thats freaking sweat.
no more spending a fortune on derailleur hangers..
it looks so sick compared to all the other gearbox bikes
with the exception of honda

id of thaught anyone who can make there own gear box would have a good taste in music!dono about this being vod but whatever its prety sweet
nice work putting the effort into building this, but it's amateur in comparison to the "millyard racing" bike.
i bet ya the derailleur is gonna be a bitch to take out if u have to, but watever it seems to be wrkin...
only problem i see is the sound and not sure how much pressure those pivots can take coming down off a drop -

yeah, he probably couldn't put it into production though, since honda would have a patent. but in a few years from now i bet companies will be all over that design.
There is already way better designs of this, and you can buy a seperate gearbox if you want to, but then you will need a specific frame to fit it, I think that Nikolai might have a full bike with a gearbox
i think its pretty good to be honest. for people like me who didnt fully understand who the gear box worked, this is a really good way for me to understand it.
This is not a gear box. there is still a derailer. he just moved it. benefit: shift without pedaling.
Like sich0015 said this is NOT a gearbox. Its a sick design but a gearbox does not use a derailleur, they allow you to shift without pedalling whereas this works like a standard mech. Still mad props for making it.
Although obviously not quite standard as you can shift down without pedalling, a huge benefit for racing as you enter slower sections.
Yeah... ummm just because it has a deraileur dosent mean its not a gearbox, in fact, the honda gearbox had a deraileur just like this one. Actually the whole honda G-box is shown here:

thats a very chron idea, low tech gear box, props on being the first one to produce it, at least the first that ive seen!
omg i love that bike id pay so much to get a hardtail set up like that so that u can get gears and have less derailer problems!
)
thats some amazin engineering, must have taken a while to make! pinkbike should have a BOD (best bike of the day) that would probably win it.
Does the chain that gays to back wheel not need a tenisioner or E-13 sort of thing ?
Nice Bike thats amazing

this is so sick man, making your own gearbox bike. you can even change gears while not pedalling, honda style man!
I dont get it ? What is the advantages with this kind of system? Why dont you just go on with the regular.
the main advantage is that you can change gear mid corner, halfway through some rough stuff or whilst in the air, you dont have to be pedalling to make the shift.
I'm not an enineer, but as I understand it, the chain line also reduces or eliminates any drivetrain induced stiffening of the suspension. With the drive gear located at a point where the arc of the rear hub means no change in relative distance, there is no need for a chain tensioner either. Personally, I think I'd want some sort of cover over that constantly spinning buzz-saw... hate to have my right calf brush up against it at speed...
it`s like a honda bike.... isn`t it?!..... I would like to understand more aboute it....cause i also see no advantages in this case...with gearbox openned... but congratulations.... you gotta work it hard to do all by yourself...
[Reply]
Oh yeah, and wouldn' the chain get in the way? Its really high up. Would you're legs not get caught on it?
loving the idea but isnt pedalling going to affect the rear wheel travel? not so keen on the single piot idea however i apreciate they are probly the easiest to make
i cant believe what some people comment on, like saying its shit or rubish. just the fact that some one even has a go at creating a bike is fantastic ugly or not. i think some of these people should spend more time on their bike than on the internet commenting in a crap and uninspiring way.....
get on a bike and ride
g

the people hating it or disputing its vod title please get a life, hes done it himself and it works, must have taken some time to do.. are they 151 boxxers also?
Props for u to build ur own bike and gearbox man,but i dont think it deserves VOD..sorry..and thst kind of gearbox aint nothing new, but making it most have taken u a LOOOT of time!props dude
Nice idea but it's not a gearbox now, is it? It's just a standard derailleur and cassete mounted in the frame. Not exactly ground-braking technology but not a bad idea.
The best use of existing technology that i have seen. I would put some fenders or some thing around the derailer to keep the crap out.
I don't think you can because it's still using that derailler concept. So while you're trying to shift to another gear, the chain is still going to be on the same gear and that until you start pedaling. So it doesn'e have the advantages of a conventional gearbox where you can just shift gear without pedaling and you still have to run maintenance on it because it's using a derailler to shift.
This said, it still have the other gearbox advantages, like you don't need worry about the derailler hitting a rock or something else and just snap off. The use of the chainguide or chain tensioner is pretty useless as the chain with always remained tensioned.

yeah, but it still means that the bike as to be moving, while in a conventional gearbox, the bike can be fully stopped and you would still be able to shift.

thaqtgs really nice you will make alot of money and another good thing is iff you buy that when its patent you could save alot of money because it would be WAY harder to bust a derailer and for a good derailer your looking at 150$$-200$$...props on that man
cant imagine how expensive one of those would cost, how much spares would cost and how difficult it would be to get hold of the spares
[Reply]
Honestly i think its awesome you made it, im just not a fan of gearboxes, i like standard derailers.
[Reply]
i agree it looks like if you were leaning hard you might get tangled up...is there a way to put a guard the length of that long chain, or maybe put a part of the rear swingarm further out to protect it?
[Reply]
Class idea tho

