According to Bike Europe, Shimano has rolled out a software update for its STEPS™ electric bike systems that enables automatic shifting for bikes equipped with the Shimano Nexus 8 Di2 internally-geared hub. Naturally, a manual shifting mode will still be available for those who prefer more granular control.
The automatic shifting system determines shift points depending on the data inputs from the rider’s pedal cadence, the pedal torque (measured at the crankshaft), and the bike’s speed.
So which models does this affect? In the US, there are only a handful of STEPS™-equipped electric bikes, and the main models are the Raleigh Misceo iE and the Raleigh Misceo Sport iE. The Raleigh Misceo Sport iE will not feature automatic shifting because it is equipped with a traditional rear derailleur that shifts by way of a traditional shifter cable and trigger shifter, whereas the slightly more expensive Misceo iE can support automatic shifting because it features an internally-geared rear hub that is compatible with Shimano’s Di2 electronic shifting system.
