Erik Buell-Designed FUELL Flow Now Open For Pre-Orders
Buell's next adventure is ready for take-off.
Erik Buell is a man that doesn't stay down. After two companies of his went down for one reason or another (and then one reemerged without any involvement from him), Buell has turned his attention to electric motorcycles, and his latest venture is this, the FUELL Fllow. Borrowing some of the ideas, principles, and engineering that went into Buell motorcycles, Erik also brought along some of his team from the past ventures, too. Together, they feel they have a revolutionary electric motorcycle at a very reasonable price. Read the full (long) press release below to find out more about the FUELL Fllow.

FUELL Fllow: Ride Into the Future
Following its significant validation success on Prelaunch.com, FUELL Fllow, the e-commuter of the future, designed by the legendary engineer Erik Buell, is now opening pre-orders. Leveraging his decades of experience, Erik Buell makes a stunning comeback unveiling his visionary concept of a futuristic urban e-commuter with seamlessly merging style, performance, and groundbreaking technology.
Erik Buell: Why does the World Need Fllow?
Behind this provocative question was first a lot of research and studies about the evolution of mobility, how cities will evolve in the future (becoming “smart cities”), and if 2-wheelers still had a place in the fast-paced changing environment.
Here is how Erik Buell summarized it:
“When I look to the future, there is one compelling solution for urban/suburban transportation. Well, two actually, two wheels... two wheels in a single track with green power. Whether it’s a human-pedaled bicycle, a pedal-assisted electric bicycle, or an electric motor, two wheels are the clear solutions for urban mobility.
Mass transport works to some extent, but it’s just not a pleasant experience, and it only gets you vaguely near the place you want to be. It’s also a very expensive endeavor that burdens city budgets. Sometimes these huge expensive vehicles are full and sometimes nearly empty. In either case, they keep running from point A to B at Y o’clock even though you need to get from C to D at Z o’clock.
In Europe where streets are smaller, the support and infrastructure for two-wheelers are exploding. In the US it is starting as well. In Asia, two-wheelers have always been the solution, and now the growth is in making them greener, less polluting, and less noisy. Replacing the 60 million new gasoline-powered two-wheelers sold annually with electricity creates a huge impact on quality of life.
Worldwide, the movement to change our habits is accelerating. Urban transportation should be a comfortable personal tool empowering us to better live our multitasking lives.
A well-designed two-wheeler becomes one with the rider, with speed and range far beyond the rider’s ability. Those great two-wheelers make you feel like you have superpowers!
We have to blend this feeling with the needs of today and tomorrow. So quite frankly, innovation is critical - you cannot build a new future hanging onto the old ways. New urban electric vehicles must not only feel approachable but also integrate with the digital environment and technology that is part of our society.
The world needs Fllow!
There is no argument that currently, with battery technology as it stands, gas-powered motorcycles designed and used in traditional ways seem to be a more rational choice. Yet when you take into account the growing restrictions in city centers, and you focus on the duty cycles on urban/suburban use, the relevance of new types of urban scooters and urban motorcycles makes a lot more sense. Even more so when you integrate high voltage systems into your design, to make them compatible with automotive fast charging stations already installed in those areas.
We started developing the Fllow e-moto range with looks that speak of style and sport, but the real surprise is it includes the utility that urban and suburban commuters need. We broke away from the classic motorcycle architecture – with radical new ideas and materials - to give you the acceleration of a superbike with the nimbleness of a light middleweight motorcycle.
We are designing the Fllow with a high voltage system, that allows charging in competitive times with filling a gas tank. We are doing it with a smart design that has more onboard storage than most scooters. And of course, we are integrating all the connectivity and safety technology required for an augmented ride, as for all other product classes.
I will myself be striving to develop those close and personal rides into the future, so every FUELL product not only feels familiar, like part of you but also pushes out of the past and flies you to the future!”

