[@kimgilpin5103]

Please consider helping me one of those could literally change my life

[@dvdv8197]

Hi, just wondering, if I do in fact notice a very slight bend (makes a faint noise when it passes a certain point when I let the wheel turn while cleaning my scooter), is it important to fix it straight away to prevent further damage, or is it not that much of a problem and I can just let it be as it is if I don't feel comfortable doing the repair you suggested? 🧐🤷‍♀️ Thanks in advance for your reply! :-)

[@dontplay3088]

My boys back wheel is rubbing on his pure e scooter. Do you think it could be this bent brake issue.

[@JesseOBrien]

This helped so much! I hit my disc brake on a curb and it was dragging really badly. Used the marker trick and slowly bent it back out. Amazing!

[@ESG-ElectricScooterGuide]

Glad it was helpful! Thanks for watching & stay safe. -Vosk

[@kyleanthony1903]

This saved me a lot of aggravation with my Apollo Phantom v2. Thanks for posting this!

[@ESG-ElectricScooterGuide]

Np! Thanks for watching -Vosk

[@velocity441]

I'd like to see a series on fixing common failure points on popular models

[@RupakShakur]

This video has been beyond helpful. Thank you so much!

[@ESG-ElectricScooterGuide]

I’m so happy to hear it! Thanks for letting me know! -Paul

[@hydrazi]

Thank you. I hit a pothole in Ecuador on my electric moped. This video helped me fix it myself! Much appreciated.

[@metallurgico]

Great video! You should consider talking about stem and fork damage as I think are the other common issues with scooters

[@xabstractx]

Thank you so much!! I got my new scooter today and it came with a bent rotor, this video got me up and running 😊

[@ESG-ElectricScooterGuide]

Nice! That's exactly how I figured out that they were straightenable! I pulled a really nice scooter out of the box with really bent rotors and didn't want to wait for replacement parts!!! -Paul

[@ChrumkavySuchar]

Nice, simple, short video, explaining everything. Thank you

[@ESG-ElectricScooterGuide]

Happy to help! -Paul

[@gokhaninal]

Thank you very much. This is what I was looking for hours :)

[@ESG-ElectricScooterGuide]

So happy to help! -Paul

[@mikeashland1901]

Just did this on my new Vsett 10+. Rotors were out 3mm on the rear & 1mm front as delivered (shipping movement). Your technique flattened the rear in 3 goes & the front in 1. Nutt brakes are silent, smooth & strong. Thanks!

[@ESG-ElectricScooterGuide]

Awesome! The worst rotor damage I've ever seen was straight out of the box! Thankfully that one was a prototype, so they just hadn't worked out the best packing material for it. I gave the manufacturer feedback on that so they could improve the packing for production. -Paul

[@you6312]

Great thank you. Have this problem on my daughter’s scooter. Going to try this method

[@anttmann6123]

Great vid Paul I hope this becomes a regular series on the channel.

[@ESG-ElectricScooterGuide]

Thanks so much! We already have a few more in the works and will keep doing it if we can. There is so much content we want to produce! It's hard to pick what videos to make! -Paul

[@newbornsound]

Thank you for the video! Also, I dig the accent light in the back of your video

[@ESG-ElectricScooterGuide]

Thank you! I tried shooting the first one on my phone and our AV pros weren't having it! Richie and Ramier make everything look so good! -Paul

[@513west4]

Totally fixed my issue. Had a brand new scooter and it rubbed. Thank you!!

[@ESG-ElectricScooterGuide]

Great to hear!

[@888anvil]

Thank you again, another really well presented and informative tutorial

[@ESG-ElectricScooterGuide]

Glad you enjoyed it!

[@googleuser7126]

Yes more content like this!

[@ESG-ElectricScooterGuide]

Thanks so much! -Paul

[@RonSiemons]

would love see the replacement for a beter brake rotor on the Inokim oxo, thanks your videos are the best!

[@AnthonyLamberson-re1gf]

Thank you so much it help me out

[@usernamef3125]

Great, help me a lot

[@ESG-ElectricScooterGuide]

Glad it helped!

[@Camrographer]

That's a good tip especially due to the lack of peripheral protection of small diameter of the wheels. I've bent my rotor simply by placing my folded scooter inside my car and it fell over an leaned on the rotors. maybe I can figure some kind of attachment to protect them when traveling.

[@ESG-ElectricScooterGuide]

I'd like to see thicker rotors on all scooters. The Wolf King has 3mm thick rotors and not only do they resist bending better than other rotors, the peak temperature they hit during sporty braking isn't as high, so braking feels more consistent. -Paul

[@Simcore999]

Lucky for me the lithium-patriot uses a front foot braking system with a rear fender disconnect, the rescue-markv12 also uses a front pad braking system so no rotor to align

[@izralizuddin1674]

I want to see tyre changes, brake cable replacement and motor replacement. Please do that. Your video is very easy to understand and it helps me a lot. Love your video❤

[@ESG-ElectricScooterGuide]

Thanhs so much!

