12V Kids Ride On Car Gearbox 550 2Pcs 12V Motor 30000RPM Powered Wheels Electric Motor Gearbox High Speed RS550 Drive Engine for Kids Ride On Toys Car Motor

Good quality for the price.

I replaced them on the power wheel truck and used it for about 1 hour and the motor gear are destroyed from the inside . I can’t return because I passed my window but not sure if I got a bad batch or just bad quality ? I would not buy again

I bought three sets of these, I have 3 kids/Jeeps. My Jeeps came with a12v battery, 12000 rpm motors, rear wheel drive. So, I received the 40,000 rpm motors, hooked them up, and he’d the kids test drive them one at a time. The speed was tremendous and I had it on the lowest of three settings. It rolls (I’m guessing 8 mph versus 4 w/12000 rpm). So, my daughter drives the circle for about 5 minutes, 26 degrees out, when she passes her parking and 3 point turn tests I tell her we’re going up the street. So, I start walking, she stops. The car would automatically turn off. Then, restart, go about 6 feet, turn off. Restart, go about 6 feet, turn off. My two sons did the exact same thing!!! I put the 12000 rpm motors back on and we rolled all over the place without a hitch. Can anyone tell me what’s going on? The voltage read 10 or 11 when it automatically shut down. If I held the rear end up I could run it forever. If I put the kid back in, it shut down. Id love to know what’s up. Any electrical guys out there. Stock ride on, only upgrade was the motors! I only gave it two stars because of the problem I had. Others say theirs worked without a hiccup. But it’s hard for me to think I got 6 bad motors. Something is tripping the circuit.
