| The toy you are originally starting from comes with some method to control the motor, often through a foot pedal switch that activates the motor directly or through a relay. The motor is either on or off. Besides optional "fast" and "slow" modes, there is no way to vary the speed of the motor on the original toy. Except for the switch or relay failing, this setup is generally pretty reliable for the tiny stock motors. | The toy you are originally starting from comes with some method to control the motor, often through a foot pedal switch that activates the motor directly or through a relay.

| The Internet has many new, very inexpensive "Chinese Controllers" floating around, in both brushed an brushless forms. They are generally designed for usage in scooters or e-bikes. There are also higher-powered controllers available for golf carts, but are generally much more expensive. | The Internet has many new, very inexpensive "Chinese Controllers" floating around, in both brushed an brushless forms.
