why didn't you put the two back wheels side by side? and used a non-hub motor (a standalone motor + sprocket and belt/chain) you would've gotten a lot more power
You’re amazing. I wish you’d wear helmets all the time. Not just for your safety but for all the youngsters watching that want to be like you. I really liked some of the music you used.
I thought this video was going to be crap. But after watching a few minutes, I couldn't stop. Nice welding on aluminum. I like your impromptu engineering. But you really need to wear some safety gear especially on an unproven vehicle. Where's the license plate? Would be nice to do this legally. Can't really condone the speeding especially on an unregistered vehicle. You should really be on a private track. They are cracking down on e-bike and scooter laws in many states because of antics like this. Don't make it bad for the rest of us.
I really hope they read comments. I loved the video. But I cringe every time I see no helmet. It should be mandatory to see what happens to the human head with even unprotected ground level falls. I've treated some seriously horrific head injuries from no helmet wearing. And seen many more at the coroners who never made it to me alive. I spent years riding without a helmet until I had my first coroner rotation. Probably the biggest source of organ and live tissue donations are non-helmet head injuries.
@SilverShadow2LWB We're your sense of adventure and entrepreneurship? You think the Wright brothers had a license? Hell I don't think they even wore helmets. More like bowler hats.
I lost my dad when I was 25, we would stay up all night sometimes lacquering furniture and just doing a bunch of different projects together. I shed some tears when your dad stayed up all night polishing the scooter for you. I know that type of love, and how he was probably so excited to make you proud just as youve made him proud. I love watching your channel, it reminds me of those great times with my dad... Great job on the super scoot man!
incorrect, the holes are to release trapped water vapor which can prevent the brakes from functioning correctly. Floating discs and calipers are used to deal with warping
For any future battery builds *please* buy a powerful spot welder and do the copper nickel sandwich technique so you don’t have to roast all your cells with the mega soldering iron.
I really hope I'm wrong but this pack is a ticking time bomb that's gonna burn sooner or later. The cells are definitely cooked, every single one of them.
Listen to this guy! Discard the battery pack immediately or at least rebuild it into small battery packs these batteries likely had their fuses melt together. There's no per battery fuses on these so the second one of those lose resistance the battery will quite literally explode like a bomb.
From my experience building high-power lithium packs, you don't want any gaps between the cells. They did just fine copying the RUclipsr who builds packs. Those packs won't get hot. In fact, they should have fully enclosed them with heat shrink and a G10 case over that. They are not using anywhere near the power output of those cells.
Let's not even get started about the lack of safety gear while riding, as a biker all i could think of was one pothole and huge pieces of skin getting scraped away😭🙏
@FarmerFpvcorrect me if im wrong. But 30kW per battery at 200 cells per battery is 150W per cell. Thats ~40Amps at 3,7V. Looks like they push those cells pretty far.
Then it went again when you saw how he was standing on this scooter, 36:54 - damn... one leg should go near back wheel, position similar to snowboard, this gives sooo much stability at higher speeds/accelerations
Fantastic build ... however i am concerned about the heat damage to those cells. Spot welders are used for this very reason. Please be careful with those packs and never leave them unattended during charging. In the future it would be best to combine parts of the electrical, for example if charged correctly there is no reason not to combine the packs (with fuzes) this will further increase range... The speed controllers you have used should be able to connect together on the throttle input so the same ammount of power is sent to the wheels, with seperate ESC's the power is not uniform. Most high end controllers will alow interconnection and even power adjustment to individual wheels. You should have only one battery monitor to get more accurate range readings and as above you only really need one key to operate all the solenoid units. With regards to your brakes, check to see if the speed controllers support electronic braking as most of them do. If you make these changes you can simplify your wiring, make is safer, get more acurate range and battery readings and improve the performance further. I don't mean to be critical i just think you could improve a few things though the heat from that soldering iron on your batteries does worry me. Other than that I think you did a fantastic job engineering the frame and all the metalwork, especially considering how hard it is to weld aluminium properly. I hope you get years of fun on that thing, please do not fall of at those speeds 😂
It did not take long to write at all. I think it is a brilliant bit of engineering (aside from the battery packs) that could be improved with simplification and a combining of systems. This would reduce complexity, reduce weight and improve reliability. The frame and mechanical aspects look exelent, its the electrical system that could be improved in my opinion. Sorry if you think it is too long, nobody is forcing you to read it.
