Breaking the Bicycle Shifting Game with Shimano's Q'Auto

Say goodbye to fiddling with gear shifters, thanks to the revolutionary Q'Auto - an automatic gear shifting system for bicycles, crafted by Japanese powerhouse Shimano. No batteries required! The power comes solely from the force of your pedaling.

Designed for urban, trekking, and gravel bicycles (even electric ones), Q'Auto is a game-changer for cyclists, bringing unmatched simplicity to their rides. Its components consist of a modified Shimano Cues hub serving as a generator, a wireless gear shifter, and a Di2 controller secured on the handlebar.

When you start pedaling, the spin of the rear wheel fires up the dynamo hidden within the hub. This, in turn, powers a lithium-ion capacitor that fuels the gear shift machinery, omitting the need for conventional batteries. The hub is also home to a microprocessor and sensors, which track your speed, cadence, and the road's slope.

Q'Auto analyzes these details, executing a smooth gear shift - one notch either up or down - to optimize your pedaling rhythm. Through an app or handlebar buttons, you can select from three riding modes - slow, medium, or fast.

Feeling underwhelmed? Don't worry, you can quickly shift to manual mode and adjust gears on your own accord temporarily. Q'Auto's algorithms swiftly learn your preferred riding style and adjust the automatic mode to suit you perfectly within a mere six kilometers of cycling.

Look forward to Q'Auto's integration with new bicycle models, such as the Rose Sneak 3 EQ, and as a retrofit kit for compatible bikes. While prices and release dates haven't been revealed just yet, we can't wait to see the next chapter in efficient, battery-free cycling!
