Check out my new electric buggy that I just finished building: ukposts.info/have/v-deo/sHKdZ4F_r3mqsn0.html Here are some answers to your most common questions about the bike: #1 - "Why did you block the welding arc?" - Because flashing bright lights can trigger ocular migraines in people like myself which literally blind us temporarily, and can cause seizures for others. I can only weld for short periods at a time because of it. It has absolutely nothing to do with UV light or flash burn (which can not happen through a video). #2 - "What's the top speed, acceleration time?" - I didn't fool around figuring these out on the road for what should be obvious legal, safety and liability reasons. These are better tested on a track, which I have no intention on renting because I personally don't care what the bike's limits are - I don't race professionally and I certainly won't be doing it on the street. But we can use well established math and science to figure it out for those of you who might be interested in building or converting a race machine to electric. Check out the video description for theoretical top speed and acceleration specs. You're more than welcome to build and test for yourself. #3 - "What's the cost to build?" - See the video description. I broke down the cost and created a cost benefit analysis based on gas prices. Bare in mind the calculations were done prior to fuel prices doubling recently, so the savings to be had will be substantially more than what I've shown. #4 - "Why steel? It's heavy!" - for the same reason most street bike frames are made of steel, because it's affordable and not too heavy. This frame (including swingarm) weighs 30lb. You can verify using the BOM and links below. For comparison, a typical aluminum sport bike frame weighs 26-28lb. The lightest motorcycle frames are in dirt bikes, weighing anywhere from 17-25lb. Street and sport bikes are the next heaviest at 25-30 lb, and cruiser frames can weigh between 50-80lb. Aluminum or carbon fiber would shave 5-10 pounds from it's total weight of 300 lb. Do the math - at 80 km/h that might translate to saving 30-40 watt hours of energy per charge. At 100 km range per charge from the 4 kWh battery with the current weight, dropping 5-10 lb to save 40 Wh might translate to adding an extra 1-2 km per charge. The end doesn't justify the means. Steel tube chassis' are far more affordable for one-off custom build and a lot easier for the avg bike builder to make - that's why 99% of street bikes still have steel tube chassis': www.electromotive.eu/?page_id=12&lang=en #5 - "Can a completely custom motorcycle be licensed?" - YES. Any custom personal vehicle can be licensed and insured for public road use as long as it meets safety and equipment standards for use in your state/province/country. Some folks seem to think it's impossible unless you're a manufacturer, but that couldn't be further from the truth. Here's a breakdown of how it works in my humble little province of New Brunswick: Step 1: Know what you're doing. Building a custom vehicle is not a project for the avg DIY'er. You're going to need to acquire some skills and knowledge in automotive design and fabrication before jumping into something like this. I don't mean an engineering degree, but you'll need to at least spend a fair amount of time training with someone competent in automotive work. Like an apprenticeship. If you're not following a set of plans, then you'll need to dive deeper into things like chassis design and suspension geometry - it matters, a lot. Step 2: Check with a local engineering consultant about the regulations and requirements for custom personal vehicles to be licensed in your area. Again, you can license your own ride, as long as it meets the requirements, which will differ with region. It would be wise to talk to your insurance company at this point, too. Step 3: Build and test your ride. You'll need to play guinea pig. Take it for a ride in a parking lot. Check the brakes first, then performance, tune the suspension, etc. If you can, book a track for a day. Step 4: When you're confident that you've done a good job, book an appt with a local engineer to have your ride inspected and tested on a brake and power dyno. If it passes, they'll certify it safe to be driven on public roads. Step 5: Take said certification to the DMV to apply for a VIN# and acquire a license/registration. You'll need to prove that the vehicle is yours, so keep EVERY receipt for every part, nut and bolt that you buy and install. If you can't prove it belongs to you, then you won't get a title for it. Step 6: Purchase insurance. Step 7: enjoy your ride. With this bike, you will save a significant amount of $ in the build compared to buying, but it WILL cost you more for the initial inspection (you only need an engineer to inspect it once), licensing and probably insurance too. So do your homework before jumping into it. But for most builders, the satisfaction of driving your own creation is well worth the $ spent. NO - crash testing is not a requirement for custom personal vehicles OR mass produced commercial vehicles anywhere in the developed world, contrary to popular belief. Manufacturers conduct crash test solely to further innovation and win safety awards that serve as bragging rights when marketing their products.