@DJHeroMasta Hail no. So much more can go wrong on a scooter, I know cuz I've crashed with an electric one and broke a few bones, and it wasn't even going that fast it's just cuz it slid out from under me
this video really exemplifies the engineering saying "any idiot can build a bridge that stands, but it takes an engineer to build a bridge that barely stands"
@celivalg Overbuilding by an engineer is the original dirt bike axle size. There's a reason it's that thick. If anything, this is quite a bit underbuilt - especially the brakes, the electrical safety, and potentially a few other spots. The lack of any safety equipment also means the usual thing we see in gear-free motorcycle crashes if anything goes sufficiently wrong. That battery's also a fire hazard...
Holy.. You use a spot welder because those battery cells do NOT like heat, and the small soldering iron you used for the first copper strip was already dangerous. You're very lucky you didn't burn the whole place down
I was HORRIFIED when they decided to use that mammoth of a soldering, im genuinly asking how it didnt just turn the next 3 blocks into a giant metallic fire.
Yeah I almost feel like this whole battery build is just rage bait. Other than the fact that HE LITERALLY SOLDERED TO THE CELLS AFTER SAYING THAT'S DANGEROUS (it's not like that tiny nickel strip insulates the cells from heat in any way), he also then crossed every single balance lead. This thing is catching on fire, and I hope he reads our comments and throws it away before it's too late.
I like how you were like "I'm not wearing a helmet because I didn't think it will be THAT fast with the single motor" then went full throttle with all 3 motors and no helmet
Qualified Welder here, please for your next one wrap all your edges and ensure you have no inclusions, might possibly be easier if you weld the majority with the mig and clean up the welds with the Tig, just wanna make sure ya'll are safe! amazing work honestly though guys this is absolutely insane!
I like all the security measures you have taken testing it! Zero helmets worn 24:10 🎉 Hopefully the road with 35 limit was closed. But who I'm trying to fool 😂
btw, you couldve made it shorter if you had a seat over the middle wheel. it would be smoother, comfyer, and would probably be safer. anyways, this it really cool!
Super cool! A few suggestions tho. Firstly, consider putting a heatsink on the batteries. It’s probably fine but if you’re drawing a ton of amps (eg. Going up a hill) the you might run into thermal problems. Secondly I would try out regenerative breaking. It should slow you down better and also has the advantage of recharging the batteries slightly. This way the mechanical ones can be a backup if the regenerative brakes fail. Thirdly I would buy a nice 3D printer (Bambu labs is great for beginners to 3D printing) and print some guards on the front to improve aerodynamics (PETG OR ABS would most likely be suitable). Finally, I’d imagine that this could go a really long distance on a single charge if you make some adjustments to only toggle on one motor. Again great job on this!
This is the craziest thing I think I have ever seen, the battery building, the saw break and a scooter of 90 f***ing kilowatts!!! It is a miracle you guys are alive, thanks for the great content👏👏
I would put a seat on this thing as the human body isn’t too aerodynamic standing straight up like that into the airflow. You could also probably going flying really easily standing up and seriously hurt yourself. Even if it’s not a scooter that way you’ll probably be safer Note: I’m not an doctor, aerospace engineer, or engineer in general so I might be wrong
17:11 i’m pretty sure you’re not supposed to solder connections that close to the cells it generates so much heat it can degrade the cells That’s why you spot weld the nickel instead of soldering
keep this in mind for future builds if those unwired motors phase wires touch each other it will act as a brake and can cause an accident 23 mins in that could be a bad crash
The wind only felt like it was really slowing you down when you started getting really fast, but it’s slowing you down a lot even at 40. The high torque of the motors hide it well, but scooters are just so tall.
Phase 1: 24 hour, overnight challenges etc. phase 2 to now over 2 million subscribers I’d say you’ve accomplished your goals of growing the channel. Keep it going Chay for President
Hey president Can you make a another channel where you put out a video of each of your build cause i am pretty sure you are condensing hours of content into 30 min that is cool af but if someone wants to see more about it i like want to see about this build , you can put a long video on that channel without much of editing just raw footage with commentary ( i love your commentary btw ❤) please give this idea a thought 😊
Your battery pack is a time bomb. Please, discard it asap and build it by making small packs that are chainfed into eachother, through a fuse, each of them. Sorry for my poor english.
