In this video I will be having a closer look at the cheapest street-legal E-Scooter I could find on the Internet. It is called the eScooter Street One from Aldi and I will not only tell you my personal opinion about it but I will also upgrade some of its electrical features. That means I will try to increase its speed, range, charge up time and also change the fact that the lights require their own little batteries. Let's get started!

Greatscott!: uses XT60 for hand crank generator project.
Also Greatscott!: uses 5.5mm DC barrel connector to power electric scooter.
That's me :-)
Joke aside, brushless motor ESC can generate quite some transient voltage spike due to the nature of switched inductor. This is an even bigger problem with active or regen braking which often featured on most ESC because you're sending power back to the line. ESC requires stable input supply which can be attained by having an array of capacitor on the input and having low resistance power path to battery to dampen the surge, which I'm pretty sure the 5.5mm barrel connector is lacking of. Just my thoughts :-)
@@Fafnier361 wtf
@@Asu01 I would just connect the batteries in parallel, since that would lower the internal resistance losses. A PTC can be used to limit current if the charge states are wildly different. ua-cam.com/video/snaJxB_psg8/v-deo.html
@@NiHaoMike64 He's not paralleling the batteries. He's switching from one to the other (SPDT power switch).
> Using resistors to drop the voltage
DC-DC buck converter: "Am I a joke to you?"
At least he uses resistors, not sticks or stones
Adding insult to injury, a big fat bundle of resistors, lol
Diode: Am I a joke to you?
@@ihatepokemonthings thats what conrad is for. Yes its more expensive but its there in a day (or two)
@@VincentFischer The lamp probably has a resistor already, since it runs off 3 AAA or AA cells. 3 x 1.5V = 4.5V, while the forward voltage of a typical white LED is 3V. Besides, dropping 42V to 4.5V via resistors is so inefficient that it might as well be a war crime. Typical cheap buck converters are a couple $ a piece, and are typically 80-85% efficient (depending on the voltage and current).
"I didn't increase the speed. To stay street legal of course." 😂😂😂😂
You might also have been able to get more efficiency out of replacing the controller and thus increased range that way and you could have used a buck converter to bump the voltage down. if you put more battery on in series. A boost circuit might let him burn the battery lower than normal and get more speed.
@@Lunas2525 boost, not buck =)
The hell you talking about “bumping voltage up” is perfectly fine. You’re missing the part where he mentioned the buck converter - those only reduce voltage
@@signalworks if he wired the two packs in series a buck converter could be used to output 36v-72v he could set a range lets say 42v-36v above 44v i would imagine the motor would be getting hot if not hitting its limit they will suffer only so much over voltage. The other thing i was thinking rolling his own battery off 18650 it looked like there was almost room for 2 packs extending it by say 2 more banks of 6 cells to make it a 44v pack vs 36v.
To run the lights he just needed to run a voltage regulator that will drop the tail to 3v the headlight seemed to run at 4.5v imho better off stripping out for a 12v system. And a regulator to take 36-72v and put out 12v the head light and tail lights would output serious light then...
Careful! I fell off of one because of a tiny bump in the road when I had one hand on the handlebars. I wasn't even going that fast and it was bad. There's a reason these things aren't popular other than looks...
wait, did he just put a ton of resistors to lower the voltage? isn't that a waste of energy?
Keeps your nuts warm
I would have thought a couple of buck regulators would have been better (or one and then resistors for the lowest required voltage). $1 items from Aliexpress...
I think the leds are low current enough that the power loss is negligible
@@AL_O0 He said in another thread that the resistors use 4 W/hrs of the 154 W/hr battery. The lamps themselves probably only use a half of that at most. The current might be low but the voltage drop isn't.
@@AL_O0 Then why did he use so many resistors?
Me as a German when I saw the title:
He can't do that, this is a RECHTSWIDRIGKEIT!

The resistor set up is a very inelegant solution when all you need is a cheap little buck convertor.
