Integrated Dual Ratio Gearbox

Universal Compatibility

Perfectly adapted to 48V-72V wide voltage systems, compatible with 500W-3000W full-power range motors, and universally applicable to over 95% of electric tricycle rear axle interfaces on the market, with no modification required for installation.

Industrial-Grade Durability

It adopts high-strength cast aluminum / alloy shell and precision bearings. The industrial-grade component design ensures stable operation for more than 50,000 hours, with a long service life and low failure rate.

High Torque & Climbing Ability

The optimized gear ratio design enables quick starting and sufficient torque, easily handling heavy loads and uphill conditions in mountainous areas, ensuring stable and powerful operation even when fully loaded.

Product Description

Product Description (Universal for All Differential Gearboxes)
This differential gearbox is a core transmission component specially designed for electric tricycles and light commercial vehicles, supporting a wide range of motor power (500W–2200W) and fully compatible with 48V/60V/72V systems. It is an ideal drive solution for 3-open tricycles, cargo vehicles, and utility electric vehicles.
Built with high-strength housing and precision gear sets, it delivers stable high torque output to enhance climbing and load capacity, perfectly meeting the demands of heavy-duty transportation scenarios. Optimized gear pairing ensures low-noise, smooth operation even under continuous full load, providing a reliable and comfortable riding experience.
The modular or fully enclosed design enables easy maintenance and reduces repair costs. Worn parts can be replaced individually without replacing the entire unit, minimizing downtime for fleet use. The sealed, anti-rust housing provides excellent protection against water, dust, and corrosion, ensuring stable performance in harsh outdoor conditions.
With industrial-grade components and standardized interfaces, it ensures long-term reliable operation, reduces overall maintenance costs, and serves as a cost-effective transmission solution for electric vehicle manufacturers and after-sales markets.

Which motors and power ranges is this gearbox compatible with?

Our gearboxes support 48V–72V wide voltage systems and are compatible with 500W–3000W motors, fitting most mainstream e‑tricycle rear axles on the market.

The gearbox features standard mounting holes and connectors. Basic tools are sufficient for installation, and detailed manuals are provided for quick setup.

With sealed housing and anti‑rust treatment, it is water‑resistant and dust‑proof, reliable even in rainy, dusty, or humid working conditions.

We offer a standard warranty. Please contact our sales team for detailed terms based on your order volume and model.

First check the gear oil level and bearing tightness. If the issue persists, contact our after‑sales support for troubleshooting and replacement options.

High Torque Output

Reinforced gear design delivers strong power transmission for heavy-load tricycles, ensuring stable climbing and acceleration.

Low-Noise Operation

Precision-machined gears and sealed bearings reduce friction, enabling quiet and smooth running even under full load.

Durable & Long-Lasting

High-strength alloy housing with anti-rust treatment, built to withstand harsh road conditions and extend service life.

Easy Maintenance

Modular structure allows quick replacement of worn parts, reducing repair costs and downtime for fleet use.

Gearbox Advantages vs. Ordinary Products

High-strength alloy housing, precision cast, impact-resistant and crack-proof Ordinary cast iron/thin steel housing, prone to deformation and cracking
Precision gear set, wear-resistant material with high transmission efficiency Roughly made gears, fast wear and large power loss
Low-noise design with sealed bearings, low operating decibel No noise reduction design, loud operation and obvious vibration
Full-range compatibility for 48V-72V / 500W-2200W systems Narrow voltage/power range with poor compatibility
Modular structure, easy to disassemble and maintain, reducing after-sales costs Integrated structure, requiring full replacement for partial damage
Anti-rust and sealed treatment, waterproof/dustproof for harsh environments No anti-rust sealing, prone to corrosion and jamming in humid/rainy conditions