This guy brought a whole new meaning to “fine, I’ll do it myself”

When someone makes an entire motorcycle from scratch and makes it look easy, you know you're watching a master at work. Amazing build!

I have all of the “raw” skills this guy has… I can weld, shape, electric…. And I am convinced it would take me 5 years to fabricate all these parts. Superstar. Subbed.

Dude… this is extremely impressive with minimal equipment like yours! On a personal level it’s actually…… manageable!!

Just think guys, this is his first design. Just wait until he improves it even more. I wish him all the luck in the world and hope to see him develop and grow a company.

can we just appreciate that he shields our eyes when he welds

Did we just witness 1 person building an entire bike start to finish. Mind = Blown. Insane build skills. Brilliant!

I consider myself talented in many areas, but you sir are ridiculous! Insane talent and skill to not just accomplish this but also make it look easy! Well done!

He's like the evolved version of the guys who build houses in the jungle using mud and sticks.

The only change I'd love to do is changing the location of the electric bike from your garage to mine. Awesome work!!

This gives a whole new meaning for the phrase "Built not bought." Amazing work man.

There is no words for this, except WOW !! Not only for the technical skills but equally much for the great design. Well done.

I came here trying to learn about converting my bike. This guy builds it from the ground up. Beast.

Cops: You have registration? Him: I am registered.

What an inspirational (and aspirational) project James! Thanks for taking the effort to share and thoroughly documenting your build... it's now on my build list :)

One of the best videos I've seen on UKposts, most of the nodes were assembled from scratch, independently, beautifully and seriously. Thank you for this experience.

You're like a one man army. You did all the modelling, electrical, mechanical, etc.. You're like a real life tony stark for cryin out loud. Mad skills indeed!

No noise to disturb neighbor ✔️ Need speed ✔️ Light design ✔️ Sustainable ✔️ No pollution ✔️ Need copyright your own brand, do it. Brand it. Overall, 10/10. Further tweak: possible. I like it👍👍👍

Wow... that was something else! Every single part cut, welded, crafted and finished with masterful perfection... Awesome!

This guy can just step into his workshop and build a motorcycle. I can't imagine how awesome such skills are. It's incredible.

meanwhile some motovloggers make 10 episode series about cleaning the chain lmao

Hang on... that torque was limited to 16%, destroyed the road and nearly launched off the test pad in the garage? Sheesh! Man, this is a thing of perfection! Bravo sir, well done. You have my admiration. The design, attention to detail and engineering on display here is something to behold.

Deserves every one of those 16+mil views. Incredible build and quite the conversation starter, if you pulled up on this at my local bike stop you’d be there all week.

Thats just awesome! I built a little electric trike last year... very simple stuff.... but took me many months of blood sweat n tears....v. proud of it....but nothing like this... this is next level - genius stuff.....

This is the guy you'd want in your group in a zombie apocalypse

This is without any doubt the best build i have ever seen! I wouldn't hesitate to buy this bike!!! I'm blown away Great design!

The moment I saw you make your own bearing for the bike steerer/head tube I knew this video is gonna be a very interesting and rewarding one. ..Enjoyed every bit of it . ..

I watched this with my dad and now he is planning on build an e-rod with this. Thank you for sharing and inspiring.

Just did in his garage what took big manufacturers years to perfect ....And this is just a prototype... all the measurements and geometry.. Kudos to you Sir.. you are a true engineer !

