« on: January 11, 2010, 09:46:17 AM »
How does this hub work?  Is it like a kickback?  Why is it called automatic?

Don, there are three varities of the "automatic" hub. Reading the T R Findley pages will give you quite a bit of information. I grew up using a what was more than likely the "yellowband" 2 speed. When I tell people about how my childhood bike worked they give me strange looks and most have never heard of it. The "yellowband" was made until around '68-'69. Mine and my brother's were more than likely 1966-67. I wanted to find a frame and build a 2 speed like we had when we were kids but they would be way too small for me now. I'm thinking when I get done with my current project I may find a later 70's 24" Speedster frame and put a "yellowband" two speed together around it.

Jennifer,  I have never rode one of these but...  I plan to.  I was looking at that red band one on E-bay but it is not correct for the year bike I have in mind.  I need a yellow band to be correct.  I have a bike that I have bought but is not here yet. It is a 68. 
Thanks to Bob I did not bid on the wrong thing!

I'm thinking when I get done with my current project I may find a later 70's 24" Speedster frame and put a "yellowband" two speed together around it. 

I did this a number of years ago except I wanted something a bit lighter so instead of using a heavy Schwinn electroforged frame I used a Japanese lugged chrome moly frame and 27" alloy wheels. I made it a "city" bike with upright tourist bars, a rear Pletscher rack, and a cushy saddle. I also incorporated caliper brakes as I wanted more than just the coaster brake in the yellow band hub. It was my commuter bike for an entire riding season, but the next year I moved on to a bike with more gears.

I thought about that option too Eric. It's all just an idea for me right now. I did read all about the 2 speeds when I found the information and it proved I wasn't imagining things. As it turns out Schwinn wasn't the ony company to use the Bendix 2 speed Automatic nor was Bendix the only company to manufacture them. Sachs and Fitchel made a 2 speed automatics. The Duomatic was a "kickback" style and the Automatic was a truly "automatic" hub. It shifted because it wanted to and not neccessarily when you wanted it to.

Echo_Delta , I have been ridding with Auto two speeds for years and love them. They are tough and easy to disasemble and grease. Red band came out in about 1960 and went to about 1964. Blue band was tipicaly used on 20" through the mid 60s. Yellow band came out in about 1965 and went to around 1970 and could be found on most size wheels. I just finished lacing a yellow band into this 1972 Typhoon this last summer, It made a big difference , It was a single speed.  Jeff

Jeff, I bought a bike that I would like a automatic 2 speed in it.  It actually might have one already...  I bought a bike in Phoenix on December 4th; I had a customer that was going to Phoenix for Christmas with a big race trailer.  He was going to bring it to me at a race in Florida in late Feb.  His trip got postponed.  The bike had an option to go single speed or automatic 2 speed.  I frankly did not know what an automatic was or how it worked.  I had heard of a kickback and I am bright enough to figure that out.  I did not know they were the same.  That is the reason for my original question.  I did not ask the guy in Phoenix because I do not want him to get "Sellers Remorse." My customer might be going next week.  On the outside my wife and I will go in the middle of March.

The second favorite thing for me behind a schwinn is a bendix, especially the two speed.  They work great and I love both of mine.

yes they are great! the red band and yellow band are the same except the red band has brake discs instead of shoes, and the gearing is fixed speed, kickback,lower,and the blueband was lower gear ratio, kickback, overdrive, that's what made them popular with 36 tooth stingrays, low gears for wheelies, kickback, ahhhh overdrive! :)

There is no "kickback". To shift just back pedal and it shifts, every time. Slamming on the brakes to shift does not shift
faster. The back pedal motion cause the index spring to move and when you pedal forward it shifts, Automatic like it says
on the brake arm. It does not say kickback.

It's called an automatic because originally you'd take off in low gear, kick the pedals backwards (hence the kick-back) to shift into high or Normal gear (assuming you had a hub that wasn't the blue one) and when you wanted to stop you'd back pedal, applying the brakes and shifting it back into low, making it automatically in low ready for you to go again. The only time this doesn't really work is when you are already in low and want to stop, you have to back pedal twice to be in low again upon a stop.

That's what I would call a true automatic hub.  :o... 8)    I wonder if it would be a plus or a negative though. Shifting when you don't want it to shift or not shifting when you want it to. Kinda like the stupid 1 to 4 in the Corvettes. You maintain a certain rpm in first gear and then you try to shift into second and you grind your gears like Grandma trying to throw it in reverse while still going forward. I would really be interested in reading some consumers comments on that hub.
