1. Great video! I appreciated the stories. Felt like a conversation I would have with a guy who has years of bike experience.
2. Wow! This really took me back to the 1950's as a kid. Fix them or walk Would like to see a video about the type of coaster brake with all the little flat discs that were like a miniature disc brakes. Had a bike once like that and the brakes worked well but, sometimes the pedals would not engage to go forward. My dad or I was never was able to fix this problem. Years later, I was able to find the cure.
3. What stops that cone from spinning with the hub when you use the brakes but then allows it to move with the hub when your petaling the bike forward
4. I still have a bike with exactly that function. Right now I'm trying to fix mine because one of my bearing at 8:09 broke after I was riding and my rear wheel jammed up somewhere in there and I completely lost all the silver little balls on the bearing, and I have to replace it. Anyways, when I opened mine there was a bunch of black grease and I don't know if I'm going to clean it or not or if it's even important or not. This video really helped with my understanding of these Coaster Brake, But I'm still unsure of what possibly happened to mine and what the bearing at 8:09 has an impact on it. Reply? :)
5. I always wondered how it worked
6. This is great. My interest was piqued in coaster breakdom very recently by a visit to an Endodontist. The office is in the old (>100 YO) New Departure administrative building in Bristol CT where Harry Townsend patented a coaster brake in 1898. There are old pictures and advertisements on the walls in the entry way. I have always wondered how the brakes worked having used them as a kid. BTW, there are parks named for Page and Rockwell in Bristol. Its quite sad that New Departure is completely gone now. GM shut the most modern Bristol facility in the 90's. Much of the old buildings still stand and is a reminder of the once great manufacturing core in the USA.
7. Great video, you're so good at explaining things, thank you
8. Fascinating! I love all your videos. Now, I used to have a two-speed with a Bendix brake. My most favorite bike ever. How the heck did that work?
9. Brilliant video, thanks a lot for sharing your time and your knowledge.
   I was trying to fix a bike with a shimano nexus 3 speeds internal-gear hub today and didn t even know what the metal rod attached to the frame was, till a friend of mine explained it to me.
   
   Now I wish I could get how those internal gear hubs work, watched a video but it is still beyond my understanding.......
   
   Keep up the good work and greetings from Austria.
10. thank u sar
11. a shortened and animated version would be one of youtubes best
12. I remember having about a dozen free bicycles as a 10 year old just to keep replacing all the parts that failed. Had to replace one of these once, but they just drive and coast, the braking was done through handlebar brakes. My dad used to say "The garage here looks like a mexican car dealership" from all the bicycles lying around.
13. Thanks, This brings back memories as this was the first mechanism I took apart. Having a paper route in grade school you needed a bike to shorten delivery time.
    
    I remember taking the back hub apart in 7th or 8th grade because the brake would not work. Ultimately the brake shoes were worn. It took me a number of trials to take it apart and diagnose what was the root cause of failure. It was a dirty job and the first thing you did was fill an old coffee can with some gas and wash all the dirty grease from the parts. It was a small yet significant accomplishment fixing your own bike. Perhaps the reason I chose engineering as a profession.
    
    Keep the vids coming! Great Work.
14. If you remove the hub and reassemble the rest of the mechanism, hold the brake pads in place and snap a rubber band around them. I think you will be surprised again at the beauty of it all. Myself and a few friends once took one apart and couldn't make a cut away, breaking every saw we used to cut the hub, and the hub wasn't even nicked as I recall. So I came up with the rubber band approach, and my goodness we analyzed that thing for hours, watching the brake pads expand out. Seeing how the system moved from drive to brake and learning the quirks of the design. We did this because we were convinced if a bicycle hub could be used for breaking it could also be used to power the bicycle from a motor or generate electricity from inside the hub. We never figured out how to do it lacking the tools to even cut the hub, we clearly didn't stand a chance probably. Now a days bicycle hubs are made with both motors and generators inside the hub... Would have been nice to invent that technology. I think we also took one of those Sears 3 speed internal hubs apart, those are even more amazing inside! Good stuff! 🚴🏻
15. i took one apart when I was 8 and got it back together and working
16. ........Pepperidge farm remebers
17. Wow, I remember those. Me and my brother used to collect every junk bike we could find and strip them for parts. we had a garage full of bike parts.
    
    If a bunch of friends showed up to go ride and one didn't have a bike we would just build him one on the spot.
    
    Only things we ever spent any allowance money on was the occasional can of spray paint and some matching hand grips to make one of our creations a little bit pretty.
18. My bike had a oil cup in the center of the drum (I used 3in1 oil) and a clutch pack (alternating steel plates and clutch plates with splines in and out as the breaking element.
    I believe it was a Schwinn. My pop bought it on credit from "Western Auto" over 66 years ago.
19. You are a great teacher, I am very intrigued. I sure did wear out a lot of tires when I was a kid, my Mom would yell at me when I would leave a 10' skid mark on our sidewalk. Now I'm in my 40's and this brought back some memories, and answered my questions from many years ago about how these worked.
