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

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.

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.

flag reverend (May 18, 2008 at 16:39) (Below Threshold) show comment
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...

with this design, can you shift gears while not pedaling?
  • + 0 props
flag oceen246 (May 18, 2008 at 7:21) (Below Threshold) show comment
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.
