CeramicSpeed Drive shaft

[743 roadmasterParticipant]

the possible gearing is impressive
would like to give one a try out.
still prototype, but one heck of an innovation.

That would be a real game changer. There have been previous attempts at shaft-drive, but nothing ever caught on. This look very interesting.

Cool, it would be interesting to see how it handles a 200lbs man, giving it warp speed 9 up hill, like the guy in the first clip said. Would it take all of that torque?

Don’t get your shoe lace caught in that, haha.

Back off Barbie!

I had the same thought.

The aluminum ‘gear’ should be able to but they are using ceramic bearings.

As you all know ceramic is hard and brittle.
A ceramic bearing does you no good it it gets chipped.

Its good that they are trying something new…Very good design…

One problem I see is if those carrot graters chip a tooth, you would have to replace the whole hub…It would be expensive…

I stand with feet apart and let my balls hang free...Manginas dont have balls...See how they stand and sit at the whim of their masters...

I see a weakness here, the cogs only touch at a single place, and are very tiny. And it is fully exposed to nature.

-these cogs will wear more quickly than a chain (more conact area, less strain on material)
-This, as well as chains, are likely to catch dust and dirt and rain water. (don’t tell me this thing wouldn’t be greased…) it would need some cover.
(worst enemy of a drivetrain is the mud flying back from the front wheel right onto the front cogwheel, and mud from rear wheel getting stuck everywhere. (There are some belt-driven bikes too, for abusive conditions ie. biking in mud, but not widespread.)

-Basically any hub with gears inside, can do the same, but no parts exposed to nature, except one thick reliable chain.

Great post, that bike is very cool looking and I’m curious to ride one and try it out. He said it’s a prototype though, this design may never see mass adaption. Really cool though.
