I actually really like how you did all the theoretical math for the gear ratios and engine speed ect.
+Nicklous Walker thanks! It meant this episode took longer to make but I really wanted to put in a proper explanation so people could follow why the bigger motor didn't make the scooter faster straight away. :D
Standing here in my garage, looking at our two modded e300's and listening to my Boy TK go through his own Scooter Journey again for what feels like the 50th time. Thank you my friend for all the inspiration.
Glad you enjoy the vids, sounds like you're having fun out there :D
@@WhatUpTKHere You're a little too big for that scooter. you need a bigger scooter
In all razor scooters there is already an extension for the air pressure valve in the right handle ;)
🤣🤣🤣
I did the same thing then found the extension after I got the tires aired up 😂😂
YEEEEESSSSS!!!! I have been waiting forever for this
+BGT Productions maaaaayte :D
TK I have watched this whole project come tohether I juat wanted to say good job I learned alot. p.s I subbed
Thanks for these videos.
Glad you're enjoying them! More to come, as ever. :D
TK please reply to my other comment.
Inside the right handle there is an extention for the air pressure valve
Great bunch of videos mate. I did almost the exact same thing with my Razor
Thanks! Modding these things is rad, hey.
Yeh kinda.. Once you get past a certain point you get a lot of broken chains and trying to actually ride one of these at plus 40mph is a bowel loosening experience. I used a 1000w, 36v, 3000rpm motor powered buy three 11v, 8000mah lipos...it power wheelied like a crosser lol
love all your scooter mod vids! More!!!!
I bought a brand new Razor E300 yesterday. After half year or more I will make a little project and make it faster, maybe tune it !
btw Awesome video dude !
Adomas Studio thanks :D enjoy your scooter!
TK Hey dude, great video. Where did you get the years from?Jim looking for the same.
TK Always love being ignored 👍
Wow, this looks like crazy good times. I have to laugh at the pure joy of it all.
I am waiting for my E300 to arrive and then will follow your videos to up - f&cking-grade the pedestrian stock scooter. Will you ever take a spin with night vision goggles?
Thanks for terrific series of videos.
As in, would I try and ride while wearing night vision goggles? That'd be awesome.
As for filming in night vision, I lack the equipment.
I'd love a proper night vision scope to muck around with though.
This guy taught me math in the most interesting way I subbed
Cheers homie!
You are one funny dude lol ..."because you just connot win in this world " 😂 you said it
nice finish
+Dickie Withers thanks! Really was awesome fun to film :)
I have a tiny ball end on my pump that I attached to a length of hose after the pump's lever, allows me to pressuring my razor, and mongoose miniscoot just fine. Give it a try man!
Great idea, will do!
It's a Success!
I assume you'd want the tensioner on the bottom of the chain because you'd want uninterrupted tension on the top. Tension on the top is pulling to rotate the wheel while the bottom its pushing the chain towards the rear wheel
Yeah I getcha!
Great series so far! Building up one myself. I weigh 215 or about 98kg though . My Son 62lbs or 28kgs. I can get going about 10mph after a stretch and he gets up to 15mph. Bought a variable speed controlled and bumping it to the 500w Motor to start. Can't wait to get it bolted together. Debating buying a second E300..
Nice! They’re great fun to ride in pairs, to be honest
My boy is 50 lbs and he can hit 17-18 mph on a full charge. He's got the taller balloon tires on his though. 2 12V 9Ah AGM batteries and a variable throttle.
Thanks for the Videos TK! Do you have links to all the products used (starting from the electrical components in the early episodes)? I'm hoping to follow this upgrade!
Jivan Purutyan there are links in the description :)
You should get a variable throttle so it’s not putting as much strain on your motor that would also keep the temp down
Great advice, makes it more rideable
Great work. you should make an ebay package and sell it with all the bits needed to do your mod.
Thanks!
It'd be pretty impossible to make any money doing that, particularly as there's a certain skill level required to bodge the better MOSFETs into the original controller. It's also not really the easiest, quickest way to make a fast scooter - just the way I wanted to do it. There are some upgrade kits out there already for E300s which do offer folks varying levels of success.
Damm bro I’m just getting into the wave I’m definitely gonna mod mine😂💯
Rock it! 🔥
I got a razor e300s brand new last December and I have bearly used it due to the fact I can't go full throttle in my area. where I am can only go around 5 miles and hour but I've saw you can get a variable speed throttle so I plan on getting one of these and hopefully I get more battery out of it because instead of having to go on and off the throttle to keep it around 5mhp I will be able to just hold it around that speed with the new throttle and therfor i think I'll get more battery life. What do you think?
