Ducati’s Solid State prototype, LiveWire’s S2 Corsa concept and various other speedy EVs all offer visions of the future of motorcycling through their lightning-fast charging capabilities. However, that’s hardly the only way that bikes are proving the viability of electric powertrains.

The dirt world, for instance, takes a comparatively simpler beat. Brands like KTM instead rely on removable batteries to allow for continued riding.

All the same, a Dutch startup named Radian has something on the way that’s poised to shake up the status quo. The outfit announced an all-electric moto called the EXR, and it brings a new benchmark for speed.

Quick on the draw

That being the time it takes riders to swap a drained battery with a fresh one. According to Radian, the EXR’s InfiniPack system allows for full replacement in less than 30 seconds.

For context, some brands don’t build this kind of functionality into their bikes at all. Many of those that do will proudly cite changes taking “minutes” at a time, a comparative eternity.

Mind you, Radian’s figure is also without tools. In competitive applications, the EXR would be a game-changer, but even casual and amateur riders can appreciate that kind of convenience and added simplicity. 

Moreover, Radian’s batteries promise respectable performance in addition to a user-friendly design.

According to the Dutch outfit’s claims, the included 8.6-kWh Endurance pack is good for up to seven hours or 72 miles of riding. An upcoming lightweight 5.8-kWh ‘Sprint’ option will cut the curb weight down from 275 to 250 pounds.

Promise in other ways

Beyond its various battery highlights, Radian’s EXR moto does show promise in a number of other respects.

Even if it can’t match the longest ranges, the prospect of virtually instant battery swaps keeps Radian in the race.

For instance, it features a 336-V electric motor rated for 70 horsepower and 782 lb-ft of torque. As with the competition, it eliminates the need for a traditional transmission. Instead, riders can tune the torque curve through an accompanying app. 

What’s more, Radian has developed an interchangeable Smart Storage system for the EXR’s subframe. Through various inserts, it allows riders to bring everything from tools to spares without wearing a pack. The outfit also plans to support its customization with 3D-printable files.

Rounded out by a lightweight full aluminum chassis, top-shelf KYB and Brembo components and some LED lighting, it’s made only better by the promise of future motocross and supermoto variants.

After all, between its ease of ‘fill-ups’ and its integrated storage, the EXR would excel as an urban runabout in more ways than one. I know I’d like to give it a rip once equipped with some street rubber.

Availability and pricing

Radian’s EXR is now available to reserve in the Netherlands, Belgium and Germany, with availability estimated for Q4 2027. The company has stated that a broader European market rollout is to follow, and pricing is set to start from €14,450 (~$16,770)
