EBMX X-9000 Ultra Bee Power Kit




Motors and Controller Bundles are expected to begin despatching from mid November 2023. 

Slightly bigger with an 80mm Stator thickness and more powerful than its little brother the XLB-60

40KW rated & designed from the ground up to handle the heat, 180C rated windings with U42H magnets.

Custom IPM rotor design and industry leading 1mm rotor air gap revving out to rated 12000RPM.

Encoder based motor control for increased low end torque response and smooth predicable power delivery

We built these motors to stay cool under race conditions to ensure you focus on your riding and not your motor temperatures. It doesn’t matter if you are on the track, street or local trail, if you want the best, then this motor is for you.

The EBMX motor range has been specifically designed to surpass the performance of other motors in their classes.

In contrast to many of our competitors who utilize hall sensors, we have opted to incorporate encoder sensors in our motors. This decision stems from the fact that encoder sensors demonstrate greater stability under demanding riding conditions. While hall sensors rely on estimated rotor positions, encoder sensors consistently provide precise angle measurements of the rotor’s position. Hall sensors are typically employed for tracking motor position during start-up and up to approximately 2000 rpm, after which the motor operates in a “sensorless” manner. However, during intense riding situations such as wheel spinning and sudden deceleration combined with rapid throttle adjustments, hall sensors angle detection can result in substantial current spikes in the controller. This can pose significant issues for many controllers, leading to tripping and loss of throttle power, although this is less prevalent in the X-9000.

Encoder sensors, on the other hand, are capable of tracking motor position at all speeds and do so more frequently than hall sensors. As a result they can deliver a smoother more responsive and controllable powerband and they do not generate the same type of current spikes that often cause controller issues. Furthermore, they contribute to improved low-end torque control and overall motor response.

EBMX motor have been custom built and are finely tuned to work with the EBMX X-9000 controller.

Our new motors have been engineered for performance enthusiasts and experienced riders in controlled environments. These motors are significantly faster than standard motors, and their extreme speed can pose serious risks if not handled with caution.


  1. NOT INTENDED FOR ROAD USE: EBMX Motors are NOT designed for use on public roads or crowded areas. These motors are strictly meant for off-road use and controlled environments only.
  2. EXPERIENCED RIDERS ONLY: These high-performance motors are recommended for experienced riders who possess the necessary skills and expertise to handle powerful machines. Novice riders are strongly advised against using our motors.
  3. USE WITH CAUTION: The enhanced speed and power of our motors require extreme care and attentiveness. Always exercise caution and be aware of your surroundings when operating our products.
  4. UPGRADE SAFETY EQUIPMENT: It is crucial to ensure that your bike is equipped with upgraded brakes and other safety features capable of handling the increased speed and power provided by our motors. Using the motor with stock brakes or inadequate safety measures may result in accidents and severe injuries.
  5. ADHERE TO LOCAL LAWS: Familiarize yourself with local regulations and laws pertaining to off-road vehicle usage in your area. Always ride within designated areas and private tracks that allow for safe operation.
  6. KEEP AWAY FROM CHILDREN: Our motors are not toys, and they must be kept out of reach of children. Never allow minors or inexperienced individuals to operate these motors.
  7. RIDE RESPONSIBLY: Ensure that you are in a sound state of mind and not under the influence of any substances that could impair your judgment before operating the motor.

By purchasing and using EBMX Motors products, you acknowledge and understand the inherent risks associated with high-speed off-road motor use.