Som people you talk about explosion like this guys were not following protocols from other video,nothing much,the are goodbin using their mind only,and you are filled with jealous,make yours lets us see if it can beat them,just be quiet you wont die,appreciate their effort,😂😂😂😂😂😂😂😂😂😂😂😂😂😂
Dude I searched for your channel hoping to see a new video, checked if the notification was turned on. It was, lol 😂 few hours later y'all dropped wtf I literally manifested this
Can you try using just two motors and two batteries? Reducing the overall weight might actually improve speed and efficiency. It could also be worth considering the law of diminishing returns. ❤
@NoNORADon911 you think that, but in reality they would accelerate 2x faster if they slowly leaned into the throttle and maintained grip in the tires, in reality they didnt even show half of that things acceleration
For the copper on your DIY battery, you should have placed a strip of nickel above the copper, and then spot welded like normal (the nickel strip on top of the copper makes all the difference when spot welding the two). Soldering is very bad for cells (the heat kills the cells). But nickel/copper sandwiches are quite common these days. Also, the balance lead should NEVER cross each other. Wear and tear from vibration can cause two crossed balance leads to short and that leads to all of the fires that you see on ebikes (cheap Chinese battery builds). PS: Your brake rotor from a saw blade was genius :-)
@SurfingWithStyle1 No that's common knowledge of building battery packs. The reason you don't solder to cells is because overheating a cell can get it to thermal runaway (basically it can catch on fire), and also too much heat can damage the cells and they might catch on fire later, after many cycles. He basically soldered to the cells, just with a really tiny strip of nickel in between. And he's also right about the BMS balance leads, shorts are one of the main causes of fires in packs. When a battery is shorted, it basically dumps all the electricity it holds into itself, which again causes thermal runaway.
Yep. People complaining it didn't technically hit 100... this is a 100mph scooter, they just have to add one small aero piece to the front to get it there.
Yeah not the best, haha. I like an explanation with a water hose better. Volts are the electrical pressure pushing electrons, similar to water pressure in a hose. Amps (Amperes) are the rate of electron flow, equivalent to the volume of water flowing through the hose. High voltage pushes water faster; high amps mean a larger pipe is delivering more water volume. (from battle born batteries website via AI haha) Resistance in the wiring would be like a kink in the hose.
Thanks for posting, you have taken on a pretty adventurous project. You need to use shield gas !! You might have wanted to talk to some DIY experts in EV battery and bike fields. As using a huge soldering iron on lithium cells is a huge no no and probably permanently damaged all those cells. And you should speak to a motorcycle builder as you have changed the rake on the front wheel and that looks scary. Good luck
Fantastic job to everyone involved! The average viewer probably wont realize just how many complex engineering problems you all had to solve to make this thing actually work. You should be very proud!
Just found your channel. As a 41yo with over 20 years experience in metal and automotive trades. You guys do really well with the basic tools at your disposal. Awes build. Ride safe guy's.
That would be pointless. The reason for a kill switch is to turn off the motor if you get thrown off a boat so that it does not drive away. The scooter requires you to press down the acceleration to keep it going, so it would stop automatically anyway. And if you are thrown off at that speed, it is the least of your worries.
@grischa762 I mean if the kill switch is for all the 3 giant batteries than I'd call it useful. If they get thrown off the batteries would switch off making the bike safer as it drives off solo(as in if it falls or crashes later)

yo dude nice vid lol can i be in next?
why didn't you put the two back wheels side by side? and used a non-hub motor (a standalone motor + sprocket and belt/chain) you would've gotten a lot more power
you should add a chair to it and something your feet can stand on so you dont fall off
Colby must be glad.he didn't have to build any cabinets
He might not have had to build cabinets but I am 100MPH sure he was adjusting the weight in his drawers!

@PhilChurning hoprfully not
@maxerioplayz3737whats wrong with you kid? You think this shit is funny?
You'll realise it once you loose your father like i or this person did
I did meth with my dad too, rip in piece pa.
WARNING - The reason most brake disks have holes is to prevent warping when they get hot
27:21 When he put holes in them, I thought he knew. Then he wrote from the bottom, "I put it for decoration." 😂
@AYMEN.16 27:21
@mikoaj3120yes thanks
incorrect, the holes are to release trapped water vapor which can prevent the brakes from functioning correctly. Floating discs and calipers are used to deal with warping
@C@Casper-NineteenEightyFourincorect the brakes have holes in them so the nutrient forces dosent get to powerfull and the brakes dosent break
You HAVE TO cover those vents with a grid or something. If a stone goes in there at 60 mph + - it’s game over
big fire?