Oh man! Right? He knows too why did you do that Scott! XD
Yea. On top of that, if the voltage drops, the light brightness will decrease too
He did say ‘price-related non-optimal’
Yes very inefficient too. Im surprised, hes normally good at this stuff.
How many watts do I need to dissipate= how many resistors I need to put in parallel seemed to be the main calculation here.
It is a simple and sufficient solution. A buck converter would have drawn standby current which would have drained the battery. The resistors waste around 4W of power which sounds like a lot but when you keep in mind that the scooter drains a 154Wh battery in an hour then the 4Wh for the resistors are pretty much irrelevant. But sure, you can use a buck converter if you want.
Hello. Thanks for sharing! For the "lights upgrade" - instead of dropping the voltage using resistors I would use step down converter - you had plenty of room for those and the advantage would be that once set - the lights would not dim when battery pack would discharge.
Sure but they draw a noticeable standby current and I wanted the battery to not drain through such loads when switch position 1 or 2 is active while the motor system is off.

GreatScott: What a nice brand new electric scooter. Let's tear it apart and upgrade it
He lives by the EEVBlog ideology. "Don't turn it on, take it apart!"
Lmao, i do the same with electronics
@@leiflang8097
Or Big Clive... Only this one isn't pink.
Maximum Speed Under a load is something to look into as well, like average speed under a small incline like 3 degrees or so, could be improved with a higher capacity battery pack but keep the voltage the same. This increases range and improves performance by reducing voltage drop on the motor. Did this to my E-scooter and went from 9 MPH up a slight incline to 11-12 MPH. Also gained 3 miles of range. Went from 5AH to 7AH. Also I have been losing weight which contributes to the scooter running more efficiently with less weight to carry.
Nice tip

@@joshua4302 yea :(
I just found out that all my 5 favorite UA-camrs are from Germany🤣
This type of videos always remain my best
I liked the two upgrades but the one on the lights with the couple dozen resistors looked, well, not very elegant :D. You can easily make a couple of crude constant current sources like those you have shown in so many of your videos...
Very creative way to add more energy capacity :3 I love it!
Great product, easy to clean -worked out great !
I'd rather use some small dc-dc to drive the lamps, to avoid wasting power on the resistors. Maybe i'd also put the lights in series to increase the overall required voltage (if they are rated similar voltage & current)
Modifications are a must with knolage, the more you know the more you mod! Love it.
🥃cheers🍻
Excellent mod vid!
Thanks for sharing!
Pretty awesome job, dude! Really nice! 😃
Brother u are genius!! Great idea,good planing and amazing skills!! Excelent work !!
His last statement was So inspiring and Energetic.
'stay creative and I will see you Next time'
Nice video, keep up the great work!
Surprised you gave up so easily on the max speed. I expected you to pull out a bigger BLDC from a lawn mower or something. Great video!
You could also keep the blades of the lawnmower, and just mow the grass aroudn the scooter as you go. And people's ankles.
@@RegahP that made me laugh
Yet another great video, thanks!!! Rock On!!!
Hi Greatscott thaks for that new video
Thanks for teachin us
This is awesome. Makes me want to get one of these scooters just to have a fun project to work on!
Very cool, it is now a E-Scotta ^^
The resistors were crazy!
Great video, as always. Thanks dude.
Every time he said scootaaa and powaaa i had to smile. I'm so sorry.
Really cool upgrade
Im surprised that you used a resistor to drop the voltage across the lights rather than use a buck converter. Was there a reason why?
Gotta luv this guy, does what we all think about but can't do for various reasons ✊🏿
Good video man, keep that way
Excellent video 👍
Great job Mr scott i think you are one of those persons without i can't learn anything about arduino and other electronic stuff.
You should have installed the resistors in the handlebar grips. Then you'd have the added bonus of hand warmers in wintertime ;)
🤣🤣
Haha true
Price related, optimal features. Sounds like fun.
I love the idea of using a serial port fir battery connection...
