Avetlink AK Low-Noise Gearboxes for European Micro-EVs
As European cities promote car-free centers, quiet, reliable, and efficient electric transport is becoming more important.
Avetlink AK gearboxes are designed for heavy-duty cargo trikes and compact urban passenger vehicles. They provide smooth power transmission and reduced operating noise for everyday city use.
With a focus on reliability and efficiency, AK drivetrain components help manufacturers address the performance and environmental requirements of European urban mobility projects.

Avetlink AK Drive Units for European Cargo Bikes and Micro-EVs
European vehicle manufacturers and fleet operators face several common challenges:
- Quiet operation: Delivery vehicles need to keep noise low in residential areas such as Amsterdam and Berlin.
- Heavy loads, limited space: Cargo bikes may need to carry hundreds of kilograms while keeping the drivetrain compact and lightweight.
- Less maintenance: Fleet operators want components that can cover thousands of kilometers with fewer service stops.
- Better efficiency: Friction wastes battery energy and reduces driving range.
Compact Strength with Quiet Performance
The Avetlink AK drive unit is designed for electric cargo bikes and other small electric vehicles. Its differential assembly combines mechanical strength with a design that reduces operating noise.
Precision-ground gears help support quiet operation, making the AK suitable for applications such as early-morning deliveries in residential neighborhoods.
The heavy-duty differential housing is available in one-piece and split-body designs. These options help manufacturers fit the unit into different chassis, from narrow cargo bikes to four-wheeled micro-cars.
Frequently Asked Questions
Q1: Does the AK meet European noise requirements?
Its precision-ground gears are designed to reduce operating noise. Compliance with the requirements for your vehicle should be confirmed using the relevant noise test results.

Q2: Can it work with high-torque mid-drive motors?
The differential is designed to handle the sudden torque produced by electric motors. The selected AK configuration should match your motor’s torque and installation requirements.

Q3: Can our engineers get technical drawings and 3D files?
Contact Avetlink for available CAD files, technical drawings, and documentation to support integration into your vehicle.
Customer Feedback from the Original Material
“We used this drive system in our new fleet of postal delivery trikes in Germany. It has been very reliable, but the biggest benefit is the noise level—it is almost silent. That is exactly what our municipal customers wanted.”
— Jürgen S., CTO of an Electric Mobility Startup, Munich
