The automatic transmission of Ultima electric bikes

 

The Valeo Cyclee automatic transmission : the technology that transforms the Ultima Mobility e-bike experience

 

In the world of electric bikes, we often talk about range, battery, or motor power. But if there's one innovation that's truly changing the way we pedal, without many cyclists yet realizing its impact, it's the integration of the motor and transmission into a single, intelligent unit.

This is exactly the choice made by Ultima Mobility, a French brand recognized for its innovative electric bikes, with the integration of Valeo's Cyclee automatic gearbox into its Multipath and Larrun Longtail ranges.

And this integration changes everything! Fluidity, security, performance, accessibility, etc…

One thing is for sure, this automatic transmission completely transforms your riding experience and ushers Ultima bikes into a new era…

 

 

What is an engine with an integrated automatic transmission ?

 

Actual operation of the Valeo Cyclee automatic transmission : the torque sensor, the key element !

To understand what makes the Valeo Cyclee system so different, we must first look at its internal workings.

At the heart of this technology lies an extremely precise torque sensor, capable of continuously measuring the exact force you apply to your bicycle pedals. Where entry-level e-bikes only detect the simple rotation of the cranks, Valeo's device analyzes your actual effort.

In other words, it knows when you push, with what intensity, on what slope you are moving and at what speed you are moving.

 

Real-time data processing to continuously improve your experience

This data isn't just used to power the electric assist. It's processed in real time by an algorithm capable of interpreting your movements at an extremely high frequency. Thanks to this continuous analysis, the motor automatically adjusts its power output, selects the most suitable gear, and smooths out every acceleration.

Everything is designed to avoid jolts, slippage, or jumps between gears. It's this instantaneous processing that gives the impression of precise, smooth, and perfectly controlled driving.

 

A system with a higher level of reliability than that of the market

Unlike some systems on the market that merely mimic an automatic gearbox via an electronic derailleur or a hybrid device, the Valeo Cyclee automatic gearbox is a true mechanical transmission fully integrated into a hermetically sealed and durable casing.

This means that no cables are exposed, no adjustments are necessary, and no synchronization needs to be managed by the user. The motor unit therefore offers a level of reliability that is quite rare in the world of electric bikes and very close to that found in automobiles.

 

How does it work for the user ?

It's simple and hassle-free !

• If you pedal, the motor adapts to you.
• If you force it, it helps you more.
• If you accelerate, it automatically changes gears.
• If you slow down, it downshifts.

The user no longer has to worry about the technology. They simply enjoy the ride in a level of comfort that few competing bikes can offer. But to truly appreciate it, you have to try it first, so why not visit one of our dealers and test it for yourself ? 

The fundamental differences with a conventional transmission

 

When comparing Cyclee to classical systems, the distinctions are clear.

 

A classic derailleur : efficient but exposed

Even a high-performance traditional derailleur remains susceptible to impacts, rain, and wear, and requires regular adjustments. It can derail, soil clothing, and force the cyclist to anticipate every gear change.

 

Internal hub : clean but still manual

Hub-integrated manual gearboxes, on the other hand, are cleaner and require less maintenance, but they still require manual gear changes. They can sometimes grind when shifting gears while stationary or under heavy load, especially uphill.

 

Valeo Cyclee : automatic, intelligent, integrated

With Valeo Cyclee, the approach is radically different. The user doesn't have to do anything: no levers to manipulate, no adjustments to monitor, no unpleasant surprises. The transmission automatically selects the best gear at the most opportune moment, regardless of the terrain or situation. The result is consistently smooth riding, enhanced durability, and uninterrupted comfort, whether in the city or on the most demanding climbs.

 

 

The real benefits for the user

 

Unparalleled comfort : pedaling that adapts to you

One of the first benefits you'll experience with the Cyclee automatic transmission is the immediate feeling of comfort. Whether you've ridden an electric bike before or not, you'll feel the difference from your very first pedal strokes.

You just ride. The bike takes care of the rest. What more could you ask for ?

The automatic transmission adjusts the transmission to maintain a smooth and comfortable cadence, giving the impression of being carried by the bike rather than having to adapt to it.

 

Enhanced safety : lockable motor + balance bike mode

The Valeo Cyclee system not only makes the user experience smoother but also significantly safer, and this is an essential element when it comes to electric bikes.

Security is enhanced thanks to the electronic lock integrated into the transmission. Using the Ultima app (available on the App Store or Google Play Store), the motor can be remotely locked, rendering the bike unusable or impossible to move. Combined with the balance bike mode (a padlock icon appears on the bike's display) which mechanically prevents rotation, and the optional GPS, this provides a genuine theft deterrent, seamlessly integrated into the bike's mechanics.

In other words:

• A thief cannot "force" the transmission
• The bicycle becomes impossible to ride.

 

More intuitive driving: who is this system for and why was it designed ?

With this automatic transmission motor, riding becomes incredibly intuitive, even for people who have no experience with electric bikes.

• No need to understand transmission ratios or anticipate gear changes.
• You don't need to be athletic.
• No mechanical knowledge is required.

The bicycle does everything.

This is precisely what makes it a perfect bike :

• for those who want an intuitive bike
• for those who want a reliable and durable electric bike
• for women in urban attire
• for novice users
• for cyclists tired of mechanical adjustments
• for seniors
• for everyday use
• for hassle-free mobility

In short, Ultima bikes equipped with the Valeo Cyclee system are made for those who want to enjoy a unique experience with an e-bike that naturally adapts to their pace, without the mechanical complexity that comes with it.

An engine designed to last : Valeo's automotive influence

 

Valeo brings 100 years of automotive expertise to the world of electric bikes. And you can feel it when you ride bikes that incorporate this technology.

The components are designed to withstand thousands of hours of use, harsh weather, temperature variations, and repeated mechanical stresses. The casing is sealed, the gears are reinforced, and the internal mechanisms benefit from electronic control comparable to that of a modern car engine.

Thanks to this industrial approach, Valeo Cyclee guarantees a lifespan far exceeding that of traditional systems. It's not a fragile mechanism requiring monthly adjustments. In fact, it's one of the few systems designed from the outset for demanding, long-lasting daily use, while also taking into account the real-world situations users encounter on the road.

 

 

Why is Ultima Mobility one of the few brands to integrate it ?

 

A frame specifically designed for this integrated motor

Integrating Cyclee into a bike is not simply a matter of adding a motor to a frame. This technological unit imposes very specific constraints. It requires :

• a suitable geometry
• an optimized center of gravity
• a structure capable of withstanding mechanical stresses
• a design precise enough to accommodate the engine volume

Ultima's monocoque frames are lightweight, balanced, and produced using a unique manufacturing process that perfectly meets these requirements, allowing for seamless motor integration while enhancing the bike's stability. This process is explained in more detail in the appendix to our article dedicated to the lightweight design of Ultima frames and bikes .

 

A level of technological integration rarely seen on the market

This combination of technologies (unique monobloc frame ; Valeo motor + gearbox; Ultima mobile application with integrated security), uncommon on the market, places Ultima in a category of its own even among french manufacturers of electric bikes.

The Cyclee automatic transmission is not a gadget, it's a new way to ride a bike

 

The integration of the Valeo Cyclee system on Ultima bikes is not a marketing ploy. Today, it represents a new way to experience mobility with :

 

• Superior comfort
• Maximum security
• An integrated and clean transmission
• A powerful and durable engine
