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

Spliced the 6v Audi R8 power wheel and hooked up these on both sides. Works great, fit perfectly, upped the speed considerably.Used the Ryobi power adapter for a battery I already had

I purchased 2 of these units for my son's Walmart spiderman vehicle and upgraded it's fuse and the results were outstanding the units have made such a more powerful and enjoyable ride for my 3 yr old. The units have been on his vehicle for about a month with constant use and they are holding up very well and he can even ride in the grass now with no issues and the speed is on the mark. Very little battery power loss but i did upgrade the battery and he rides so far about an hour or more without any issues.

They worked exactly as described to fix wheels that stopped spinning on our sons battery firetruck that was purchased from tractor supply. Great price. Seems to be holding up well possibly longer than factory ones that came on the truck. No noticable change in Speed

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.

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

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.

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!
