Where the lowest gear is direct drive 1:1 and then each additional gear is higher. The idea is you start 1:1 and tune your cog-chain ring combo accordingly. The old Sturmey hubs like the AW and FW had direct drive in the middle, with lower gears being reduction.

SirMike1983 thank you for the explanation. I missed the description tcs had provided earlier. That's the trouble with reviewing C&V on my phone.

Still one of my favorite bikes in the herd. A 1983 curb find Nishiki that I renovated with an SRF 3 speed and bull horns. Super comfortable ride and the gearing is just right if I don't encounter any big hills.
It's the bike I used to take with me in the truck before I retired from the road.

I've got a lead on a Super Course! I'm hoping it works out, this thread has been a big inspiration and rekindled my desire to build a bike in this style. I plan to build a set of 700c wheels with a SA rear hub. Looking for front hub suggestions to match the aesthetic. I'll be using Sun CR-18 rims.

This stuff is EXACTLY what I want do with my old BSA-thing.
You folks using modern bar-ends, I see S-A is selling one that has the correct pull for old hubs. Anyone have any experience? I was going to use a ratcheting Suntour just to try it but “indexing” would be more betterer.

Another one I built on a generic no name track frame. Sturmey Archer S3X. Riding fixed gear was a new experience for me, and the 3 speed made it doable, but when I had to cull the herd a few years ago to make space, it was one of the bikes that had to go.

They stopped making them, but I guess old stock is still around on the hubs. It works pretty well, as proof of concept. But I ride it more in town and traffic, so I switched it over to flat bars. The SRAM twist grip shifter for these hubs is kind of iffy, but it hasn't worn out enough to experiment with other shifters for the 5 speed hub, which works with a push rod, not a pull chain. It does seem to be a well made hub, though.

Would my Koga-Miyata SilverAce fit in here? Granted the drum brakes, fenders and locks make it heavier than some on here. It is 18.4 kg (40.5 lbs) as pictured. But without the front rack (1kg / 2.2lbs), frame lock (0.75kg / 1.6 lbs), fenders (0.8g / 1.7 lbs) and saddle bag (0.5kg / 1.1 lbs) this would be a 15.3 kg (33.7 lbs) bike. Some lighter tyres or a smaller rear drum would probably shed another 1 kg (2.2 lbs) or so.
But hey, it's a Dutch commuter bike. I need all that stuff.

...I did a similar thing with this track frame I bought from Nashbar, on an end of year closeout. At the time, it was cheaper and easier to buy an IGH with a coaster brake online, P5 made by SRAM.
They stopped making them, but I guess old stock is still around on the hubs. It works pretty well, as proof of concept. But I ride it more in town and traffic, so I switched it over to flat bars.

...the push rod control box is fussy about orientation. After some fiddling and experiment, this worked the best.
I guess I could have pulled off that fall over protector, but I got tired of messing with it, once it worked well.

Here’s a recent drop bar IGH built around an S-A four-speed FM hub. Frame is a 1973 Condor Italia:

I could make this thread go on forever with all the IGH conversions I have done for myself and others, so I won't do that, but I will show this one. 1986 Raleigh Bighorn that I put a Sturmey Archer RXRF 5 into.
I ended up giving this one to my daughter in law.

I really like this general concept of a 3-spd IGH drop bar bike. Keep the examples coming. I've started looking for a good donor bike to do my own.

Here's a few from my stable. 1973 Super Course with an FW modified to 3 speed fixed gear. Shifted with an old Simplex friction shifter.
1954-ish Robin Hood with a fixed gear 2 speed Bendix. Slop free hub.
Not exactly a lightweight, Rivendell Bleriot with a Sram 7.
Not a dropbar, but a hoot of a commuter, 1964-sh Dunelt Sports 2 speed fixed AW, aka, The Tetanus Express.
This is a 1970 Robin Hood Lenton Sports I got new in 1970. It has an alloy shell 1950 AM hub with a Cyclo triple cluster.
Early sixties Dunelt Fluer de Lys(sp). AW with 2 cogs, Huret Allvit, Williams crank. And Blumels.
Definitely not a lightweight, 74 Bitsa Sports.
There are a couple more but I don't have decent pics of them.

I recently bought one of these contemporary 4-speed thumb shifters: https://www.sturmey-archer.com/en/products/detail/sls40
I'm hoping it'll work on an FW/FM hub family, but haven't had a chance to test it out yet.

I converted a StumpJumper Sport bike to use an 8-speed IGH. To keep it as simple as possible, it uses a single chain wheel up front. It is nimble and fast, surprisingly so. I got lucky picking that frame for the project.
I put some drop bars on it but did not care for them, so I took them off. It was kind of surprising how many things had to be changed to go from flat bars to drop bars, and how much it all cost. It was a total waste because I went back to flat (North Roads) bars.
I once put flat bars on my road bike. That sucked, too. The frame geometry was not good for upright riding. Neither was the saddle.
If you do it, chose the frame carefully.

The only truly lightweight IGH I've built was a Sakai Champion 2 Duo-matic with mudguards & rack. ~ 23 lbs without the Conquest saddle and pedals iirc.
