Geekstory 4PCS DC Gearbox Motor TT Motor 200RPM with Leads + 4PCS 1:48 Tire Wheel Anti-interferen DC 3-6V for Arduino Smart Car DIY Robot Toy RC Car (2Pin Male Connector Wire)

These are great for the hobby builds and wires coming off the motors have dupont pins as depected making them perfect for breadboards and quick builds. My only slight con would be that the tires have that bad plastic smell that is usually associated with cheapo plastic products. Also the black plastic isn't very grippy but shouldn't have much problems on indoor projects or in sufficiently heavy builds.Overall, if you're in a hurry and need to get started on a project, this may be a pretty good set to get, I would potentially look at getting just the motors and sourcing other tires, but this is a pretty convenient set to get! Would recommend to those looking for this item and willing to pay extra for speedy shipping.

These work great with my arduino and pi while being easy to use. There isn't too much to say about these motors aside from that they are responsive and are easy to use. If you want to use the yellow housing as just a wheel mount, then you can take the motor out, and itll work as a non powered wheel. If you leave the motor in, then the gears wont allow for the wheel to spin freely.

The set that I have includes 4x 200rpm motors and 4x tires. They are not attached to each other, but you can attach them in whatever configuration you like.The wires coming from the motor are approx. 6" in length and they plug easily into my Arduino project board.These tires look like the same ones you'd see in any tutorial video on making an Arduino RC car and they look/work as expected.Being that the motors are rated at 3-6V, they essentially universally compatible with most electronic project kits.Overall, a wonderful kit that offers customizable wheel options for Arduino projects.

These wheels work great for our little remote control car project.Next step will be to add some sensors and do some semi-automated travel with them.
