Product Advantages

1. Professional Disc-Brake System

Equipped with a standard disc-brake mounting position and caliper braking structure, the motor provides precise braking contact and even force distribution. Compared with traditional drum brakes, it offers faster braking response, shorter braking distance, reduced risk of fishtailing, and better directional stability.

It performs reliably in rainy conditions, on waterlogged and muddy roads, and during continuous braking on long downhill sections, helping prevent heat-induced brake fading, weak braking, and wheel lock-up or slipping. It significantly improves safety when carrying passengers or cargo and during high-speed riding, making it suitable for daily commuting, mountain riding, and short-distance transportation.

2. Pure-Copper Brushless Motor Core

The motor uses fully pure-copper, thickened winding coils combined with high-magnetic-force permanent magnets, providing stable magnetic force and higher power conversion efficiency. It offers smooth starts without sudden acceleration, linear and powerful acceleration, and high-torque output for handling steep slopes, uphill roads, and rough terrain.

The brushless design eliminates carbon-brush wear, while quiet operation reduces the buzzing noise common in older motors. The high-efficiency motor core effectively reduces energy consumption. With the same battery capacity, it provides longer range, helping reduce electricity consumption and operating costs over long-term use.

3. Sealed Waterproof and Dustproof Design

The entire motor adopts a multi-layer sealed waterproof structure that effectively prevents rainwater, standing water, mud, sand, and dust from entering the motor. It can handle daily riding in rainy weather, waterlogged roads, and outdoor exposure without easily suffering from water intrusion, short circuits, jamming, rust, or motor burnout.

It is also resistant to high temperatures, overload, and aging. Even during prolonged hill climbing and heavy-load operation, the motor is less prone to overheating, providing stable and durable performance while significantly extending service life.

4. Integrated Hub Wheel Construction

The high-strength aluminum-alloy hub is formed through integrated die casting, providing a strong structure with excellent impact resistance, deformation resistance, compression resistance, and wear resistance. It can easily handle everyday road bumps and gravel impacts without easily cracking or becoming dented.

Standard universal mounting positions support 14/16/18/20-inch mainstream electric bicycles, folding electric bicycles, and commuter electric vehicles. The motor can directly replace the original motor without modifying the frame or performing complicated wiring, making installation convenient and easy even for beginners.

Precision Engineering Details

1. High-Precision Hall Sensors

High-quality Hall components are built into the motor to provide sensitive and stable signal transmission, smooth speed control, and stable starting and stopping. This helps prevent hesitation, sudden acceleration, and inconsistent speed, providing precise control and compatibility with 99% of mainstream universal controllers.

2. High-Quality Silent Precision Bearings

High-strength, wear-resistant precision bearings provide smooth rotation with low resistance, reducing power loss and riding noise. They remain stable and resistant to loosening or deformation during long-term high-speed operation, resulting in smoother riding and more consistent range.

3. Thickened Corrosion-Resistant Housing

The housing features a reinforced, thickened construction combined with anti-rust baked-paint treatment. It is scratch-resistant, corrosion-resistant, and aging-resistant, maintaining its appearance and performance during long-term outdoor use.

4. Thickened High-Flexibility Wiring

The disc brake hub motor uses thickened, high-temperature-resistant wiring that withstands both cold and heat and is resistant to breakage. It provides stable conductivity and helps prevent poor contact, unexpected power loss, and shutdown, ensuring consistent power output while riding.

FAQ

Q1: How should I choose between the Torque Version and the Speed Version? What is the difference?

A:

① Torque Version: Strong starting power, excellent hill-climbing ability, suitable for carrying passengers or heavy loads, underground parking ramps, and food-delivery applications. It has a moderate top speed and more stable range.

② Speed Version: Softer starting response with a higher top speed, suitable for solo commuting, users who prioritize speed, and riding on flat roads.

For daily household use and carrying passengers, choose the Torque Version. For speed upgrades and flat-road commuting, choose the Speed Version.

Q2: How should the motor phase wires and Hall wires be connected? Will incorrect wiring damage the motor?

A: The three thick phase wires can be connected in different combinations. Rotate the wheel and adjust the connection until the motor runs smoothly without vibration. The thin Hall wires must be connected strictly according to the corresponding colors.

Incorrect wiring generally results in reverse rotation, vibration, or the vehicle not moving, rather than burning out the motor itself. Always disconnect the power supply before wiring.

Q3: My original vehicle uses a 48V battery. Can I use a 60V motor?

A: Direct mixing is not recommended. The motor's rated voltage must match the battery and controller voltage.

A low-voltage battery powering a high-voltage motor may result in insufficient power and excessive heating, while a high-voltage battery used with a low-voltage motor may damage the winding insulation and cause permanent damage.

Q4: Does a higher-power motor mean higher speed and longer range?

A: No. A higher-power motor provides stronger acceleration and a higher potential top speed, but under the same riding conditions it may consume more electricity and result in shorter range.

With the same battery capacity, a properly matched motor can provide better energy-conversion efficiency and range. For daily commuting, there is no need to blindly choose a high-power motor.
