With the DEFT 10.0 750 2023, German mail order brand RADON have entered the race with their eMTB for the rough stuff.

As one of Germany’s biggest direct-to-consumer brands, RADON enter our 2023 eMTB group test with the DEFT 10.0 750, which is the most potent eMTB in their portfolio. Despite generating a whopping 170 mm of travel at the front and rear travel, RADON’s 29” e-beast is supposed to impress with playful handling on fast and rough trails. At first glance, the DEFT looks a lot like its smaller sibling, the RENDER, which combines 160/140 mm of travel, at the front and rear, respectively. In-keeping with the intended use, the DEFT relies on a beefy carbon frame with a striking cross brace, which doubles as the shock mount. Unlike the front triangle, the swingarm is made of aluminium. If the DEFT had wings, it could be easily mistaken for a stealth bomber with its discreet matt black finish with gloss highlights. In a sea of black, the golden Kashima coating of the FOX Factory suspension adds a welcome touch of colour.

Only the finest – what sets the RADON DEFT 10.0 750 apart from the competition?

The DEFT relies on a Bosch Performance Line CX motor, which churns out 85 Nm torque and draws its power from a 750 Wh Bosch PowerTube battery. When it comes to securing the battery cover, RADON take an unconventional approach, using a rubber band that hooks to two bolts on the down tube. The system looks sturdy and holds the battery securely in place, preventing it from rattling on the trail. If you tend to park your bike outside, you’ll be relieved to hear that the battery is additionally secured with a key. Moreover, RADON replaced Bosch’s finicky charging port with a clever, well-positioned proprietary system.

Smart solutions like the externally routed brake line allow RADON to cut production costs and also to put a smile on all home mechanics’ faces.

The high-quality FOX Factory suspension is complemented by a rather solid spec. If you like to plough your way back into the valley on long, steep trails, you can rely on the excellent braking performance of the MAGURA MT7 four-piston brakes, which are paired with a massive 220 mm rotor at the front and 200 mm disc at the rear. A couple of small but clever details, like the externally-routed brake line, allowed RADON to reduce production costs – and perhaps to make the life of home mechanics easier! FOX also supply the Transfer Factory dropper post. Unfortunately, this only offers 150 mm of travel in size L upwards, which could be a problem for long legged riders. The choice of tires isn’t ideal either, especially for heavy riders and mean shredders. The Germans combine a 2.6″ MAXXIS ASSEGAI at the front and 2.6” Minion DHR II at the rear, both in the hard MaxxTerra rubber compound and puncture-prone EXO+ casing. This setup doesn’t do justice to the potential of the bike, so we recommend upgrading to more robust tires with the tough DoubleDown casing and the softer MaxxGrip rubber compound at the front, which improves traction.

Not enough
The tires don’t do justice to the potential of the bike. Heavy riders and naughty shredders should upgrade to the tougher Doubledown casing on both tires, combined with the softer MaxxGrip rubber compound at the front.
The high-quality FOX Factory suspension adds an elegant touch and delivers a tremendous performance on the trail.

How does the RADON DEFT 10.0 750 fare on the trail?

Enough of numbers, how does the RADON perform on the trail? As soon as you swing your leg over the saddle, the DEFT integrates you nicely between its wheels, which, together with the intuitive handling, makes you feel at ease from the get-go. Although the weight is evenly distributed between the front and rear, the RADON requires great physical effort to spontaneously pop off ledges and feels rather sluggish on flat trails. It quickly becomes clear that the DEFT 10.0 750 feels bored on flowing trails, begging for more action. It’s only when the trails get rougher that the RADON comes to life. Here it ploughs its way through nasty rock gardens with stoic composure, inspiring huge amounts of confidence while still providing sufficient reserves for botched landings. Compared to other full-fat eMTB all rounders in this test, the RADON has slightly stiffer rear suspension, which ensures lively handling and allows you to change direction spontaneously without breaking a sweat. On technical trails, the high front end takes the edge off steep chutes and encourages you to commit to daring lines.

The RADON DEFT 10.0 750 really comes to life on rough trails, where it inspires huge amounts of confidence.

On long, flat transfer trails, the RADON places you in a comfortable, upright pedalling position. When climbing, the rear end bobs slightly but still generates decent amounts of traction. However, the high front-end tends to lift easily, requiring you to actively weight the front wheel to keep it tracking. On technical climbs, the powerful Bosch motor helps you negotiate tricky key sections. Overall, the RADON isn’t just a bunch of nice components parts but a very well-rounded overall package.

With its beefy, squared-edged frame silhouette, the RADON DEFT 10.0 750 looks like it’s ready for the toughest trails!

Who should take a closer look at the RADON DEFT 10.0 750 and who should look elsewhere?

The RADON DEFT 10.0 750 is the ideal bike for price-conscious shredders who are looking for a powerful eMTB. While it might not be as intuitive as the Orbea WILD or Yeti 160E, the DEFT’s excellent touring capabilities ensure a wide range of applications. Unfortunately, small riders will walk away empty-handed, because the RADON is only available in size M upwards. If you prefer to get your bike serviced by your LBS, you might be better off looking elsewhere. As a direct sales brand, RADON doesn’t sell their bikes in physical stores, and many shops charge extra for repairs on bikes they don’t sell. Enthusiastic home mechanics, on the other hand, might enjoy the RADON a lot!
