Radian EXR: The Electric Enduro Going After Stark’s Weak Spot

The Dutch start-up has entered the electric enduro fight with the EXR, a road-legal 52 kW dirt bike built around swappable batteries, aimed squarely at the one issue some brands still haven’t solved: downtime on the trail.
Inside the Radian EXR
Electric dirt bikes already have all the power most riders could ever need. The problem starts when the battery dies halfway through a muddy enduro loop miles from your van. Radian’s answer is the EXR, built around a battery system that swaps in around 30 seconds flat.
The EXR puts out 70hp (52 kW), 1050Nm of torque at the wheel, and weighs a claimed 108kg (238 lbs) without the battery. It runs WP suspension, Brembo brakes, a chromoly frame, and a forged aluminium swingarm, with reverse mode, integrated storage, and planned road homologation depending on market. Pricing starts from €14,450 in Europe.
But the battery system is the headline here. Riders can choose between a full-size 6kWh pack for longer rides or a smaller lightweight option for sprint races, better flickability, and tighter terrain. Both are removable trackside, cutting out long charging breaks between loops. That’s where Stark should stand up and take notice.
Radian isn’t just building another electric bike. It’s trying to change how electric enduro is run. The EXR pushes riders and teams into a pit-stop rhythm. Ride hard, swap, go again. That's how motocross paddocks already operate, just without fuel cans and hot engines.
But that only works if the ecosystem follows. Spare packs, pricing, and how riders actually manage swaps in real conditions will decide whether this genuinely works or it's just a smart concept that looks better in a launch video than a muddy race weekend.
The Stark Varg still dominates the outright performance conversation, but Radian is betting riders care just as much about staying on the trail as peak horsepower numbers.
The BCB Take
Strong claims, but a long road ahead. And with production not expected until late 2027, there’s still a massive gap between prototype and real-world use. And then there’s cost and practicality. Spare packs, pricing, and whether riders can realistically run multiple batteries will matter just as much as the tech.
But unlike plenty of electric dirt bike launches, Radian seems laser focused on the stuff riders complain about once torque stops demanding all the attention.
Ride safe, folks.
