Efficient E-Bike Drive Systems

Shimano has introduced the EP5 motor, a new mid-drive motor designed for e-bikes. The EP5 motor delivers 60 Nm of torque and 250 watts of continuous power, making it suitable for Class 3 e-bikes with a top-assist speed of 28 mph. The motor is designed to provide a balanced assist output, enhancing the riding experience for both urban and sport cycling. With a weight of 3 kg, the EP5 motor integrates seamlessly with the bicycle frame, maintaining a natural look and feel.

One of the standout features of the EP5 motor is Shimano's AUTO SHIFT algorithm, which automatically adjusts the gear ratio based on speed, cadence, and torque. This technology ensures that riders can maintain optimal gear settings without manual adjustments, providing a smoother and more intuitive riding experience. The EP5 motor is compatible with Shimano's second-generation battery management system, supporting efficient energy use and extending the range of e-bikes. With customizable power settings through the E-TUBE PROJECT app, riders can tailor the assist character to their preferences.

The EP5 motor is part of Shimano's commitment to enhancing the e-bike experience by combining performance, efficiency, and user-friendly features. By offering a mid-range motor option with advanced technology, Shimano aims to make e-bikes more accessible and enjoyable for a wider range of riders. The EP5 motor's integration with existing Shimano systems ensures compatibility and ease of installation, further supporting the adoption of e-bikes as a sustainable mode of transportation.
