With the new Q’Auto system, Shimano has launched an electronic automatic shifting system on the market for the first time that is specially designed for classic, analog bicycles — without the need for an additional battery. We tested the innovative system on the new Rose Sneak 3 EQ at this year’s Eurobike and describe our impressions.
The concept: an automatic transmission without a battery
The idea behind Shimano Q’Auto is clever: a dynamo in the rear wheel hub generates the energy required for the automatic and electronic Cues Di2 gear shifting system. This means that no battery needs to be charged or maintained — the system is completely self-powered.
In addition, an integrated AI chip analyzes riding behaviour in real time. Speed, cadence and other factors are evaluated in order to adapt the shifting processes individually to the user’s riding style. The result: the gears should shift almost unnoticed, always at the optimum time and in line with the current situation.
Manual control remains available
Despite the automatic system, you still retain control: a wireless remote switch on the handlebars, which is powered by a small battery, can also be used to control the gears manually. This means you can intervene at any time if necessary — whether on sporty rides or in unforeseen traffic situations.
First impressions on the Rose Sneak 3 EQ
The first production bike with the Q’Auto system is the Rose Sneak 3 EQ, an urban commuter bike with a sporty character. We were able to test the bike with the new gear system at Eurobike. Our impression: The gear changes are very smooth and precise, the system works quietly and unobtrusively. The anticipatory downshifting is particularly impressive, for example when rolling up to a traffic light — you are automatically in the right gear when you restart. After a short period of familiarization, you can concentrate fully on riding. At the same time, it is reassuring to know that manual intervention is possible at any time via the button.
The system really comes into its own on a commuter bike like the Sneak 3 EQ: In everyday use, the automatic transmission ensures a relaxed glide, while ambitious riders can control the gear changes themselves if they wish thanks to the precise electronic control, allowing them to enjoy a more direct, sportier riding style.
We have summarized more information about the Rose Sneak 3 EQ in this article, of course you can also find the bike directly here on the Rose Bikes website.
Conclusion: Clever technology for analog bikes
The Shimano Q’Auto system convinced us in the short test. The automatic system works reliably, unobtrusively and provides a pleasant riding experience. The smart power supply via the dynamo is particularly successful — this keeps the bike free from external power sources and retains the classic advantage over e-bikes: Simply get on and ride off without having to worry about charged batteries.
For urban commuters, touring riders or anyone who wants to enjoy the comfort of an automatic transmission but still wants to rely on a classic analog bike, the Q’Auto is definitely an exciting innovation.
