eBike Kit: 48V 1800W Razor Quad ATV Upgrade Father/Son Project! - Part 1

[@SteveHartmanVideos]

This was great thank you… I learned more from watching your mistakes than from watching someone doing it right.

[@TonyStone31]

I freaking love Daves commentary! We didn't expect perfect welds from a genius programmer! ;)

[@johnnybravo-jj8uw]

Love your honesty...I hate when people bashes someone's work when they are only trying to help others. You did a great job.

[@neogator26]

Love it! "I don't know exactly what I'm doing but I'm smart enough to learn and I'll record it for you to watch!". This is pretty much what I hope my channel to be when I graduate and have time to launch it.

[@DavesGarage]

One thing I didn't mention in the video is that the reason for moving the motor forward was that once I had it apart and counted the teeth and the transmission to compute the final ratio, the driven sprocket on the axle needed to be so large (70+ teeth) that it interfered with the "stock" mounting location, hence the need to move it in front of the spring.

[@hjw5774]

Thanks for this update! Did you find that the motor had enough torque when under load? I'm thinking of using it to convert a mobility scooter.

[@davidjessee7701]

Did you know you can buy a half link?

[@brianbellerive8546]

Nice clean job, there's nothing I can appreciate more than a project such as this done the right way. Thanks for sharing!

[@chandrairugalbandara7087]

Guy who made the task manager for windows uses a Mac 😂. Love the videos ❤️🔥

[@CaesarCapone]

This is a great video! I'm surprised to see only 260 subscribers. Dave's clearly very knowledgeable, and I look forward to checking out his other videos.

[@DavesGarage]

Thanks for the kind words! Just starting out, so not sure how to gain subs others than more videos, so that's what I'm doing...

[@CaesarCapone]

@@DavesGarage Glad to hear you're just starting! The mismatch between quality and subscribers makes sense. Best wishes!

[@liammeyer]

Very knowledgeable is an understatement... This guy did in fact code that lovely task manager inside of windows... And a whole bunch of other things!

[@CaesarCapone]

@@liammeyer Really? Wow!!!

[@MikkoKorkalo]

Just in case you didn't figure out the phase wiring yet: AFAIK you need to reverse blue & yellow phase wires, and green & yellow hall sensor wires. I'm on the same boat, but I have the 60V 2000W BLDC version.

[@veritasvalere88]

Good job welding Dave

[@idubz]

Deserves ALOT more views

[@DavesGarage]

Thanks! It's slowly starting to get them!

[@digitizebrands]

Great detailed video looking forward for part 2

[@gulfwarvet9895]

You’re hilarious and pretty darn good at fabricating on the fly! I have an old Razor dirt quad that my son outgrew. I may add this upgrade as a Michigan winter project:-) Thank you, I enjoyed the video:-)

[@LongHoang-tb9zw]

I enjoyed the narration. 🎉

[@DescartesRenegade]

Just switch 2 phase wires and pull the hall sensors. Also, for as much fabrication as you've done, add a chain tensioner.

[@rxbejar]

Cool vid, good luck with the rest of it. I also love you stereo system

[@mvretriever]

Is there a part 2 video for the completion of the upgrade? Thank you for part 1. My son and I are starting the same upgrade.

[@pbpaulieb]

No because this guy really doesn't know what he's doing. Don't follow the advice on this video lol

[@edmuller6268]

Great video. You have a great sense of humor, and had me laughing during several parts of the video..

[@CPTDilxDozer]

Cant wait to see these test run!!

[@santiagoaraujo3202]

Cool video. Enjoyed watching the trial and error part which youtubers sometimes try to hide. Would be really cool to see a before and after test of the quad riding up to the mailbox once and back compared to the new set up.

[@DavesGarage]

Thanks! I was wondering if showing mistakes was a good idea, but I learn from them, so others might too! In the final installation I plan to "drag race" it agains an original, unmodified example. Since we have two and have only modified one I'll be able to do a number of comparisons!

[@santiagoaraujo3202]

@@DavesGarage Awesome! Excited to see the final product. Good luck on the comparisons.

[@duane617]

Lived up to expectations!

[@SRTDave707]

👍🏾 all I need is a big garage like that 😂

[@mmmasterscross7915]

Thanks for sharing this video

[@denverdantheman853]

I love how you show it wasn’t a perfect build. All the oopsies.

[@chuloooph]

His kids doesn’t know that his dad is a hero, he made the manhattan project equivalent in windows - task manager. Not to mention a souped up quad bike. Lucky !

[@brookeplum6565]

we know he’s a hero !!

[@Asher_Noel2012]

Love your channel

[@tenazrael]

Awesome video. I'm planning on upgrading my kids quad as well and these videos are going to be very helpful! In your part two video, would you be willing to share with us the parts you purchased (motor, controller, battery) upgrade and used? Thank you again for making this vid. Can't wait for part 2.

[@georgetomkoiv282]

Is there a part 2 to this video yet?

[@krispi707]

Great upgrade... Trying win brats back... without breaking the wallet!

[@plojm123]

No part 2? We are all on our feet lol

[@peewee7405]

Why didn't you just make the motor mounting holes elongated so that you could adjust the chain tension ? Simple easy. You could have used a lock nut on the motor instead of nut zerts. Too much overthinking the process.

