Test victory for the ROTWILD R.EX

eMTB News names the R.EX 900 Ultra the best overall package


Celebrated by the community, chosen by testers: the ROTWILD R.EX continues its winning streak and secures victory in the comparative test conducted by eMTB-News.

With its unique design and outstanding performance, the R.EX embodies both qualities like no other e-mountain bike. The latest awards are impressive proof that our approach of consistently reinterpreting the all-mountain e-MTB is paying off.

At the beginning of the year, the R.EX was honored with the prestigious Design & Innovation Award 2026. Now comes the next accolade: after intensive comparative rides, the editors of eMTB-News have named the ROTWILD R.EX 900 Ultra the test winner.

Test winner in comparison of current DJI Avinox models


In a comparative test of trail-oriented e-MTBs lasting several months, the R.EX ULTRA faced the critical judgement of experienced MTB testers. The test featured the latest models with DJI Avinox motors and a clear focus on riding enjoyment in demanding terrain. And this is precisely where the assessments gave ROTWILD a clear advantage, as the testers considered the R.EX to be “a powerful all-mountain bike that can handle even rough enduro terrain.”

Tougher trails are no problem with it


When it comes to riding characteristics, the eMTB-News crew says: “Want to rock your home trails? Or go on extended tours on unknown trails or even tackle tougher trails in alpine terrain in enduro style? Go ahead, the ROTWILD R.EX 900 can easily keep up.” 


The interaction between the DJI Avinox motor and the sophisticated kinematics is also particularly highlighted, as the concept impresses the testers uphill on a variety of surfaces: "Uphill, the Avinox M1 motor provides powerful propulsion. (...) Thanks to extremely sophisticated and sensitive sensors, the motor power can be precisely controlled at all times, quickly giving the impression that the motor is literally glued to the pedal. Even under more demanding conditions such as wet, rocky forest floors, loose gravel, damp roots, or mud, traction on the rear wheel remains consistently high.

The best overall package means winning the test!


In the end, the R.EX came out on top as the best overall package in the test field. The editors at eMTB-News summed it up quite clearly in their conclusion: "With the ROTWILD R.EX 900 Ultra, the German manufacturer has a powerful e-mountain bike in its range that boasts a strong motor, a balanced frame, outstanding durability, and—making it unique on the market at present—a removable battery. Its outstanding riding characteristics, combined with the user-friendly, easy-to-remove battery and well-made frame, have earned the ROTWILD R.EX 900 Ultra the top spot in the comparison test of current e-MTBs with DJI Avinox motor systems!

It's not just the editorial team that sees it this way. The community has also recognized the R.EX: at this year's eMTB News User Awards, the bike took second place in the “Most Innovative Product” category and second place in the “EMTB of the Year” category. 


 This double recognition—from testers and riders alike—is strong and very motivating feedback for us.
