Intersting Concept: Orbea Rallon RS

What happens when you want to combine the versatility of a modern enduro with the ride feel of a cross-country bike? With the Rallon RS, Orbea is not introducing a classic e-MTB, but rather a concept bike that explores precisely this question. The motor is not the focus, as it is in an e-bike—it’s more a means to an end. The aim is to reinterpret the known mountain biking experience.

The key to the concept is the role of the motor. Orbea uses an extremely quiet, compact, and deliberately low-power drive with the TQ HPR40. With 40 Nm of torque and a maximum power output of 200 watts, the support remains subtle—so subtle that it doesn’t define the riding experience but rather complements it.

The motor does not replace personal effort and does not open up new uphill dimensions. It merely offsets the extra weight, travel, and rolling resistance of an enduro bike. Orbea’s goal: A bike with over 160 mm of travel should feel uphill like an unmotorized CC or downcountry bike—not faster, not lighter, but equivalent.

This brings the Rallon RS closer to a bio-MTB concept than a traditional e-bike.

Another central aspect is the consistent system integration. Suspension, motor, dropper post, and controls are not independent but communicate continuously with each other. Riding condition, cadence, speed, and seating position influence how the bike reacts – uphill and downhill.

The goal is not an automated riding experience, but a predictable, stable, and smooth bike that adapts to the rider, not the other way around. As a rider, you should have to think less and just focus on riding. This argument is familiar from the RockShox Flight Attendant Suspension, where the concept works perfectly. However, here they take it one step further. Especially downhill, the Rallon RS should feel completely like a classic enduro – without motor-induced interference, noise, or delays. The drivetrain consciously steps into the background here.

The Orbea Rallon RS doesn’t want to be an e-bike but rather a new interpretation of a classic bike. It raises the question of whether performance, efficiency, and versatility will be defined exclusively by muscle power, weight, and geometry in the future. How close the worlds of e-bikes and bio-bikes have already come is shown by our system comparison of two uncannily similar Canyon Spectrals.

Orbea doesn’t use the motor to change mountain biking but to preserve it: long climbs, technical terrain, real feedback from the trail—just without the typical drawbacks of a heavy, potent enduro. In this sense, the Rallon RS is less of an e-MTB and more of an experimental interim step in the search for new bike categories.

The Rallon RS will initially be produced in very limited numbers and is clearly intended as a concept study. The focus is not on the specific bike, but on the idea behind it. The insights from this project could potentially influence future bio-MTBs in the long run – for example, through new approaches in kinematics, integration, or efficiency thinking.

Whether this path will prevail remains to be seen. What is certain, however, is that with the Rallon RS, Orbea is not questioning the E-MTB, but the mountain bike itself. And that is what makes this concept so exciting for bio-bikers.
