Shimano couples introduction of its first mountain bike drive with an updated E-Tube Project software. The revamped E app provides new customization options in a user-friendly layout that’s easy to access for quick and easy changes. The E-Tune Ride app, which turns a smart phone into a cycling computer, provides expanded information and adds ride recording and mapping features. Next generation e-tube wires have increased speed and bandwidth in a smaller and lighter package.
EP8 delivers up to 85 Nm of torque, a 21-percent increase over the STEPS E8000 motor platform. The magnesium drive unit casing design delivers a 300g weight loss in a 10-percent smaller form factor. The EP8 drive unit shape more smoothly integrates with new e-bike frames for improved ground clearance and a more compact overall package.
Heat dissipating materials, increased surface area in the case, and a refined heat management algorithm improve heat resistance, allowing more torque to be applied even as the conditions become more challenging. Thanks to a new seal structure and gear design, drag is reduced by 36 %, getting closer to the normal pedaling feeling of a traditional bike.
