The Freedom of Design – Revonte ONE for E-Bike Manufacturers

Highly positive is an understatement when describing the reception of the Revonte ONE Drive System by the current market. The automatic & stepless transmission, and highly capable drive unit create a ride experience that needs to be felt first-hand. Another, but till now barely discussed, strongpoint of the Revonte ONE is the freedom of frame design for bike manufacturers and OEM’s. 

And that’s the topic of this article.

One Hardware for Every E-Bike

Versatility was one of the design goals when setting out designing the Revonte ONE. In practical and very brief terms this means that one hardware – meaning the Revonte ONE Drive Unit – can be used in all types of e-bikes ranging from lightweight commuters to heavy-duty cargo e-bikes. This is achieved with ingenious mechanical design found inside the drive unit, as well as the high level of configurability our software provides. 

For product designers, this is very welcomed news since one type of motor interface can be used throughout the lineup. Product managers are another happy group of people since only one drive unit type needs to be ordered and kept in stock to cater for the needs of the whole e-bike portfolio. The same goes for the other components in the drive system such as the battery, and the handlebar controller.

Mounting the Motor

The Revonte ONE Drive Unit employs a dedicated motor mount. When it comes to performance metrics, the drive unit is highly capable, to the extent that it can meet the demands of professional heavy-duty cargo e-bike use. The motor mount was designed accordingly to withstand the loads and stresses caused by the respectable output that the drive unit can give out. 

The motor mount is an open mold design, and the dimensions and all the relevant information is shared freely with our partners. If you are an e-bike manufacturer interested in using the most advanced e-bike drive system around, get in touch at [email protected] 

The theme of versatility, and configurability continues in motor placement. Unlike some other models in the market, the Revonte ONE Drive Unit can be placed in any orientation desired! Want to have the motor tilted to 30° or even 75°? Not an issue. This particular design freedom might be of a high value in cargo e-bikes in which the frame designs are all but set, and the development is ongoing. In addition to this e-bike category, the freedom of design enables innovative, and even futuristic designs such as the P2 by our partner Lavelle bikes. 

Plenty of Battery Life

An e-bike drive system would not be complete without a proper battery – that’s where the Revonte AKKU comes into play! We collaborated with Akkuvision GmbH, to create a top of the line battery using the latest Li-Ion technology to offer a complete, and ready-to-implement, e-bike drive system solution. 

Revonte AKKU is not just some e-bike battery. Offered in 540Wh, and 720Wh capacities with identical form factors, it meets the demands and price points in nearly all cases imaginable. In addition, not only two, or three, but four(!) batteries can be connected in parallel, thus giving an unheard of battery capacity of 2.8kWh!

Easy to Design, Easy to Use

The Revonte ONE Drive System provides an unparalleled ride experience. Easy-to-use, fun, and engaging – just pedal and the carefully honed assistance software will take care of the rest. The ease of use and the amount of “boost” available from the drive unit caters for riders of all ages and abilities. The Revonte ONE Drive System will change how e-bikes are used and thought of.

The same design ethos reaches all the way to the design table of our partners. At every step, we’ve made sure that integrating our drive system into any type of e-bike is not only possible but as simple as it can be. Configuring the ride profiles will provide the finishing touches. 

2021 in Review


Time flies as they say. This is especially true when developing an innovative product such as the Revonte ONE Drive System. A brief summary was in order to bring 2021 to closure, Read further to learn what happened, and even more importantly, what’s going to happen in 2022! 

Development and Testing

It goes without saying that 2021 was extremely dense and condensed when it comes to developing, and refining the Revonte ONE Drive System further, and further. Testing the results of the development work, whether it be hardware or software related, was another side of the coin that produced nearly an equal workload than the development itself. All this is done to ensure the unprecedented ride experience and performance when the Revonte ONE Drive system is released to the market.

Suffice to say, the global economic environment did not make things easier with continuously growing lead times, components, and material shortages. We did navigate the challenging circumstances well, but it did not come without a considerable amount of work in the back end. 

The advent of Cargo e-bikes

We’ve said it previously, but it is worth repeating: cargo e-bikes are going to form a big part of the e-bike market in the future. The utility value of an e-bike that can carry a decent payload can hardly be overstated, in commercial as well as in personal settings.

We’ve partnered with EAV which is the leading company on this front with its forward-thinking approach to design and ability. We are especially excited for the future developments in this field and will keep the collaboration as strong as ever. 

