I'm a 70 year old american and I love watching you guys!!!! You are so smart it baffles the mind. I used to race cars so I know what it takes to make projects like these-thanks for sharing and inspiring!

Dude! That's a 60mph pedal bike home built. Great job. I'm impressed I love projects like this.

Your instability is due to the battery placement being mostly rearward. It should be redistributed to be closer to the center of gravity for greater stability

Not gonna lie i thought this was a fake video, but when i did my research i found out that alternators, in fact, can be used as motors, Great work, i'm gonna do this when i get one on my hands

Never give up your creative fire but absolutely do not be afraid to learn proper technique from the Old pros... Seek out all the retired old men in your community who once did machining an electrical work their knowledge base is priceless, and many have libraries of reference material books that they used for their careers. Those libraries now sit gathering dust, and many of these Old pros will want to bestow those gems upon you.... They are especially priceless, because they now represent lost knowledge and they are usually out of print for several decades...

I've avoided getting an electric bike for years because nobody made one with the power and range I wanted. You just built the one I've been looking for.

You guys are real creative,the world need people like you.thinkers and innovators.much love from Tanzania

Making it gear driven is absolutely wild. If I were you I'd space the alternator back and put on a toothed belt to drive it. This was an awesome build!

Modify the sterring stem ,add caster. Adjust rake and trail angle. For stability Or build a new frame. Keep the position of battery more towards front wheel for more cog

Life should be as easy and simple like this guys, reusing everything that normally will end in our landfill is a great accomplish. Thank you.

DIY King, Good day, This is the 2nd video on Alternator conversion of you Demo's & your sincere efforts, your try to find out is 100 % correct, trial & errors always in the game, keep it up, good luck.👍🏿

You guys have some skills. Machining, welding, and even building your own batteries. My hat is off to you.

I love the fact that you went through the trouble of making your own battery pack. It’s a detail many would have not done.👍

Shout out from California. You guys are amazing. How you say everything correctly is making my eye twitch lol. Keep up the awesome work guys!

thank you for not having some bassy music for the intro! i really thank you

great design/execution to pull it all together. Love your re-purposing of materials.

Didn't know there was such a thing as an 800 amp alternator out there for a 12vdc system. Learn something new everyday.

It is the weight of the alternator on one side of the axle that makes you ride. It would be necessary to put an object of volume and equivalent weight on the other side so that it could roll normally. It will even be much more stable than before!

Amazing, simply amazing. Your ingenuity gives me hope for humanity. Keep going!

great job guys specially making a brush-less motor. you should start a business to convert bicycle into electric cycles. Well done boys keep up.

The build is interesting, but I don't see how this is a 10,000 W alternator (per the video title). For one, you have a 200A board controlling it (which is roughly 12V x 200A = 2,400W). And from what I see, that is a 150 or even 100A alternator, which is 1800 to 1200W. Even with modifications which will bring the power lower still, it is a nice build, but I think you are off by a factor of about 10x.

Great video guys. Much appreciated. Yes, do a video on all the conversions and their pros and cons!

Wow. That is crazy speed for a bicycle.

A totally awesome build! Thank you for sharing.

Bravo! You guys will go far, just keep thinking and keep things open source!

Insanely fast for a converted altenator good job man

WELL DONE GUYS... I did something similar with a weed wacker 2stroke gas motor on my granddaughters Barbi jeep lol... she absolutely loved it.

i loved how you used alternator instead of buying expensive hub drives

An excellent project. Enjoyed it thoroughly. Would love to see more technical specs in the future. Thank you.

That is excellent innovation, craftsmanship and great team work father and son...just wonderful to see..thanks guys...

YES PLEASE !!! Looking forward to the making process !!

I have enjoyed watching you fellows at work on this project, multiple skills and the the accent is entertaining, sounds like Roz ( the guy from Big Bang ). You'll do well 👌👍

Nice to see something on the road and working...most of my ideas don't make it off the notebook page. Good to see your generation with a full understanding of what it takes to bring a project to fruition. Excellent.

Man! I loved this show! You guys are nailing it! Keep at it. You guys are living the dream life.

You're super smart and lucky because you have a nice supply of resources for your parts

You guys are DIY Geniuses. Way to go.

Wow lads. That is absolutely fantastic. I would definitely like one on my bike. Great video. Keep up the great work. Take care brother 👍👍👍👍👍🥇

You guys really know your stuff that bike is amazing with that set up and the range it has if great. Will definitely watch how you converted the Alternator as I came across this by chance.👍

You guys are awesome! From Florida we send our love,🤟🏻

Excellent build.

I managed to get a much more usable result with my e-bike conversion. It will comfortably ride at 80 kmh+ without any wobbles. The only downside is the motor will overheat within a few minutes at that kind of power level. I mostly use it up to 60 kmh and it will beat cars at the lights easily.

I think the project represents thinking out of the box, maybe out of the entire workshop, and it looks like you guys have a lot of fun doing them. That is the best part of your videos. Thanks a bunch.

Truly Impressive and FUN

That is what I'm talking about ! Great work ya'll keep up the great videos.

I love what you guys have done here. Opening doors to new possibilities. Thanks so much.

You guys rock!!! No truly as a fabricator mechanic I like your work very clean strong and precise with limited tools!! Super smart!!! Love to see more!!!

that looks so much fun to ride!

Man you're so creative that's very talented

You guys are amazing thank you so much,,, people think this stuff is easy they are crazy you guys are modern path makers!!

