Product Overview
The Electric Bicycle Dynamic Performance and Road Simulation Testing System is a comprehensive laboratory platform designed to evaluate the performance, safety, durability, and energy efficiency of electric bicycles.
The system supports testing of both mid-drive motors and hub motors, with torque capacities up to 200 N·m and motor input power up to 1.8 kW. By simulating real riding conditions through a dual-roller dynamometer, adjustable loading system, and road simulation functions, the equipment provides accurate data for product development, quality assurance, certification testing, and regulatory compliance.
The platform is suitable for manufacturers, testing laboratories, certification bodies, and research institutions involved in electric bicycle performance validation.

Frequently Asked Questions (FAQ)
What types of electric bicycles can be tested on this system?
The system is suitable for electric bicycles equipped with hub motors or mid-drive motors. It can accommodate a wide range of vehicle geometries and wheelbase configurations.
How does the road simulation testing function work?
The dual-roller dynamometer reproduces riding resistance while obstacle blocks and adjustable loading systems simulate real road conditions, rider weight, and climbing scenarios. This testing logic provides performance data that closely matches actual riding conditions.
Yes. The platform continuously records battery voltage, current, energy consumption, vehicle speed, and travel distance, allowing engineers to evaluate range performance and energy efficiency.
Why is motor efficiency testing important for e-bike manufacturers?
Motor efficiency directly affects battery consumption, vehicle range, heat generation, and overall riding performance. Measuring efficiency under different load conditions helps optimize motor control strategies and improve product competitiveness.
What is the advantage of combining motor testing and road simulation?
Many conventional test benches evaluate motors independently. This system evaluates the entire vehicle under realistic operating conditions, allowing engineers to understand the interaction between motor output, battery performance, vehicle load, and road resistance.