Media Presence

We’ve been pleased to see that features about us have appeared in the cycling media throughout the year. One very notable landmark in the media coverage category was an article published in the prestigious Forbes magazine that got published in April of 2021. 

While we are at it and speaking of media coverage, head to Revonte.com/Company to see the full list of news and media coverage that’s been published to this date! 

For the technically-minded and curious, we also lifted the curtain of secrecy by presenting a video showing how the Revone ONE Drive Unit works. 

Eurobike 

Eurobike is the premier annual event for the bicycle industry. The 2020 edition got cancelled because of the global pandemic, but fortunately, a year later, the show was back in nearly full swing – and, of course, we were there.

The show was a success by all metrics. Media presence and exposure were gained, interesting discussions were had, and important negotiations were made. Without an exception, every visitor on our stand was excited and impressed about the automatic & stepless transmission found on the Revonte ONE Drive System. 


E-bikes equipped with the Revonte ONE Drive System are a category-breaker and will change how e-bikes are ridden and even thought of. 

Moving Forward!

This year will be exciting, and a decisive time period in many ways. The demand for e-bikes is higher than ever and just keeps increasing. The demand for a new drive system and drivetrain technology that is user-friendly, low maintenance, and easy to use is up there as well. We are going to answer that call.


Stay tuned for future news. Big things are coming up in 2022!

Future-proof

The development of e-bike technology is happening fast, and not in a linear fashion. Even though forecasting is difficult, especially when it comes to predicting future events, we are very confident that the Revonte ONE Drive System will stand the test of time for many years to come.

Read further to learn why that is.

Software-first approach

Even though a heavy dose of good old-fashioned mechanical engineering has gone into the Revonte ONE Drive Unit, we describe ourselves as a software development company first and foremost. 

To achieve this type of operation model, we have designed the Revonte ONE Drive System from the ground up as a software-based product. This does not negate the importance of a sound and robust mechanical design – on the contrary. The design of the Revonte ONE Drive Unit is based on a time-tested design that’s been used in a variety of applications, including heavy-duty industrial use. 

By leveraging the features of the mechanical design, and pairing that with highly sophisticated control software, we are able to deliver something very special

With a sturdy base that’s standing on a pair of legs provided by a time-tested mechanical design, we can leave the finer details and features to the software side. This is where the highly honed control software and the development that has gone into it steps in. Not only does this approach enable us to provide a variety of features, and different ride characteristics, but also the ability to implement them very quickly, and efficiently. 

More often than not, it’s easier and faster to develop new code than to replace hardware. 

Time-tested Drivetrain Solution

Even though the current bicycle drivetrain is a respectable piece of engineering, it’s far from ideal or not to mention a pinnacle of drivetrain technology. Fragile parts, components that are subjected to high wear rates, and the need for regular maintenance are some of the most obvious shortcomings of current systems.

The Revonte ONE Drive System employs a highly reliable, and simple single-speed transmission. One chain paired to a pair of sprockets – could not get much more simple than that! With simplicity,  the benefits of lower maintenance needs, very affordable spare parts, and overall robust construction are realized.  

How would this look if it was simple? This is a question often raised in engineering. Our answer to the question is that the drivetrain should include as few parts as possible that are subjected to the elements, and thus oftentimes high wear rates.

The single-speed transmission has stood the test of time for more than a century, and it is safe to assume that it’s not going anywhere anytime soon. 

It is worth noting that the long list of benefits also include the option for using a belt drive which is virtually maintenance-free, and the most “tidy” option available since it does not require any lubrication for proper functioning.

Fully Connected

The future of e-bikes will be focused more and more on the overall ride experience. Not only has the nature and performance of the assistance to be top-notch, but also other features found on the drive system, including connectivity to other devices. We’ve made sure that the Revonte ONE Drive System is future-proof by including a full set of connectivity technology inbuilt on the drive unit itself. The list includes Bluetooth, 4G, and GPS. 

The versatile, and fast connectivity options enable software updates over the air, as well as connecting 3rd party applications if the need arises. In other words, we’ve left all the doors open for future development by embedding all the modern connection standards to the drive unit. This also means that we are not tied to a specific layout or standard, nor are there other limiting dependencies 

In Closing

By leveraging the features of the mechanical design, pairing that with highly sophisticated control software, and full connectivity we are able to deliver something very special to the world of e-bikes.

“One hardware, all types of e-bikes”, is the motto of the Revonte ONE Drive System which can be realized with ingenious design work, and picking the best features from a varied field of technologies, including mechanical, software, and electronic engineering. 

