You converted a safe bike into an unsafe bike. The frame and fork pipes you soldered your caliper supports on, were NOT designed to handle the force the disc calipers will put on them ! It's pure physics. The braking torque applied on the wheel (when you brake) is about the same (disc brakes don't stop the bike faster than new & well tuned rim brakes). Torque = Force x (distance from the center of the wheel). But the disc brake pads apply the force WAY closer to the center of the wheel (on the small diameter disc), than rim brakes (on the big diameter rim). So at the same torque, the force applied by a disc brake pad on the frame, must be WAY higher than the force applied by a rim brake on the frame. Also multiply that big force by two, because a disc brake applies the force only on one side of the frame (a rim brake has brake pads on both sides of the wheel, so the braking force will be applied on both frame bars on both sides of the wheel). The same thing for the front brake. A fork failing while hard braking is really dangerous. My advice: If you can, revert quickly to rim brakes. If you can't, cut that bike in pieces, and throw it in garbage. Don't let your kid ride it. It's dangerous. I like how you sing, and how you love your kid, that's why I spent my time to write all this.
@@jamesellis5549 it's not the welds that are not safe my dude. It's that the bike itself was never designed for the disks in the first place, like the fork legs themselves. What happens when a modification like this is done is that inevitably the fork will bend of break (same with the rear), and more than likely fuck up the user. It's totally possible it will be fine, but I wouldnt risk my life just because someone told me disks are somehow better on a bike like this than v brakes.
Carlin Anderson - I’m thinking about the leverage points and I think the three points to consider are: tire to ground, hub center, v-brake mounting point or fork/frame point. Seems that the forces will end up being distributed close to the same. With the kids weight and braking power, no problem.
@@chucknoob7041 you must be American. Only Americans think they are smart, when they have ABSOLUTELY no idea what they are talking about. Like Trump farting ideas about how to cure covid-19. Mankind laughs at you man. Those points you mention don't matter at all. The only thing who matters is the force applied on the fork (at front) and frame (at rear) at the caliper attachment points. I think your brain will finally start getting it, when you will see the following fork failure, caused by disc brakes installed on a fork not designed to survive the high forces disc brakes put on it - to get the same braking torque performance the old v-brakes were getting anyway ... since ages ago. This is the link: cozybeehive.blogspot.com/2010/10/braking-induced-fork-failure.html
I'm a retired aerospace stress analyst that analyzed every type of welded tube structure on aircraft. I also am a licenced faa certified airframe mechanic. Just by observation of this welded bracket conversion, I'd say it is a well done installation and the loads that are going into the brackets by the calipers during stops are directly into the centerline if the tubing with no offset bending moments. Therefore the backup structural tubes are more than adequate to react any braking loads over the 4" of distributed bracket loads. Since the rear brakes react about 30/49% of the entire required braking force, the bending load into the rear down tube at the rear bracket attach location would be less than 200 pounds by rough calculation distributed over the 4" bracket. Steel bike frames are typically made from chrome moly steel which have about 125 ksi FTU and about 100 ksi outside of the HAZ of a weld when annealed. The Fty an = about 60 ksi. The bending moment from worse case 300 lb at this location in the tube with fixed ends would be PL/12 = 300x 15"/12 = 375 in-lb. Stress = mc/I, where I for 1/2" tube with .050 wall = about 0.002 in to the forth. So stress= 375 x .25 / I.002 = 46,875 psi. Factor of safety = 60/47-1 = +0.28. yield. This conversion is good. The front forks have almost twice the bending inertia with 3 times the load of the rear bracket. Therefore good by inspection. This is your Lockheed style stress calculation factor of safety. So please don't say this is an unsafe conversion. If u do, plz show your calculations that prove other wise.
Great trusted calculation sir👍have done this to my old steel roadbike too, everything work good. And i still dont find any problem in my fork. (1 years used)
@@fendipakeen7295 Only thing you might want to consider is when you arc weld two pieces of steel together like you did with the bracket and the bike frame and the front fork, is to heat that weld area with a touch to about 800 degrees (dark orange glow) and let it air cool. The arc welding (at the weld and slightly outside of the weld ) has hydrogen embrittlement and is prone to cracking When the weld area is heated, it relieves this brittle area and makes the metal softer in that area less likely to crack at or near the weld. It's called metal annealing. It is much safer to gas weld steel tubing and brackets to it because the method incorporates annealing just from the heat of the weld.