Only thing that could have made the video better was putting the Cyberpunk 2077 music at the end, lol. Seriously, this video is probably my favorite on UKposts. The amount of skill and knowledge and engineering that went into this is insane. I'm blown away.

Thank you for this video. I think it inspires a lot of people by now, many people will definitely choose e-motorcycles now since it does not consume petrol. A very timely innovation indeed . ❤️

thank you for covering the arc, that's super bright on my monitor, and actually is annoying af, so thanks :) What you did here was amazing, it's almost convinced me to try a design I've had in mind for quite awhile. Material and time is the biggest problem. I hope someday I can do what you've done here.

He built a full blown e-bike from scratch. How can someone unlike this. damn.

The most impressive thing about the build is that, he did it all by himself

I take off my hat and bow deeply to this enormous DIY talent! Such skills are rarely seen in metal construction. The best solution I found was how to "grind" a ball bearing mount into the head tube with a clamped cut-off grinder... Really clever!

I've only seen 2 of your video's, bit I already gotta admit you must be the best fabricator on here.. Wish i had a tenth of your skills. Absolute madness

_“Tony Stark was able to build this in a cave...with a box of scraps!”_ This man took it seriously!

I was so impressed with his hard work and didn’t know where to start, I started doing push-ups 😂

Thought it was going to launch itself when you were testing it and the back tire contacted the floor! Great build, awesome talent!

Man,,,,You The Boss ! What you built at a *Home Workshop* Is Still Uachieveable For Our Manufacturers, With Pockets Bigger Than A Few Countries Entire Economy.

This dude must be proud of himself what a legend

Almost 5000 oil CEOs and investors dislike this video. 😂 Truly amazing work! I like how your bike looks. Compared to the commercially available ones yours looks really dope!

Not only home built but doesn’t even have the basic machinery - amazing. Vaseline for mold release - amazing

Boy!🥶that's the coolest thing I saw someone build with their own hands. 🥶🙌🏻

The father any kid from the world would like to have. Ironman.

How can anyone dislike this video?! This man built an emotorcycle FROM THE GROUND UP!!!!! Not too many people in the world can do that!

There's no two ways about it, this guy's just hella impressive... 💯💯

That freehand fabrication, wow! This is master class level. Amazing work man!

You live in your own world man. No talking, no neighbours, just making home made motorbike and enjoying it.

Absolutely inspiring. I've got a "custom" streetfighter in my living room that I've fabricated several of my own parts, but I've been itching to build my own frame. It's got to feel incredibly rewarding when people ask 'where'd you get that bike?' and you get to say I made it. Awesome work man and the bike looks bad ass.

Your build rocks, thank for the idea on how to make a rigid swing arm. 😎 Building one for my electric scooter conversion as well.

Mad demonstration of skills. Much respect to you on a great build.

"This quarantine was not boring to me" he said

I just sat in silence for 30 mins, this man is seriously talented I would buy one of these

My man lives in some cabin at an offbeat location and chose to build a bike straight outta Cyberpunk. Humans are impressive! ❤

That seat cover stapling part was so satisfying

Calling this “mind blowing” is an understatement. I rank you top 5 of all times on UKposts without a second thought.

This is where it all started “beginning of cyberpunk 2077”

Bro this is literally the coolest thing I’ve seen all year. Great build all together and great video editing also!

amazing work man,and very nice futuristic look,i already wanna have one,electric vehicule like this is very useful ,quite and you can avoid smoke ,oil and motors problems,love it 😍

You are the ultimate representation of many mom's saying: "We have this at home"

love how this is just mostly welding and cutting, no extremely expensive/fancy tools like a cnc machine or what have you, just technical skill with a welder and some patience. inspiring to say the least man. Good stuff.

The music at the end makes it sound like it's an action movie with the truck chasing the guy on the bike. Jokes aside, huge respect and great build

absolutely amazing. and 2 yrs ago! you are an artist. thanks.

And he's even protecting us (watchers/viewers) from the arclight. How thoughtful..

