    Imagine designing a bicycle without triangles. Every joint needs to be overbuilt, because there’s no structure from the geometry. But you make sure it still has a top tube, so its just as hard to mount and dismount as a normal bike. Incredible!

      Right? Who would be crazy enough to do that?

      Next you’re going to tell me someone will make one without a top tube?

        Hey, look here buddy. You can’t be your own comment thread and post all the plausible responses yourself like that. You’re putting all the trolls out of work.

        doesn’t that prove their point? they all look overbuilt, as the original commenter said.

          Carbon fiber, aerodynamics…

          For this one it’s used as suspension (not carbon fiber)

          Not that rare in old mountain bikes either, pretty sure my old steel Raleigh was similar

        The meme shows only bikes with flat handlebars, like commuter bikes intended for transportation.

        Every bike you posted are high performance racing bikes with specialized aerodynamic handlebars.

        Different priorities. Triangless bikes with a top bar is not a good idea for commuter bicicles like the ones in the meme.

          I still showed that it’s perfectly possible to build a bike without a seat tube, hell I’m sure we can find 90s examples that weren’t high performance bikes.

        At compressing part of bend. If I remember correctly, carbon fibers are good at handling tensile loads and terrible at compression loads.

      Nah, but that tube is a little lowered, enough to make a difference.