Combining all these factors we can say that Revonte ONE Drive System will retain its modern status for many years to come, and provide a ride experience that all other drive systems are compared to. 

More than Just Bikes – Why E-bikes with the Revonte ONE Drive System Are a Category Breaker

E-bike sales have rocketed during the past years which in turn is clearly reflected in the scenes of some of the biggest cities in the world, especially in Europe. E-bikes have quickly arisen to the position of a default vehicle for a variety of types of use.

Read further why e-bikes are more than just bikes equipped with an electric motor, and what type of role the Revonte ONE Drive System plays in this picture.

For Everyday Use

E-bikes are a vehicle and a means for transportation for everyday use. This has been the case with traditional bicycles already in certain parts of the world, but the assistance provided by the electrical motor takes the potential of this splendid vehicle to whole another level. With the aid of the electrical motor, one can ride further, longer, faster, and transport goods with ease. Before, all these tasks were reserved for the automobile, but times have changed and for several reasons.

When developing the Revonte ONE Drive System the following criteria were considered throughout the process to guide every engineering decision on the way, whether it was mechanics, electronics, or software-related. 

·      Ease of use. The use of the e-bike should be intuitive, nearly laughable easy. If one can ride a bike, then one should be able to use an e-bike equipped with Revonte ONE Drive System without any instructions. This is where the automatic & stepless feature of the drive system plays an essential role – just pedal, the drive system will take care of the rest, providing the correct gear ratio for every situation.

·      Low maintenance. It’s certainly nice to have every feature and trick in the book, but it matters very little if the hours used for riding and servicing have nearly a ratio of 1:1 or even worse. Thanks to the robust design and construction of the Revonte ONE Drive Unit, and the tried and true single-speed drivetrain arrangement, our drive system needs very little servicing and maintenance. When paired with a belt drive, even the occasional lubing of the chain can be left out! 

·      Up to date. When purchasing a bike with the Revone ONE Drive System, one is not only getting the state-of-the-art drive system, but it’s also going to stay that way for a long time to come, thanks for the continuous software updates which can be done over the 4G network via the inbuilt connection found on the drive unit.

More than just a Bike with a Motor 

It is still common that e-bikes are considered “just” bicycles with motors bolted on them. While this is true on the most basic level, the potential of this powerful combination is way, way higher.

In a recent story in Helsingin Sanomat Visio – the largest magazine in Finland – our CEO Otto Chrons summarized the potential of e-bikes and the role this technology is going to play in the near future nicely. 

“From the beginning, the main idea was to make the electric bike a worthy competitor to the car.”

-Otto Chrons, CEO of Revonte

This holds especially true with e-bikes using the Revonte ONE Drive System for the reasons stated earlier. E-bikes provide a convenient, easy, and environment-friendly way to commute. This has been the trajectory in countries with especially strong cycling culture, like in the Netherlands for example. The rest of Europe is following suit, as is most of the developed world.

Besides commuting and simply being a means of getting around, e-bikes are also the answer to the last mile dilemma in the professional transportation sector. City centers are getting more and more crowded, which makes it even more difficult for trucks, and delivery vans to navigate in the close-quarters environment. Cargo e-bikes provide the answer to this timely problem! Our partner EAV from the UK is a pioneer in this rapidly growing sector and changing how cargo is being transported in urban areas. 

The Health Benefits

One common misconception is that e-bikes are for lazy people. If the said individual chooses a car or an e-bike, it’s quite clear which option is better from a health and environmental standpoint. 

It’s been observed that e-bikes lower the threshold of getting on a bike, whether it is done in the form of commuting or recreationally. Besides this, e-bike users ride their bikes more frequently and for longer distances on average.

In this light, it can be said that e-bikes can act as a catalyst of getting people moving more frequently, and thus act as a medium for people in receiving their daily dose of exercise which has a major positive effect on the long-term. 

In Closing

Thanks to its ease of use and unprecedented ride experience, the Revonte ONE Drive System will change how e-bikes are used and thought of.

Whether it’s a daily commute, moving goods in a professional setting on a cargo e-bike, or just enjoying oneself in the saddle, the Revonte ONE Drive System will tick all the boxes.

The one drive system to rule them all.

On Testing

When it comes to developing a high-end product with a wide spectrum of features that combines technologies from a variety of fields like in the Revonte ONE Drive System, testing is paramount. In this article, we’ll provide an insight into what goes into developing and testing the smartest e-bike drive system out there.