[@bigzybinc]

Hi. Will you only hear something is wrong while riding? Because I’m getting like a knocking sound coming from the wheel or disk when riding but on a work bench, you do not hear anything it looks and sounds normal.

[@ESG-ElectricScooterGuide]

Yes while riding

[@tom-uy2uc]

Would that give you a front wheel wobble if going at higher speed? If rotor rubs?

[@ESG-ElectricScooterGuide]

Unless it's happening when you apply the brakes I don't think a rotor is the cause. More likely you have a tire that's not fully seated on the wheel, possibly a tire that's just not that round to begin with, or a tire that's out of balance. I've been able to balance scooter wheels using motorcycle weights, but it's pretty hard to do on a wheel that has a motor, since you need the wheel to spin freely to find the light spot. -Paul

[@chrishall3008]

Maybe some tips on how to remove a rounded out screw and bolt, I seem to be having a problem with that on my zero10x, I have the right tools, good quality too, so any help on this would be appreciated 👍🛠️

[@ESG-ElectricScooterGuide]

Great idea! Thank you. I'll try to sneak this into the upcoming Loc-Tite video. -Paul

[@chrishall3008]

@@ESG-ElectricScooterGuide cool, thank you!

[@Dinco422]

Aren't you contaminating the disk with the marker ? And pads as well ?

[@ESG-ElectricScooterGuide]

It wipes off easily with brake cleaner or alcohol. Even if you don't wipe it off, it doesn't really affect the pads or rotor, since it's not a lubricant. Another way to go is that most rotors are going to have a space at the inner or outer edge where there is no pad contact at all. -Paul

[@Dinco422]

@@ESG-ElectricScooterGuide I see, gotcha!

[@anttmann6123]

Hey Paul did you see the new three wheeled Gotrax? Sorry if I'm asking in the wrong place.

[@ESG-ElectricScooterGuide]

Ask anywhere! Yes, I just saw it on their website last week, but haven't ridden one yet. Very surprising move for them! -Paul

[@anttmann6123]

@@ESG-ElectricScooterGuide Yeah definitely surprising. They're claiming better stability? Those rear tires look a little to close together to be touting increased stability but we'll see. I saw a fellow train operator at work with a Cycleboard. Now that looked interesting.

[@jaybarker1239]

Does this cause a grinding type of noise when turning/leaning?

[@ESG-ElectricScooterGuide]

It might!

[@af_gucci6750]

Sow its ok if it sounds a little bit?

[@ESG-ElectricScooterGuide]

Yes. Totally ok to hear a little drag as long as it's not slowing the wheel down much. -Paul

[@MexicanAndy]

You should do a tutorial with a hydraulic brake fluid

[@ESG-ElectricScooterGuide]

Definitely! I need to study a little more before I do that one. I've had some good results here with our scooters, but I want to make sure I can do it in a comprehensive way. Thank you! -Paul

[@youtube-user73424]

👍🏻

[@lancomedic]

Is there a chance of breaking the rotor?

[@ESG-ElectricScooterGuide]

Hi Fred, Steel is really good about bending, and being able to bend back without fracturing. It would take a severe, absolutely unstraightenable bend to cause it to crack when bent back. -Paul

[@lancomedic]

@@ESG-ElectricScooterGuide Thanks

[@CMedia87]

How do you fix squeaky breaks when breaking?

[@ESG-ElectricScooterGuide]

Often times straightening the rotor and aligning the brake caliper takes care of this. When that fails, a little brake cleaner on the rotors can help. Cleaning the pads can help, but that's a lot harder. In extreme cases, changing to different pads can help too. -Paul

[@CMedia87]

@@ESG-ElectricScooterGuide thank you

[@bkkorner]

I have this problem. The scooter is only 5 days old. It should not be doing this. It scrapes when going backwards. It runs great otherwise. Help!

[@ESG-ElectricScooterGuide]

Try to follow the tutorial!

[@GenZyannd]

Paul, let's a slime tires

[@ESG-ElectricScooterGuide]

Yessssss! We need to slime tires. And Armor-Dilloz them too! That will be a messy day once I start punching holes -Paul

[@kimgilpin5103]

Hi my name is mat I only got 800$ and need a way to see my son's is there any way you could help me get like a used fast scooter please consider trying to help me. Keep up good work love the videos.

[@sierc.android]

Wheel wobble front and rear

[@ESG-ElectricScooterGuide]

Is it something you feel only at high speed, or at all speeds? Which scooter? I've had some luck balancing wheels with wheel weights, but it's a lot harder on a scooter than a motorcycle. -Paul

[@stakzfn84]

My wheel dosent even move because the break thing is bent

[@ESG-ElectricScooterGuide]

As soon as I get my hands on one, I'll test it :-) -Paul
