Does Your Upgraded Motor Still Lack Power?
Replacing an old electric vehicle motor should improve performance. But some upgrades still struggle with heavy loads and hills while using more battery power. This wastes money and makes daily work harder.
The Avetlink AK high-torque brushless motor kit uses military-grade magnetic steel sheets and a dual-loop control system. It delivers steady torque across a 48V–72V voltage range.
Tests showed that a vehicle fitted with the kit and its matching AK controller maintained 25 km/h while carrying 200 kg up a 15° slope. Driving range was 40% longer than with an ordinary motor upgrade.
The kit is especially suitable for upgrading older electric cargo tricycles.

Three Key Advantages
- Smoother power: An angled-pole winding design reduces torque fluctuations to one-third of those in traditional motors.
- Temperature protection: Smart temperature control supports stable operation in ambient temperatures from −30°C to 80°C.
- Easy compatibility: The modular design works with most mainstream electric motor control systems.
Installation Tips
1. Measure the original vehicle’s axle diameter before installation.
2. Use a smart AK electric tricycle controller rated at 60A or higher.
3. Retighten all connections after the first 100 km of operation.
Frequently Asked Questions
Q1:Do I need to replace the original battery pack?
The kit supports 48V–72V input, so you can keep your existing battery pack if it matches the system’s requirements. This avoids the cost of buying a new battery.

Q2:How difficult is installation?
Detailed installation videos and 3D drawings are included. Users with basic tools can complete the upgrade within three hours.

Q3:How well does it resist water?
The motor is rated IP67, and the controller is rated IP65. These ratings provide protection against dust and water for demanding outdoor conditions.

Q4: Can I adjust the torque?
Yes. The included app lets you adjust torque output settings between 15 N·m and 55 N·m.

Results from Daily Delivery Work
A courier station measured the following results after upgrading its electric cargo tricycles:
- 60% higher daily transport efficiency when carrying loads.
- 45% lower average monthly electricity costs per vehicle.
With strong power, broad compatibility, precise torque control, and smart energy management, the Avetlink AK kit is becoming a preferred upgrade option for older cargo tricycles.
