In the 1980s I found an old Schwinn bicycle that I restored to the best of my limited ability back then. The bicycle had a Sturmey Archer three speed hub connected to a single speed drive train. While working at a hardware store that also did bicycle repair, I found a three gear external sprocket that was made for my Sturmy Archer three speed hub. I then changed the single chainring crank to a double chainring crank set. Then I fitted this beast of a bicycle with rear and front derailleurs, time trial aluminum alloy Cinelli handlebars with Modolo Kronos brake levers and road her until one night while giving my friends on BMX bikes about a 3 to 5 block headstart, I caught and passed all of them before the finish line. Then when I got to the finish which was Woodhaven Blvd., some asswipe female driver decided to make a right hand turn without using her turn signal. Needless to say I crashed into the dumbasses car and unfortunately wrecked my three speed Schwinn that was converted into a 12 speed. I sure do miss that bike, I nicknamed her "the Tank"!!!!
Thanks for this video. I grasped most of it, and I'm going to watch it again until I really understand it. These hubs are absolutely brilliant. The fact that they're so reliable and bulletproof speaks to their engineering and quality. Simple and elegant. I've owned and used several, and I want to understand them more.
I have a bicycle from the Netherlands that has a Sturmey archer 3 speed on it. Date stamped 1960. I've never serviced it. Just added some atf and I've ridden hundreds of miles at this point with no issues.
Always wanted to know this. And now I half understand it. Maybe another 57 years of life I will fully understand it. But by then I don’t think I will care anymore! :-)
I remember as a 12 year old earning extra pocket money restoring bikes that had been dumped. I dismantled 4 hub gears before I finally understood how to repair and reassemble them. I got known locally as the person to see for bike repairs.
I got a problem with my 1980's SA 3 gear hub. It doesn't engage idle when walking bike(pedals are spinning). When pedalling I can feel force transmitted to pedals when I stop. I've have replaced chain, oiled hub, replace pin chain. Still no results. Bit hesitant to open it up.
@@kamilpotato3764 Here is your answer after two years. You need to open it up. You have got problems with the ratcheting pawls or something is jamming the mechanism to act as 1 unit which makes your hub turn the pedals. There is also a slight chance that debris is gumming up the gap between the hub and the sprocket. If this slight chance is correct you can repair it by simply cleaning the gap but you will probably have to take the chain off for this and at that point why not service the hub too? If you don't feel confident you can visit the local bike shop, it is their job.
I have seen the go for crazy money on Ebay for just the hub...and all the parts to go with them are just as much...one was 300 for a 50ies model 3 speed..went to the dump a week later and found 3 of them but not old ones...Anyone looking for one or parts just go to the dump around spring cleaning time..
Just to complicate matters further,I have a 5 speed hub that I built onto a 27" alloy rim,but kept the double chainring & used the rear mech as a tensioner. Needed 3 gear levers though!
And the older ones are more durable then the new stuff out today...figures.I got chrome parts 30 to 40 years old that still look new while a year old bike left outside is completely rusted...they don't make anything like they use to..
Most anything chromed left outside will rust quickly. It has to do with electroplating and UV radiation. I'm a retired ASE master tech and I've seen 30 year-old simple chrome plating on pushrod ends that have never seen the light of day and they're pristine. But UV radiation will break the valence bonds between the chrome atoms and the nickel atoms underneath (all steel and iron must be nickel plated before they can be chrome plated) and soon the water will begin to rust the nickel and iron underneath it. Car makers, back when they had chrome plated steel bumpers and trim, used to put on three layers of chrome plating and still they would rust after about five years: tiny spots here and there, hardly noticeable until the water began to tunnel through the steel underneath. I'm sure you've seen the result.
Yep, Planetary Gears baffled me as well when I first saw them. I saw an excavator on a reality TV show break down years ago, and I watched them open up the 3-stage drive unit... and I was hooked! I then found the 14-Speed Rohloff Speedhub, and had to know how it worked. It showed me just how little I really knew about mechanical engineering...
Stermy-archer 3 speed hub, 15 years of use, 400 miles a month, The only problem, The small chain from the hub to change the gears begun to fail, Replaced the thinn rod with chain, Problem solved. The 3 speed hub was still in good condition when I passed the bike on.
I watched this video because I was impressed with my “new” 1956 Schwinn Corvette. I wanted to see why. It is a heavy bike and I found that my low gear is almost like a double low on an old car, compared to my 1979 Schwinn Collegiate. Both are 3 speed Sturmy Archer and they look the same. It must be a different gear ratio in the hub. I do like the one that comes Corvette and I think it is better for a heavy, lower to the ground cruising bike.
i think I see why when in "Neutral" (here 'Normal") gear it would inevitably pop out of gear when pedaling hard, resulting in bruising my gonads on the crossbar. I tried adjusting it many times, as did a Schwinn dealer. seemed just a limitation of the design, at least back in 1958. I was glad to finally graduate from that to a motorcycle.
