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'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

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.

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

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

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.

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

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!

all you need now is to not let the back wheel flex , spoked wheels have a flex tolerance and your motor is close ,but this a wonderful idea and looks fun 😍

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.

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.👍

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

put the setup into tricicles and make the batteries modular good job tysm 4 sharing!

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

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

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!

That's super clever. Well done for putting an old alternator to very interesting use. To keep the controller cooler, consider adding an aerodynamic ducting to the heatsink to channel air over it as you ride, perhaps adding a quiet Noctua or Arctic Cooling fan to help with the air flow 👍😉

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.

I’m a white guy from the United States , I’ve always been impressed with you East indie guys as your creativity is very impressive. BTW- The relationship you have with your little buddy is really cool, keep up the good work guys. God bless.

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

I think if you could get the weight of the battery in the frame area, you will get more weight on the front and stop the wobble. NICE DEATH MACHINE! Super Cool!

Great job. Very creative. My only suggestion would be to use the guard for the grinder to be safer

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

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.

Here's a suggestion to improve the handle and reduce wobbliness. You can use dampers made for e-scooters. It's supposed to reduce the shakiness of the handle at high speeds.

Vibration is caused by dynamic instability. You can correct that by using dampers ( shock absobers).

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

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.

Im a 109 year old American and I think this is good

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 👌👍

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 😊

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

okay boss I want to see what you can do with this idea . using this alternator / engine & using the big wheel idea from another video on you tube titled "this is not a bike / DIY" I'd like to see you build a reverse Tadpol style recumbent trike. My idea would be to have tween chain drives from this motor to both sides of the big rear wheel with the motor located behind the driver's seat. battery to be mounted in a housing that would be built over the rear big wheel . I think when you see that video you will be able to see my vision. As the youngsters say it will be sick! another great build video as always many thanx!

love the project. Only thing I would recommend is a battery management system.

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

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.👍

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

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..

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

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.

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

Would like to see you guys try it on an uphill so we'll have some idea of the power it delivers. Nice project! Keep it up guys.

A totally awesome build! Thank you for sharing.

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.

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!

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

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.

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!

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.👍🏿

This needs to be divided by 10. 1000 watt, this is the maximum you will get from this device.

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

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.

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

definitely make the videos because it establishes a record of your works

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

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

A shorter bike stem will give you more control. Wider handlebars too but you may not want them too wide in traffic.

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!!!

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

Thanks for sharing, enjoyed your video very much! Question: Did you had to do any modification to the permanent magnet alternator?

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

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.

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

Love it, you have a good grasp of Watts laws, wish you could build up one on a cruiser frame with fat tires

You're created a rocket 🚀 Thank you for sharing your experiment with us It's funny that it's so rare in so called "modern advanced" societies that anybody wants or knows how to build anything, they are completely unable to do anything... So who is more advanced?

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

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

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

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

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

Awesome 😎 i think the wobbling you mentioned is due to improper weight distribution. The alternator and the battery is on the rear wheel. Also, the rider sits closer to the rear than front. You should aim for a weight distribution of 50% for each wheel.

Really interesting build. I want to do something similar to a former pgo two stroke scooter by replacing the top end with an electric motor keeping the variator. Need about 7k rpm. I'll keep you informed

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

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!

As a former mechanic of 26 years, I'm impressed with your ingenuity!

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

Great work 👏 I love what you did here! This is the second time I see you do this same conversion. Someday I'm going to buy one of these bikes from you. 😊

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

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!

You are lucky to live in a country that allows creativity , most places in north america you would recieve huge fines , everything out of the ordinary is over-egulated.

Nice Job Done, By working for new project one can get new new idea's and can utilise another new idea which automatically comes up in your mind n can be useful for some more new new projects, Keep Up

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.

Wow so interesting to see how you both work on this, and gives me hope that the idea I have for a modular designed enclosure three wheel electric bike could work.

these guys are living a life that was a dream of mine.😊

WOW the Batterie is vor me to DANGERUS! All old Handy akkus? wow

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

Very well explained. I like the enthusiasm put into this project. My question is, how long do you need to fully recharge the batteries?

thanks guys for sharing your experience

thats why you need to clamp your work piece when using a vertical drill 3:35 when you use bigger drills and heavier workpieces you can actually break your arms or back if you get hit

you want to get a steering control on there perhaps a hydraulic piston for the left and right to slow the steering to remove that steering issue

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

Great build I'm happy I found your channel

Great video very fun. I enjoyed all I thought your friend looked like he was enjoying the ride... Take care my Friends

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

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

Very good, stay safe on ur contraptions, would like to see this build with a belt drive, the motor and battery mounted in the main triangle of the bike including for better CofG, all that weight over the back wheel will damage the rear wheel and ur back, v good video, I enjoyed it, ta.

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

This is so awesome on so many levels!
