E-bike Di2 Internal Geared Hub Automatic Shifting (INTER-8/INTER-5E)

EP8/EP6/E6100 and E5000 series drive units in combination with a Di2-compatible 8/5 speed internal geared hub offer full automatic shifting. The SHIMANO STEPS system automatically selects and shifts into the optimum gear, based on the number of crank rotations and speed.

When riders manually shift in auto mode, the SHIMANO STEPS system uses a learning function to recognize the manual shift and automatically fine-tunes future automatic shift timing to the rider’s liking. This offers a stress-free ride, eliminating the need for the rider to worry about whether they’re in the right gear or have to change gears after an abrupt stop.

Intelligent Walk Assist

When walking the bike up a mountain trail, intelligent walk assist automatically adjusts drive unit output torque to keep the bike speed at 4 km/h no matter which gear ratio is used.

 

Starting with EP801, mechanical walk assist has been improving to the same level as Di2 intelligent walk assist to make off-the-bike handling even easier for more riders.

Start mode

Start mode, which automatically shifts to a favorite gear for an easy re-start after stopping for a traffic light, is especially useful in urban areas where stop-and-go riding are frequently repeated.
Also, Automatic shifting, which automatically shifts to the optimum gear based on the rider’s cadence and speed, recognizes the manual shift operation by the learning function and automatically fine-tunes future automatic shift timing to the rider’s preference, is more comfortable ride. With the E-TUBE PROJECT Cyclist app, the starting gear and the gear shift timing can be customized.