@@ginginthing Hello, if I might ask you a question. I'm considering learning to weld in order to start building steel frames for bicycles. I'm at the first stages where I'm doing research and found that vintage steel frames were welded together with brazing and flux. I searched around and found that it's a very messy process, and liked the cleaner aspect of TIG welding. So my question is, in your opinion, and as a professional who understands this kind of thing, which is the best method to ensure my frames will have the best quality welds? TIG, Brazing, or another one I haven't mentioned? Thank you in advance.
What I love about this post is the practical simplicity of it! Here I am, seeking to rent time on a cnc machine, making out measurements on a computer and considering buying engineering tools, all because *I love my bike* and I thought the switching to disc brake requirements was totally both unfair and unnecessary to a *loyal and dear old friend/my bike* ! Willing to spend $3000 on my ❤ than $1000 for a new one! 😀
As someone who is qualified welder to 6gr standards im well aware 1 inch of weld will support 1 ton in weight if for one its good quality weld and not a load of snot and spatter clinging to a bicycle front fork tube no more than probably 2mm thick not designed to put up with braking forces, accident waiting to happen this pos bicycle
Absolutely the best bicycle disc brake conversion video hands down .... Great job ! Ill be using the same exact technology for my motorized mountain bike ... Thanks
You should keep in mind though that a rim brake frame isnt designed for the forces disc brakes put through it. Especially on a motororized mtb the brake forces are pretty high. You might bend your seatstay and/or fork leg.
@@dermomo3868 The bending seatstay issue could be avoided by welding an extra support between the seatstay and chainstay. The metal he welded to the frame also seems too thin to fully withstand the stress from braking.
Cool - I need to put a front brake on a 1970's cruiser conversion to ebike and it only had 1 brake, this solves my problem. Nice production loved the chickens and the song at end.
Haha! That's they way I've done my STEEL FRAME brake conversions! I used to use them eyelets and screwed them on the rear triangle. Works awesome too! 🤙🤙 Can't beat the $29.99 brake kit. I love them components. They are just as good as shimano..😊
Just by observing at the welded part , i barely consider the finishing quite impressive.. this man has proof he is competent n has completed his tasks very well... My thought maybe he was somekind like welder or foreman who experienced working offshore longtime ago...
I'm an Italian to English interpreter and I can tell you that those welds are OK, if they do happen to break during use the solution is easy, just weld them again.
super cool convert! I just have a question about the welding part, i dont know anythig about building bikes or welding, but could the heat from the welding affect other parts of the frame? , if it could affect the frame, is it possible to prevent it with like covering the frame with some wet ice cold towel or something?
Thank you for posting. I enjoyed watching this. With some adjustment to the welder, and some practice, you could go a little slower and get deeper penetration... making the bond stronger. I appreciate the time and effort to record and edit the video.
there are disc brake caliper that go onto the tube of the frame, a gravel bike my coworker has this, no extra hanger needed, you just need to drill and tap holes for them
For those that say use a mig welder, maybe he hasn't got one, he could buy one but if he wanted to spend money he'd probably buy a new bike with disk brakes already fitted. He did a great job with what he had.
Me encanto ver el procedimiento del trabajo, y me gusto ver otra idea para mi bici por lo del cambio de velocidades ya que lo tengo con la rueda y no como la tuya, voy a ver si puedo hacerlo
Ahhhh the comment section where all the welders hang out and comment about something but fail to post videos of how to do it right? Come on guys get your videos out and show us how to do it properly? My frame NEEDS disc as my new wheels are disc only. I would use mig because i have some experience with thin welds . Arc is too ticklish for me to try. I like how he decided to make his own parts and shows how.
Nice work I see quick and easy no messing around , same way I would do it , although I would add a brace in the rear triangle and maybe something more for the fork if I feel it needed it.
For the rear brake, i believe it is pretty safe to do so, the brake force is so much weaker than on the front one -- the harder the brake the more weight thus more tyre grip shift to front wheel. I would not play with the front brake though.

With stick welding and metal so thin as 1mm and less, there is constant battle betwin keeping arc alive and not burning hole in bike frame.
This is super cool, next time turn the amps down on your welder and go slower, you'll end up with a stronger and cleaner weld
Thanks for the tip