@supertornadogun1690that’s the lucky end. It could cause you to crash doing 60 mph+
was gonna say
*Top Comment right here!* I didn't even consider that. Was too mesmerized by Pop's Mirror Finish!*
@supertornadogun1690 im surprised Neanderthals still exist
35:58 Finally! Throughout the second half of the Video I just kept thinking "Wear PPE, please wear PPE"
My grandma was Skuurd too...
*Flys past cop at 100 mph on a scooter* 🤣🤣
in a 35mph zone.. instant arrest for felony reckless driving.... when they inevitably find out who it was that outran them.
Thats 160 kph!
gets pitted lmao
96.4 actually
@GrillerWarfare is in milles 96.4 milles per hours is 160 kph is a conversion speed imperial to metric the school don't learn you this thing
For any future battery builds *please* buy a powerful spot welder and do the copper nickel sandwich technique so you don’t have to roast all your cells with the mega soldering iron.
I really hope I'm wrong but this pack is a ticking time bomb that's gonna burn sooner or later. The cells are definitely cooked, every single one of them.
@ejtako For sure. Best case their capacity just got decreased a bit.
Listen to this guy! Discard the battery pack immediately or at least rebuild it into small battery packs these batteries likely had their fuses melt together. There's no per battery fuses on these so the second one of those lose resistance the battery will quite literally explode like a bomb.
Came here to say this. I was terrified that while making it at least one cell would catch on fire.. that is before how damaged they will be now.
indeed . the good thing is they likely cooked all the cells the same :s
A grinder and paint, make me the welder I ain't!
BRING IT TO A DRAG RACE!!!!!!
well bring the paramedics💀💀
He’s aware…
He's fully aware nowwwwwwww
@RandomFilters111we'll
give it some body panels to make it more aerodynamic and to block the wind from your body. then take it to the strip
15:38 That cell arrangement is horrifying 😭😭🙏🙏 Zero f*cks given about airflow or ventilation.
🤐🤐
From my experience building high-power lithium packs, you don't want any gaps between the cells. They did just fine copying the RUclipsr who builds packs. Those packs won't get hot. In fact, they should have fully enclosed them with heat shrink and a G10 case over that. They are not using anywhere near the power output of those cells.
Let's not even get started about the lack of safety gear while riding, as a biker all i could think of was one pothole and huge pieces of skin getting scraped away😭🙏
@FarmerFpv Yeah they won't get hot, its only 90.000 watts, no biggie
@FarmerFpvcorrect me if im wrong. But 30kW per battery at 200 cells per battery is 150W per cell. Thats ~40Amps at 3,7V. Looks like they push those cells pretty far.
bro is going 100mph when the speed limit is 35
My heart beat was crazy when I saw them soldering and kinda melting the batteries heat shrink🚨
Then it went again when you saw how he was standing on this scooter, 36:54 - damn... one leg should go near back wheel, position similar to snowboard, this gives sooo much stability at higher speeds/accelerations
@SanFable Literally bro... I ride a 50mph scooter every day and this KILLED ME to see him standing like that
What I hate about scooters is the handle bars being higher than necessary, like, I’m not a fucking Harley rider.
@Mr_GhostRiderUnreal higher handlebars give you better leverage and stability. That's why.
Fantastic build ... however i am concerned about the heat damage to those cells. Spot welders are used for this very reason. Please be careful with those packs and never leave them unattended during charging.
In the future it would be best to combine parts of the electrical, for example if charged correctly there is no reason not to combine the packs (with fuzes) this will further increase range... The speed controllers you have used should be able to connect together on the throttle input so the same ammount of power is sent to the wheels, with seperate ESC's the power is not uniform. Most high end controllers will alow interconnection and even power adjustment to individual wheels.
You should have only one battery monitor to get more accurate range readings and as above you only really need one key to operate all the solenoid units. With regards to your brakes, check to see if the speed controllers support electronic braking as most of them do.
If you make these changes you can simplify your wiring, make is safer, get more acurate range and battery readings and improve the performance further.
I don't mean to be critical i just think you could improve a few things though the heat from that soldering iron on your batteries does worry me. Other than that I think you did a fantastic job engineering the frame and all the metalwork, especially considering how hard it is to weld aluminium properly.
