Adaptive Electric Tow Platform for Human-Centered, Low-Carbon Transportation

The E-Traction Tow Unit is an intelligent, motor-assisted trailer designed to enable any rider to tow heavy loads (cargo or even additional passengers) with virtually zero added effort. The system integrates a custom battery pack, advanced BMS, electric drive motor, and precision load sensors into a coordinated control platform that automatically provides traction support based on towing demand. Capable of assisting on slopes up to 10%, the unit includes full safety logic, braking control, and regenerative braking for extended range and improved energy efficiency. By eliminating the physical strain traditionally associated with towing, this technology broadens the usability of bicycles for families, delivery services, and mobility-constrained individuals. Built as a scalable, modular platform, the E-Traction Tow Unit establishes the foundation for future innovations—including a motor-assisted auto-tow system for small cars, helping households accomplish larger transport tasks without purchasing an SUV or truck. The project advances sustainable transportation, optimizes resource efficiency, and enhances inclusivity by expanding who can confidently and safely rely on active and low-carbon mobility solutions.

The Team 

This project is undertaken by a dedicated team of five undergraduate students from SFU’s School of Sustainable Energy Engineering, who have chosen to take on the challenge as their senior Capstone Engineering Project. Running from September 2025 to April 2026, the capstone will deliver a working prototype of the E-Traction Tow Unit at Technology Readiness Level (TRL) 6, along with complete engineering design documentation, testing procedures, and system integration plans.

The capstone courses are instructed and supervised by Mina Xu and Gordon Mc-Taggart Cowan, who provide academic oversight for the project. Technical consulting support is provided by Igancio Galiano, and the official project client is the CREATE Lab.
