40A E-Bike Brushless Controller, 36V/48V/52V Sine Wave 1500W/2000W, Compatible with SW900 EBike Display, 3 Modes, IP54 Waterproof, Aluminum Alloy Shell for Electric Bicycle E-Scooter Motor Control

• 【Multifunctional E-Bike Controller】This 36 V/48 V/52 V, 40 A brushless ebike controller delivers a muscular 1,500 W–2,000 W output. Intelligent triple-mode sine-wave technology (Hall-sensor, sensor-less, and pure sine-wave) guarantees silky-smooth power and wide compatibility—perfect for upgrading any e-bike.
• 【Aluminium Housing – Cool & Tough】The CNC-milled alloy shell acts as a heat sink, preventing thermal overload and shielding the PCB from impact and moisture. Our e bike controller is built for British weather and hard miles, it keeps performance consistent and service life long.
• 【Precision Control – Safer Rides】Advanced algorithms give you rock-steady cruise speeds and instant, progressive braking. Commute in traffic or carve country lanes—every journey feels controlled and confidence-inspiring.
• 【Plug-and-Play Harness】Custom waterproof connectors and silicone wiring resist vibration and corrosion, cutting contact failures to near zero. This e-bike controller fits most e-bike frames and integrates cleanly with SW900 and other LCDs.
• 【Check Before Checkout】Confirm motor voltage, wattage and connector type match your system. Once paired, enjoy buttery acceleration, stronger hill climbing and safer deceleration across any terrain.
