Side-to-side movement of the chain and extra stress/torque by the motor are some of the causes for accelerated wear on the drivetrain. Quality IGH's are expensive (Rohloff). A quality hub that doesn't cost an arm but still provide decent performance is very welcome.
For 2019, Shimano is releasing a new IGH called "Nexus Inter 5". https://bike.shimano.com/en-EU/prod...trekking-e-bike-e6100-series/SG-C7000-5D.html
It is by far the lightest IGH (5lbs lesser than Nuvinci and 1lbs lesser than Rohloff). The gear ratio is less than Rohloff and is designed for bikes with 20mph limit in mind. I hope this will be spec'ed on many more bikes.
Some examples are.
Few of the BULLS models in EU.