I hope you get years of fun on that thing, please do not fall of at those speeds 😂
He could solve it with an auto disconnecter
How long did that take you to write
Nobody is reading all that
I read all that
It did not take long to write at all. I think it is a brilliant bit of engineering (aside from the battery packs) that could be improved with simplification and a combining of systems.

Whyre u everywhere!??????
@veerkarpe2731fr 😭
Genuinly you spend too much time on youtube
liking this comment as an investment
@veerkarpe2731that's called being a bot
You guys need to install windscreens, make it more aerodynamic and try again
YO! That would be so much better
Honestly to me that would defeat the purpose of the scooter. Could have tucked better.
then also add 2 extra wheels, and then its car!
@stuntwastaken1074 wha- yo bro, i think you mean 1 more... right?
It wasn't stopped by the drag they had probably put the speed limit at 100 themselves
Brazilian channel Letra J moded a comercial scooter and reached 120 mph
I don’t think I would go 100 mph on a electric scooter no matter how much gear I have on but your really brave for that bro
Not that much different than riding a bike yeah?
99.4 mph
@udiditdan It would've definitely went 100mph if he squatted down but doing that at that speed could be dangerous
I would of wanted to stand sideways to reducew the air resistance, they probably would of gone faster or hit 100 sooner if they did.
@DJHeroMasta Hail no.
So much more can go wrong on a scooter, I know cuz I've crashed with an electric one and broke a few bones, and it wasn't even going that fast it's just cuz it slid out from under me
"and your alive!!) 💀 37:58
As a dad, i can relate😂
this video really exemplifies the engineering saying "any idiot can build a bridge that stands, but it takes an engineer to build a bridge that barely stands"
that is kind of mean
@whatever45q4ok……….
@whatever45q4 not really, they know that they don't know everything, so they don't take risks by overbuilding
The engineer might have actually put brakes on it too. Those little brakes are basically nothing.
@celivalg Overbuilding by an engineer is the original dirt bike axle size. There's a reason it's that thick. If anything, this is quite a bit underbuilt - especially the brakes, the electrical safety, and potentially a few other spots. The lack of any safety equipment also means the usual thing we see in gear-free motorcycle crashes if anything goes sufficiently wrong. That battery's also a fire hazard...
It's just diabolical that there is a speed limit 35 where they were testing 34:22
They were testing in Mexico. I put that sign there as a joke. Capeesh?
Exactly HAHAHAHA
Yup reckless driving speed and this scooter requires a motorcycle license, and registration/tags now.
You guys should honestly try beating the world record, this scooter already comes in punching distance
Holy.. You use a spot welder because those battery cells do NOT like heat, and the small soldering iron you used for the first copper strip was already dangerous. You're very lucky you didn't burn the whole place down
Yeah you're definitely not supposed to solder on cells especially if you have lots of thermal mass (the copper and the solder)
Came to the comments just for this 😮
I was HORRIFIED when they decided to use that mammoth of a soldering, im genuinly asking how it didnt just turn the next 3 blocks into a giant metallic fire.
I just hope those were protected cells and maybe they were accounting for the price
Yeah I almost feel like this whole battery build is just rage bait. Other than the fact that HE LITERALLY SOLDERED TO THE CELLS AFTER SAYING THAT'S DANGEROUS (it's not like that tiny nickel strip insulates the cells from heat in any way), he also then crossed every single balance lead.

I like how you were like "I'm not wearing a helmet because I didn't think it will be THAT fast with the single motor" then went full throttle with all 3 motors and no helmet
26:20 as they say, "a grinder and paint makes me the welder I ain't"
Nice one
33:33 why no helmet?
Helmet was in his pocket
@giovaneantonychiapetti2801😂

amazing video but a friend of mine literally got arrested for driving an electro scooter at 113 mph (just a regular one but heavily tuned)
Should dipped on em
that's impossible lol he bullshittin ya
23:17 please where a helmet my man 😂
That waterbottle explanation was so good that even my dumb ass understands it. Thanks mate.
I like all the security measures you have taken testing it!

Yes, I noticed that too😂
Yep god dayum
BRO IK
Dad's DANK.
