Review: Great gearbox and motor combo - Compared to other 30000 rpm motors, these seem to be as fast, or a bit faster, but they are definitely quieter than everything else I have tried. Low end torque is low and two of these have a hard time getting going on an incline or on grass, but on asphalt or concrete they run great. They are better on grass than other gearbox and motor combos I have tried. I have a 15A breaker on each. 7A wasn't enough and the only other parts I had were 15A breakers.
Review: Back to Driving Again - Perfect replacement part for my daughter’s toy car. Install was simple, fit exactly as needed, and had her car running like new in minutes. Durable, quiet, and way better than the original — she’s thrilled to be cruising again!

## Questions & Answers

**Q: Can i use this as an 4wd on a 24v battery**
A: Hello, our gearbox is a 12v motor. It cannot be used in a 24V electric car. Please open your own electric car and check the shape and size of the motor gearbox. Be sure to determine the voltage of your electric car. The voltage is different, the motor is easy to damage

**Q: Does it work on best choice products jeep?**
A: I have these on a jeep from Fitness Fair. Plug and play, but had to buy the upgraded mother board for the extra power.

**Q: How do u tell positive and negative**
A: Since the motor can fit either side, the positive and negative would be opposite depending on what side it is installed on. Just temporarily connect the wires and see if it spins the correct way. Swap the wires if needed.

**Q: I have a 2 seater 3 speed BMW 12 volt power wheels car that is being turned to 24 volt how fast will this go?**
A: If you are running a 24v battery get 2 motors and wire them in series you will get the power you want with less problems

### ⭐⭐⭐⭐⭐ Great gearbox and motor combo

### ⭐⭐⭐⭐⭐ Good quality and powerful motors
*by D***O on February 24, 2024*

Bought 2 of these motors to replace the worn-out (noisy) motors on a kids ride-on car. These motors turned out to be a bitter bigger and more substantial than the old ones, so I had to trim the car's inner body a little to fit them in. Once fitted I realised that the motors were also wider than the old ones, by about a cm and therefore the wheels wouldn’t fit. So, I had a new driveshaft rod made, 2cm longer. Once all assembled again, the motors worked brilliantly! Definitely more torque and the car drives faster than before. So very good motors. I can highly recommend them. Just make sure they will fit your car!
