53 gears?

You can put a derailer gears on a Sturmley/Archer internal gear hub. I
think there are a few manufactured that way. 3 * 10 * 7 = 210 gears.

Uh.... 53 is a prime number.

Sheldon Brown has a 63-speed: http://sheldonbrown.org/otb.html

Fifty-three would be a bit of a trick - that's a prime number, so it
would have to be 53 sprockets on one axle.

Bike or trike?

Here are some trikes with lots o' gears:

I think that Sheldon brown had something like that, I think it was
actually 63 it was a 7 sprocket rear, a 3 speed Hub and a 3 speed
chainring... 7 x 3 x 3 is 63. Considering that you can now find 12
speed hubs, 10 sprocket cassettes, and 3 sprocket chainrings, the
maximum now would be closer to 360 gears. To overstate the way over
obvious, shifting would be a bear..... Does this shifdt give us 247 or
162?

A 53 tooth chainring perhaps? I'm with your brother on this!

Yeah but that link is the one that I remember seeing, I just couldn't
remember exactly how many gears it had! My brother think it's stupid.
Well I just had to find it to prove to him that it does exist(sp)!

I believe this is right. By the way, a 53-gear bike would be difficult to
arrange, since 53 is a prime number.

Considering that you can now find 12

Well, you can't mate that 10-sprocket cassette to a 12-speed hub, anyway.
But it's worse than that. There are 14-speed hubs (Rohloff), 4-chainring
cranks (for tandems), as well as 2-speed internal gears for cranks, though
I don't think you could mate anything like all these together. The
Rholoff hub seems to have a threaded sprocket, unlike the Shimano which is
a splined sprocket held on with a spring-clip. This might mean that the
hub could accomodate a freewheel. Let's be conservative and only assume
you could squeeze in a 5-speed freewheel. That would allow

14 x 5 x 4 =280 gears,

but a more reasonable estimate would be with a double chainring, still
giving 140....

Hmm. Where are you getting that last factor of 7? A 7-ring crank?

Met a couple on a recumbent tandem.. the thing had over 80 gears!

3 on chainring, 10 on freewheel, 7 SA internal.

I believe someone now makes a 14 speed internal hub, so you got your
3, your 10, and your 14.

420 gear combinations, although I'm sure that there is some overlap;-)

Bent riders are proud of being bent :-)

Take a Sram dual drive 9*3=27 add a triple front 27*3=81 now add a mid
drive = confusion with 4 shifters.