Your insurance might be invalid now :)
Yes it is, and it's also no street-legal anymore...
I don't know why, there aren't any modification regarding the legality. The things that must be present, OTOH, are: speed limit, power limit, front and back lights, two independent brakes, license number, bell. Unless there's a special clause in the insurance that forbids ANY modifications, it should still be street legal.
Only thing he did was add a jack for a second battery and hardwired the lights to run on the system battery and not a button cell and AA cells. They tend to run flat (no longer produce power) in usually 20/30 min depending on the outside temp, how often the lights are used (when riding at night) and how long they are "on" per trip. So technically he hasn't voided anything but the warranty. If something were to break on it, he couldn't send it back to be fixed.
@Ligius @Chris Lewis
As far as i understand this law here in germany: the scooters count as motor vehicle, same as for example cars. Because of that every scooter/product needs the official (TÜV) certification, number plate and insurance to be legal on public roads. The certification is invalid as soon as you modify any important part. It is not enough to have all features and that it works fine, there are chinese brand scooters that fulfill all technical requirements, but are still not street legal, just because the manufactures did not go through the certification process here.
Probably there are no special clauses from the insurance, but it is also void if they find out that the vehicle was not street legal... I would expect using external batteries counts as modified power train and could bring you in serious trouble.
In my opinion it is insane, especially with that low speed limit they should have just made it equal to bicycles, where all of this stuff is not required, even for E-Bikes up to 25km/h.
@@1Hippo a second battery has nothing to do with the power train because a battery is just a battery, you can change the battery in your car and not be in trouble. The power train is made up of the motor, gears/belts and tires. All that stuff he left as is. He did try another ESC to see if there is a difference in top speed but hooked the original one back up. As for the headlight and the tail light he hardwired them so he doesn't have to keep buying AAA batteries and button cells when they die... Soo to me it still sounds street legal.
Love your projects
This is the best video I have found on the inner nets...
Thanks for helping
from India
I Lived in Germany in the 80's for 3 years. I loved it. Was the cleanest place I ever lived. I remember folks getting out and sweeping the streets. I was relatively fluent speaking german, but forgot it all now. But in today's world? You couldn't pay me to live there. Back then i was able to own guns, go hunting and fishing... was pretty free. Now you can't do jack.
Much better to live in America instead. No amount of murdered children will change our minds about easy access to guns being more important than everything else in our lives.
Nice video mate 👍🏻
I think a video about your phone will be great in the future. Also i think your videos are great. Great job!😁
Modded it AND kept it street legal. Well done :)
Technically its not legal anymore because the scooter needs to be exactly like the spec sheet he had to use to get the insurance
Resistors? Check LM317 current limiter circuit configuration. You can do the exact same with a buck converter, i.e., make it a buck current controller.
Modified my e-scooter (Ninebot ES1) with 4 times as many batteries to get a much longer range. Requires two chargers, which I plan to replace with one beefier charger. The steering pole looks like it's been eating steroids with all the extra batteries hanging around. (Made some neat holders with help of a 3D printer).
I've also increased the maximum allowed current to the motor in the controller settings. A bit above the recommended settings for the BLDC motor. That did shorten the range a bit, but in turn, it got a lot stronger and have a much easier time uphill. I can always lower the speed to increase the range if need be.
The scooter in question is made from scrap-parts and broken/run over scooters I've bought from various sources, which made it all quite cheap.. except for the batteries. They're the most expensive parts in my case. I don't want to deal with batteries from questionable sources, or deal with "used" battery packs. One never know the state of those which can be dangerous.
Hey Scott, you should make a video on increasing the speed.
love your videos
You can also upgrade the speed by connecting your skateboard battery in series and using the VESC.
The rent scooters in my city (Santiago) get to 28Km/h, it's a little bit scary but a load of fun
I like that S10 battery percentage.. :)
Great ideas Great Scott...
Instead of using resistors to limit the current to the lights, would it not be more efficient to add a small buck regulator?
