How To Mod A Razor Crazy Cart! 

Absolutely insane how fast that goes

What an amazing guy. Thanks for being so organized you even included a spreadsheet

bro got me into something i didn’t know existed, my area probably sucks for em but i have a few spots in mind thanks for this info my g

This dude knows his stuff

I recently immigrated to a south Portuguese small town neighbourhood, where everyone knows each other, except me (I don’t even know the language yet). Just moving here already shook up the neighbourhood, I feel like whipping one of those around the block without being able to explain it to the (mostly) senior citizens due to the language barrier would definitely be the cherry on top.

So expensive! I did not expect this to be that much of a set up

As a former competitive downhill Longboarder, I recognized those Orangatang Durian wheels immediately!! I dont mean to be a huge snobby nerd in the comments but maybe someone will find some interest in additional information about longboard wheels. They can have a really significant change in the ride characteristics of these carts, as they did in my longboarding "career" (it was a hobby when i was 18-22 but i took it very seriously lol) For context, lets remember some specs about the Durians here; they are 75mm tall with a Width of 52mm and contact patch of 45mm 3 Topics; Durometer, Bearing Seat Position, Lip Shape. > Durometer: Longboard/ Streetboard wheels are made from Polyurethane. The unit for measuring the hardness of polyurethane is called Durometer. The yellow Orangatang Durians pictured here have a durometer of "86a" which is on the upper end of hardness for a longboard wheel. Street/ Park boards (the usual double kick boards) are very hard, usually floating around 101a or more. As he says at 5:04 & 11:00 the cart has no suspension AND its metal on metal. Which means you're going to feel every crack and rock that you roll over. When i was racing at events like Maryhill Festival of Speed, I would usually setup my boards to have a higher duro in the front and lower duro in the rear of the same wheel (Something like 82a / 76a [speed up front, grip in the back]). A Lower duro = softer wheel. Softer wheel = smoother ride as it can absorb more shock and roll over cracks alot easier. Harder wheels were usually the bane of me falling flat on my face while going up a curb or hitting a rock. With that being said, harder wheels will keep their speed in straights, but that's not applicable here as you have a dedicated motor and arent reliant on the same variables such as aerodynamics as in long board racing which is a Gravity sport. *So look into the Orange 80a Orangatang Durians as a side grade replacement for this cart. A nice balance between speed and absorption that'll run you about $65 > Bearing Seat Position: There are 3 positions for the "Hub" in which the bearing sits on; Centerset, Offset & Sideset. This is important due to wear patterns and grip characteristics. A Sideset wheel is going to be much more susceptible to "coning" vs a Centerset wheel as on a standard 10.5 inch wide longboard, the weight is focused more on the inside of the wheel. This is great for power sliding and "Free-Riding" (taking the concept of friction created by the spinning wheel and using that to stop by throwing the board sideways) but wears super quickly resulting in buying another set of wheel (usually $50 for a set). Sector 9 Butterballs and Abec 11 Flashbacks were notorious for this. Personally, i was a big fan of center set wheels as they lasted a long time. Whenever they would begin to "cone" too much on one side, just rotate them and wear the otherside. They were really great for technical downhill where i needed to have additional agility and control over the wheels to get around tight corners. I was running Centeset Abec 11 Grippins (70mm - 81a) back then for technical downhill and Offset Venom Cannibals (76mm - 76a) for high speed downhill (50+mph) the Grippins would fit on those casters no problem. 52mm wide with a larger 50mm contact patch. > Lip Shape: Probably not applicable to a Crazy Cart but worth mentioning anyways. The discussion between Round vs Square Lip shape was important to me as Racer because i was looking for a "square" lipped wheel. Reason being; when taking a corner, a square lip will fold under and dig into the pavement as opposed to a Round lip which has less resistance, resulting in sliding and potentially washing out/ crashing. You might not be able to find a Square Lipped, centerset wheel - at least not one that would fit these casters.. so the runner up to that is a Rounded lip with as little of a bevel as possible. That's why i recommend something like the Grippins. You can get a better idea of all of this information from these 2 old school videos: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-g2DZl-repP8.html x ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HKwM-akPpe0.html As far as the Loaded bearings he talks about at 19:01 you can definitely keep them you dont need anything overkill like Bones Swiss Ceramics or any bullshit like that. I used to just run $10 Rush bearings and treat them like disposable batteries; when they rust or dry out, toss them out hah. Edit: if you’re planning on riding on wet roads (keyword; planning), what we used to do was mill lines around our wheels with a dremmel or lathe for better traction just like a tire. Call them rain wheels. TLDR: You could probably swap out those Yellow 86a Orangatang Durian Wheels with a softer variant like the Orange 80a offerings from them OR Abec 11's Grippins in 78a and get a smoother ride with better traction and more even wear pattern for a longer life span.

