24V555 18000RPM Gearbox with 24V DC Motor for Kids Ride on Car SUV Parts, Electric Motor with Gear Box RS550 24 Volt Motor Match Children Ride on Toys Accessories

I'm not sure about the motors because I just bought these for the gearboxes. I put some 775 motors on these with some minor modifications and the gearing is perfect for my 24v 29k rpm motors. Kids been playing with them for about a month on the bigger motors, so I'd say they're pretty good quality gear boxes.

Used two on a 12V to 24V upgrade for a Best Choice Products Jeep (comes stock with a 9k rpm gearbox and 12v motor) - easily moving along at 6 to 7 mph now on a solid surface. Edit: after 2 hours of use, the final drive gears on both beveled out to the point where they won't engage with any resistance from the tire. You can see the secondary gear doesn't fully engage with the final drive gear, so any torque that's applied over time will cause beveled, uneven wear to the point of failure. Looks like a series of washers on the final drive gear may give it enough offset to reduce failure.

Been running these at closer to 30 volts for a year now. Connected to a cheap ebike speed controller on my sons Jeep. The thing pops wheelies and the motors barely get warm to the touch. I did have to replace one after about a year, but these have taken a lot of abuse, and Ive run them above the spec'd voltage the entire time so I really cant complain. And for the money, I can't complain.

My kid has been driving with this motor for 2 hours straight and the motor has good power and very strong I even hoped on it for a bit and I'm 185 pounds

It worked fine for a couple of months until it got hot, shorted out, and almost started on fire.

Bought 2 and installed one of them due to waiting on building a bracket for the 2nd motor. This 1 motor can handle 2 kids and initially it was being used for at least 30 minutes going back and forth. The 20V 5Ah battery still had a full charge.

Upgraded kids ride-on jeep to 24V after they burned up the 12V motors. Bought 18k rpm motors with gears because I thought they would be more manageable than 30k rpm. Motors doing ok, but gear boxes stripped gears. Mix of metal and plastic gear parts, so plastic gears are stripping. Kids weigh 35-45lb so these should be better built to handle small kids. Wish I could find gearboxes with all metal gears, but no luck.

My son only rode on this new motor for 20 minutes and the gearbox broke. Not worth $20 at all. Everything fit perfect and was easy to install but was a cheap gear

Good product.
