Radon Deft 2025 Review

The new Radon Deft offers modern technology, a big battery, and plenty of travel at an attractive price. Is it the insider tip for budget-conscious bikers? We have thoroughly tested the Radon Deft 2025.

When it comes to equipment and features, the Radon Deft takes a pragmatic approach despite the attractive price, opting for parts that meet current standards with excellent functionality, yet never going for the top shelf.

Sram’s electronic GX Eagle Transmission has proven time and again to be reliable. Magura’s MT 7 brakes remain formidable stoppers. And the Fox Performance Elite suspension differs essentially only in the golden stanchions from the top-tier version.

Our practical test confirms that all these components perform at the top level. This means you can really shred the trail. The brakes, in particular, underscore that the bike takes the maximum allowable weight of 135 kilos seriously. Thanks to their large rotors, they remain dependable even on long alpine descents or in the bike park.

The Deft 9.0 weighs 24.5 kg in size L without pedals – not a featherweight, but well within bounds considering the equipment and the 800-Wh battery. Comparable models like the Centurion No Pogo are higher priced and heavier. The Mondraker Crafty has less travel, costs 2000 € more, and is still only about 500 grams lighter.

If you want the beefy 800 battery and want it to be removable as well, you’ll have to deal with this weight, or even slightly more. Many manufacturers therefore install the smaller 600-Wh battery from Bosch. This saves 1 kilogram of weight and brings full-power bikes under the 24-kilo mark. But it also kills the range by 25%. Those dreaming of weights around 20 kilos in the full-power sector must be aware: these are only achievable with a 600 battery and a budget of 10,000 € or more. Then you get bikes like the Orbea Rise, the Cannondale Moterra SL, or the Amflow Carbon Pro.

While the smaller Radon Render is still equipped with the Bosch CX of the 4th generation, the Deft already features the Gen 5 motor (BDU38). And while we criticized the gearbox rattling of the old Bosch motor in the Render during downhill rides, that issue is a thing of the past with this bike. The Bosch CX Gen 5 no longer has that annoying noise. We’ve also shot a special video for you, where you can check out the differences in a side-by-side comparison.

What you might hear in certain riding situations is a slight rattle from the battery’s plastic cover. However, this can be easily fixed with a small foam pad glued in place for support.

Furthermore, the Bosch CX Gen 5 is truly a benchmark when it comes to motor control. We clearly demonstrated this in our comprehensive motor test. If you’re looking to experience uphill flow, this is the right tool for the job. Even though you have to actively lean forward on steep climbs due to the high front.

The other components related to the e-bike system, like the rest of the equipment, come across as pragmatic but well thought out. The Purion 200 display is located in a protected spot and shows the necessary information. I find this position significantly better than having it on top of the handlebar grip or in front of the stem. The charging flap is made of durable plastic and closes with a magnet. However, I find the hinge a bit delicate for my taste for such an e-bike. I always prefer a recessed version of the charging port here, as it simply offers better protection against damage.

With its geometry, the 29-inch wheels, and generous travel, the Radon Deft isn’t a playful bike but rather a stable companion for rough terrain. You could also say: A true powerhouse when the going gets tough. Tight corners are possible but require active body engagement, and braking demands an early choice of lines. The braking performance, thanks to the Magura MT7s, is beyond reproach. And the rear suspension matches its character perfectly.

With 170 mm of travel front and rear, the bike offers ample reserves to handle even the roughest terrain. The rear suspension has a pleasant but not overly aggressive progression. Fans of airtime may wish for a bit more pop here. However, riders who prefer keeping their wheels on the ground benefit from a consistent level of grip throughout the entire travel. We have examined the rear suspension not only in practical testing but also on a theoretical level with a kinematics program.

What stands out is that the anti-rise value remains below 50% throughout the entire suspension travel. The low value confirms our trail experience that the brake doesn’t noticeably affect the rear suspension function. Even when the rear brake is engaged, it still provides a comfortable, secure feel. We really liked the classic four-bar rear suspension.
