Just an update on these a few months later: our 3 year old is off the 125 and is now riding the mx350. We have had only had one maintenance issue on any of them. I was riding the mx650 (I weigh around 180 lbs) and doing some jumps the kids made. Hard landing broke the chain tensioner spring. Ordered one off of Amazon for a few bucks and it's a super easy repair. These bikes are some of the highest return on fun money we've purchased for our kids (with the only close competition being the trampoline). High, high recommendation. Just make sure you get the right size for your kid.

3 years old riding a 2 wheeler wow how things change 💯👍👍 this technology is awesome

thank you so much man for taking the time to do this video!!!

This was a GREAT MOMENT CAPTURED HERE !! Exactly how I want my daughters to look 11, 7 , an 6

Great review! Your video helps me decide what model to get my kids.

Thank you for spending the time to make this. It was very helpful. I am looking at one of these for my 7yo daughter.

The most helpful review I've found on these... thank you so much!

Thank you so much. As a single mom I’ve been so confused on which one would suit my 8 year old. After days of reading reviews you have helped more than anyone else.

Great video! Enjoyed it thoroughly! Keep up the good content!

Your video is just what I was looking for and so helpful, thank you very much! 🤙

Thank you soooo much for making this video it definitely helps on which one to buy. Thnx for taking the time again

Thank you for doing this video. Really helped us select the correct size.

Thank you for making this video! I actually have a 125 on lay-by for my boy who is turning 10.... I was going by the ages recommendation. Guess I will be going to cancel the lay-by now glad I saw this

You guys a great and lucky. Everyone look so happy together!

Thank you so much for this video you saved my life lol finding a good size for my 7 year old and 5 year old god bless your heart and happy holidays to you and your family

Thank you for this video. I was trying to compare the sizes. This video was perfect

I like how they all peeled off at 3:12!!!! The 3yr old seems like the leader for some reason! I like how he glanced over and surveyed the area before pulling off!!!! 😂😂😂😂😂

Love your review thank you so much that was the best way of explaining this. ❤

Thank you for taking the time to make this video!

THANK GOD FOR THIS VIDEO! sooo helpful!

great vid, thanks i was looking to get the 125 for a 6 year, but will now go for 350

Awesome video, thanks for making the choice easier!

Dude, thank you so much for making this video. I was having the same problem finding a good comparison video. Thank you thank you, you have a lovely family. Is there a big speed difference between the MX500 and MX650?

Great job dad and thank you for the great review.

Very helpful thanks for sharing 🤙🏼

needed this video... Thank You!

you guys are the best fam

Thanks for the comparison, size differences are impossible to figure out by online pictures alone. We just got our 3 year old the 125 and he absolutely loves it. I think he'll grow out of it within a year tho, no 7 year old I know would fit that thing.

Thank you for this video. I couldnt find a size guide

Exactly the video I was looking for to get my 4tear old on a bike.

Mate thank you so much for this video what a great idea

Thanks bro true Dad trying put smiles on dem kids lmao 🤣 love it good Dad points bro buying them for my kids too

I got my seven-year-old on a 48 V lithium SX 500 goes up to 28 miles an hour and my four-year-old on a MX 125 overvoltwd with a 20 V Dewalt battery but I’m thinking to put the 24 V motor in it as well so it drives better on grass. what do you think of the size difference between the 125 and the 350? I’m wondering if I should just get it 350 as well.

Thank you! Great video!

I remember having one of these at age 6 years old, now my 6 year old brother will get it for his b day

Needed this, thanks!!!!

Nice review. BTW, the SX500 has a different frame than the MX500 but same motor and controller. Supposedly beefier for jumps. I am 200 and also do ride the MX350 on the street. Works well.

Great reviewthanks!

Thank you! Looking at the green 500 for my son. He’s tall for 11 and 120#. Thanks for explaining the 500 and 650 are the same size, just wattage difference.

Aww, your beautiful family. Great review. I was about to get a 350 for my tall 9-year old, glad I saw this.

Thank you for this video!!

You are a legend. Thank you!

Thanks for the upload. I bought a 24v 200 watt bike for my son and I was affraid, that it is too slow, but after your video I thin my 17 kg son can get 12-15 mph with it and it is enough. He has now a two stroke speedbike, but it is too fast! I modified it so he can give just 1/3 or max 1/2 throttle, but it has still too much top speed! He drive quads too, but they have four wheels. The 500 watt quad or the 50 cc fourstroke in second gear with the regulater throttle is fine! Maybe a 50 cc fourstroke bike would be fine too.

Awesome video! Thanks

I was looking for this exact information with no luck until I found your video. Thank you for making this video and explaining the sizes! It was super helpful!