Multiple Phases

Designing an e-bike drive system like the Revonte ONE is a task that requires a lot of engineering from several different departments; mechanical, software, and electrical are the main ones.

To verify that the design fulfills its intended purpose, testing needs to be done. The more detailed and systematic the testing procedure is, the better. This is to ensure that the drive system functions as it is designed, but also to minimize the risk of any unwanted events like error modes, or mechanical failures. As it is said, no stone should be left unturned when it comes to testing. 

Testing takes place in several phases and in different phases, from lab to real-world conditions. This is to ensure that the component or feature works as intended independently and later as an integral part of the system in varying conditions.

In the Lab

The plentiful torque and peak power output of the Revonte ONE Drive System aren’t taken from thin air. A dedicated testing rig was developed to test that the drive unit’s calculated and actual performance metrics match. The tireless test rig has put out watts more than a grand tour contender during a Grand Tour race to hone the function of the drive system.


Even though the drive unit is the heart of the Revonte ONE Drive System (and software is the brains), no part of the system gets overlooked. All the components have gone through several testing protocols to ensure that they operate as intended. Testing for things like durability against vibration, water, and moisture resistance for IPX6 grading are just a few found on the long list. 

Something as simple as being able to withstand the stress that the parts are subjected to under several years of use. For example, the paddles of our Controller was tested for the number of presses that would take place during a 2-year time period on average – and that’s a lot of clicks. 

In the Field

Field testing follows next. Even though a lot can be done in the lab, there’s no substitute for real-world testing. Subjecting the components to the outside elements during prolonged use, leaving the bike unwashed for a period of time, riding in the pouring rain, tackling the steepest uphill one can find, or just simply pushing the paddles of the Controller with a bit more force than intended pose demands to the drive system that can not be replicated in the lab environment.

Hence, we’ve put the Revonte ONE Drive System through its paces in the field to reveal any hidden or unknown issue that had escaped the thorough trials so far. 

A Straightforward Goal

The goal of all of this is straightforward: to deliver the smartest e-bike drive system which delivers what it promises and keeps on doing that for a long time to come. 

For those eagerly waiting for the release of the Revonte ONE Drive System, we can, fortunately, say that the end is near, and the result is worth the wait.

Eurobike 2021 Wrap-Up and Moving Forward

Eurobike is the premier annual show which showcases the new products for the upcoming year as well as showcasing new technologies and developments which are about to be employed in the market in the near future. In short, the annual show organized in Friedrichschafen Germany shows who’s who by calling every major player to show their hand for the upcoming year. 

Making an Impact

Eurobike was a big midterm goal for us. First, we wanted to present all the hard work and development that has gone into the Revonte ONE Drive System since our last appearance in the show in 2019. Back then, we did not have a rideable prototype with us – something that was going to change for 2021. 

The testing and development have been ongoing and even fierce. At any given time we’ve had rideable prototypes around the office, but we wanted to make sure that the version that was coming with us to Eurobike would be pristine in its performance. The current supply chain issues and material shortages have not played any favours on this front, but we made it happen. 

It goes without saying that there was no shortage in demand when it came to test ride slots. There were almost no idle moments when the bike was on the move, whether ridden by our future potential customers or media personnel.

In Partnership

We partnered with our longtime collaborators EAV and Lavelle bikes to have a strong presence in the show. Our booth stood out with its central location, ample footprint, and timeless black and white color theme. The bikes from EAV and Lavelle were the icing on the cake, displaying the versatility of the Revonte ONE Drive System. 

The futuristic and highly refined model from Lavelle Bikes was an eye-catcher to say the least. The shapes and highly engineered carbon lay-ups of the frame are a work of art by themselves as is the asymmetrical design which is enabled by the Revonte ONE Drive System.

The EAV 2Cubed cargo e-bike had just as strong of a stand in the show. Leo from EAV had no dull moment during the entire four days of the show in describing the features of the vehicle and the design philosophy behind it. 

Moving Forward

Eurobike produced more than anticipated interest towards the Revonte ONE Drive System. When it comes to e-bike drive systems, combining the motor and the transmission all in one enclosed unit is the way of the future, and has been our solution from the start.

Currently, we are finalizing the mechanical design, testing, and stress-proofing the production methods and moving into the production phase in 2022. The start will be done on a smaller scale to ensure the highest level of quality control. Once the production processes have been verified and thoroughly tested, we’ll be moving into mass production in the 2nd stage. 