I love the electronic upgrades. I have a suggestion for the mechanical ones, LocTite Blue on all the screws & nuts used for the lights and reflectors. I'ts fairly inexpensive and works.
If range matters, just use a small DC-DC converter for the lights. They are much more efficient and will provide a constant voltage so your lights will not go dim when you accelerate or when the battery is low.
They cost less than €2 including shipping.
you should make some outside videos this spring and summer :)
If the motor has the torque to pull higher gearing, you can increase the top speed by putting a bigger tyre on it.
The speedo (if derived from the rear wheel rpm) will be inaccurate though.
Oh, and stick some grommets on the wires going through the metal to the battery, unless you want and "exciting" experience after it rubs through the insulation!
I have an electric longboard, and it’s really fun to ride it around where I live (but unfortunately I can’t take it out onto public roads because laws in my area haven’t caught up with technology)
I wear a reflective vest and have a red light on the back of the deck and on the back of my helmet, I also have a light on top of my helmet and a white light underneath the board.
Stay safe!
Nice upgrades you applied there!
I am interested in the same E-Scooter. How well does it handle going uphill?
Awesome. I am waiting for your videos weakly. Keep uploading. Another thing, i wanted to know every thing about switch mode power supply and feedback function.and 5l0380 ic.
very nice. It would be cool if you did a total beginner tutorial in exacty how an e-scooter works and what components to buy. I really want to design my own :D
@10:35 -"With a bit of loctite" he says, while putting what i use in a month on like 5000 bolts hehe x)
@desertrat810 I still love the guy, he makes great videos overall :)
Yay, Norway spotted in your geo tracker app in the video.
i made my own electric longboard for like 380€ and i love it, it's not the best because i'm not old so i don't have much money. It can go like 30kmph
Love this scooter!
I like the idea to combine the light power, should be more reliable and convenient. Btw Ebay has cheap DC-DC converters that would work perfectly for that. Such as the "Mini360 3A"
Love the video!
I like those Upgrades but why did you not use a buck converter for the front and back lights?
do you mean that your electric longboard etc cannot be used legally, not cool for diy and new technologies
yeah in germany at least.
Other countries may or may not have other regulations on that.
Theoretically electric skateboards are illigal on the streets,however thats not really enforced ^^
It's mainly for pedestrians safety to avoid something similar to what is happening recently in america where there are a lot of this scooters hitting people or causing problems
@@esepecesito not sure I get this joke 😂
Where I live (Spain) the maximun legal speed is 25km/h and like 600W of power for the motor. Btw, it is not so restricted, as I never had problems with my longboard that goes up to 40km/h and has a 2000W motor😂😂
Wait, is that a registration plate? ON A F*CKING ELECTRIC SCOOTER? WHAT KIND OF POLICE STATE IS THIS?!
Germany in a nutshell.
we germans like bureaucracy, I wouldn't call it a police state though
Netherlands requires you to have a driving license too
We neighbors (the netherlands) are not even allowed to ride on these scooters. I would love to own one to transport myself but it's simpely not allowed due to the fact that it's not an official 'vehicle' so it couldnt apply for an insurance.
@@roel_ some are allowed though, like a segway
God dam those resistance
that external dc port solved speed too u can just hookup higher voltage baterry ( be save dont use more than 20% increase)
Having seen yesterday‘s video makes 6:00 very funny. 😂✌️
Thanks Andi Scheuer!
beScheuert! 🤣
Amazing video scott, can you make a video about : 12v rechargable glue gun: diy or buy?
The mechanical problems related to vibration(bolts getting loose) can be remedied by using some loctite or equivalent product.
Too early on the comment I guess. Of course u thought of it.
Nice Video.
Wouldn't there be enough space for some small dc/dc-converters for your lights? The resistor-solution seems a bit crude.
Not crude. Simple and sufficient.
Your English is superb.
