G-boxx

[jeremyb]

Anyone ridden one of the new G-boxx equipped Evil Imperials?

[FlipSide]

It's a prototype...and I'm not even sure if it's functionnal or not.

They're 100% prototypical right now.

the Imperial 2013i is supposed to give an idea of the time frame.. a full decade away.

Hopefully they're under promising to over deliver.

EDIT: Nicolai should have a G Boxx equipped bike. Search pinkbike for it. I thinks its a functional prototype.

Supposedly the whole 2013 thing is just saying that it's "ten years ahead of its time" or something silly like that.

[cookedbananas]

those G-Boxx things scare me. they're so freeking built, and look like they're from a motorcycle or something. cool idea though

Nicolai's Nucleon TFR (G-Boxx equipped bike), will enter production later on this year.

It was slated for production sooner, but Karl is very picky about the design, and will not release it untill it is perfect. When it's available, expect it to perform flawlessly. There is many years of research behind this product and it will show once it's released.

As far as Evil's 2013i, Dom from yodo will haev a better idea than me.

Hope that helps,
Cheers,

The Evil Imperial is ot in production yet, if it ever is it will be in 2006 at the earliest

I'm a little aprehensive when I look at that bike...I mean most street rig run 1-8 speeds at the most...that thing looks like a tank, I would be hard pressed to believe that there is an advantage to the weight gain, the rollohf hub already does what they're trying to do, and it's heavy as fuck...a conventional drivetrain is not all that great, but ti weighs very little comparitively...yes, I'd imagine like the Rolohff, you can shift any time, mashing or not, but the weight again concerns me, as does anyhting that obtrusive to the BB shel on a "street HT"

[Shore Rydah]

it would be ok if it was a fully


and it had a rollhof , it wouldn't need any chain tension device.

Heres a few points about that 2013i prototype. Just to clear a few misconceptions.

The frame, with cranks, sproket and G-Boxx weighs in at 11.9lbs. A complete bike should weigh in from 26 to 36lbs, depending on build. So it is in fact, not much heavier than a standard set up. It's only about 2lbs heavier.

Also, the main purpose for any Evil hardtail is not typicaly street. They are used frquently for trail/DJ/DH/FR use, and this will benefit all types of riding. for street riders who want a simple SS set up, the Imprial will still be available, so don't worry. For those who ride trails still, bet your bottom dolar this is gonna make things much better.

G-Boxx has potential. I'd like to see a BMW with horizontal drop-outs and a rohloff hub (either at the main pivot, or in the rear). I don't think you'd even need a chain tensioner since the distance between front and rear cogs would remain constant.

The front ring casing on the Nicolai looks like it would get pretty beat up from hard hits, and I dunno about having an exposed chain running through a 'sealed' transmission.

These are pretty minor things, the basic concept is really cool

Ok well, it says on the site that it's aimed at street for one..."we decided to debut thistechnology in the form of a street specific hardtail frame set..." can't get much more difinitave than that...that section of the G-boxx that hangs down is gonna be a real bear to protect, and will probably take alot of abuse...

secondly, it's an Aluminum bike which is not too good for a HT IMO in the first place, but the whole Idea of Using Aluminum as a way to save weight just went out the window...you could have a .243 set up to ride street that would weigh in at 35 pounds and it would be steel which is Infinately better for making HT's...26-36 lbs, and it's crapluminum??? basicly you're saying that it weigh's so much that a steel version would just be impractical...street rigs a simplistic machines, the best ones are BMX's and they don't even have discs...now were getting into motor bike tranny's and all this heavy gadgetry on things that have been droping them to save weight and add a certain amount of reliability/peace of mind...

I realy like the Innovation and departure from the Norm, don't get me wrong, it's great that there is some forward thinking goin on, and that the concept is realy progressing, but IMO, it has no Real advantage over a Rolohf...

Proprietary mechanisms are a boon in an industry where people change parts and pieces to fit their style...the fact that to replace it we'd have to go throuh Imperial Or Nicolai ALONE concerns me, I like options so as to keep prices competative...basicly you're creating a forced market, I'm sure it is well made and engineered, and I don't mean to sound acusing, but it's like the I-pod..."gotta have one...the battery only last's 18 months and then you have to pay us more or you're out of luck..." I don't think Imperial is that kind of company, I've never heard any HHorror stories about them, but I get nervous when someone has the power to charge you whatever they want because there's no alternative route for us to take...

Good looking, well made I presume, why not make it a FR/DH full-squish rig...that is where the technology is needed...not to mention that as was earlier stated, an OPen chain going into a sealed unit will be realy problematic IMO, you'd need to be able to open and service it all the time, Look at MX bikes, they have an exposed chain wheel and they do just fine, no crap getting into the tranny etc...just something to think about...

No Worries

There's something that looks too weird on that thing. I don't like it.

The replaceable chainstay thing is cool though, but I don't thing people would really need it.

First let me start by giving a synopsis of what the 2013 and g-boxx is all about.

G-boxx is a very complete yet versatile standard that I developed in 2002 around a modified Rohloff hub, which eventually became the "g-boxx standard" after Karl Nicolai and I talked about it a bit. He designed his own bike (TFR) around the standard, and I designed my own bike (2013i) around it. Karl Nicolai manufactured the Nucleon TFR and also welded the gearbox section into the Evil 2013i show bikes. The only thing that is the same on the two bikes really is the gearbox unit and the housing/ interface that I designed. The hope is to show the versatility that is possible with a system LIKE this. Karl also built a web-site for the standard, www.g-boxx.org. We will be updating info on this site very soon, so stay tuned to g-boxx.org, and the Evil site for more info.

Over the next year, we will test the two bikes side by side to learn more about enclosed gearbox systems, and the structural and dynamic concerns that surround them.

Think of it as a big science project headed up as a partnership between e.thirteen/ Evil and Nicolai aimed at bettering bicycles for all time.

I would doubt that the system will be refined enough to sell production frames within the next couple years, but money can change anything!

This was not the first gearbox system ever put in a bicycle, but to our knowledge, it is the most well defined, and the first to be built around a "standard" of any type. It is not the end all be all, but we hope that it is a step in the right direction. A step towards this mystical "end-all-be-all" The end goal will be for someone to produce a working ratio adjustable transmission system designed for integration into bicycle frames. This task will take a lot of $$ and time. It is not an easy task, but someday it may be done, and we will support it.

You got it, it

In reply to the last paragraph in the post above:


Actually, Nicolai built the TFR for that exact reason. The two bikes are really VERY different.
*The 2013i uses a gear driven primary, the TFR an enclosed chain driven primary.
*The 2013i gearbox is completely sealed, the TFR is not.
*The 2013i has a completely external chain, the TFR has an internal chain.
*The 2013i is a hardtail, the TFR is a suspension bike.
*The 2013i is made from 6061, the TFR from 7005.

The big similarity though, is that they both use an identical center section design, and the same actual gearbox unit. This is about as "real world" as it gets for testing, and I am proud to be leading this project.


Later
