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!

> 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).
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. th-cam.com/video/snaJxB_psg8/w-d-xo.html
@@NiHaoMike64 He's not paralleling the batteries. He's switching from one to the other (SPDT power switch).
"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...

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.
It was posted right now! How did you post your comment a week ago
?

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.
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?

@Alex McRae shit is like crack dude
Awesome! Really functional upgrades. Great work. 🤜🏼🤛🏼
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

Hi Greatscott thaks for that new video
Thanks for teachin us
Modifications are a must with knolage, the more you know the more you mod! Love it.
🥃cheers🍻
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...
Excellent video 👍
Really cool upgrade
This is awesome. Makes me want to get one of these scooters just to have a fun project to work on!
Yet another great video, thanks!!! Rock On!!!
Good video man, keep that way
Great video, as always. Thanks dude.
Very cool, it is now a E-Scotta ^^
His last statement was So inspiring and Energetic.
'stay creative and I will see you Next time'
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.
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)
Great job Mr scott i think you are one of those persons without i can't learn anything about arduino and other electronic stuff.
Will you ever make a collab with electroboom in one video? :D
Maybe someday....

Gotta luv this guy, does what we all think about but can't do for various reasons ✊🏿
Every time he said scootaaa and powaaa i had to smile. I'm so sorry.
love your videos
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.
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
Price related, optimal features. Sounds like fun.
you should make some outside videos this spring and summer :)
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.
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
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.
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!
This is the best video I have found on the inner nets...
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.
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!
The resistors were crazy!
You should have installed the resistors in the handlebar grips. Then you'd have the added bonus of hand warmers in wintertime ;)
🤣🤣
Haha true
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
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!
Yay, Norway spotted in your geo tracker app in the video.
Love this scooter!
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
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.
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.
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.
Nice upgrades you applied there!
I am interested in the same E-Scooter. How well does it handle going uphill?
You can also upgrade the speed by connecting your skateboard battery in series and using the VESC.
I love the idea of using a serial port fir battery connection...
I like that S10 battery percentage.. :)
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?
Thanks for helping
from India
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
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
Having seen yesterday‘s video makes 6:00 very funny. 😂✌️
I did something similar, I bought a very cheap one on gearbest for 170€ and I added Bluetooth and powr save breaking.
You should start a series called 'Buy.... and modify?' where you just buy the cheapest of a product and make it good, and then compare it to buying something like the final product, or maybe you could incorporate it into DIY or buy? Good stuff regardless
I bought that scooter after Xmas for $99 us. It's a great scooter!
I liked your video as always but I was disappointed you didn't manner it faster!
Manner = make?
Man, I'm sorry to hear that Germany has such scooter laws.
If I were you, I would have bought a Xiaomi M365 though, even if it isn't technically street legal (would people really notice?). It probably has larger tires (8.5 inches, which you can upgrade to 10 with little modifications), has a higher range, and a top speed of 15 mph, or 24 km/h, which can be easily increased with a custom firmware up to 35 km/h.
They would notice - the scooters require a license plate.
Yeah, i don't get why he even bought a street legal model if he wanted to modify it anyway.
Creative with resistors! :P
I got the street-legal Doc Green ESA 5000 from Lidl in Germany for 300 Euro on Black Friday last year. It does not require batteries for the lights, the range is 22km, the motor is 350W and the bigger battery helps to maintain 20km/h even with a small charge left. The other good thing is that the chassis is an exact copy of the M365 and a lot of accessories are cheaply available from China. It is not perfect tho, the battery indicator is not connected to the BMS and thus is a simple voltage display that does not work well with the voltage sag that the scooter experiences under load and also does not have suspension nor pneumatic tires. There is another version that is basically identical, it is called ESA 1919 and you can currently buy it for around 350 Euro and I still think it's worth the 70 EUR over the Maginon Street One.
that external dc port solved speed too u can just hookup higher voltage baterry ( be save dont use more than 20% increase)
@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 :)
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?
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!
Hey Scott, you should make a video on increasing the speed.
super cool
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?
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
The resistances in the circuit are atacched to the positive or the negative side of the lamp?
Great Scott: "Drives by with a tunes scooter"
Police man: "Drops his donut and looks amazed with open mouth"
I hope my state makes escooters legal soon. I've got 2 Razor E300 scooters I was given. Both need batteries and one needs a controller, but not much point doing all that if I can't do anything with them afterwards.
Hammer Video ✌ den ESA 5000 (den es für 300€ bei Lidl gab) kann man auch super upgraden.
Mich überrascht, dass du 12km geschafft hast. Freunde von mir schaffen nur um die 5-6km 😅
Great scoot!
Your insurance company would be proud:) good work though!
I have a s10e as well 😁 Best choice right now😁
Good content, excellent editing, really enjoyed your video - thank you from Canada! Now you need to make us an electric snow mobile!
I have a dualtron X that i charge with solar energy. i love it to commute here in my region
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.
Always thumbs up
The rent scooters in my city (Santiago) get to 28Km/h, it's a little bit scary but a load of fun
For the same price you could have get an used e-twow booster S2 with an impressive motor that could could have driven to insane speeds (just for in lab use obviously). But maybe it is more of a C.Furze kind of mod. The e-twow are known for having tons of hacks already existing : upgraded controlers, external battery backs, disc brakes... And they are even cheap clones of the e-Twow with the same great motors if you preffer brand new items.
I like those Upgrades but why did you not use a buck converter for the front and back lights?
Haha, I boost e-scooter speed by using cheap 4€ buck converter to step up voltage (versus new battery 200€). Theoretically it could go up to 45km/h but since controller limits motor rotation speed, it can't go faster than 30km/h. But still improvement on 20km/h (with 36v battery). It may sound like stupid idea, but I have tried it and now I can't help but to use it everyday since 10km/h is quite improvement on speed and I can use it as charger too. Even though buck converter has 96% efficiency and speed has increased, I haven't noticed any significant difference in total mileage that it can go with single charge.
Great video, I'm hoping to get a ev of some type. I don't know about a scooter that small, I'd like a small E- motorcycle, don't know if they are lefal here, something like the "pit bikes" only electric, with atleast 1500 watt motor, 5kw would be better. At about 72-96v I live in a small town, kinda backwards thinking kinda place, who knows what they will allow, converting a 125cc trail bike to street E- bike, with about 3kw motor, with the lights, bells and whistles! Great video
