How To Mod A Razor Crazy Cart! 

Absolutely insane how fast that goes

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

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.

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.

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

This dude knows his stuff

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

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

"THE CRAZOR 2.0" LOOKS SAVAGE FUN!😄

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

Thank you man ima need one of these

This looks like a ton of fun

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

Mark my word your going to go viral

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

Well damn, i know what i want for Christmas 😂

The Crazy Cart King

Coolio! Thanks for the info :)

INCREDIBLE

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

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

the link for the brushless motor kit doesn’t work

Im willing to pay this guy to make me one !

That is awesome

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

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

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

I think I found a new hobby!

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

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?

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

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

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

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 ❤🎉😊

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

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

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

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

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

Thanks so much my cart goes like 20mph now

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.

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

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

Will these upgrades work on xl?

How did u make the Duracell battery cover

Can you send info on your drift bar setup?

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

Question how do u recharge it ?

can the 500w motor from the xl fit in the standard?

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

Where did you buy the xl steering wheel? 😊

What charger do you use?

Where did you get your stock cart

Where did you buy the xl steering wheel?

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

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

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

How much would you charge for one of those carts?

Will u build some of These and Sell it?

is your drift bar a former pop can crusher?

Does any 36V motor work?

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

Well, maybe I'll have a new project this summer....

Can we get links for the drift bar plss

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

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

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

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

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

Yoga mat material on the hard seat

What crazy cart do I buy?

Does your chain ever fall off?

What model is this?

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?

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

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

Brushless motor kit page 'not found'! 😢

Is it just better to start with the xl cart and go from there especially for an adult I'm not sure how much larger it is versus the regular carts

What kind of cart is it

Is this the xl crazy cart?

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.

does it matter if its the 500$ or 1000$

HOW MUCH DOES IT COST I WANT TO BUY THIS CART

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

How much would u sell it for?

There are no brakes??

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

wheres the amazon two pack front tire link

How much is your cart in total?

Crazy carts usually cost around $500

What size cart do you use and how tall are you? 🤔

Do i need a license for it or something cause im a kid

I can’t find the battery

5:04 glad i have many years experience w da SHIT w my car w/o any goddamn suspension breh

I want one of these so bad but I’ve got no money for ine

Is that the xl crazy cart or the regular one??

id love to do this it’s just all the things that are linked are saying they’re unavailable 😭💔

You should stretch it

So hypothetically can one of these pull off a Texas turnaround?