Yeah...the new epicyclical hubs from Taiwan or where ever S.A. got sold to just aren't up to the quality of the original British hubs. They look good but just don't quite work as well. Their front drum brake units and hub generators are excellent though.
I believe Sturney had worked for a Manchester who had a US patent on a fixed gear three speed hub. Years ago I saw the patent drawings years ago I believe it was in the year if 1908.
from what i can make out to simplify , its a complicated way of using the diameter of the central hub ?? so gear 1 can never be any better than the widest point of the hub and top gear (3) is never any better than the smallest gear inside the hub , this is actually very good , the main issue with it is it was always put on already too heavy bikes like Grifter, chopper and bomber , on an aluminium bike this gearing would be great
I rode a bike that changed gears by merely coasting and backpedaling a tad (not enough to set off the brake). Any idea what they're called? Are they still made?
The original machine had a base-plate of prefabulated amulite, surmounted by a malleable logarithmic casing in such a way that the two spurving bearings were in a direct line with the pentametric fan, the latter consisted simply of six hydrocoptic marzelvanes, so fitted to the ambifacient lunar vaneshaft that side fumbling was effectively prevented. The main winding was of the normal lotus-o-delta type placed in panendermic semi-boloid slots in the stator, every seventh conductor being connected by a nonreversible trem'e pipe to the differential girdlespring on the 'up' end of the grammeters.
That fancy voice didn't explain the sudden neutral between gears that seems to know when you are peddling while standing up. How do they do it, witchcraft?
Did that more then once lmao....one time I managed to fall over the handle bars going pretty fast when it suddenly hit neutral while giving it standing lol...that time learned me not to trust it no matter what.
Basically there's a gap between the clutch engagement points for 2nd and 3rd - this is because engagement of both gears at once could destroy the hub. (Or so I seem to remember) Careful cable adjustment can prevent it in most cases - I've over 2500 miles on my NOS AW and it has not required a cable adjustment since the first week, neither has it given me a false neutral :)
@@axwomble8776 you got it in one. The hubs rarely go wrong, it's bad cable adjustment and sticking cables that let the clutch get stuck between the gear ring splines and planet pins (AW and SW series three speed hubs) or planet cage dogs, giving the no drive.

Faster speed, slower rate ... this guy needs to learn his derivatives. Fast and slow are already qualifiers of speed, as are speed and rate. Combining them forms accelerations.
It *would* take Sturmey-Archer to take the pin/roller analogy and absolutely bollocks it up: The "roller" (planetary gear and pin) should NEVER have been moved to the left of the screen when the "floor" was added. Visually, this makes the point appear as if it traveled the exact same distance as before (as it winds up in the same spot on the TV screen as in the previous example), even though it did move further. Problem is, most minds will fixate on the center of the planetary gear as a reference point - not the floor, which becomes a *new* reference point in the second example. The planet cage rotation is also over-complicated in its explanation. The planet cage turns 120 degrees to the pinion's 90 degrees. Done, end of story. It didn't require the narrator to repeat the same concept backwards to the same animation. Don't get me started on the gearing bit that follows, which is *way* too rushed. You could dub the Turbo Encabulator script over this and it'd make as much sense. It's as if the same person who wrote the Dynohub GH6 service manual was involved in making the animations for this video. It's a good thing they didn't try to sell the AW with this video, or nobody would have understood or bought the thing.
the principle is pretty simple , but this video makes it look so over complicated .. bad way to explain , and over complicated drwings and colors everywere
the sturmey archer hub is pretty cool piece of engineering! but come on... u are watching this video using a machine that draws the data instantaneously from half way around the world at the touch of a button, this stuff didnt happen in 1902 so i think there are still plenty of genious engineers and futurists out there, dont worry!
Sturmey Archer hubs are now made by Sunlite or Sunrace.. I'm not exactly sure. I'm also not sure of what country they're made in either, it's somewhere like China or Taiwan but definitely the margin for error isn't what it used to be in the 70's. I'm still a fan of these hubs and I'm very glad they are making the 3-speed fixed hubs again.
The quality is even better. They use new machines and tools. I used made in Taiwan SA XRF-8 in the mountains. Far outside normal torgue limit. No problems at all. Try this with new Shimano hubs. And you can disassembly avery SA hub w/o problem and replace the weared out parts.
@@vladimirstartsev2421 They use the same machines that were on Triumph road. When they bought the rights, they bought all the drawings and process machinery. Currently they're making the version that was first used in 1958.
Not true! Read The Sturmy Archer story by T. Harland. The true inventor designer was a man called William Reilly--- messrs. Sturmy and Archer cheated him out of his design and went on to be wealthy and famous. Reilly died in poverty in England in the '50s. Shame on them!