Nice.
I wish I could do this or buy it from you it looks amazingly fun and I could use it for so many things!!!!
Ihaveadiamond follow your dreams ;D thanks for watching!
follow my dreams sorry I dont think I can my soldering iron is way too weak and I dont have nearly as much experience I just make flashlights for fun I dont think I can make a scooter mod a fraction of the power or speed which is a shame
Did anyone else notice the WD-40 helping the "burnout" at the end?
Old Hollywood trick :D
Wow wow wow wow and wow, did I forget to say WOW?
Thanks for watching!
wow that is so fast scooter
Thanks!

I'm doing something similar with my old Mierda Powercycle 500, an electric assisted bicycle, having a hard time locating the original motor controller box since it's such a special controller, but something I may suggest is using a 19 tooth sprocket, it's what my bike manual suggests to get Max speed with the lame 250 watt motor ;) just an idea I'd pass on to a fellow electric nut ;)
Hello KT,
My 800W evo scooter goes 25 kmph.
On the site stays that it koes 35kmph.
How can i upgrade the gearing?
What is the standart nm?
What teeth does work on the gearing upgrade?
I would like a replay,
Regards. Tycho
good videos assume your warranty is void lol whats the battery life ??
hi TK awesome razor !! i wanna feel that power too hehehe
were can i buy a 15t pinion??? thanks
Check out Ali Baba!
Great videos...I’m gonna try to do this, to my X-Treme X-360 electric scooter...wish me luck.
Give it a go!
Thanks... I definitely will.
How do you get your hands on different sprockets so easily? I have a nightmare of a time finding the right sprocket with the right bore etc.
QuentinQuark Alibaba and attention to detail :)
Nice Miata
Thanks pal!
i had the same problem with not pumpingthe tires until a found it in the right side compartment attached to the plug
i hope this helps you
+Carl Marold it does! Thanks, I totally forgot it was there!
I know this is an old video... but would you ever consider going with a hub brushless motor?
Thinking of going brushless inrunner actually?
Very interesting comical video
Thanks for watching ;D
That looks like Adelaide in the thebarton area?
hey dude im doing my razor up and wonderd if u got a link or list of were u got your upgrades anyhelp be sweet nick
Thanks :)
Will the bigger motor decrease the time that you can ride
sweet miata
Orgnolf hairy-legs thanks! Track day vid to come ;D
haha sweet!
Great job. But what I did with mine was replaced the motor sprocket with a 13t and the same time replaced the rear plate sprocket with a 15% smaller one ( came from a shopping cart scooter and modified the holes to fit the Razor). The result was crazy fast, it's scary
That's awesome. These things are so sketchy at high speed but that's what makes it fun.
TK.
I just upgraded the e300 to 36 volts. New controller, a new battery, so now there is three batteries.
New throttle. Which would be faster, the original motor, or a 500 watt motor?
Please let me know and thank you.
Kenny
Hi Kenny, well, it depends if you choose a 500W motor that also has a higher RPM/Volt rating than the stock one.
I made the mistake of choosing a more powerful motor, but one that turned slower at 36V than the stock one. This meant I had to muck around changing gears.
I suggest checking out my video on photo tachometers, and then using one to measure the no-load RPM of your current motor on 36V. Then you can shop around to see if you can find a higher power motor that also runs at the right speed.
Can be tricky! You can always consider changing gearing, too, of course.
czcams.com/video/QVSQLfnKytk/video.html
So how long does the battery last? Enough to play around with it in front of the house or can you actually go to the store or ride it to school and back? Is it still just a toy? Good video!
Thanks! This setup had about 5-8 km of range, to answer your question :)
Imagine how much fun a minimoto gp bike would be, around 20-25kg 6,5inch wheels
Would be pretty cool!
the chain tentioner
Yep, backwards hahaha
Hi where did you buy your 15 tooth sprocket please
Hi what scooter is easy to put on a gas 2 stroke motor without too much cutting or welding? Can you recommend a base scooter to buy that I can slap on a motor and chain will fit in back tire sprocket?
Hm very hard to say! E300 is chain driven but will require lots of work I suspect.
10mm doesn't fit the stock motor behind the sprocket? Also it's round so none of the spanner sizes do?
Ah, frustrating. Sometimes they have flats you can get a spanner on
Hey TK, idk if anyone posted this already or if you know, but the extension for inflating the rear tire can be found in the right handlebar grip.
