50A Bluetooth Electric Bike Controller 48V/60V/72V E-bike Brushless Motor Controller E-ABS Reverse Speed Control Anti-theft

The Brain Behind Your High-Power E-bike Controllers

When it comes to upgrading your electric drivetrain, premium E-bike Controllers make all the difference between a sluggish ride and a responsive, high-torque machine. The LEEK EV 50A Bluetooth Brushless Motor Controller is an advanced drive control unit engineered for demanding riders. Designed to auto-adapt to 48V, 60V, and 72V battery systems, it acts as the central nervous system for your vehicle, managing everything from stepless speed regulation to reversing and emergency protocols.

Who Is This Controller For?

This smart unit is purpose-built for DIY enthusiasts and electric vehicle mechanics who demand precision and power. It is fully compatible with two-wheeled electric vehicles running 1200W to 1500W brushless motors, as well as three-wheeled e-trikes equipped with 1000W to 1200W hubs. Whether you are commuting through city streets or hauling cargo on a heavy-duty tricycle, the 50A rated peak current provides the responsive acceleration and hill-climbing torque necessary to handle the load. The wide voltage adaptive technology automatically identifies your battery specifications upon power-on, ensuring seamless integration without manual voltage switching.

Smart Bluetooth Integration and Thermal Management

What sets these E-bike Controllers apart is the integrated Bluetooth 5.0 functionality, allowing you to connect your smartphone directly to the drivetrain. Using a dedicated mobile app, you can wirelessly adjust current limiting, starting force, three-speed limits, reverse speed, and the undervoltage threshold within a 10-meter range. Real-time data monitoring lets you track battery voltage, operating current, motor RPM, and controller temperature. To support this high-tech workload, the unit is housed in an all-aluminum finned shell that delivers exceptional passive air-cooled heat dissipation. If the internal temperature exceeds 85°C, the system automatically reduces power to protect the hardware, completely shutting down if it reaches 105°C.

Advanced Safety and Drive Functions

Safety and control are paramount when configuring E-bike Controllers for high-speed riding. This controller features an electronic cruise control function for relaxed long-distance riding, alongside a dedicated P-gear that locks the motor to prevent rolling on inclines. The one-click repair function is a lifesaver—if a Hall sensor fault occurs, the system switches to a no-Hall emergency operation so you can safely reach a repair station. With comprehensive under-voltage, overcurrent, and brake power-off E-ABS protections, this IP54-rated unit is ready to elevate your custom build with reliable, programmable performance.

Key Specifications and Wiring Layout

Understanding the technical layout of your E-bike Controllers is crucial for a successful build. The controller features high-power main terminals with two copper posts on the left for battery power input (B+ and B-) and three copper columns on the right for motor phase line output (U, V, and W). Swapping any two phase lines adjusts the motor direction. The low-voltage wire harness includes three sets of sockets: an 8P socket for turn handles and brakes, a 16P main socket for Hall signals and gear switches, and a 6P auxiliary socket for external expansion. With a static standby power draw of less than 15mA, it protects your battery from depletion when the vehicle is locked.