the Duracell case is amazing I'm absolutely gonna do that

Mark my word your going to go viral

Well damn, i know what i want for Christmas 😂

The price on those castors nearly gave me a heart attack 🤯

"THE CRAZOR 2.0" LOOKS SAVAGE FUN!😄

Thanks for this video been looking for parts and this explains everything!

Hey bro I don’t even know how to check messages so I might not see it but basically if I wanted to get into this I should by the cheap (500$) 24v starter one instead of the 1k xl one, and rather put extra 500$ I would’ve spent on the the xl into making the regular one way fast/quality of life. So give or take not including labor I would cost 1k more or less to have the setup you run. Also thank you for making this vid, albeit this is an “expensive hobby” it’s nothing in cost compared drifting real cars. I’d rather go all out spent 1k for me and my girl to get into this hobby and something fun for us to do together

Thank you man ima need one of these

the link for the brushless motor kit doesn’t work

Great video, just bought the stage 4.5 from taxi garage cant wait

If you can, can you please upload a video of you setting the motor, esc and battery up?

Hey man, you made me really interested about getting one of these lol. Are there any other decent castors/casters whatever they are called? 260 is kinda insane for me, too much for my country xd

Pot holes and big O notches on the sidewalks must be brutal 😂

This looks like a ton of fun

Hi someone please answer this :) For the second recommended setup, when u said 48v battery w/ speed controller. Can I use those with the stock motor ? Also on taxi garage the 48v battery doesn’t come with a speed controller can I also use the stock speed controller? Thanks

Need to build one with/change that battery out to a 72V!

Super useful video! You should include timestamps in the future for those looking for specific mods ect.

So he basically bought a crazy cart and then built another one lmao all jokes aside this is awesome good job 👏

What do you recommend for a beginner motor that will be running on 36V battery and 36V speed controller

The Crazy Cart King

How much would you charge for one of those carts?

Found you of insta.. great video and explanation 🙏🏻👌🏻

you got me looking into new hobby now :D

Im willing to pay this guy to make me one !

Can you post the video on how to install battery and everything else? i buy everything. I just don't want to mess up 😅

I think I found a new hobby!

im planning to do a budget brushless build from chargedup3d and a Amorge Customizable Battery Pack 48V 16AH 60AMP battery, where do i get a speed controller for my build? or will the budget brushless kid will already come with a speed controller.

How did you connect the 38v controller to the standard Crazy Cart? It doesn't look like the wires for the on/off switch come directly out of the 38v controller like they do for the 24v controller. I bought the 38v controller and can't figure it out

Can i ask ya why haven't you gone to the chassis. What are the difference in body alone looks like you got the drift bar from xl steering wheel ect ect ? Im looking at buying one but just wondering

I wanted to ask where else I can buy such a battery, because Amazon can not send to Switzerland. I find nothing online. and can you buy such a lever as you have somewhere?

Have you tried s hub motor? Guessing theres not enough space?

Is this your standard size razor crazy car? Or is it the xl?

Well shiz... I just wanna put a XL motor on the ST cart... But I don't know if that's possible. BTW Do you have a tutorial on the handbrake? Cool stuff!!!

please tell me if u know what's a app to test ur speed and see how fast ur going

I put a 52v hub motor on mine from a broken scooter i had and a 52v controller and the battery from the scooter too lol it does 36mph

All I have to buy a razer XL and crazy kart mod kit then I’m good To go!

