I was running a search on Google for bike parts, maintenance etc and came across a guy who made a 63 speed bike!!!!!!!!!! :shock:
Didn't really know if this was the right forum but as I'm making a single speed full suss bike up I thought I'd throw it in this forum.
Sort of an anti-singlespeed???
I took this off the site:
Anyone else seen any other mad stuff out there?

The O.T.B. currently sports a Sturmey-Archer AW 3-speed hub, with 7 sprockets, driven by 3 chainwheels: 3 x 7 x 3 = 63. When people hear that I have built a 63-speed bicycle, the first question they ask is "do you really need all those gears?"
The answer, of course, is "no.", but I don't actually need all the gears on a ten speed either. In fact, most of my riding is done on one-speed (fixed-gear) bikes. Nobody needs 63 gears, but it was an interesting and amusing mechanical challenge to put it together, and it does give a very wide range, with close spacing between ratios. There are proabably gears that this bike has never actually been ridden in!
Actually, I guess I was just ahead of my time, because a similar setup is now offered by Sachs, a 3-speed hub which is designed to take a 7-sprocket cassette. Nevertheless, as far as I know, I am the first to succed in getting 7-sprockets to work on a Sturmey-Archer hub!
Anyone else seen any other mad stuff out there?

wow try that with a rholoff (sp?) 14 speed hub and a 9 spd cassette. Thats 3 x 9 x 14 = 378! :S0

what about a gear box up front and then the cassette and gear hub. the possibilites are endless0

oh wow go on someone get onto that

My Hurricane Recumbent has 42
Sachs 3x7 rear with double chain ring (52 and 64) at font.
However the greatest I have seen in a production bike is the Greenspeed recumbent who have a Sachs 3x9 at the rear and a front triple giving 81 speeds giving 13 - 125 inches.
THe question arises as to where to stop........
Add a Schlumpf bottom bracket and you could have 162 gears, ar add an intermediate Rohlloff and you could give this bike a total of 1134 gears
A final option would be mechanically possible.........:
3x9 rear
Triple chainset
Schlumpf dual drive
Intermediate Rohloff.......
2268 gears!
What is the maximum, and where does it become silly?<b><i>He that buys land buys many stones.

when does it become silly???
anything after 8...i ride a hardtail0 -
ha ha. for most use i think a singlespeed is fine. especially for stuff like commuting and a fair amount of mountain biking
next time i do the forest of dean Fodca trail i'm gonna try and do it in one gear. the rooty uphill will be a right challenge but i'm gonna give it a go
anyone know what gear ratio the wierdo mtbers use for their singlespeeds?0 -
usually 32:16 to start with, I'm finding 36:16 a bit much for the mud and will go back to either a 17 or 18.0

I'm going to be running a 38;16 when I get my single speed full suss finally built up this week.But as for ratios usually a 2:1 is recommended as a start point as said above, 32:16, 34:17 etc.0 -

For winter mud and hilly stuff you might be better with 32:18. 16 is better on hardpacked summer trails (or maybe I'm just a wimp).0