Needed this! THANK YOU!!!!!!!

beyond helpful! I have been racking my brain worried about getting the wrong size.... now I'm going to go with one of the 500s for my 9yeard old, seems like the best fit... how does your 9 year old feel about the speed? is it enough for him or does is leave him wanting something faster? Thanks for taking the time to make this video! its exactly what i needed to see!

Awesome video. Thank you.

I have a 3 year old about your son’s size at the time. How did he and the bike do with the mx350 off road? Mine will mostly be riding in dirt/grass and I’m thinking the 125 won’t have enough to get him around

Great video, not sure why I see thumbs down on these kind of videos.

Good review thanks 👍🏻

Thanks for the video. Got lots of kids and before we get into gas wanted some electric to learn off of. *yeah age guide they give is not "real world" guide lol Value mx 350 and SX500 are what I think are best.

Finally a helpful tutorial thing

I have been trying for a while now to see this razor should have done this for a commercial to show all of them at the same time

So helpful. Trying to figure out the best size for my 5 1/2 year old

Have your kids tried a stacyc bike? My 3 yr old loves the 12” but he’s outgrowing it and wants more power. 16” is a little quicker but not sure that I want to spend $1k on it

My son is five years old by 48 inches tall with a 20 inch inseam. Would he be tall enough to ride the Mx/sx500?

Hey Jeremy… do you think is possible ro transport the MX350 by plane,. Like in our luggage?

Very helpful well executed

GREAT vid mannn!! U R right, all othr vids DON'T show the difference btwn sizes, which keeps ya guess'n, which IS a bit frustrating 2 say the least!! THNX 4 sharin', now I KNW wht size 2 get 4 my nephew who is 2 yrs old & wants a REAL motorcycle tht will take him farther faster than his power wheels bikes & balance bikes

Omg thank you I was going off their age guides and almost got the 125 for my 8 year old he would have been so disappointed lol

Hey Jeremy, I’m looking into getting the MX 350, however I read that the battery time is only around 30 minutes and then it takes over four hours to charge… Are you able to buy a second battery to pop inside it once the first one dies so my little guy can keep riding?

Nice! How do you start your 3 year old to be able to ride

Great vid

Hey mate, I have ordered the 350 for my kid, he’s 4 1/2, I’ve heard that the brake lever on the 350 can be a bit of a task for younger kids to grip. I was going to order the MX125 brake lever if its any smaller? Can you confirm if they are the same size for me? Cheers.

Do the 500’s have variable throttle speed? Meaning if you twist the throttle is it either on or off. Or will it go slower the less you turn it and faster the farther you turn it?

do the sx500’s come with rear suspension?

thanks brother.

My son has the MX350, his front tire keeps going low, have you found any better tubes to replace it with? I found actual parts from them to replace but didn’t know if it would be better than a tube from Walmart or somewhere similar.

I’m on the fence between the 350 or 500. My daughter is turning 7 and is about 4’ tall. If I’m reading correctly the speed is the same between those two? Don’t want the 500 to be too big size wise and her not be able to ride it.

OMG TY! 💓

Does anyone know if the mx650 is legal for Australia?

Can you do a speed test on the mx650 please

Thanks you helped alot 😊

Could you please make a video on the difference in power. Thank you very much! 🤙

Can you show them on a hill climb?

super helpfull video

Sweet thanks bro

I just got my 5 year old the MX400 and my 3 year old MX350 it's a tad to big for him right now but I got him that red electric razor drift trike he loves it untill he fits that MX maybe in the next 6 months 👍

Do you think my 8 year old son can handle the mx500 I was thinking the mx350 was to small

Damn as a 13 year old I’ve been wanting one of these for a long time now

Thanks

Size comparison of bikes with kids whoes sizes are unknown to viewers is an huge oversight, in my opinion. So girl on mx650 is 5 foot ? Age and heights are not always a constant ratio as u may know. Just like models of bikes listed, plz list the kids height as well, which will make this review useful.

how tall are all these kids

Do the two smaller bikes have adjustable throttle speed?

Trying to decide between the 500 and 650 for my 10 year old daughter. Is the 650 worth the extra money over the 500?

The MX650 is for me and there is also a RSF650 it’s like the MX650 but a tiny bit faster

Hell yeah my 6yo is on the MX650

They sound like Tie-fighters!

Hello there, I would like you to tell me the height of the kids in the video instead of the age

4:14 the kid on the red mx500 about went over the handlebars😅

Man had 4 kids and bought 5 dirt bikes to show people a 5 minute video about them

Perfect review. They should pay you for this

What about the rsf650 ?

Price?

Thank you thank you thank you every one of your kids had at least some kind of a helmet on I been involved in Jr mx worked with kids and I've seen kid haveing their life destroyed is destroyed over not having a helmet ON

wish I would hv seen this video before I bought mine

I am 11 so ima get the mx650 for Christmas cause i know how to ride the easiers one and i want to try the best one.

Just wait for when their older and want to start modding them

I am getting sx 500
