Two Wheels Balance Car Chassis with JGA25 Motor Kit


This product consists of two high-precision coded motors and corresponding motor brackets and an acrylic base plate for easy construction of the balance car model. Of course, you also need to prepare the corresponding control board and sensor to achieve your creativity.

The kit uses JGA25 DC geared motors and optical encoders for higher motor control accuracy and double-layer acrylic plates for easy placement of sensors and development boards.

With this kit, you can DIY assemble the balance car, mini Segway, select the right sensor and development board, and maintain the balance of the body by controlling the rotation of the motor. In this process, you can learn the PID algorithm and learn how to control the motor. Of course, you must first have a balanced car chassis and assemble it.

The Motor parameters:

Motor voltage 3-12V
Motor current 120mA @12V
rated power 2W
specified load
Blocking current 3.5A 
Stall torque 8kg
No-load speed (without deceleration) 32rpm/min
Encoder accuracy 360CPR
Reduction ratio 1:34
Encoder voltage 3.3-5V