Aaron Amberson hahaha, dude thank you!
Yeah no prob. I have my own scooter, the e300"s", which just means that the seat came with it. I hope that the axle isn't bent, but the rear tire seems to make a wavy noise when it's running. What do you think it is? I guess it could be the brake...
Aaron Amberson hm, not sure what you mean by a wavy noise, but I get a shuffling sound from the brake regularly because the band brake has a very flexible frame and the band often rubs.
Ok thanks. I'll try adjusting the brake, but it does seem that the axle IS actually bent. It's either that or razor did a dandy job of centering the sprocket. Is there a way to bend the axle back? no clue how it got bent.
no real decent way of bending the axle back straight. you'd want a new part.
can be bent quite easily through bumps or dropping off kerbs, depending on how thick the axle is versus the weight of the rider.
I had this problem often with my earlier scooter builds due to being an adult riding a scooter spec'd for children.
The chain tensioner should be on the slack side not the power or pull side. (Bottom of chain pushing up)
Yep!
So NOW....how long (minutes), does the battery last, before you have to recharge them? How far in miles, can you ride the scooter now?
This revision had a 5-6 km range. As per my latest video, I’ve blown the thing up trying to upgrade this - stay tuned!
Okay batteries are at 21 + V reset button continuity good power switch button continuity good accelerator switch continuities good brake pedal however if it doesn't do like you said what function does it have against the relay if any and will it stop everything?
21V is low, suggests the batteries are dead
did it not come with a pump adaptor in the right handle bar grip end? I didnt realise i had one hidden in there for ages lol
ha! thanks, that helps a lot.
now my tires are harder!
@@WhatUpTKHere haha hope all is well is it back on the road brother?
I want to mod my razor e100 glow, you are awesome man! thanks for the lessons
No probs homie, good luck with the build :)
Spoiler alert !🤯there is a extension for pumping the tire built inside your handle bar grips 😊
Hahaha that’s where it is!
The tensioner has to touch on the bottom on the outside of the chain and what batteries are you using
V and ah?
If you watch the earlier vids, I swap over to 2 x 7 Ah 5S lipos for a nominal voltage of 36 V.
@@WhatUpTKHere
My bad didn't watch that video before
I'm not an expert or anything but I hav an e300 too and one time I just doubled up the batteries from 2 scooters with pretty bad run time I'm talking about 10 to 20 min instead of 45min
I ran them parallel 24v and 14 ah wich would be more like 10 ah or so everything else stock
My smaler brother maybe 130lb went 29kmh on it and it would run over 1 h
So my bet is you don't have enough amps
Most of the heat is comming from that double diode. The same current that passes through your MOSFET also passes through these diodes. I am actually surprised they hold up so well. Give it a somewhat more generous diode and the temps should go down quit significantly
+hylacemess I'm not sure I follow - those diodes I believe are snubber diodes which are there to block spikes from the motor's back EMF, so there shouldn't be any major current flow through it?
The way this controller is build is most likely as follows: Motor is connected to battery + and MOSFET drain. MOSFET source is connected to battery -. By twisting the throttle the controler starts switching the MOSFET on for short amounts of time. During these time slots current starts to flow through both motor and MOSFET. The slope however is not infinitly steap. Instead it ramps up with a rate which is proportional to the inductance of the motor (it is a big coil in the end). Remember: Inductors resisit current changes. This is key to understand what the diode is for. It is connected antiparallel to the Motor. That means it is in reverse direction so that in motor resting state it does not conduct. Otherwise it would short out the motor. As the MOSFET is now switched off the current in the motor is not able to instandly go back to zero. Just like before it slowly ramps down. Only this time the current can not go through the MOSFET as it is turned off. That is when the diode starts conducting. The motor current over time looks like triangles joind end to end. The rising slope is going through the MOSFET and the falling one is going through the Diode. So the average current through MOSFET and diode are the same.
+hylacemess ah yes, I see. I can confirm the circuit is set up in that way.
I may spec a better diode; when you say "more generous", what precisely do you mean?
Do you have any reliable estimate of the motor current? As I am pretty sure the answer is no, "more generouse" means exaclty that ;) The original diode handles about 30A continuous (by the way 45v max, so thats pretty close, too). Finding a diode in a package that fits in your controler might proofe challenging. Also doubling up on them might be your only choice.
Something like a MBR60H100 should do the trick.
