@surronbikes388: So much potential on the Ultra Bee with just an X-9000 controller. From the factory this bike is capable of 12.5KW, we tuned it to 17KW through the EBMX app and X-9000 controller to unleash its full potential on the stock battery. Lucky it's got traction control... Pm me if interested #fypシ゚viral #surron #surronbike