Well thank you😁
I recently bought one of these Megawheels scooters used from ebay for around 120 €. I didn't feel a need for a higher speed, but more power is needed. It has this 5.5 inch hub motor on it and I decided that without altering the original speed control at all, I'm just going to attach a decond similar motor on the front of it with its own speed controller. Now it should in theory have double the torque, but still the same speed of course costing the battery life, but in my use a smaller distance is really not a problem. I only need it for small bursts like 6 km after which I can plug it in to charge. Of course after this it wouldn't be legal in Germany anymore I think, because by my modifications it loses the kick detection and has way more power than legally allowed. In my country it's not a problem though, because no one really monitors these things and it doesn't need an insurance.
I have a s10e as well 😁 Best choice right now😁
I did something similar, I bought a very cheap one on gearbest for 170€ and I added Bluetooth and powr save breaking.
Creative with resistors! :P
Hey Scott,
so you bought a scooter without german street papers and you got them afterwards? was it worth it moneywise or did you spend so much that you could have bought one with papers in the beginning?
I've added a second battery in parralel on an m365, they have custom firrmware you can change the rpm limiter and current draw, got an extra 9mph becuase there is an extra bank of cells to draw curtrent from, little bit worried the mosfets will burn out though
The resistances in the circuit are atacched to the positive or the negative side of the lamp?
another way to overcome the top speed, which is often cheaper is to swap in a motor rated for slightly less voltage .. SO if this was a 36 v configuration , a 24 v motor of similar spec would make the top speed 27kph or so.. and the battery and controller could remain stock
Your insurance company would be proud:) good work though!
You could've added a photodiode for automatically turning the lights on and off whenever it's dark outside and an ESP for controlling certain features with your phone (power-saving mode, manually turning the lights on and off, etc.)
Might be a interesting project for an upcoming video!
Question,
1. Why not use a voltages regulator for the lamps to conserve power and compensate for the voltage drop for your battery as it discharges?
What is the maximum range after the range modification?
It would be interesting to see the differences
Awesome video as always. One question though, how can I calculate the resistance network for front and rear lamps? Any help will be appreciated. Thanks, Scott and community!
Seriously, dont use resistors, use a buck regulator
I was lucky enough that i found with a friend an elecric scooter in e-waste
It had its rear tire and rear disc brake damaged and batteries were really low
After repairs it was running like new and now comes the fun part
We are making some upgrades which are mainly: better torque(achieved by simply tinkering with controller), higher speed (getting a new sprocket for the rear wheel) and better range (getting a new set of batteries).
But we need to stay somewhat "legal" (atleast here in Slovakia) so there is an switch for slow mode and fast mode.
which model do you have?
i've been watching guys on yt with their modified e sur-ron bike's hitting 70mph.. that and this vid makes me want to get electric scooter/bike/bicycle
napr. :D íst 50kmh na kolobežke len v plavkách na domašu/širavu
Stay creative. I wiiiiill seeeee youuuu next time..😅😁👌
Is it possible to have a switch to change polarities of batteries when fast charging? For instant my battery pack is 36 v. But can I make a switch to change the polarities of battery with a flick of switch to 72v? Reason, to increase voltage so I can use higher v charger so my battery charge rate increase.
I have a dualtron X that i charge with solar energy. i love it to commute here in my region
DIY or BUY: Electric Scooter
Better buy an all terrain electric scooter, not those flimsy things
I doubt that he has the lathe, welder, foundry, forge, pipe bender and etc to take care of the mechanical aspect of such a project otherwise, it is a great suggestion
It will cost you less to buy it.
Well if you want to drive it on the street, you have to buy
@@zumbazumba1 i made myself e-scooter which is driving 25km/h it is combined from simple scooter and hoverboard. I bought used scooter for 40€ and broken hoverboard for 35€. With some other electronics from aliexpress price was under 100€.
10:05 Those resisters made me cringe hard.
yea its not the way i would have done it.. i would of used a DC to DC buck regulator.
Probably Great Scott hadn't any in stock and couldn't wait for it to arrive in time for the video
Or because of the issue with China right now and didn't want to take any chances...
