Automatic shifting technology has arrived in the world of e-bikes, and it could make cycling even more effortless and enjoyable. Shimano, one of the biggest bicycle component manufacturers, has recently introduced two products that they believe will revolutionize e-biking: Shimano Cues Di2 AUTO SHIFT and Shimano FREE SHIFT. Both of these technologies are operable through the Shimano E-Tube Project Cyclist app and designed to help e-bikes shift automatically and overcome some of the difficulties associated with traditional drive trains.

Shimano Cues Di2 AUTO SHIFT

The Shimano Cues Di2 AUTO SHIFT is a re-engineered rear derailleur powered by an e-bike’s onboard battery and motor. The derailleur connects digitally with the rest of the powertrain, allowing for communication between various components. The speed sensor in the rear hub shifts the rear derailleur to a more challenging cog on the rear sprocket as the bike’s speed increases, eliminating the need for the rider to change gears manually to maintain a smooth cadence. Additionally, torque and cadence sensors in the mid-drive motor/bottom bracket assembly help optimize the selected gear for the rider’s effort level.

Shimano FREE SHIFT

On the other hand, the Shimano FREE SHIFT allows e-bikes to change gears while coasting, unlike traditional derailleurs that require the rider to pedal. Battery power from the mid-drive motor engages the rear derailleur, allowing for automatic gear changes. In addition, the bike’s speed and cadence sensors monitor when it slows down and shift into an easier gear, preparing for the next acceleration.

The auto-shift function can be set to auto or manual, with manual shifting allowing the system to learn the rider’s preferred cadence zone, ensuring the auto-shift function maintains the preferred gearing for the rider’s style.

Shimano claims that the automatic shifting technology will reduce the stress of optimizing ride quality and pedal cadence, making the cycling experience more enjoyable. Mountain bikers may find the technology particularly useful, with FREE SHIFT helping to shift to the right gear without pedaling, which can change how bikers think about cornering and focus more on planning their line and maintaining control and acceleration.

However, investing in automatic shifting technology depends on a rider’s preferences and bike compatibility. Riders who prefer the utmost control of their gears may find it redundant, while those who value convenience and want to simplify their cycling experience or try out the latest tech may benefit from it.

Benefits of Auto-Shifting

Auto-shifting can make biking more enjoyable for those who want a more straightforward, less complicated experience. Shimano claims that with the Cues Di2 and FREE SHIFT, riders can focus on the road and enjoy the ride without worrying about gear changes. Additionally, automatic shifting can be especially helpful for mountain bikers who must shift gears frequently while climbing, descending, and cornering.

FREE SHIFT and E-Mountain Bikers

Shimano highlights mountain biking as one of the best uses for auto-shifting. It is common for mountain bikers to encounter terrain changes that require gear changes. Rather than manually shifting gears after the descent, FREE SHIFT adjusts the gear automatically so that the pedal strikes deliver power to the wheel.

In addition, Shimano claims that FREE SHIFT helps mountain bikers focus on planning their lines and maintaining a stable body position for better control and acceleration after corners.

Is Auto-Shifting Right For You?

The answer to this question depends on several factors. For example, if you are an experienced rider who values control over gears, you may need more than automatic shifting. However, if you’re new to biking and struggle with gear changes or a mountain biker who loves playing with the latest technology, automatic shifting could become your new best friend. Remember that you’ll need a compatible e-bike to use Shimano’s latest technology, and you may need to upgrade your entire e-bike to benefit from automatic shifting. Ultimately, the decision to use automatic shifting is a personal one and depends on your individual needs and preferences.
