Whereas automatic gear-shifting for bikes is not unprecedented, such setups usually require batteries that must be regularly recharged. That is not the case with Shimano’s new Q’Auto system, nonetheless, because it attracts on the rider’s personal pedaling energy.
Designed primarily for city, trekking and gravel bikes – each common and electrical – Q’Auto consists of three components: a modified Shimano Cues rear freehub, a linked Cues wi-fi rear derailleur, and a handlebar-mounted Shimano Di2 wi-fi shifter.
Because the rider pedals, the rotational movement of the rear wheel spins up a dynamo within the freehub. That dynamo in flip fees a lithium-ion capacitor, which powers the derailleur’s gear-shifting actuator. The freehub additionally incorporates a microprocessor, together with sensors that monitor pace, cadence and incline.

Primarily based on knowledge supplied by these sensors, Q’Auto mechanically shifts gears – transferring up or down only one gear at a time – with a view to keep a set pedaling pace. Using an accompanying app or bodily pushbutton controls, riders can select between Gradual, Center and Quick pedaling preferences.
After all, some customers could not initially “agree” with the system’s presets. For that purpose, riders can quickly change over to Guide shift mode, then shift gears themselves utilizing the Di2 shifter. As they achieve this, Q’Auto’s AI brains will study their biking model, then apply that data to its Auto-shift mode. It could possibly achieve this inside simply 6 km (3.7 miles) of using.

Q’Auto can be provided each as commonplace tools on third-party bikes, and as a retrofit for present appropriate bicycles. There’s presently no phrase on pricing or availability.