Spoko rower z dobrym systemem. Ej ludzie z Polski, mówcie po Polsku !! Umiem nawijać po angielsku i to bardzo dobrze, ale to niech zagraniczni uczą się polskiego. Patriota.
to nie jest Polska strona, a Polski nie jest jezykiem miedzynarodowym, wiec pisz po Angielsku/
this is not Polish site and Polish isn't international language,so write in English

The bike is perfect although i would suggest you reinforce the headtube, cause from my point of view it looks kind a weak and probably would break.
NIce, but it looks alittle to complicated for me, and i dont think many bike shops wuld knwo how to fix that
why? Its a derailer,its inside the frame...im sure any compentant mechanic could figure it out....
Sweet BTW!
Sweet BTW!
how the hell is this bike poorly designed.
its one of the best ideas iv seen in mountainbiking the fact the the derailer is so protected and the you can shit down without pedaling

I was just about to post that!
Honda's is very similair,
But the gearbox is slightly slower, and also contained in a 'box'.

if a gearbox allows you to shift w/o pedaling, then why are they pedalin while they show it changing gears?
like the idea and how a under company have built it but still think my mate steve milyard bike is better, but still a nice bike, props to builders
[Reply]
That is so awesome; I would love to have a gearbox bike especially one that will shift while not pedalling.
Ironhorserider, watch the end of the video. They spin the back wheel and shift; the cranks are not moving.

personally i dont really like it how hard must it be to repair it or just put your chain back on but still its really ingenious
The transmission drives a chain which drives a sprocket on the pivot axle. Then, another sprocket on the pivot axle drives the rear hub.
The distance between the rear hub and pivot of a single pivot does not change so there is no chain stretch.
Personally I think bikes like this are the future of MTB, I really hope that the idea of putting a derailer and cassette on the frame of the bike does not get patented. A high center single pivot with such a drive system gets rid of two of the main problems with high center single pivot (extreme chain growth and pedal bob) while maintaining the simplicity and good axle path of a high pivot bike.

so stupid there's really no point to this invention. wow its probably like 15,000 and you van buy a regular and better bike for 2500 or some thing I think there being pretty dumb
You really don't get it do you?
He designed and built a an innovative full suspension bike.
Second of all, a 'regular' bike?
People said that bicycle suspension was a silly and expensive fad years ago.

the song is totally wrong for the vid, if it was instrumental it would have been ok, nice craftsmanship tho
Just a question, Wouldnt the shock possibly rub against the gearbox? And what if something gets in the tire and just flings up and gets caught... not really the smartest thing and it would be so hard to fix it you got a problem with it... but still its pretty cool lookin 
i think its people like that who keep things rolling in the bike industry anyway honda arent making bikes now so it opens the door for other companies who could put it into production when the time is right.i think it shows off the designers potential for future designs i hope to see more soon.
Its cool to build your own bike and you did it in a very creative way. Shifting seems clunky though and the frame looks like it weighs 20lbs. Hope you like riding it!
its cool and all but not vod material+i can see those messing up on you and it being a bitch to find the right part to fix it
[Reply]
all they did was move where the derraileur and cassette while cleaver not really a gear box gear...gear boxes more work like a transmission thats why they are diff than a derraileur so im not impressed defiantly not VOD material
The Honda "gearbox" is "just" a derailleur in a box with a cassette... they still call it a gearbox.
i had always thought of putting the derilluer on a different area because it always gets smashed but wasnt sure how to do it..GREAT JOB...sick
thats cool i wood like to know more about it tho it looks wierd but a good setup just rebuild the frame bcz it looks kinda bad but sweet

How is that a 'gearbox' bike?? Its just the same as a conventional gear system turned upside down and at the other end? And its not even in a box. Looks awful aswel.
frame kinda sucks.
look at when he rails the berms.
the bottom part of the frame past the bb will hit the ground before the shock even bottoms out!
thats how it looks to me anyway.

love it mate,
my dad did soemthign similiar, but he got a motorbike frame, added pedals, but kept the motorbike gearbox, and we where like, OMG,. you can go 60 on it ?!
nice dad,

nice dad,
it didnt deserve vod, but it is a pretty sick idea, then u dont brake ur derailer off as easy, and it wont go up in ur wheel and around, like it did to me
everyone that says this is stupid or shouldnt be vod is an idiot.. you are missing the whole friggin point. THE GUY BUILT HIS OWN BIKE. He wanted something different and he got it.. Anyone that buys new parts or tries new parts can't say shit.
[Reply]
all it really is is a cassette and derailure inside of the frame.
I personally would ride this. Heavier to ride this "gear box" instead of a derailure, Harder to fix than a derailure because the derailure is open, More suspension options instead of having to run a single pivot.
And in regards to TYPX post. My friend lem has built a 7inch freeride fully from scratch and now hes building a dj/street ht, Im not saying what this kid made isnt impressive but theres no point to the gearbox and you gain no efficiancy, which is the point of a gear box.

for all those that run gears and said it wasnt that great, tbh you want to buy a gearbox bike if you could afford it, this guy went out and did his homework, and now hes one very happy owner of a bike of his own work!
i say props to the dude and lets hope we get more innovative people out there! i like the frame tbh, but i dont like the forks thats all i have to complain about

Thats amazing man, look like it took a lot of thinking and planning to get it perfect, and you did a damn good job. Aside from that being the baldest rear tire I have ever seen, Props.