What FUELL is trying to achieve with Fllow
FUELL’s vision is to put freedom, technology, and emotion back into urban travel by offering riders something different, innovative, upgradeable, and attractive.
Fllow is the result of a convergence of ideas on how to create urban mobility solutions utilizing the best application for electric powertrains (low speeds, rapid acceleration, zero-emission, zero noise, short distances, denser charging infrastructures) and integrating technology for safety and connectivity.
Going into more detail, we established this functional brief and set these targets for Fllow:
Urban/suburban vehicle, re-inventing the pleasure of riding a meaningful machine in an urban environment with pollution constraints/legislation.
Comfortable, easy to ride, powerful acceleration, significant in presence, enhancing to the rider, distinctive. Unique and substantial storage capability and practicality in urban environments.
Minimalistic, utilitarian, integrated, strikingly different, and beautiful
A contemporary take on an urban e-commuter with electric powertrain constraints
Price, Range, Performance
Target price of $12,995, with at least 150 miles / 240 km range in real city traffic condition
With a quick charge as fast as a “traditional stop for gasoline”
Highway capable speed
The Fllow that is presented to you today is the fruit of months of engineering, research, and design to meet these targets. And we did it!
Engineering innovations on Fllow
Fllow is about rethinking the traditional architecture of a gas-powered 2-wheeler, taking into consideration the amazing new opportunities (and challenges!) that an electric powertrain is presenting.
Among the technical innovations, we’re introducing on Fllow:
- Axially Integrated Transverse Flux motor uniquely integrated into the rear wheel – very high torque from 0 rpm up, and lightweight (patent pending)
- Battery pack integrated into chassis – structurally forms the major part of chassis (patent pending)
- Ability to update battery packs for new technologies and upgrades
- Optimized Powertrain Integration – components located to optimize chassis handling and optimize power flow (patent pending)
- High-strength lightweight alloy castings (including magnesium)
- Advanced Braking System (patent pending) allowing to drop the rear brake pedal
Integrated chassis and powertrain management with traction/wheelie control
Let's get started with Fllow
Fllow has the luggage capacity and practicality of a large scooter but appears and handles like a mid-size motorcycle. It is nimble and agile for threading through heavy traffic, accelerates like a superbike, and is highway capable. Your dream commuter, silent and non-polluting.
Fllow has been conceived and designed as a viable urban e-commuter, with 150 miles of urban range, less than 400 lbs weight with a very low center of gravity, 10 gallons of storage, space for a passenger, and a quick charging port to use existing stations.
Building a functional 1:1 real-size Fllow concept
We first defined the target features and specs, and started designing and engineering Fllow in computers and renderings. But we felt rapidly the need to have a working concept to progress faster in the development of Fllow.
We’ve built a functional concept – meaning that it is very close visually to the production model, yet doesn’t have all the features and performance of the final version. But good enough to see Fllow “in the flesh”, to sit on it and start riding!
Building a functional concept bike of Fllow allowed us to validate many engineering designs and share practical briefs more easily with suppliers and partners.
Amazing torque, large urban range, integrated fast charge: Fllow was designed for the urban rider's needs. Practicality, with storage for a bag and a full-face helmet. The low center of gravity makes it feels extremely light and easy to ride. There is even a 15hp version to meet reduced licensing requirements.
Let’s dig together into the amazing specs of Fllow:
Advanced technology, proprietary electric wheel motor (patent pending) 750 Nm (553lb-ft)
47 hp continuous (Fllow-1S) 15 hp continouous (Fllow-1)

An urban range of 150 miles / 240 km, with a charge time of less than 30 minutes
With e-vehicles, the limitation is energy, the strength is social responsibility. Real e-vehicle plans must be built around these facts. Too much manipulation of the social image of e-motorcycles has occurred - one should actually deliver viable products.
FUELL believes it is most critical to get products out that are truly viable today, and then expand into new markets as the technologies grow.
Fllow packs 10Kwh of batteries to reach an urban range of 150 miles or 240 kilometers. Of course, riding at full speed on the motorway is not going to give you that range – but remember, Fllow was designed as an urban electric commuter, capable to go on highways, and not as a replacement for a gas-powered touring motorcycle.
Thanks to its high-voltage architecture, charging times become acceptable. On a fast charger – those used by electric cars and now widely available, the charging time is less than 30 minutes. And as you never charge 100% of the battery, but rather from 20% to 90% usually, the real charging time is around 15 minutes. Just enough to get a coffee, check emails, and be back on the road.
It gets even easier at home, where Fllow can be plugged into a wall outlet, or to a home charger.
Upgrade your Fllow over time
Fllow was designed in a modular way to evolve with technology and allow for upgradability.
The battery pack module (which contains the onboard charger, BMS, and DC-DC converter – all linked together by battery technology), the rear wheel motor, and the fast charging socket can be upgraded over time, as your requirement evolve and new technology becomes available.
As for the connected dashboard, it receives regular updates, so you always have access to the latest software version.
Made in the USA
Erik Buell and his legacy team are bringing to FUELL a unique experience in designing, setting up, and operating flexible low-cost two-wheeler assembly lines ranging from 1,000+ units/yr (EBR) to 15,000 units/yr (Buell Motorcycles)
Fllow will be assembled for production in the US, and parts and components will emphasize the US and/or western provenance. A truly “made in the USA” e-commuter!
Low part count and assembly time allow for smaller assembly facilities and a lower assembly cost. Compared to a gas-powered equivalent, Fllow has 60% fewer parts, and is assembled in 40% of the time…
The Wheel Motor – an original invention from FUELL
The wheel-motor refers to the electric motor housed in the rear wheel, specifically developed by FUELL for the Fllow, removing secondary transmission (chain or belt) while maintaining power and keeping weight acceptably low.
We knew we needed wheel designs that would work with the large-diameter electric motor technology we are considering: transverse flux. We have come up with a design that works well with this technology: the design allows a sealed housing for these large-diameter designs, but keeps everything as light as possible and allows wheel/tire changes without disturbing the motor seals. Also, a design that would prevent any wheel rim and spoke deformation from lateral and vertical loads from being transferred to the motor housings.
Because the drive motor is a large diameter, the drive torsion forces go from the rotor out to the rim, therefore the spokes from the rotor carry no torsional loads, only road loads - like the ZTL brake system physics.
Fllow is fully connected and can onboard the most advanced safety system
Fllow’s dashboard is connected to the rider’s phone, on which an app offers all practical information and functionalities:
- Ignition (also Key Fob)
- Charge level
- Alarm (if incident)
- Opening of storage, saddle, access to charging port
- Service manual and maintenance alerts
- Contact with FUELL
Additionally, Fllow can onboard the most advanced safety system, developed in partnership with iRider: a tech company bringing to market the world’s first complete safety and connectivity system for light mobility vehicles – collision warning, blind spot detection, active road navigation, and more.
FUELL Fllow is available for pre-order at a $9,995 price ($12,995 MSRP). As we exceed our targets, prices will be subject to change. To stay up-to-date with any potential price drops or special offers, please follow our official pre-order page.