A team can't build such piece of engineering. You did it alone.

Amazing talent! Please use the multi vibrating tool next time you cut fiberglass, The vibrating head will not blow dust everywhere and the carbide blade cuts through the glass like butter. The maneuverability is amazing as well.

As cool as it looks, the thrill and the adrenaline from the throttling sound of a bike cannot be replaced.

This man's eyeballing techniques are crazy precise... is he even human?

Cooler looking than any e-bike I have ever seen in any dealership, and it was built by one man in his garage. Mind blowing 👌

This is pure art.. The design is flawless. I would love to see a scrambler & cruiser build in future 😎 Keep up the Great work.

Dude, you engineering is a fantasy. Your video inspires me.

This guy legit built a bike by himself! 😱😱😱😱 mind blown!

This guy literally redefined the meaning of "DIY" 🤘

That looks tight. A work of art. That was some wicked burnouts you did.

Can't say more than wicked build, even more impressed with detail of specs :) cause so many people don't want to give anything out

Dude, you've inspired me. And I'll tell you how and why... As a guy who loves Hydrogen-powered trucks and cars, I got to say I have a little bit of a liking for e-bikes. Recently my dad said that I could buy his E-Wheels EW-10 from him. I've had so many ideas since then and I decided that I'd build an electric cargo trike capable of at least 90 mph (since I want to use it on the interstate). A few lead acid marine batteries, a high voltage controller (72v-96v) and an industrial 9000w electric motor is all I need to make one heck of an errand runner.

I can't imagine how incredible feeling it must be to ride your own creation and I don't care it's electric. The sound, that can be heard during the test indoors, reminds me of Star Wars which I like :D

I'm so impressed... Unbelievable but you really did it. Respect!

the build from your videos is so unique that i love to watch all of them..

Awesome design, you should try to build an electric dirt bike next. Something futuristic like your other builds. I love your work. Keep them coming.

Wasn't expecting you to literally build one from the ground up, manufacturing nearly everything in house. Incredible video, if I only had a tenth of the skill you have I feel like I could achieve so much.

im not sure whats is better, your awesome video or the awesome explanation description with all tech information and specs... you did it very well sir with lot of patient and love, not speaking only about the motorcycle but the entire video. got my respect and my like. Please continue the good work :)

My personal next project is developing a onboard computer for my own bike designs. Including color screen but the goal is monitoring and accident mitigations. I am working on tire and environmental scanning using LiDAR so here we go! Great job brother!

Son: I want a motorcycle Mum: We got motorcycle at home Motorcycle at home but this time it’s actually a badass beast of a machine: ...

This something that everybody should watch on youtube

riding that bike for the first time must have felt amazing! great job man, i wish i had half your skills :)

A well utilized lockdown, you're a genius bro!

Most build I have watched are just people adding kits to existing bikes , this the first time I've seen someone actually build the bike from scratch! Awesome.

this man made the whole build process look like it was as easy as building lego sets

This is amazing 😻 I don’t have the skills for it wish u lived closer 😂 thanks for sharing with us keep up the awesome work!!

Awesome job. Definitely earned a subscribe. Watching you do all the different jobs yourself reminded me of my father.

Dude, you're such a pro!! I can't even imaging how hard was to plain all off this before you even start to cut the first piece. What a great job, thanks for sharing, this is so inspiring.

I once tryed building a motorcycle in 30 minutes - it never got finished - respect!

I'd have done a few things different aesthetically but I never will because I lack the raw talent. I recognize an artist when I see one. Kudos dude.

Here is a Real Master! İ watched with admiration 👏🏼

This guy can built a motorcycle brand

This thing is awesome! Can't wait for something like this that comes in a "kit" where you can order, they send you all the parts, and build at home will simple tools. Great video!

SENSACIONAL!!!!! ADOREI! Aqui no Brasil se um cara fizer uma dessa não consegue nem sair da garagem muita burocracia!!!
