The R.EX CORE has a radical look. Despite the high main pivot of its four-bar linkage rear suspension, it doesn’t rely on the typical idler pulley that other high-pivot concepts use. With its side-accessible battery and integrated Pins dropper post with maximum travel, the R.EX CORE has strong selling points to stand out in the highly competitive market.
Shimano has become the biggest component manufacturer for bicycles thanks to its gear, pedal and brake components. It's clear that the Japanese want to shape the E-Bike trend from this dominant market position. With torque under the motor cover, the support is generous. Nobody needs to fear steep hills anymore. Furthermore, the power of the motor control is regulated so that the start always feels dynamic,. Fans of XXL tours will be happy with the R.EX CORE due to ist excellent range.

At a glance

The most importanten ratings of the Rotwild R.EX CORE in comparison to the competitor bikes of following categorie: (9000) .

The good Fox chassis absorbs even larger roots with the calmness of a Buddhist monk. Thanks to the solid power, the Magura brakes can be counted on in the upper class segment. With four pistons and big brake rotors, Rotwild won't take any chances in that area. Wide tires provide more grip and comfort. Rotwild tends to fit narrow tires with its #reifen_inch_breite Rotwild tires. For an Trailbike, we would prefer wider treads. At the drivetrain components and the rest of the parts, Rotwild uses good equipment. In view of the high reach value, it becomes clear: The main frame is long. However, the generous reach is compensated for by a very short stem. This way, Rotwild creates a good weight distribution between the wheels and a balanced handling. With its 22 kg, the R.EX CORE is one of the lighter E-bikes. The competition is often significantly heavier.