There's 2 wire at the brake cut the one that's closest to the handle bar as close to brakes as you can get it's makes it fast but idk why it does
Very interesting, I may have to investigate
my tensioners spring broke is there any way to fix it or make the chain tighter ?
Could just get a new spring?
Got a uber scooter 1000w what do u jeep to max it out on the speed I am new at this game please show me :)
A new motor and speed controller and battery is one way to go :) happy scooting!
So did you have to change the motor? Could you have just changed the gearing??
I changed to a bigger motor because I burned up the original one.
How many chain links did u end up with?
Oh no idea, maybe you can freeze-frame and count
Make more episodes of the razor let’s go channel/blog
Mitchell Malek I can promise there will be some very cool electric vehicle stuff in the coming year. We're gonna branch out - the E300 isn't the only game in town!
Time for a bigger scooter
Bigger can be gooder!
you have the chain on the wrong side of it
it has to loop under it then over the sprocket
+
Ahaha yeah, I still get comments on this daily!
There no indication of continuity what do I do to replace the brake indicator?
Hm, I think the brake switch is in the lever
Just spotted from your speed calculations that you are running on 9" wheels. Consider switching to 10". It will fit with the new motor (since it does for me and I have the same setup). You'll get a bit more ground clearance (I'm not complaining on bumpy corners) and a bit better ride and handling.
Yeah, I'm running whatever came on the scooter. If there's an easy 10" upgrade it could be cool.
Just try to check if bigger tire would fit your rim. I can take some measurements of my rim if you'd like. My scooter was factory equipped with 3.00-4, 10" tires. Might not sound like that big of a difference, but just looking on your ground clearance it is way smaller. I have totally no problem when cornering. Try to check if this was only the tire that was changing depenging on region/version, or if also rim might be different.
Also planning to put a disk brake for the rear tire. Just returned from a ~6km ride and while I am not concerned with drive and electronics (the motor is only a little bit warm) I feel that the scooter brakes way worse after getting hot. I already have on the way some stuff from aliexpress to convert it to disc brake. Will see how much rework will be necessary to fit it in.
Any chance you can measure your tyre circumference and get back to me? I was pretty sure I was running 10 inchers already haha.
Thanks for the tip on controllers by the way. I might have to scope out a good 36V one as I would like to try variable throttle.
The circumference of my wheel is around 800mm, that's why I noticed when you were calculating yours (I was already using it to install a simple bike computer with speed indicator). You can see a difference with a bare eye. I'll try to get you some photos. I would ask guys from electricscooterparts if there's a different size of rim for 9 and 10 inch wheels for razor. If it's the same - you can just purchase new tubes and tires.
I'm still waiting for parts for disc brake, since the simple drum brake gets quite hot after ~6km ride from work and I can feel how braking is affected (when the drum is hot it basically cannot convert more energy into heat).
Also thinking of making the handlebar a bit wider. Might make it a bit more stable on tight corners and bumpy pavements. Maybe just cut the original one and weld a mounting for bicycle handlebar? Who knows...maybe then I would be more comfortable with a bit more toque when starting and I would remove the 25A limit :D
What battery are u powering e300s
i ordered a 24v 500w motor. Making a custom scooter already made the sprocket for the wheels
DieEneBelg ik heb een evo 800w electric scooter gekocht hij gaat 2
30 kmph. Hij heeft een 11t tandwiel standaart ik heb net een 15t tandwiel bij ali gekocht. Hopelijk gaat hij 35 - 40 kmph
Tycho Eghuizen Ik hoop het voor jou ook! Ik heb ook veel spullen gekocht vab ali zoals knoppen en controllers enz
DieEneBelg nice ik ben 12 xd
ItsTycho ik ook.
DieEneBelg maak een vid van je step
Did not you try what voltage can hold 24 v motor?
Yeah they don't love 36V!
@@WhatUpTKHere thanks
View month ago removed original petrol engine, and welded adapter so can use Razor scooter 12v motor, and 24v Razor controller and throttle handle. Powered from dyson hover 25.2v motor, was working, but not enough power when get to grass curring. Revs going down. Yesterday rebuilt it, to razor 24v motor and razor throttle handle, chinise 36v brushed controller, hoverboard 36v battery. Now power enough, but if go near at full throttle too long, motor build up heat, so for home use it is good enough, if let cool down. Need to make some sort of case to hide battery and controller
Did you work it out with the load ( you )
Can’t really use the phototach while I’m riding but it got up to a good speed, I think 35-37 in this episode?
what educational background do you come from? I'm sure its engineering related. what is your job, as well? thanks mate
jerhms Mech/Aero eng, though all my electronics knowledge is self taught. ;D
do you have any idea of the range on the scooter
Don't have a great idea, as I ride it more for fun than anything. I find electric scooters are too "interesting" to make useful transport - I wouldn't be comfortable leaving it locked up outside anywhere because someone would mess with it.
