An enduro bike weighing 18 kilograms? That alone would not be enough to cause a stir. In fact, more and more modern downhill bikes are moving back into the weight range of classic freeriders. With an electric motor and sturdy parts, this is Orbea Rallon RS but still an achievement.
Orbea's latest litter based on the classic Rallon Enduro and can almost be mistaken for it at first glance. However, the low weight and sleek look come at a high price. The motor hardly provides any thrust, but the entry-level price for the complete bike is all the more hefty.
The abbreviation RS normally stands for pimped-up products with extra power. At Orbea, however, they mean "Rider Synergy" - in other words, the opposite. The focus should be on the rider, not the motor, according to the press release. In other words, the motor cannot be the focus.
Orbea has installed the HPR 40, which was actually developed more for racing bikes and gravel, with a maximum of 40 Nm and 200 watts of peak power. The slim down tube houses a battery with only 290 watt hours. The range can be optionally extended with the 160 watt-hour range extender for 600 euros.
The crux of the matter, however, is that the mini motor is unlikely to be of much use to heavy riders. With a realistic 200 watts of uphill power for the 80-kilo man, the motor adds perhaps another 50 per cent in continuous operation. The full 200 watts of motor power can only be called up temporarily due to derating and battery size.
The moderate power is then sufficient for somewhat brisker climbs on the forest road, but nothing more. Lighter riders will benefit a little more. However, as the motor requires high pedalling frequencies and a lot of power to release its limited power, sporty commitment is also required here.
On the other hand, TQ's mini unit weighs just 1.2 kilograms and can be integrated as slimly as possible. Orbea does without on the additional rocker and the balancing weights of the normal Rallon, But the Rallon RS looks very similar to its motorless brother.
Nice to see: Instead of just integrating the motor and battery, Orbea has put a little more thought into the concept and developed its own parts to match the bike. The proprietary remote displays the battery level in 10 per cent increments. The remote even switches to an even more precise display for the last 20 per cent of the battery with five red bars for every four per cent of battery.
In addition, the specially developed dropper post can be operated via the remote. Just like the drivetrain, it does not need a separate battery but is connected to the main battery. Orbea tops off the Rallon RS with Fox's Live Valve System in the top model. Here, even the electronic shock is integrated into the system and can access data from other components such as the motor and dropper post in order to engage the platform fully automatically if required. Whether you really need this feature with modern kinematics remains to be seen.
Unsurprisingly, the geometry of the Rallon RS is strongly orientated towards the classic Rallon. Steep seat angle, moderate steering angle and long reach. The geometry can be fine-tuned using a flip chip. For the time being, Orbea has dispensed with low-cost wheels for the special concept of the Rallon RS. There is only a team model with Fox Factory and Shimano XT and the LTD model with Live Valve suspension, XTR and even more carbon. The prices are between 11,000 and a whopping 15,000 euros.
"The Orbea Rallon RS blurs the boundaries between classic enduro and e-bike. Our guess: If you already ride an e-bike, the minimalist concept is unlikely to appeal to you. Why not a little more power à la HPR 60 with minimal additional weight? Probably because Orbea already has a versatile and lightweight e-bike in its programme with the Rise.
The Rallon RS is hardly in competition with this, but is more of a technology study and PR stunt. It shows what is possible in terms of integration and networking. Lightweight riders who pedal sportily and just want to go a little faster on boring dirt road uphills could still find the concept appealing - provided they have the necessary small change."
