This is the best frame-building video, period! I learned many things from it. I'm very, very picky when I rarely subscribe to channels but you definitely deserve a place on my shortlist.
🇬🇧That, James is a work of Art!💯 I'm very proud to be Subscribed! I used to be a fabricator in a welding shop and watching all you do brings back nice memories!👍. 🤘😎🤘
living my dreams through your videos, (I dream one day I would be able to turn metal into something beautiful like you do.) absolutely stunning work, and the ability to bring imagination to life.
Well, this dude got some real talent under his sleeves, got plans for his previous build, can't wait to see the plans for this one too. one man army. Hat's off to you man.
Subscribed and I can't wait for the follow up on this video. I am working on the design of a trellis chassis for a 1972 Harley Davidson Sprint 350cc engine. I was working on the frame jog but I saw and downloaded yours. That will save me time. I am going to use 3/4" and 5/8" 4130 tubing not including the steering head. Most of these bikes use a huge backbone tube and castings where the swing arm mounts. I am working on very light weight. Single rear shock mounted above the engine and the muffler will sit next to it above the engine. The goal is light weight and as much mass centralization as possible. Many years ago Matisse made a trellis frame for it but they are long gone. I am retired now and am using AutoDesk Inventor to do the design. I have an engine sitting in the garage and am looking forward to the project to get started.
I learned lots of new tricks here. A tool you could build & use - simple as exhaust clamp. Clamp to round tubing to get a flat reference before using tube bender. Really handy for lining up multiple bends on single piece. I made a square with a hole (size of tube) then cut in half. Added two counter bored holes on one half & tapped hole on other. Easy to clamp to tube with socket head bolts.
Just randomly came across your channel - great work - now subbed and getting psyched about a binge watch of episodes later!! Keep it real and accessuble! ❤😊👍
Brilliant! I’ve grown to really enjoy your work on your channel! I feel like there really isn’t a limit to what you can do! Have you thought of your next project yet? It would be interesting to see you attempt something like the Jetson One. Where you build the cage and custom batteries to fit and then order in some controllers and bldc motors. I mean flight has to be your next direction Id assume at this point! Thanks again!
Wow, impressive. It would be nice to see the same quality put into a mid drive electric motorcycle! I know its probably a bit more work with the gearing, chain, tensioning, etc but probably worth it and you get tuning of the gearing, better rear suspension, less weight, and probably more reliability in return
Love the frame build! The only thing I would change is to make the dropout for the rear wheel a bit stronger. I have mountainbikes which have beefier ones . They take a real beating. Just wouldn't want to see you get hurt.
Thanks. They'll be fine though. I've done this quite a few times already, and they're far more robust than the small aluminum dropouts on any dirt bike I've ridden - they take far more beating than a mtb. 3/16" steel is pretty tough.
You can get an app on your phone that does angles and bubble level. The sensors in phones are as good or better than what's in the tools. Mine is dead on.
I'm already looking forward to the next video, because the frame has become really nice!! There is also a lot of work involved, which is not always evident in a video. Really great work. ;- )
Thanks for sharing your knowledge,I don't have any experience with fabrication or welding but want to start a project with my 15 year old son...and daughter if she is interested.Does anyone have any recommendations for courses or tutorials on tube bending? What type of welding should be learned first? Mig or TIg? Ty
Do you have a trick for eyeballing measurements between tubing. Just ball park the angle of your eye in front to 90 each time? This comes up in wood working sometimes I find too.
I lime your pipebender, can it be possible if i can ask some of the process of of making one?, im from the philippines and i admire your r work ciz i love building bike chassis
well done. I'm just wondering why don't you make removable (bolt on) subframe so that in the event of crash if it gets bent you can easily make new one and replace it
I guess, if you want a super tight radius that pushes the limits, but I don't think anyone does unless they're a blacksmith because you'd have to bring it to its glass transition point first for it to make a difference, which would involve a forge. Steel flexes to a degree without damage naturally, and isn't affected by bending anywhere near as much as aluminum, for ex. That's not to say aluminum isn't good for stuff like this because it is. But if I were to place a plate of each in my sheet bender and bend them 90° around a 1/8" radius, the steel bend would look smooth and uniform whereas the aluminum would have noticeable micro-fractures along the length of the bend. But this doesn't happen with a 3" radius die like what I'm using to bend the tubing.
beautiful work and looks like you shaved off a bit more than 20lbs. wow, so many questions like how long does it take to create expert aluminum welds? what are your suspension choices are going to be (full ohlins maybe) , and is it a good idea to use regenerative brakes on something this light and would it impact ride characteristics? can't wait for your next one. thanks again!
Thanks. Haven't had a chance to learn how to weld aluminum yet - this frame is DOM steel. Suspension won't be anything fancy. Like all of my projects, this is a budget build, so I won't be spending thousands on an Ohlins suspension. Just a simple shock with progressive dampening linkage in the back and girder forks with a progressive coil-over in the front to mix some retro elements in with the modern powertrain tech and give it more of the cyberpunk/Mad Max look that I'm after. Regen braking should be used with any and every e-bike regardless of size, if available. Converting the motor to a gen and dumping power back into the battery causes a braking effect on the vehicle itself, without using the actual hydraulics. This lowers the wear and tear on the hydraulics, but too much regen current can cause abrupt/uncontrollable braking or damage to the battery. The amount of regen current that goes into the battery depends on the mass and speed of the vehicle, since the energy that the motor-turned-generator is producing is coming from the kinetic energy stored in the vehicle's mass when it's moving. Small bike + slow speed = low charge input, big bike + high speed = high charge. Charge current limits to protect against overcurrent issues with the batt can be set by the user in the ESC, in most cases, or set by the manufacturer if the ESC isn't user programmable. Custom builds usually involve programmable ESCs, and like all of the performance settings, the regen braking current limit - ie: the amount of current and braking the function provides - is adjusted after test rides to suit the user's preference and batt specs.
@@JamesBiggar thank you so much for the mechanical consideration fundamentals, don't know anything about e-bikes but watching your build videos is just so inspiring, apologies for missing the tubing material not sure why I assumed it was aluminum. the fact that someone can build such an awesome machine on a budget (if one had the skills of course) is even more inspiring.
That frame is beautiful. Awesome job man
Thanks!
That's a beautiful chassis design you've made, and I'm jealous of that chassis jig as well! 👍
Thank you for sharing processes that few of us get to observe! As usual, beautiful design and execution.
This is the best frame-building video, period! I learned many things from it. I'm very, very picky when I rarely subscribe to channels but you definitely deserve a place on my shortlist.
I really enjoyed the first bike build. Watched it many times over and over. I can already tell this build will be no different.