I know it'll go further then 3km. Probably 5-10.
Where did you buy the gear at??
Colin Joseph took some careful searching on Alibaba.
In my experiance with close to the same setup, I'd say you are over gearing it. The motor is getting hot because it's not turning enough rpm. I think you'd get closer to your target with a lower gear.
Avtually in a later episode I go faster with even higher gearing - and then later blow it all up XD
Your chain tensioner is installed WRONG! It must be on the botom chain (chain return to the motor) and lifting up, What you have is on the torque side lifting up which dose nothing but try to lift chain against the FULL torque of the motor. Put it on right and the chain can be looser reduceing drag and binding while the tensioner keeps the chain from flopping. This might get you over 40kph. Hope thid helps.
Yeah, we noted and fixed that a while back hahaha. Thanks for the tip. More work to come.
are you from melbourne?
I move around Australia a fair bit, actually!
What is that speedometer app?
Ulysses Speedometer Pro on Android, kicks butt :)
I have a working stock ES300. Can anyone recommend an upgrade kit? Thanks!
Try eBay "E300 overvolt"
Distance ?
About 6km. More to come on that front in a new video ;D

At -9:43 you just can't win in this world😂. I would say You just have to go with the flow to win.
True enough!
i have an old razor pocket mod scooter my plan is to put a weed eater engine in it
i might go with a 75cc predator engine from harbor freight instead those motors get decent speeds
That's cool! The one thing you wanna think about is making sure you have some sort of clutch mechanism.
it would be easy to find a clutch for the 75cc but for the weed eater engine it would be hard to find a clutch
Donovan Bryant ah yep, makes sense. Would love to do something with a small engine down the track myself!
Can you tell me the range? I won't to do a project like yours, my only stress is "how to have the range that I need"
I haven't actually done a ride until it dies but it should be better than stock I reckon!
Can you tell me an idea...
Bruno Mendes dunno! 5 k? 10? somewhere in between?
GO RAIDERS
jorgescar69 HELL YEAH!
How does it go up hills?
Pretty damn well. Even the Ryobi drill batteries from Episode 2 made a good difference in this respect. Stock it was woeful.
Are you calculating your weight?
I can hardly recall, perhaps?
I have the cheapest electric scooter from razor and I have direct power from batteries to motor it goes fast after modification
gearing won't increase much if you don't increase battery voltage or controller amps.
Wait and see ;D
totally awesome series. I'm revamping my Schwinn S180 that was already fitted with a Currie 24v 500w motor overvolted at 36v, 15T pinion and 65T rear sprockets. Topped out at 33+ mph with me on it at 195-200lbs. It gets pretty warm, so I'm going to regear at 15/55, drop it back to 24V but using 4 12v batteries in a series parallel config to increase range.
The YK31c controller has the shunt mod and has held up thus far, but I'm a little worried about current draw with the new gearing and less voltage. Should I get a rolling start before throttling to prevent huge current spikes? Also, that diode thing you were talking about below.... could going higher value there decrease my controller temps?
Diode is just for snubbing the back EMF, so shouldn't need to change.
Definitely riding it easy should help, but it can be tough to ride soft to protect a controller. See how you go!
DiCarlo Thompson this is my homemade e bike. Can do 31 mph, but with prehistoric brakes it is scary to say the least,
czcams.com/video/pol2SoZokkk/video.html
Almost 33 mph
Almost!
How long would the battery life last on a run?
Thus far untested, but I should have data later this week.

I want to fit 2x 180w 2500rpm 24v brush motors to my sons regular bicycle. The Motors were given to me . I have access to machine shop and welding equipment. So the mechanical side will be easy . I would like links where i can purchase components. Eg speed controllers and variable throttle controller . I have no wiring @ all to go on - so it will be guess and go. I am familiar with some electronics . there's a warehouse near by that does mosfet s and a ton of other bits. . I,m keen on a simple throttle concept 36v . I may need some of your amazing info. Gearing i can sort out easy enough.
Type in "brushed speed controller 24V" to eBay and you should be good. You can get a 250W or 500W controller that should have plenty of overhead to safely run your motor
Then ask the seller to include or suggest a throttle that suits
100😂💪🤘
