Return to index page Introduction of INTER-5E E-BIKE Dedicated Internal Geared Hub The NEXUS Inter-5E is a revolutionary internal geared hub designed specifically for the unique demands of E-BIKE riding. It can withstand much higher pedaling forces, even while shifting (+180% compare with SG-C6000 series) by optimizing shift pattern design.

Also, riders can always manually shift into the gear they want, even in auto mode. When they do, the SHIMANO STEPS system uses a learning function to recognize the manual shift operation and automatically fine-tunes future automatic shift timing to the rider's liking.