Bikes equipped with the Revonte ONE Drive System will be available in 2022. If you want to be among the first lucky ones enjoying the automatic & stepless operation of our drive system, stay tuned for future updates on specific bike models.

In case your German language skills are a bit out of touch, a translated version provided by Google can be read here. A summary of the test ride is found below.

“The full assistance mode topped it off so that there was an abundance of power available! You notice this when you accelerate quickly, which happens still really quietly. Only the gear changes were a bit rougher, but this will be brought to an optimal level in the course of the development of Revonte.

Overall, the system has already made a good impression on us and we can expect a unique drive system for the series variant, which does not have any susceptible derailleur gears.”

What Makes a Good E-bike Drive System – And How We’ve Met the Demanding List of Criteria

Even though the e-bike industry can be considered quite young, a considerable amount of maturation has taken place in just a couple of years. Gone are the days when a bike manufacturer can bolt a motor around the bottom bracket, place a battery on top of the pannier rack and call it an e-bike.  Besides more polished looks the assistance behaviour has improved by leaps and bounds – and the Revonte ONE Drive System is going to take it to the next level. 

Read further to learn more.

Ride Experience

When it comes to evaluating drive system performance, assistance behaviour rules the game. No matter how nice looking, light or easy to use the system is, it does not matter if the ride experience resembles that of a cheap scooter that gas water mixed in the gas tank. 

We’ve taken great care in developing the assistance behaviour of the Revonte ONE Drive System to the extent that it feels as if the bike is thinking already one step ahead. How is this accomplished you might ask? By refining the software with the aid of continuous and prolonged testing and by using high-quality sensors to detect even the smallest actions performed by the rider. 

A close second to the assistance behaviour is the ease of use. Conveniently the Revonte ONE Drive System scores the very top on this department, thanks to its automatic & stepless transmission. Just pedal – the bike will take care of the rest! 

Configurability – on more than one level 

It is already commonplace that a drive system has some level of inbuilt configurability by offering the choice between different assistance modes and possibly even more detailed settings. With the Revonte ONE Drive System, we’ve taken the configurability aspect to the next level. 

First, the bike manufacturer can configure the drive system according to their needs, whether it’s a commuter bike or a heavy-duty cargo e-bike. After the initial specs the end-user – meaning the rider – can configure the drive system according to their wishes or needs via our dedicated app. 

Inbuilt Modularity

What makes the Revonte ONE Drive System truly unique is that a single drive unit can be used in all types of bikes from a high-performance e-mtb to a commuter designed year-round daily use. From a bike manufacturer’s perspective, this is a very welcomed feature since it lessens the needed design considerations, product variants and stock overhead. 

And that’s not all. The Revonte AKKU is the smartest e-bike battery out there for a good reason. Both AKKU 5 and AKKU 7 share the same form factor, i.e., they have the same physical dimensions, hence making them interchangeable. This enables the bike manufacturer, or the rider, to spec his or her bike with just the right amount of energy storage capacity. 

The various inbuilt modular features make the Revonte ONE Drive System the ultimate choice both from bike manufacturers, but also from rider’s perspective.

Reliability

When it comes to power transmission, the century-old chain is still looking for a worthy rival. With the Revonte ONE Drive System, one can use a wide single-speed chain which is the most robust and durable type there is. Add to that the fact that the ingenious design of the Revonte ONE Drive Unit makes damage-prone derailleur obsolete, the reliability factor gets multiplied. 

As a nice bonus replacing the whole drivetrain costs only a fraction of that compared to a set consisting of a complex cassette, multi-speed chain and compatible chainring. 

Up to Date

Nobody likes to ride an old bike, especially if a newer or better model is available. There is no way to stop the ongoing technological development – which is only a good thing – but we’ve done everything in our power to keep Revonte ONE Drive System up to date and performing at its best for as long as possible.

How can this be done once the bike has left the factory floor then? By software updates which can be made swiftly and effortlessly, thanks to the inbuilt 4G connection which is a default feature in the Revonte ONE Drive System. 

In Closing

An e-bike drive system has to tick a lot of boxes to be a top performer in all areas. Revonte ONE Drive System does this with flying colours and goes even beyond that. The automatic & stepless transmission and the simple construction of the drivetrain itself take the e-bike ride experience and ease of use to an unprecedented level.

The one and truly smart drive system out there – Revonte ONE.