I watched this video like a normal video, now I’m a proud owner of a gotrax scooter. (They do have awesome scooters)
This is the craziest thing I think I have ever seen, the battery building, the saw break and a scooter of 90 f***ing kilowatts!!! It is a miracle you guys are alive, thanks for the great content👏👏

Note: I’m not an doctor, aerospace engineer, or engineer in general so I might be wrong
Yeah you need a seat or at the very least a forward lean angle 📐. Some raised foot pegs to lock your feet in would be pretty sweet
Aaand youve built an electric bike. A quick one though
@ehodzic155 At least it’s safer
Not leaning on the steering wheel at 100 mp/h is life threatening
The fact that you did that in thirty eight minutes is really impressive!
Whatchu mean bro😂😂
17:11 i’m pretty sure you’re not supposed to solder connections that close to the cells it generates so much heat it can degrade the cells That’s why you spot weld the nickel instead of soldering
New Title: I made a makeshift motorcycle that you can stand up on
21:00 What about motor braking?
😭
28:03 back to the future reference? Maybe?
Make a cart with those motors to go faster without falling off lol
keep this in mind for future builds if those unwired motors phase wires touch each other it will act as a brake and can cause an accident 23 mins in that could be a bad crash
27:17 aand to actualy cool it😂
At this point I'm waiting for y'all to just straight up build an electric car
The wind only felt like it was really slowing you down when you started getting really fast, but it’s slowing you down a lot even at 40.
The high torque of the motors hide it well, but scooters are just so tall.
This guy makes the best nostalgic building videos it’s actually entertaining props to chay 🎉
Doing all of this in front of a 35 MPH speed limit sign is absolutely hilarious 😂😂
Not quite the speed limit. 34:25
im convinced this guy can build anything out of anything

would you ride 99.4 mph on a scooter? I dont thank so
@Jesus_Christ_Ministries still not 100 tho..
@Jesus_Christ_Ministries I mean I would go 83 mph with a EMOVE Roadster but my scooter is only 40 mph since that’s all I can afford
Chay you should race this scooter with the fastest go cart
Hey president
Can you make a another channel where you put out a video of each of your build cause i am pretty sure you are condensing hours of content into 30 min that is cool af but if someone wants to see more about it i like want to see about this build , you can put a long video on that channel without much of editing just raw footage with commentary ( i love your commentary btw ❤) please give this idea a thought 😊
I agree👍
@AndersAnderson-c5c I agree👍 👍
I actually support this. Their uncut videos are actually videos I'd spent hours watching
Your battery pack is a time bomb. Please, discard it asap and build it by making small packs that are chainfed into eachother, through a fuse, each of them.
Sorry for my poor english.
no the batteries were made just fine they built it great,
Explosion boost
Som people you talk about explosion like this guys were not following protocols from other video,nothing much,the are goodbin using their mind only,and you are filled with jealous,make yours lets us see if it can beat them,just be quiet you wont die,appreciate their effort,😂😂😂😂😂😂😂😂😂😂😂😂😂😂
33:45 "Im scared" What about a Helmet and perhaps even bike protective clothing?
Dude I searched for your channel hoping to see a new video, checked if the notification was turned on. It was, lol 😂 few hours later y'all dropped wtf I literally manifested this
Yo ur videos just make dinner better🎉
factsss
And lunch!
Yeah it's my dinner video today
All the meals!!
I'm glad that he's not yet flung by air resistance and wind
Can you try using just two motors and two batteries? Reducing the overall weight might actually improve speed and efficiency. It could also be worth considering the law of diminishing returns. ❤
This is one of my favourite vids yet thanks for the awesome content
men like i have no depression and then polish metal all night long, i like it)
26:20 your Dad is the Goat ❤
Comparing with my parents, they'd be highly alarmed if i did like 10% of the stuff in the video xD Really different material
The front brake is gonna melt😮
this is like if a Motor Bike and an E-scooter had a baby
Ur going to burn those tires down quickly if u keep going full throttle right away, try going on the throttle slowly
That's no fun lol
@NoNORADon911 you think that, but in reality they would accelerate 2x faster if they slowly leaned into the throttle and maintained grip in the tires, in reality they didnt even show half of that things acceleration
For the copper on your DIY battery, you should have placed a strip of nickel above the copper, and then spot welded like normal (the nickel strip on top of the copper makes all the difference when spot welding the two). Soldering is very bad for cells (the heat kills the cells). But nickel/copper sandwiches are quite common these days. Also, the balance lead should NEVER cross each other. Wear and tear from vibration can cause two crossed balance leads to short and that leads to all of the fires that you see on ebikes (cheap Chinese battery builds).
