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.

[-] pyre@lemmy.world 0 points 6 months ago

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

Carbon fiber has very limited lifetimes when used for something with a lot of hard impacts, so if you're not sticking to smooth surfaces the bike can literally split apart with little warning

[-] Kecessa@sh.itjust.works 0 points 6 months ago

Eh...

Modern mountain bikes? Hell, they make car and motorcycle wheels out of it...

I Googled "motorcycle carbon fiber wheel" and autocomplete immediately suggested adding "failure" and doing that search has endless relevant results

[-] Treczoks@lemmy.world 1 points 6 months ago

I don't think this will work on the long run.

First, the hold on the rim must be very tight and precise or the wheel will wobble like mad.

Second, such a tight hold will be very sensitive to any kind of dirt, so it has to be sealed.

Any seal tight enough to keep extremely small dirt out will cause loads of friction.

Tight seals in general is not an option, they exist en masse with e.g. hydraulic cylinders. But for them, the friction is basically a non-issue in comparison to the overall power budget. But I cannot imagine an even halfway free wheeling wheel that will not break down after getting in contact with a bit of sand.

This is the first step to having magnetic wheels become a thing. We know canonically Jim Kirk's motorcycle uses these, so it's definitely mainstream by ~2250.

Honorable mention: the Bell Riots happen September this year, and it seems we're on track for those too

i never realized until this moment that the meme showed them putting a stick in the wheels. i always thought they just happened to fall off.

[-] lseif@sopuli.xyz 0 points 6 months ago

then what did you think the point of the meme was ?

I wonder how many times someone has learned something new and then the first reply they read was a link to that comic and they discovered that, too?

As far as I can tell, this product never panned out. It was backed by 132 people to cover 150k GBP in 2017. It was called the “Cyclotron Bike”.

Wait, I'm confused. Does it have tires or is that just a big ring of plastic?

[-] dexa_scantron@lemmy.world 0 points 6 months ago* (last edited 6 months ago)

From the video it looks like the plastic rings are casings and the wheels are inside them, and the wheels poke out at the bottom. Seems dumb to me.

You can kind of see it here but it looks like they're intentionally hiding a good view of it with angles/lighting:

What happens when you ride through mud?

[-] Opisek@lemmy.world 1 points 6 months ago

You ride into the mud. Not so much out of the mud.

Eh, I'm waiting until the seat is simply hovering in the air without any bars

[-] Edgarallenpwn@midwest.social 1 points 6 months ago

Why do we need a seat when we can just Crazy Frog it

[-] creditCrazy@lemmy.world 1 points 6 months ago

Can I at least keep my pants on or is the nudity required to make this work