Lessons from the Industry

The bicycle drivetrain started as a direct mount application where the pedals were attached directly to the hub. The use of a chain in the form of a single-speed drivetrain was the next phase of evolution. The possibility of changing gears rapidly while riding followed next with the aid of a derailleur. This is the phase we are now still, but this needs to change.

E-bikes create a whole new set of requirements for the drivetrain – which the Revonte ONE Drive System solves brilliantly. Read further to learn why that is.

A Brief Primer

The addition of electric assistance to the drivetrain creates a whole new set of design conditions and demands. When it comes to e-bikes, the technology used in traditional bike can’t be fully adopted – or not at least with the assumption that the performance will be flawless across the board. 

When it comes to other components, such as the frame, cockpit parts, suspension and even brakes, the current technology serves us well when it’s adopted e-bike applications. The drivetrain, however, is of special interest in this case. 

The addition of electrical assistance with the need for fast, reliable and shifting creates a whole new situation that hasn’t existed before the era of e-bikes. This leads us to the topic of loads. 

Low and High-Loads

The traditional bicycle drivetrain can be defined as a mechanism that’s subjected to low-loads, at least with the majority of use cases. A strong rider can without a doubt apply a respectable amount of torque and power to the pedals, but when compared to figures seen in industrial applications the numbers are meagre at best.

This makes the bicycle drivetrain a low-load application which the technology used so far has been able to cope with. 

The situation changes, however, when a powerful e-bike motor is added to the equation. In practical terms, it can double the torque and output that the drivetrain components are subjected to. Now we move on to the high-load territory. When talking about demanding applications like cargo e-bikes, this matter gets even more pronounced. 

A chain can handle loads like this without a problem, but the same can’t be said about the entirety of the drivetrain. As it’s often said, a chain is only as strong as its weakest link. Interestingly, the chain isn’t necessarily the weakest link in this scenario, but how it’s used. A chain will do its task diligently, but moving it sideways from one cog to the next under tension creates a set of problems – as most e-bike enthusiasts have surely noted.

Things That Used to Matter

Historically cyclists have been nearly obsessed with weight which has led to the use of “materials” such as drillium. When not taken to the extreme, making bikes and other human-powered vehicles responsibly light makes sense. The power to weight ratio does matter somewhat, whether one likes it or not. 

With the advent of e-bikes, the set of circumstances and limiting factors we are dealing with are quite different! First of all, when the assistance of the drive unit is added to the equation, the weight of the bike becomes almost a non-issue. Trying to make e-bikes as light as possible in exchange for performance and/or durability is an exercise in futility. 

The same line of thinking applies to efficiency. With traditional bikes, efficiency is best kept in the high 90’s or so, but with e-bikes, one gets a lot more leeway when the drive unit is churning with steady assistance of 250W – an output that will take a considerable amount of training to sustain for hours on end.  

Tried and True Solutions

Traditional bicycle drivetrains tick the boxes somewhat well when it comes to efficiency and low-weight. When it comes to e-bikes, these criteria become nearly marginal. Instead, reliability, robustness, easy shifting and low maintenance are things that are wanted.

A quick look outside of the bicycle industry gives obvious clues of the direction of what a winning drivetrain would look like. When it comes to automotive, industrial or even motorcycle applications, in none of these (or very rarely at least) you see a chain or a belt transferred from one cog to the next. Instead, gearboxes and other similar robust and oftentimes enclosed systems are more than prevalent. 

When it comes to e-bikes, we can do better than what’s available currently. This is where Revonte ONE Drive System steps in; a robust, reliable and low maintenance transmission. And we haven’t even mentioned the automatic stepless gearing feature which will provide an unprecedented ride-experience

In Summary

Until now bicycles have been optimized around weight and efficiency. Although still somewhat important, they are far from the top of the criteria list when it comes to e-bike applications. Traditional bicycles are in the low-load category when it comes to drivetrain characteristics. In the case of e-bikes, we are moving significantly closer to the high-load territory and its accompanying design conditions. 

This simple characterisation should be taken into account in the design of the whole drivetrain, and that’s what we are doing with the Revonte ONE Drive System while also improving the ride-experience significantly; just pedal and the bike will do the rest!

This simple characterisation should be taken into account in the design of the whole drivetrain, and that’s what we are doing with the Revonte ONE Drive System. It’s more than capable of handling the high demands of a modern e-bike power transmission while also improving reliability and last but not least, the ride-experience itself; just pedal and the bike will do the rest!
