Q'Auto e-shifting system: Shimano presents self-sufficient Di2 shifting system with its own power supply

Shimano is venturing into previously unexplored territory with the new Q'Auto system. The Japanese component manufacturer presents an automatic Di2 shifting system that has been specially designed for non-motorised everyday bikes. In contrast to previous electronic shifting systems, Q'Auto does not require a separate battery.

Instead, a dynamo function integrated into the rear wheel hub generates the required energy itself. The system is therefore aimed specifically at gravel, urban and trekking bikers who want to benefit from the advantages of electronic shifting without having to worry about regularly recharging a battery.

The centrepiece of the system is the newly developed Shimano Cues FH-U6060 Freehub rear hub. It combines the functions of a classic freehub with an integrated dynamo and sensors for speed, cadence and tilt angle.

The control unit uses this data to select the optimum gear in every riding situation. By generating energy directly in the hub, there is no need for an external battery, which makes the system particularly low-maintenance and suitable for everyday use.

Adaptive self-learning function for a customised switching experience

Another special feature of Q'Auto is the integrated self-learning function. The system continuously analyses driving behaviour and adapts the gear changes to the driver's individual preferences.

For example, if an automatic gear change is overridden manually, Q'Auto memorises this preference for similar situations in the future. The system should therefore be able to adapt to any riding style. According to Shimano, the more the bike is used, the more precise the tuning to personal requirements becomes.

Despite the automatic function, the rider always retains full control. The wireless SW-EN605-R switch allows manual intervention in gear selection at any time. These interactions in turn feed into the system's learning process. In this way, Shimano promises that every user will receive a customised shifting experience over time.

Compatibility & components of the new Q'Auto system

Q'Auto was developed with a wide range of compatibility in mind. The system can be combined with Linkglide 1x10 or 1x11-speed cassettes. The specially developed RD-U8050-SGS/GS rear derailleur is also compatible with the complete range of Shimano Di2 wireless shifters and shift/brake levers for flat and racing handlebars. This enables flexible integration into various bike types and cockpit configurations.

The Shimano Cues FH-U6060 freehub rear hub is available in versions with 28, 32 and 36 spoke holes and uses the 142 x 12 mm E-Thru standard. An integrated Li-ion capacitor stores enough energy to keep the system ready for use even during longer downtimes. Shimano states that the stored energy is sufficient for more than a year.

Area of application & target group

With Q'Auto, Shimano is particularly targeting everyday cyclists and commuters who want to benefit from the advantages of electronic shifting without always having to worry about charging batteries on time.

With this system, Shimano wants to motivate even more people to cycle, regardless of experience or riding ability, by always offering optimum gear selection. The automatic gear shifting system could really come into its own in urban environments with frequent starts and changing speeds.

Shimano also sees potential for trekking bikes and gravel bikes. This is where Q'Auto could really come into its own, especially on longer tours or on variable terrain, by taking the strain off the rider and ensuring efficient power transmission. The combination of automatic function and the option of manual intervention promises maximum flexibility.
