Description This product is made of high-quality aluminum housing rubber and pure copper coil as raw material and adopts a brushless motor, which can provide you with higher quality assurance. Its high speed, high torque, and high power will provide strong support for your work efficiency. Whether it is an electric motorcycle, a beach bike, or other mechanical equipment, it can be a powerful power supplement. High Applicability: This product is universal for 48V/60V/72V in many styles, thus having high adaptability. High-quality Material: This product is made of aluminum housing rubber and pure copper coils, with high-temperature resistance, low noise, anti-corrosion, and anti-rust properties. Brushless Motor: The brushless motor is more efficient in converting electrical energy into mechanical energy because there does not have friction loss. And since brushless motors have permanent magnets on the rotor, it is easier to produce high torque. Reversible: The product can be operated clockwise or counterclockwise by the motor's reversing wire or the handle reversing switch, so as to meet your various usage needs. Multi-function Controller: The controller has an electronic brake, 3 speeds (low, medium, and high speed), reverse function, indicator light, and power lock function, which makes the use more precise and easy. High Safety: The product has an IP33 protection level and an E-class insulation level, which can provide higher safety for your use. Details Anti-slip Handle: The diamond-shaped handle surface can effectively enhance friction, thus making the grip more comfortable and stable. Feet: The feet on the bottom of the motor can effectively improve the stability of the motor, thus ensuring a more stable and efficient operation of the product. Application This product is suitable for electric motorcycles, beach bikes, go-karts, modified bicycles, mechanical equipment, etc. Specification Color: Silver, Black Model: BM1109 Material: Aluminum, Pure Copper, Rubber Assembly Required: Yes Brushless Motor Voltage: 48-72V Load Weight: Approx. 100-200kg/220.46-440.92lbs No-load Current: 8.8A Rated Current: 43A No-load Speed: 6000rpm Rated Speed: 4900rpm Rated Torque: 5.4 N.m Motor Efficiency80 Controller Voltage: 48-72V Power: 3KW Protection grade: IP33 Insulation grade: E Gross Weight: 6.9kg/ 15.21 lbs Net Weight: 6.2kg/ 13.67 lbs Leg Spacing: 11.7cm/4.61in Leg Height: 5mm/0.2in Interface Length: 29mm/1.14in Motor Size(*L): 10.7*13.4cm/4.21*5.28in Package Size: 39*35*25.5cm/15.4*13.8*10in Package Included 1 * Motor 1 * Controller 1 * Foot Pedal Throttle 2 * Lock Keys 1 Pair * Handlebars 1 Set of T8F Chain and T8F Chain Ring All Accessories for Installation Notes 1.
