2 Pcs Kids Ride on Car Gearbox 550 12V Motor 30000RPM, Motorcycles High Speed RS550 Drive Engine Match Specific Children Ride on Toys

Bought these to replace the motors on my kid's 12V ride-on Lamborghini. The gearbox on my kid's car started making loud grinding sounds after years of use so I found these on Amazon and it fixed their car. I also converted their ride-on to use 20V drill batteries so the increased voltage combined with these new motors made the car double in speed. That's one quick ride-on Lambo

I recently purchased the 2 Pcs Kids Ride On Car Gearbox 550 12V Motor 300 for my child's Grave Digger ride-on car. Unfortunately, I encountered some issues as the motors did not fit properly.The motors are specifically designed for 12V ride-on cars and are supposed to be compatible with various models, including the Grave Digger. However, upon receiving the motors, I noticed that they were slightly larger than the original motors in my child's ride-on car. This made it impossible for me to install them properly.I attempted to make adjustments and modifications to the ride-on car in order to accommodate the larger motors, but unfortunately, my efforts were unsuccessful. The size difference was too significant, and there was no way to securely attach the new motors without jeopardizing the safety and functionality of the vehicle.I was disappointed with this purchase because I was hoping to upgrade the performance of my child's ride-on car with these new motors. However, due to the compatibility issues, I was unable to do so.I reached out to the seller to discuss the problem, and they were responsive and offered a refund. While I appreciate their customer service, I am still disappointed that the motors did not fit as expected.In summary, if you are considering purchasing the 2 Pcs Kids Ride On Car Gearbox 550 12V Motor 300 for your Grave Digger ride-on car or a similar model, I would advise you to double-check the compatibility and dimensions before making the purchase. It's always important to ensure that the parts you buy are a perfect fit for your specific vehicle to avoid any potential issues or inconveniences.

I purchased these to replace a burned out motor in my son's 12v tractor, which I purchased on Amazon last year (2022). I didn't realize they would be such an upgrade! My 4yo son loves the upgraded speed on his tractor! If I had known about these as an option, I would have upgraded awhile ago.I was previously thinking about upgrading to 18v or 24v, but we definitely don't need that at this point.Installation was super easy and the gearboxes fit without any issue. We have only had them for a week, so I can't give a statement on their longevity. Very satisfied so far!

Do not get these, not worth the money. Work for a few seconds and then they stop

These work well on flat ground but the second my son wanted to go up a small hill they didn't have the power. his stock motors were 15000rpm and had no issues on hills but these can't make it up the slightest incline.

I replaced a set of 35k gears and motors with this set. The slight loss in speed seems to be un noticed. It is a balancing act with speed and torque. We have hilly terrain here so I wanted it to stall less, and hear less whining, lolThe machine is set up with dual 12v 500w esc, one going to each motor with independent sets of F/R relays.

Let me start by saying that you have to reverse the wiring on one motor so they dont go opposite directions. Super easy fix, but with that being said.. Dads and handy Moms... get the battery adapter for your little ones ride that fits the batteries for whatever power tools you use. I bought a Dewalt adapter and use my 20v batteries. I did this with the stock motors and saw an immediate boost in speed even with those. I got these motors as a replacement because my daughters were going out and let me tell ya... that thing friggin' MOVES now!! 100% worth it.

Used these to replace motors in my kids toy car. They have worked great for about 8 months now