It looks like soo much fun working with you guys. I wish I could spend a day inventing/building with you. Thank you for sharing 😊

Great build I'm happy I found your channel

Live for good and your imagination and ideas will be used by many someday...good luck in your future experiments.

I am soooo happy I happened upon you and your videos!! You both are awesome to watch and to learn from, and I love the bits of humor tossed in for fun. Please keep posting your genius for us all to learn from. Now I want to make my own E-bike!

Love it, i also can see that the bike test was loved as well, great project and great potential for grander projects. But the key lesson here is the amount of upscaling reclaiming and repurposing that has gone into the project so far.

Awesome video dudes, a great way to get around and we get to screw big oil for a change.

Dude what a cool concept. This is the most badass ideas I have ever seen. CRAZY COOL.

As a safety measure, your car speedometer probably shows your speed higher than it actually is (in some places the speedometer is allowed to show a speed up to 10% higher than the actual speed, but is not allowed to show a slower speed). Your phone GPS speed is probably more accurate.

This is so awesome on so many levels!

Brillant idea makes sense using the alternator to recharge battery so good

I'm a 72 year old American, and I think it's a cool build.

At around 11 minutes. Says it all. The smile is an indication this thing kicks some arse. Well done.

Get some vice grip clamps for your drill press! I use them all day at work

Perfect job guys!

Love the creativity, Love the language selection because there's a lot of viewers not only for Indian. Love you from Philippines.

I love watching the things you guys build. Very smart and great engineering. Keep up the great work.

Well done for your brilliant effort. May I suggest a couple of things. I would look at mounting the alternator by the pedal area and using a belt drive or similar to the rear wheel therefore giving you a more centralised mass. Following on from that, the battery pack would be much better slung under the main frame spar and would help with stability for your bike and reduce the speed wobbles experienced. Your efforts are nothing short of inspiring and you guys should be very proud of yourselves, just centralize and lower your overall mass for a much better handling bike. Front forks would also be worth changing to damped forks instead of rigid. Subbed, and sending you best wishes.

Absolutely fantastic mr. Xavier

Awesome job guys!

Great build. Would be awesome to see what top speed could be achieved in case you used a racing bike frame.

You should put a small water reservoir heatsink for a cpu on the speed controller and let the thermal differential cycle the small amount of fluid, and it would get rid of the air gap inside the controller and allow more heat transfer to the heatsink you added

Great Job! Excellent Video

Great jobs guys, thanks for sharing this.

You must always use lubricant when drilling through metal, steel, aluminum, iron and stainless, as well as drilling within the proper speed and feed ranges

Beautiful and very refreshing to know there are still individuals out there with a freaking brain, not just waiting for the delivery person after pressing a button. Thank you, thank you so much. Let’s keep this going. Maybe it will inspire someone to get up off their lazy ass and actually do something.

Awesome job guys.. Keep on doing all your experiments because they will help the World 🌎 😊😇

Absolutely sick video, that thing is pretty quick!

Great video well presented . It's nice to see the teachers who not only teach , but actually do. You guys make the world a better place in every way . Peace : )

Your friend reminds me of how much i miss my longer hair. Its the perfect haircut for a man, lookin all suave and debonair.

DIY King.. Rocks big time

Frankenbike! Love it. Super creative and looks dangerously fun. I think the weak point now would be the wheel/tire dexterity at those speeds. Not to mention the breaks!

Sure would love to see a three wheel bicycle also set up the same way but you would need add a single wheel bar behind going between tires in back because the sprocket would need to be centered shaft. Love the idea here

Real insane product man, enjoyed watching it and imagined the possibilities, thanks a lot

BEST PAKISTANI TECH CHANNEL

wicked project, well done!

Brilliant. This is what innovation looks like!! You guys are great!

Hi, 7 years ago I was working for a small company that was selling electric bicycles. We converted normal 26´´ mountain bicycle into a e-bike. 1000 W motor was able to ride it at constant 45km/h. Please get a bicycle with much bigger rims and than try it again.I think you will be able to go 100 km/h without any problem.

man, I m so impressed!

Great job guys! Nice conversion. you guys made it all look cleanly done to with everything tied down and in it’s right place. I think I’m going to try this conversion myself soon.

engaging Li-Po battery pack without BMS to run a motor is dangerous dude. Li-Po is very flammable when its leaking

It's a great invention thank you my brother.

Definitely this is really cool stuff I think it would be great to see this cool ideas for e-bikes you have.That speed was awesome..

I bet the looped small wire you used to connect the cells in the battery get pretty hot under 30+ amps of continuous load, unless you have multiple sets of cells in parallel. Nice build!

Great job guys you guys are very talented I am an electrician and also an inventor and engineer I love your concept and what you have done I believe you have a very marketable item and I believe you should apply for a patent to what you have done to protect your work if you have not already done so!

Great project! And bonus points for that cockatiel screaming in the background! I've had many 'tiels throughout my life and that sound is not only unmistakable, but also makes me smile :D

Dude you are so smart good job keep going

Great projects. I'd love to see the details of the convertions

With the current gas prices, I need one of these for work.

Without thought, there can be no ideas, thus no creation, innovation, or invention!❤

Awesome science dudes. Great work..

This is absolutley amazing, converting a bicyle to an electric bike witha a car alternator this is just mind blowing you are such a talented person, hope to see more improved version of this project, keep it up