🐐🐐🐐🐐🐐 you are the man this frame build is sick! Excellent work my guy!!
👌 *nice frame.. ditunggu kelanjutanya*
That jig is cool!
Glad I discovered your channel!! Can't wait for your build to progress! Good luck! Thank you
Thanks and welcome!
YES! I'm so excited when I see new project from James! 😁😁
I'm really looking forward to the next episode.
With these inspirations I'm starting to develop my electric motorcycle, here in Brazil
You make it sound so technical.
Me, I'd be like...put this thing in this. That didn't work. So I did this and got mad for awhile and quit. 😆
You are a master man, well done.
Simple and avesome explanation. Thank you dude.
Another great build James. I like the narration. It reminds me of a Harris Magnum frame from the UK.
impressive fabrication skills,brother!
Sei un capo..!! Complimenti.
I just followed a guy that's made a ebike version. ORTONS CUSTOMS. You guys are different cool guys😊
Beautiful frame.
The precision work 😍😍😍😍
I'd love to see this a little longer, FAT tires, as a Cruiser. Great work!
HELLO I WISH YOU GOOD LUCK ✋👍👍👍🇰🇬🇰🇬🇰🇬
I AM FROM KYRGYZSTAN
One of the best.So ımpressive result. My best regards👍👍👍
10:10 16:02 No, no, no, no, no.. You can't mix grams and pounds!!! 😂 This thing looks fantastic! Amazing work. Thank for sharing!
awesome job man.. I like that frame design. congrats man
The two year wait was worth it and the body looks proper, can't wait for mk II's next installment
it's like as if we could watch davinci narrate and film his inventions creation process. thank you!
funny, me as an artist thought about the first bike-welders more than 100 years ago and how excited they maybe felt ...
well done.. great skills...
gonna wait for the next video.
the contraption really helps a lot.
You are awesome dedicated man.. I wish I was with you and learn..
Best of luck for your project.
excellent work, thanks for sharing
You got a perfect process 🔥
This was an awesome video to watch. I look forward to the rest to come.
Good clean build so far!
Ты просто красава!!!
Твои изделия это что-то

Master craftsman 👍
I wish LOL
I really admire your work with the tools that you have. I have a lot of professional tools yet I can’t make a average bbq set…😅
I like the design you chose. Looks very clean and badass at the same time. Hopefully one day ill be able to do a project like this
Great project!
wow, that's a thing of beauty!

Nice jobe, man!!!❤❤❤
Look forward to seeing the results this reminds me of the Duke monster
As a fellow frame builder,, love it, fabwork done right,,, just wished youd have tig welded it
Eagerly waiting for second episode
hearing your smooth welder gave me the rest: I HAVE to service my MIG-Welder!!
Hi James, good to see you working again: btw awesome frame, light and the geometry is just cool.
Fantastic work. Was a pleasure to watch.
You can get an app on your phone that does angles and bubble level. The sensors in phones are as good or better than what's in the tools. Mine is dead on.
U doing very will.
We love u.
amazing skills !
very nice frame
nice! good thinking to copy known geometry; so many people slap stuff together and it handles super sketchy.
Just two worbs : you rocks !
words, sorry
너무 멋진영상 잘봤습니다
Прекрасная работа!

Been a joy to watch your skills grow James! Well done with this, it looks amazing so far!
Thanks!
Nice vid, did you build that bender? That thing is awesome.
Thanks. Nope. I got that from Kaka Industrial: www.kakaindustrial.ca/products/kaka-tb-3-hand-pipe-bender-manual-pipe-bender
Primero saludos desde republica dominicana
looks incredible! following!
Thanks!
Verry good idia sir
that is impressive to see how much can be done with different design. losing the 20 lbs is significant.
12:20 welding really went...*chidori*
thanx for this awesum vid
Do you have a trick for eyeballing measurements between tubing. Just ball park the angle of your eye in front to 90 each time? This comes up in wood working sometimes I find too.
Pretty to watch! Can I ask how much the project will cost roughly once complete?
i love bike,best of luck
I lime your pipebender, can it be possible if i can ask some of the process of of making one?, im from the philippines and i admire your r work ciz i love building bike chassis
Biggar and better!
Really nice work. That frame building jig is great. Have you got a vid on how you did that?
Thanks! Yep, check the video description for a link.
@@JamesBiggar Cheers. Found it now.
are these plans available anywhere? incredible work!!
Thanks! Not yet.
Good job
Posees un talento enorme.
well done. I'm just wondering why don't you make removable (bolt on) subframe so that in the event of crash if it gets bent you can easily make new one and replace it
Lol, I did. Look closer :)
@@JamesBiggar my bad
Would it help to heat up the tubing a little bit before you bend it? Reduce stress fractures? 🤔
