This is what we came up with.

holy shhit that weighs only 8lbs!!!
It's light because its a carbon frame, stick it on a regular bike and it'll be heavy as feck. When sh1t like this gets as small or as light as a regular drive train, then we'll buy into it. The whole drive train of bikes is very crude, we need sh1t like this, but it needs to be lighter, smaller and easier to fix and setup, you'll need an F1 team to fix this.
check out the rohloff hubs(finite number of gears but you can change them without pedaling),they are "simple",you can mount them on everyday bikes,it's pretty light(considering that you don't need chain rings nor derailleur) and it was tested pretty good for example Super T uses them(used them all the time) and the Flowriders(at least Dan Cowan 100%) and they give lifetime warranty
The easiest way to under stand the sun gears is to think of it like a ratchet wrench. If you only had one wrench, then when you crank the handle forward, you rotate the socket. But then you have to return the wrench to the starting position before you can rotate it again...
put on an additional wrench, and move them in opposite directions, and you get constant rotation(One rotating the socket, as the other is returning to the starting position)
In this explaination, the "Socket" is the equivilent of the out-put drive ring.
Hope this helps you understand it better.

That's one interesting / innovative design... if people don't do stuff like this you would never get anywhere.
That being said, I'm not so sure as to how practical it is... it seems to me like in order to get rid of the derailleur they are putting in a much more complicated system that will be a lot more expensive, harder to fix, and cause more problems than a derailleur. Only advantages I truly see to this over a derailleur is the possibility of a lower centre of gravity on the bike (because of no chain rings) and possibly the infinite number of gears (although I've never wanted more than 8 gears, 9 speed is way more than enough).

one of the cool aspects of a gearbox or internal hub is that the chain can't ever skip or grind or get caught between gears. not that you need infinite gears, but its cool to be able to change the ratio smoothly like a volume button. you can shift standing still and not worry about having to pedal out the gear change. i would like to see the technology go into hubs that fit any bike, rather than only one frame, but what a hell of a start for this guy. cheers!
the beginning of the end of the deraileur is here. (mind you....i'd love to have an 8 speed internal gear hub)

surely on the bike its on, shits gunna get all inside it? cause on that proto he has there theres no gaurd to stop that?
[Reply]
Im sure you could and im almost in fact certain that that hole box would be water tight and have probably some sort of lubricant in the box its self
damn i cant even understand it but it sounds cool...it'll take a good while before it makes more sense do buy one of those instead of like a deraileurs...but you need guys like him to keep goin forward. yeah if he was the one postin the vid id be like props man your the best but yeah

Maaan, that guy is awsome!! i mean really, coolest guy in the world!!
he's such a genious!, and he managed to draw the plans out in his bedromm which is pretty ace.
Whatta guy

The Ride, by Ellsworth, features the NuVinci CVP transmission in a rear hub, looks a little tidier than this one, and a bit more reliable as well perhaps. Go check it out.
this would work well, duralers seem to hate me they always break and only on my bike to. none of my friends
Not only is that guy smart as hell, he rips too. It's funny/humbling to watch him go up a hill on a kona stinky as fast as he goes down it.
i want to cheque out the NuVinci CVP transmission it looks dumb i dont now i juste don like it but this transmition is a great idea well its amazing
[Reply]
this idea is pretty genious but compared to the honda g-cross rn-01 design it seems to complicated but this is awesome and i hope it takes off for the guy he will be rich
[Reply]
i saw that and thought the same thing. but i think it would, he couldnt make that big of a desighn flaw.thats a super cool fram and i bet it will cost alottt
if youve seen the other lahar bikes they have realy thin parts aswell but somehow he seems to make them strong. the bottom chainstay on a lahar M9 is like 5mm thin
SO much better than the gbox, I am so looking forawrd to the day when derailuers/mechs are a thing of the past and we can finaly hit a narow line through some rocks without hangon a 100 bucks off the side of our bikes to get ruiened on the trail
[Reply]
thats sick, a really great design but like people said its super complicated nd would take narly an F1 team to fix it and at this point it still looks fairly heavy. that being said the idea of it is awesome. thers no chain slip.
now try not to kill be but y not go with the idea that the honda bike had and simply sitck the deraileur into a box in the frame. its been proven to be practical. obvisouly very simple and could provide alot of the same advantages to the frame...lower center of gravity and less unsprung weight to the rear end

I remember when the driveshaft idea came out and the dual drive bikes... This is amazing. I like it better than the gearbox design better than the Honda design, but the frame is ugly!
wow, to all you guys bashing, you could not do that at any age, oddly enough i understood all of that but i still dont get algebra, i only hop i can be where he is when i am his age. PROPS