PS: Your brake rotor from a saw blade was genius :-)
How do you know this, are you like a engineer or something.
@SurfingWithStyle1 No that's common knowledge of building battery packs. The reason you don't solder to cells is because overheating a cell can get it to thermal runaway (basically it can catch on fire), and also too much heat can damage the cells and they might catch on fire later, after many cycles. He basically soldered to the cells, just with a really tiny strip of nickel in between. And he's also right about the BMS balance leads, shorts are one of the main causes of fires in packs. When a battery is shorted, it basically dumps all the electricity it holds into itself, which again causes thermal runaway.
@ejtakoyeah but most modern batteries can’t short circuit because of safety switches
@SurfingWithStyle1 They are unprotected Li-ion cells, they're not really meant for consumers.
@niaimack ah i forget its consumer made and not actually built buy a manufacturer
I passed my driver's licence test on a bike that had 30kW engine. This thing is a monster.
20:48 how someone even think about this 😮
Man need big metal circle > man see big metal circle with teeth > man take off teeth > man has big metal circle :D
Closed face helmet and some sort of fairing on the upright steering pillar and I reckon you'd top 100 mph easy.
Yep. People complaining it didn't technically hit 100... this is a 100mph scooter, they just have to add one small aero piece to the front to get it there.
Next video : we are going to make an e-bike
26:50
You were gonna paint the scooter black...
A color that absorbs all heat
Like the heat of 90KW leaving the batteries wasn't enough
Bruh
the expalnation at 15:40 was wrong on so many levels...
Yea dude, my engineering brain was just screaming at the screen
of couse he is not a professional just enjoy these guys work bro
@raj-07-x2zthis dudes vids just make my dinner better
Where's your 100mph scooter?
Yeah not the best, haha. I like an explanation with a water hose better. Volts are the electrical pressure pushing electrons, similar to water pressure in a hose. Amps (Amperes) are the rate of electron flow, equivalent to the volume of water flowing through the hose. High voltage pushes water faster; high amps mean a larger pipe is delivering more water volume. (from battle born batteries website via AI haha) Resistance in the wiring would be like a kink in the hose.

New President Chay video on my birthday! Thank you bro 🫡
Happy Birthday!
Happy Birthday! It's my birthday as well! 🥳
Why are all of your videos so fire!?!
Congratulations. You've just made a Race War's fast and furious electric machine version.🎉
thank you colby❤
pls build something for him
True and Dad as well ❤😊
Thanks for posting, you have taken on a pretty adventurous project. You need to use shield gas !! You might have wanted to talk to some DIY experts in EV battery and bike fields. As using a huge soldering iron on lithium cells is a huge no no and probably permanently damaged all those cells. And you should speak to a motorcycle builder as you have changed the rake on the front wheel and that looks scary.
Good luck
i was thing the very same thing looks like it needs a new more degrees forward.
wait, am i watching president chay with his brother and his dad, or am i watching a more bad ass version of mythbusters
Fantastic job to everyone involved! The average viewer probably wont realize just how many complex engineering problems you all had to solve to make this thing actually work. You should be very proud!
Soo glad to see you wearing the appropriate gear when doing the top speed test!
Just found your channel. As a 41yo with over 20 years experience in metal and automotive trades. You guys do really well with the basic tools at your disposal.
Awes build. Ride safe guy's.
Add a kill switch bracelet (similar to what youd find on a boat)
That would be pointless. The reason for a kill switch is to turn off the motor if you get thrown off a boat so that it does not drive away. The scooter requires you to press down the acceleration to keep it going, so it would stop automatically anyway. And if you are thrown off at that speed, it is the least of your worries.
@grischa762 I mean if the kill switch is for all the 3 giant batteries than I'd call it useful. If they get thrown off the batteries would switch off making the bike safer as it drives off solo(as in if it falls or crashes later)
11:59 leaked your location might wanna cut that out 😅
Oh shiii
W dad mam you are lucky as hell that you have supportive dad like him
0:00 Alredy a banger 🔥
Shout out to your dad Fom one father to another you’re a king among men. I have a great respect for the care and devotion to your children in your tireless support. Thanks for setting the bar.
as a welder, WEAR GLOVES. you are risking skin cancer
I just think that sing says 35mph but they're going 60mph is crazy.... 💀🤯
