and a Young's modulus (stiffness) of 1 TPa (150000000 psi).[138] The Nobel announcement illustrated this by saying that a 1 square meter graphene hammock would support a 4 kg cat but would weigh only as much as one of the cat's whiskers, at 0.77 mg (about 0.001% of the weight of 1 m2 of paper)

I'd like to see a frame material that is organic, living, able to regenerate itself and *heal* after having been damaged. Oh, and I'd like it to be both edible and tasty, as well as being a good source of quick energy and protein.

Boron is great... until you get a fiber in your skin. It is like a barb and can penetrate bone. Real nasty to remove.
I think the next material will be improvements in carbon called graphene. It can be much thinner for the same strength.
Here is the layout of the carbon atoms. Graphene is 200X stronger than steel where as carbon fiber is only 2-3 X if I recall.
Here are some details from wiki:https://en.wikipedia.org/wiki/Graphene

Graphene has many extraordinary properties. It is about 200 times stronger than steel by weight,[SUP][3][/SUP] conducts heat and electricity with great efficiency and is nearly transparent.[SUP][4][/SUP] Researchers have identified thebipolar transistor effect, ballistic transport of charges and large quantum oscillations in the material.

Carbyne
Carbyne: A new form of carbon that?s stronger than graphene | ExtremeTech
[...]carbyne is about two times stronger than graphene and carbon nanotubes[...]
[...]The researchers found that carbyne is massively strong (6.0–7.5×107N∙m/kg, vs. 4.7–5.5×107 N∙m/ kg for graphene), very high tensile stiffness (it’s almost impossible to stretch), fairly chemically stable, and yet surprisingly flexible.[...]

Well they asked what is next and since they have made in the lab graphene sheets and are working on production methods but carbyne is still only theoretical, I would postulate that carbyne would follow graphene.
AS it is, we use carbon fibers to bear the load, nothing says we cannot use graphene ribbons instead. I think it would resemble spread tow fabrics

Seriously though.....what are bicycle frames today (or even 30 years ago) lacking which all this high-tech gimmickry will fix? The bicycle is a mature technology. Adding gimmicks and high-tech whatever, doesn't improve them; just makes 'em more expensive (As if we need that!); often more fragile; and takes away from the real refinements which could be made if builders were concentrating on the basics instead of always trying to adapt the latest and greatest technology for no other reason than because it's the latrst & greatest.

Cycling companies don't want stronger, they want lighter. The sooner you have to replace a $10,000 bike that cost $300 to produce, the better. Carbon fiber is a pretty amazing material. They can reshape it every year to look "new", it's light & it allows for directing strength into certain areas of the bicycle. It makes great wheels, hubs, saddles etc etc. & a large downtube is great for advertisement. I think CF is here for a while. Ti bits might be replaced with the latest greatest materials & frankly, i think retro materials may find Vogue from time to time.

According to my Webster's Encyclopedic Unabridged Dictionary, Carbon Hexachloride comes after Carbon Fiber. It smells like camphor. Vick's may be the next big bicycle company!

I'm assuming with all of these fancy fibers, the resin is probably the limiting factor?

I doubt for bike related hardware, resin would be a limiting factor.

Certainly a case of 1 + 1 being more than 2. As an architect I see the resin's role as sort of "continually bracing" the carbon fibers.

Would they be sold at an all night wicker store?
Some places sell bikes made of bamboo. I'm guessing to cash in on the whole "green" market segment. I personally wouldn't want one, even if it is a sustainable resource. Either that or when Gilligan was rescued off that island he and the professor became entrepreneurs.

I bet an epoxy without fibers will be next because it would be soooo easy to produce. (Not that it would be better)

I think that is oversimplifying, given that without the laminating resin, the carbon threads/fabric is ........... fabric, not effective in compression or lateral stiffness. Great in tension maybe - but it is just a limp fabric without the resin. I think the importance of the resin is often undervalued in these conversations. Assume more advanced resins will make the overall composite more fatigue resistant, UV resistant, heat resistant shrink resistant, etc...

Probably a good call. Definitely talking (speculating) above my pay grade. Fun to think about though. When I was in college 20 years ago my professors speculated that the next big think in building design would be plastic/composite beams. Not there yet though.
