"Scalpel instead of Machete" - NZZ tests the R.X275 PRO
Light and high-quality – the R.X275 PRO
The lightness of the R.X275 in terms of pure weight is evident at first glance. The clean appearance and the frame underscore this attribute. This is an impression that editor Matthias Pfannmüller and the test team confirm right from the beginning. He describes the bike as "delicate," with a "narrow silhouette without unnecessary frills." The bike wants to be "beautifully light" despite the drive, even if it comes at a cost. In return, the buyer gets a very high-quality equipment, including the full carbon frame, suspension elements, swingarm, and carbon handlebars, as well as a "first-class" matte finish.
Agile up and down the trail
The testers consistently give positive feedback on the handling. The R.X275 impresses on various terrain conditions. Steering, damping, and brakes operate "always confidently." "Overall, this bike is nicely balanced and remains absolutely stable at speeds above 60 km/h, which also speaks for its stiff frame," writes Matthias Pfannmüller. He adds, "The R.X275 is nimble enough to be used even with the e-drive turned off. The lightweight helps the bike be agile in downhill situations."
The eAssist provides sensitive and individually adjustable support
The author makes it clear that the R.X275 is an eBike. He and the other testers predominantly rode the bike "with the motor." Users familiar with eBikes with powerful motors might get the impression that the TQ HPR50 motor is defective because it operates "almost silently despite the chain," for example. It could also be due to the fact that the assistance levels Eco, Mid, and High are "on the milder side." This is partly for the sake of range and also motivates the rider in training, as the software regulating motor assistance rewards a high cadence. TQ's app allows for many customization options regarding power, support, and responsiveness. "Those who fully exploit that find it almost like dealing with a regular Pedelec," notes the author.
Quod erat demonstrandum
The testers gathered their impressions on a predefined test route of 23 km and 1,000 meters of elevation gain. They rode two setups: one with our predefined settings and another with the maximum assistance. In the factory setting, the motor holds back, and the rider is primarily engaged. The two stronger assistance levels "help," but they do not "propel forward." The editorial team identifies several configurations of settings and specifies how many watts the bike adds. With the motor power set to the maximum, it can be up to 200 watts. However, even in the strongest setting, the R.X275 "always feels [...] slightly behind human performance. It pushes but does not pull." This is an "aha moment."
For whom the R.X275 is intended
"The highlight" for the testers is the Boost Button. With this, the pilot can receive maximum electric power for up to 30 seconds even when the assistance is turned off. In the NZZ test, this amounts to 305 watts. However, the rider must be aware that "afterwards, pedaling is required again." This completes the circle, addressing the question of who the R.X275 is for. It is described as a "scalpel instead of a machete" and thus a sports device for those transitioning from non-electric bikes. It allows for longer distances and a balanced heart rate. The author identifies another extreme, people who opt for an S-Pedelec on their tours. They would supposedly be disappointed by the R.X275 or need to exert more effort. For those who carefully consider what they want when buying a mountain bike with eAssist, the R.X275 is a "revelation."
