Rather misleading since the concrete isn't even structurally integral to the bike. It's more like a rebar bike that had concrete poured on it.

- ddkto 4y agoI suppose the technically correct term would be reinforced concrete bike
- cptskippy 4y agoI would say "I covered a bike in concrete" would be the most accurate title.
- stingrae 4y agoto be fair, large amounts of the frame are not just merely covered in concrete
- cptskippy 4y agoYes, and the entire thing is either reinforced with rebar or structurally dependent on actual bicycle parts. You could argue that the rebar reinforcements, if welded together, would make a sufficient frame and the concrete is primarily acting as a bonding agent.
- version_five 4y agoThe same thought went through my mind watching it, but you could say the same about most (many?) concrete structures. Someone with a structural background could explain better, but I believe the rebar and concrete provide different kinds of strength, like concrete is compressive strong (and keeps the minimal amount of rebar from moving around and bending, while the rebar keeps the concrete from cracking. Even for the bike, it wouldn't be the same structurally if they just wired up a rebar frame
- pwg 4y ago> but I believe the rebar and concrete provide different kinds of strength Yes, concrete provides great compressive strength, but is not very strong given tensile loading. Rebar provides the tensile loading support that concrete alone lacks. See: https://en.wikipedia.org/wiki/Rebar https://en.wikipedia.org/wiki/Rebar
- TheDudeMan 4y agoYes, but it doesn't matter for a bike. Riding it is not going to crumple that amount of rebar.
- stergios 4y agoThe front left fork failed. You can see the crack in the video as he is riding. The front fork has a bending moment as well as compressive force. When the bending force was applied the concrete failed and the rebar did not. Overall, I really liked this as an art project. I'm not sure what the artist wants to communicate with the bike, but I found it very satisfying.
- JKCalhoun 4y agoI'd like to think they're reminding us why we don't make bikes out of concrete (but we can!).
- debacle 4y ago> I'm not sure what the artist wants to communicate with the bike "I paid a lot of money for an architecture degree I'm not using."
- 2muchcoffeeman 4y agoHow much of this can you just chalk up to using concrete and just copying the design of a normal bike? This is a fun art project but doesn't seem like much more. Sorry for being negative about an art project. I think I was projecting my own biases, but it sounded like an engineering project and then I didn't learn anything.

- gpt5 4y agoIt seems like they could achieve the same results by pouring concrete around a real bike frame (instead of build a bike frame out of rebar).
- Kaibeezy 4y agoThe combination with steel is what gives concrete its power. It's a composite material created by the two things together. Concrete surrounds the steel frame and penetrates it. It binds the steel together.
