Shimano has officially unveiled its Q’Auto system for battery-free automatic shifting on non-electric bikes, meaning that manual shifting is no longer required.

We first reported on Shimano Q’Auto last year, although we didn’t have a launch date at the time. Shimano has now gone public with its latest innovation.

> Shimano’s Q’Auto automatic shifting technology touted to launch in 2025, as cycling components giant admits it “can’t break Bosch’s hold on e-bikes”

Obvious question: what does Q-Auto do?

Essentially, the idea is that Q’Auto independently puts you into the right gear without you needing to think about it – or do anything.

Next obvious question: what’s the benefit?

Shimano says, “Until now, fully automatic shifting was only possible with advanced e-bikes. Shimano’s newest shifting technology takes that concept and turns it on its head and combines the joy and simplicity of riding a mechanical bike, with electronic shifting. Q’Auto is an innovative technology designed to make cycling more enjoyable and accessible for riders of every skill level.”

Okay, shifting is hardly the most arduous task, but we can see that some people would prefer not to have to think about it.

What’s to say Q-Auto will work to your preferences, though? We all ride at different cadences, and a gear that’s perfect for one rider might be way too hard for a less fit friend. Shimano has thought of that.

“Its battery-free design and adaptive learning software allow for an entirely new type of bike that keeps riders in the right gear and adapts to your riding style, allowing the rider to focus solely on the road ahead,” it says.

“Adaptive learning”? Shimano says that the Q’Auto system works to your personal preferences.

“With the Di2 shift switch, riders can provide immediate feedback, so as not to disrupt their riding flow,” says Shimano. “By tapping the switch to adjust to a different gear, the system will select that gear and remember this setting for similar situations.

“With over 6,500 possible algorithmic patterns to choose from, Q’Auto will adapt to each riding style and any challenge it encounters.

“Over time, the bike becomes uniquely yours—shifting for you when you prefer—from (almost) the very first pedal strokes. The more you ride, the more in-tune the rider and their bike become.”

In short, Q’Auto is designed to remember your individual shifting patterns and learn to behave accordingly.

What about charging? There’s none to worry about. Shimano Q’Auto is a battery-free system. It will debut with Shimano’s Cues FH-U6060 freehub, which is designed specifically for automatic shifting. It has a dynamo function that generates power as you ride.

“Inside the freehub, there are three sensors to track speed, cadence and slope, allowing the intelligent Q’Auto to collect power while riding and storing the electricity needed for performing shifts,” says Shimano.

Shimano says that the Li-ion capacitor can store power for over a year.

As well as the freehub, the system uses a Cues RD-U8050-SGS/GS rear derailleur and SW-EN605-R wireless shift switch.

The rear derailleur is compatible with all of Shimano’s wireless Di2 switches and shifters – flat handlebar and drop handlebar.
