Feature:1. Multi Function: Electric six in one dual mode controller, reversing, three speed (low/medium speed/high speed), cruising, power assist, anti theft lock, brake power off.2. Enhanced Design: Hall/no Hall self checking design, soft start compatible design, enhancing design to make climbing more powerful, flexible auxiliary brake design, more sensitive braking, using overspeed design to increase the speed of electric vehicles to 20 %.3. Low Noise Design: Quiet and low noise design, no noise pollution, all wires are made of high temperature and flame retardant wires, which are safer. Suitable for electric vehicles, electric bicycles, electric tricycles.4. Intelligent Chip: high tech intelligent chip control and management, electric vehicle operation is safer, more convenient and more energy saving. The reinforced screws are durable, and each screw is fixed with waterproof thermal conductive glue, and the waterproof effect is better.5. Aluminum Alloy Shell: thickened all aluminum alloy shell is conducive to heat dissipation to avoid thermal overload, more effectively block the external water source and water steam, strong hardness, good corrosion resistance, good thermal conductivity, fast heat dissipation, and long service life.How to Use:Controller wiring instructions: the controller is connected to the corresponding line interface can achieve the functionSpecification:Item Type: E Bike ControllerMaterial: Aluminum Alloy ShellSize: Controller Box Approx. 18 x 8.5 x 4.5cm / 7.1 x 3.3 x 1.8in(Manual Measurement Allowable Error)Voltage: 48VCurrent: 32±1ABrake Input: High/Low LevelApplicable Motor Power: 500WProduct Function: Reversing, Three Speed (Low/Medium Speed/High Speed), Cruising, Power A
