In practice the Nexus5 is doing well in terms of handling and riding.

Also contacted Shimano technical service. This Nexus5 is specially designed for e-bikes with a more powerful motor. The bearings and gears are noticeably thicker and firmer. That is why the hub only has 5 gears. The Nexus7 and 8 are actually not intended for the more powerful e-bikes. If the bicycle manufacturers were to follow the specs carefully, they would be best not to mount a 7 or 8 on the power e-bikes.

The technical service of the bicycle manufacturer itself also provides similar information. The installation of the Nexus5 on a number of their bicycle models is a well-considered design choice that is independent of any shortage of certain parts.

NB: calling the technical service gives a little more guarantee that you receive more objective information from technicians on the field, which is by no means the case when calling the sales / marketing.

The dealer himself indicates that he has already delivered quite a few bicycles with Nexus5 without having had any problem so far. With the Nexus 7 and 8 there have been cases of defective hubs.

The general advice is to always start in 1 and Eco mode and only then increase. Just like a car. You also do not start in 3rd or 4th gear.

Does anyone have experience with the SHIMANO Internal Geared Hub Nexus 5-speed for E-Bikes ? It was specially designed for E-bikes with higher torques e.g. Bosch Power Line. The 5-speed apparently withstands better the higher torques than the Nexus 8.
