The Sur-Ron Light Bee X was released June 2018 and is an off-road electric dirt bike weighing 50kg. All of the upgrades in the Light Bee X have made their way its predecessor the standard Light Bee, except the gold chain. A E-bikes imports and distributes the Light Bee X dirt bike for the Australian market. The most significant change is the new improved motor controller known as the X controller. This new motor controller features Vector Control / Field-Oriented Control (FOC), and thereby powers the motor with a variable frequency sine wave, resulting in a slightly higher top speed and greater torque. The new X controller also has kinetic energy recovery in sport mode enabling the motor to recharge the battery, allowing for longer battery life.

The standard Light Bee is available with the X controller or the square wave controller.
