Flux Performance Announces New Electric Motocross Bike


At the recent Los Angeles Supermotocross Finals, I ran into an old friend in the pits. Bill Weppner was an engineer at Honda US when I met him years ago, but he was anxious to share the news with me about his new position at Flux Performance, a company based in Western Slovenija. “We’re working on a new electric motocross bike that is gonna blow everything out of the water,” Weppner said. Bill introduced me to Marko Ukota, the CEO and Co-Founder of Flux Performance. They showed me several photos and video clips on their iPhone and said that news would be released soon. Impressed with what I had seen and open-minded to all forms of two-wheeled off-roading, I have kept a close eye on my e-mail inbox ever since. Today, news of the Flux Performance Primo finally dropped!

Battery Pack

At the heart of the Flux Primo is a 450V 7kWh battery pack that sets new standards in energy density and performance. To control the heat, each cell has a direct thermal connection to the case. All of the 432 cells are connected with an ultrasonically welded wire that acts as an individual fuse and are controlled by Flux’s own advanced battery management system. It’s possible to extract the battery from the right side of the bike and replace it with a fully charged one.


The water-cooled electric motor delivers instant torque and more power than gas bikes. But what sets the Primo apart is its digital control system. With personalized power and throttle response, this bike is easy to ride for experts and beginners alike.


The vehicle control unit takes in data from sensors like g-forces, lean angles, and wheel speeds to help develop algorithms that improve rider safety and performance. With a software-defined approach, it’s possible to control every aspect of the bike with code, opening up a new world of possibilities. Virtual clutch/regen brake: What makes the Primo extra special is its digital lever. Functioning as a virtual clutch, it mimics the function of a standard clutch to help you in those critical moments. It also doubles as an electronic regen brake that charges the battery without using brake pads. With digital control, riders can customize them to behave however they like. Marko Ukota, CEO: “We want a future where we ride more and enjoy true freedom, shaping it with the help of riders. We’re committed to having an honest transparent relationship and claims we can stand by. Because at the end of the day, we’re not just building a bike, we’re building a community of innovators who are changing the status quo. The Primo is our starting point, this is just the beginning” The Primo is FluxMoto’s development platform, used to test the drivetrain technology and gather ride data and user feedback.

Armed with these data points, they plan to unveil the final production motorcycle in Q4 of 2024 and start deliveries in Q4 of 2025. Three models will be available: -Motocross -Enduro (road legal) -Supermoto (road legal) You can place an early reservation on www.fluxmoto.co to get an early believer discounted price of 12.000€, as well as get the bike before your friends do (if they weren’t faster).



What do you think about electric motocross bikes? We feel that there is room for new technology in our sport, and that while we don’t see a 100% electric future, we welcome the new category with open arms and open minds. Drop a comment below!

    E-bikes are going to be a big part of our future in motocross. With electric bikes becoming available for kids, e-bikes will be the bike of choice as that generation gets older. Until the performance can be regulated, it will be a while till we see them in AMA competition. The battery technology needs to get lighter and longer lasting too.

    Wow, as a die-hard 2-stroke guy I huffed and puffed and blew away the 4 chokes, don’t really like how they respond and see how many top writers have busted their asses because the bikes grabbed for traction when they least expected it. Only now we are having Pros coming up with written 4 jokes all their life.

    However with bikes like the Stark varg and no this flux company coming into play, I can definitely sink my teeth to the electronic Moto way. Motocross as a legendary racer AMA National racer and top Motocross Coach Gary Semics said, “Motocross is a drag race from turn to turn” and electric motors I believe will excel in that when used off road.

    On Road the increasing energy of the gasoline engine will always be king, that’s why a Tesla will smoke you from zero to 50 but from 50 to 120 your Camaro Z8 will catch back the Tesla and pass it like it’s standing still.

    As a former Cycle News journalist and columnist for the late MX East. I would LOVE TO RIDE one of these bikes and give my honest opinion. FYI, I was also a product tester for MX East and KTM NA had been testing they’re 2002 lineup via Dan Salamone.

    Hit me you guys.
    Donn, tell Ross even though I’ve been incognegro the last decade I’ve NOT forgotten him. You guys are heroes to be for different reasons. 🫶🏾🏁💪🏻

    I’m 65 and ride in the woods and looking forward to owning a bike that can’t stall, never have to kick, no oil changes, no gas/oil premix, no clutches, no pistons, no cranks and rods. no gears, go ride, come home, spray if off, put it up and plug it in and forget it. While riding my 300 XC-W Saturday I started getting seeing steam and smelling anti-freeze so I have to work on it. It is about due a piston and most of this stuff will be a thing of the past. What’s really gonna be nice is no more kicking with my bad right knee I don’t want ot get replaced. I hope they can get to the quality of the KTMs.