[@NanaNan1]

I think we have the 24 volt version. I’ve seen a video where they increased to 36 volts by using Ryobi power tool batteries and another where they added a 3rd 12v battery like the stock batteries. Any suggestions on the most straightforward way to modify the smaller 24v Razor? Thanks

[@ari1234.]

What lithium battery you had on it at first?

[@edgarh252]

Nice Garage.

[@mgiles5507]

U need to add a tensioner to the chain to allow for stretching

[@Adam_of_strength]

rear suspension under pressure will smash the motor

[@bananapants9140]

love the video!

[@DaDon145]

Great video. Just out of curiosity what's that gorgeous watch you are wearing?

[@AllThingsAudioHTX]

Rolex

[@markadams4423]

It’s a brushless motor so change the three main wires, it’s basically a 3 phase motor

[@Catamount19]

Hello Dave, do you have a video showing the battery replacement?

[@jefferycundiff3804]

Was it just the lithium batteries that fried the old setup?

[@Infernight88]

Is there a part 2 to this

[@lufuifisofojefedafa2976]

Hey Dave quick question my electric qoad stopped working the forward dont work only the reverse what can I do to fix this issue

[@NeasYellek]

Great video. Would like to see finished product being ridden. Also parts list and where you got it would help us to build similar. How much did the parts cost for this upgrade?

[@veritasvalere88]

Because if it breaks and it gets complicated and you want to get parts you can always get parts from factory setting versus here you have to customize everything

[@Bennysnamehere]

I was trying to replace my Electric ATV's 1500w 48v (4x12v20Ah lead acid) battery and I was wondering what LiFeP04 battery you could recommend to replace my old acid battery. Any help would be greatly appreciated.

[@WildPowerSports]

Dave, you dont need a new controller. You wired it wrong. Brushless motors can run either direction, you just need to get the phase wires and halls in the correct order. With a job like this, call a pro...like us, Wild Scooter Parts. We have built many brushless setups up to 30,000 watt.

[@manuelsalgado8510]

How did you fix the grinding noise on the quad 500?

[@CB-ug6xh]

Can you let me know where you bought the controller that had reverse built in?

[@DavesGarage]

eBay! I wish there was a part number, but I just found it one day, and there are normally several available.

[@kdaodfjaokjfaodf4493]

where is part 2? Need a simpler, non frame cutting and welding version. Can you show the wiring in detail showing which wire is connected to which from the throttle to controller, and the motor?

[@stephenvonvoros5405]

here it is: www.ebay.com/itm/Razor-Quad-500-Performance-Kit-48v-Performance-Kit-FAST-Controller-and-Throttle/324027749466

[@richfortin08]

😳 my 2 year olds driving the stock razor quad right now lol wtf am I gonna do when he’s 10!

[@veritasvalere88]

Could’ve done the suspension mount welded to the previous suspension mouth since the previous suspension Mount was better or a factory welded

[@kalyddessalines769]

Where did you get the 48v battery from?

[@leviray5935]

Where did you get the new controller I’m having the same promblem also where did you get the chain guard

[@DavesGarage]

Controller is from Amazon (and eBay), but the chain guard had to be fabricated.

[@leviray5935]

Dave's Garage can you put a link pls and did it help you make your motor go foward

[@stephenvonvoros5405]

To change the motor rotation reverse the terminals inside of the connector (easy fix)

[@leviray5935]

Stephen von Voros wich connectors and how is there a way I can contact u

[@leviray5935]

Nvm I’m think what I’m doing is going to probably work I’m gonna swap my brake and sprocket sides and that will give my atv access to go foward

[@veritasvalere88]

I would’ve kept the original set up and Compensate for space elsewhere but I would’ve kept the original set of factory settings

[@daniel2000dn]

You can just flip one of the motor wires and it will rotate right

[@scottloutner5253]

Just add a spring loadedchain tensioner.

[@scottbob3917]

Hello where is part 2

Do you know the speed 😅?

Still great though my first go cart was simply to dolly linked into one another... Then it was a wooden one

[@jeffreytabor9278]

come on man... part 2

[@JRJRCrawlers]

I know I'm like where is Part 2

[@stephenvonvoros5405]

@@JRJRCrawlers, Yeah I would like to see part 2 as well. To change the motor rotation reverse the terminals inside of the connector (easy fix) I have since bought my own Dirt Quad 500 and upgraded the 3 batteries to 10Ah, added a key switch and reverse through an additional relay. The 10 mph stock speed is OK for my back yard. The 48 volt mod in this post seems unnecessary any more speed or power would just make the front spindles break quicker! IMO

[@JRJRCrawlers]

Stephen von Voros yeah my sons we upgraded and stretched and it’s about 14 top speed after some gearing changes too...

[@stephenvonvoros5405]

@@JRJRCrawlers Thanks for the reply, I would think the ebay 48 volt upgrade kit would be a simpler method

[@JRJRCrawlers]

Stephen von Voros actually this was a lot simpler and cost effective and we only added one battery... My sons is the Dirt Quad not the 500

[@jcssg391]

Whats parts information?

[@brayray709]

When is part 2 ?

[@DavesGarage]

Just added the "final" piece, I think - a chain tensioner to keep the chain from jumping, and should be able to do part 2 soon!

After all this why not just throw a small gas motor on it? Would’ve been way cheaper and about the same amount of work.