Also for the absolutely necessary upgrades, is it just a motor, ESC and battery?

Do you have the link to the tires? Thanks!

Is this based off the xl crazy cart or the smaller one?

Hey man, I was just wondering, with the speedo. Is it always going to be set to miles? Or can it easily be changed to Kilometers.

Does your friend with the black cart that’s kinda caged have a tutorial on their build as well?

Hey! Do you know when the brushless motor will be available again? Cuz it’s out of stock right now

How long did it take bro to type/ have time to think about this

What about your cart makes it go above 30? I was thinking the 48volt setup but I want to be able to haul on straight aways

Could you like add lights to it and what kinda light would you recommend

Are you going to put them in stores for kids to buy? Cuz I don't see how to make them I don't see myself ever taken the time to put them together so are you going to make them and sell them or what?

Can you make a vid of how to install them into the crazy cart

Does it matter how many amp the battery have or not?

is the 1000w speed controller fine for the xl motor

Will u build some of These and Sell it?

Where did you buy the xl steering wheel? 😊

How much would you put one of these together for? And any way to make it more comfortable for a tall rider?

im a fairly large-ish guy, any reason to get the XL over the basic one?

hello!, im just asking if the bateries fit onto the crazy cart stock motors

are these the XL carts?? swear i have 2 and mine look way smaller

Can you show me how you do the handbrake?

Is this xl or just the regular one? What’s the difference or recommendation?

is your drift bar a former pop can crusher?

I just got a cart and that battery adapter dose not look like it would fit in the one it comes with

Cant believe Taxi Garage charges that much for the castors... i found them at my local castor shop for $36 might not be the same wheel but even getting longboard wheels would not jump it up to $400

what is the name and brand of that battery?

So I have 4 stage 4 900w 48v battery setup with my Crazy Carts from Taxigarage.. would these mods make my carts faster? I am liking the Mph speed reading mod and the battery reader mods.

Where did you buy the xl steering wheel?

I want one so bad for Christmas where can I buy one ?😂

Is it the extra large or the kids size

hey so when you buy a battery and a speed controller how do i know if the connectors match eachother. like the ones u linked they dont have the yellow connector like you have on your cart. pls lmk

Hey I bought ur set up you have linked for the 500w motor and it isn’t working I was wondering if you could help me

What are the specs of the motor you have on it?

Is this the standard razor crazy cart?

Is that a XL or standard size ?

I am not an electrician but couldn't you just put a step down transformer coming off the main battery to power the speedometer?

hello pluto i have a question when im doing the 48v setup do i have to buy a different/bigger chain or is the one on the normal one good?

For the headset bearing on your 500watt crazy cart, are those the bearing that come with the crazy cart xl or are they upgraded?

I’m around 6’2 would I be able to ride one of these? Looks so fun

Blud basically mad an amped up xl

Brushless motor kit page 'not found'! 😢

Will these upgrades work on xl?

How did u make the Duracell battery cover

Wait till the baby fw11 comes out from sotion. It fits this frame and has a 3k rating

Can u run the stock battrry with the 500w motor and 36v speed controllers

What charger do you use?

I want to know about the speed pedal

Would an 800 watt motor work?

wheres the amazon two pack front tire link

Can you make a video comparing different types of Tires? Knobby, Fat Tire Mod, Solid Tire Also a video with different caster wheels and what effects they have on riding style

So 48v and 15ah is transacted to a controller that a 48v and 900w? Is that how it works?

Can you send info on your drift bar setup?

INCREDIBLE

Why did you link a XL speed controller for a Standard Kart? Is it still compatible?

Where did you get your stock cart

When I try to click the link for amorge battery’s it says the connection isn’t safe

Should I get a normal cart or an xl? Im 6 foot btw

I love this idea and would like to get a fleat of them to come on rides with me along side of my dnb bike ❤🎉😊
