Light Bee X
The Sur-Ron Light Bee X was released in June 2018 for the Chinese market only. All of the upgrades in the Light Bee X have made their way to the standard Light Bee except the gold chain. A E-bikes was fortunate enough to obtain 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.
