Radon is and remains the top performer in the test of five E-All-Mountains up to 6300 euros. It's a tradition: even when the first Render was presented at the end of 2019, it was a price-performance surprise. Three years later, the bike still shines with great parts, but the geometry and rear suspension have to admit defeat to other candidates.

We tested these five all-mountain bikes up to 6300 euros:

In one fell swoop in 2019, the Bonn-based mail-order company Radon said goodbye to the classic add-on battery and integrated the then newly introduced Bosch CX motor with a 625 battery into a carbon main frame at a favourable price. A concept that is still valid today. The geometry is also very close to the original Render, even though the bike from Bonn has been available since last year with a new Bosch Smart System and a 750 instead of a 625 battery.

The Radon is sporty and firm. Active riders who want to go at high speed will feel most comfortable on the bike from the Bonn-based mail-order company. For moderate touring riders, other bikes in the test field are the better choice.Photo: Max FuchsThe Radon is sporty and firm.

Sporty and classic: the riding position on the Radon Render

The riding position on the Radon all-mountain e-bike is, to put it positively, sporty. The rather slack seat angle and the low front are reminiscent of classic touring fullys. The rider's position is clearly stretched and somewhat rear-heavy on the climbs. That's why we like to push the saddle all the way forwards on steep climbs, which at least puts a little more pressure on the front end and prevents the front wheel from rising prematurely. Unfortunately, the suspension on the Render 10.0 is the least comfortable in the test field despite the high-end shock. The short suspension travel is noticeable here and the suspension hardens a little under chain tension. Not ideal for uphill traction.

The equipment, on the other hand, is top notch. Bosch's Smart System with a large 750 battery and Kiox display, Fox Factory suspension, shock with reservoir, powerful Magura MT5 brakes, lightweight yet stable wheels from Newmen's Gravity series. With other manufacturers, you can easily put down one or two thousand more for this.

Lots of riding stability for active riders: the Render 10.0 750 downhill

In combination with the slack head angle and the good tyres, the successful spec gives the Render 10.0 some points on the descents. Unfortunately, the rear suspension with only 140 millimetres of travel can't quite keep up with the long 160 mm fork. This makes the bike a little unharmonious. A 150 mm fork would suit the bike better and also offer advantages on the climbs due to the steeper seat and head angle.

The relatively low weight of 24.3 kilograms, the low front end, the firm rear end and the good wheels give the Render a lively and sporty riding feel, but the Radon is not really manoeuvrable due to the long chainstays and long wheelbase. Unfortunately, it rattles a little on the descents, but the overall finish is good and is now in the top half of the test field. This is a clear improvement on the first E-MTBs from the Bonn-based mail-order company.

Adrian Kaether's verdict on the Radon Render 10.0 750:

The newer Radon Render with Bosch's Smart System is also a decidedly sporty bike. The rider sits more stretched out than on its competitors, the rear-heavy riding position and the firm rear triangle are somewhat special. Both downhill and uphill, the Radon has to be ridden with a lot of pressure on the front thanks to the slack steering angle. Nevertheless, it is a strong bike with a very smooth ride, especially downhill for active riders. Typical Radon: The outstanding spec. With a shorter 150 mm fork it would be even more harmonious.

EMTB judgement: 8.2 points (very good)

The EMTB judgement reflects the subjective impression of the testers, the results of the reach measurement and the laboratory tests. The EMTB judgement is independent of price. EMTB judgements: super (from 9.0), very good (from 8.0), good (from 7.0), satisfactory (from 6.0), with weaknesses (from 5.0), below insufficient.

Adrian Kaether's favourite thing to do is ride mountain bikes on bumpy enduro trails. The tech expert and bike tester knows all about Newton metres and watt hours, high and low-speed damping. As test manager at MYBIKE, Adrian also likes to think outside the box and tests cargo bikes and step-through bikes as well as the latest (e-)MTBs.
