Trolley Modification Accessories: Low Speed Rear Axle with High Torque 48V Motors 500W-1200W Complete Set

Converting a standard trolley into a low-speed, high-torque electric vehicle is straightforward with this complete rear axle modification kit. Rated at over 400W, the low-speed rear axle delivers strong pulling power for moving heavy loads in workshops, warehouses, farms, or construction sites. The kit includes all essential components: motor rear axle, two pneumatic tyres, controller, wiring, turn handle, brake assembly, and mounting hardware. With four motor power options from 500W to 1200W, you can select the torque and speed characteristics that best match your load requirements and terrain.

Key Components and Specifications

Each motor option is paired with a corresponding rear axle assembly, controller, and wiring harness to ensure compatibility. The pneumatic tyres provide cushioning and grip on uneven surfaces, while the brake lever and line allow for controlled stopping.

Motor Power Options

Choose between 48V 500W, 800W, 1000W, or 1200W motors. The 500W and 800W variants are suited for lighter loads and flatter terrain, while the 1000W and 1200W options provide extra torque for steeper inclines or heavier payloads. All motors operate at 48V and are designed for low-speed, high-torque applications typical of trolley conversions.

Complete Wiring and Control Set

The kit comes with a controller, wiring harness, and a turn handle for throttle control. The brake lever integrates with the brake line for mechanical braking. An electron microscope and electricity meter are also included to help monitor electrical parameters during operation.

Mounting Hardware Included

A U-shaped screw five-hole plate is supplied to secure the rear axle to the trolley frame. This mounting plate provides a stable attachment point, but you will need to measure the bridge width (distance between frame mounting points) on your trolley to select the correct axle option.

Installation and Integration

Installation requires basic mechanical and electrical skills. The kit does not include a battery or charger, so you will need to source a suitable 48V battery pack separately.

Mounting the Rear Axle

Attach the U-shaped screw five-hole plate to the trolley frame using bolts that match the axle mounting holes. Secure the rear axle assembly to the plate, ensuring alignment with the trolley's existing wheel mounts. Adjust the position to maintain proper chain or belt tension if using a chain drive.

Wiring the Controller and Motor

Connect the controller to the motor, battery, and turn handle as per the included wiring diagram. The electricity meter can be wired in line to monitor voltage and current. Ensure all connections are insulated and protected from moisture if the trolley is used outdoors.

Brake and Tyre Setup

Mount the brake lever on the handlebar and route the brake line to the rear brake mechanism. Inflate the pneumatic tyres to the manufacturer's recommended pressure before first use. Check for any leaks or damage to the tyres.

Practical Use Cases

This low-speed rear axle is ideal for converting manual trolleys in agricultural, industrial, or logistics settings where electric assist reduces physical strain.

Workshop and Warehouse Use

Move heavy machinery, pallets, or storage racks with less effort. The high torque at low speed allows precise positioning without sudden acceleration.

Agricultural and Outdoor Use

Use on farm paths, between greenhouses, or on rough ground. The pneumatic tyres absorb bumps and the low-speed axle provides consistent pulling power on slopes.

Custom Projects and Repairs

This kit is suitable for DIY builders repairing or upgrading existing electric trolleys. The modular components allow easy replacement of the axle, motor, or controller individually.

Buying Value and Considerations

This complete set simplifies the conversion process by including nearly all mechanical and electrical components in one package. The main additional cost is a 48V battery and charger. Choosing the correct motor power ensures the trolley meets your torque requirements without over-specification.

Reuse and Maintenance

The motor and controller are designed for long service life with minimal maintenance. Keep the wiring connections clean and dry, and inspect the brake mechanism regularly. Pneumatic tyres may need replacement over time due to wear.

Why Choose This Kit

The broad power range (500W to 1200W) lets you tailor performance to your specific load and terrain. The inclusion of an electron microscope and electricity meter adds diagnostic capability not found in basic conversion kits. All components are matched to work together, reducing compatibility issues.
