Build your dream bike

Do you have clear requirements for your bike? Do you know exactly which parts you swear by? Now there is the perfect basis for your very own e-MTB: the new ROTWILD R.X275 and R.X290 framesets. 


This is an invitation to everyone who wants to know exactly what they want—to you. Mount your favorite components on one of the lightest and most powerful carbon frames and build yourself an e-MTB that is one of a kind. 


We provide you with the complete heart of your project, with everything you need. So you can concentrate fully on the build – without any compromises.



The handcrafted R.X275 frame made from high-modulus carbon. The ultimate basis for your lightweight e-MTB and great riding fun.

Your project, your vision, your ride.

Customizing a bike offers the opportunity to create something unique. Something that bears your personal signature and offers exactly the functionality you expect from your sports equipment. Many of our loyal customers have contacted us in recent years and expressed their desire for a frameset. 

Now it's time! You can order the R.X275 and R.X290 framesets from our online shop with free shipping to your home and realize your ROTWILD dream build with attention to detail during the cold winter months.
The R.X275 ultra-light build with fully drivable parts. Total weight: 12.62 kg!

FACTS

  • Handcrafted R.X275 or R.X290 frame made from high-modulus carbon. The ultimate basis for lightweight construction and great riding pleasure.
  • FOX FLOAT Factory Shock. Precisely tailored to the frame's kinematics for optimal function.
  • Integrated RIC280 carbon handlebar-stem unit. Clean look and extra push at the touch of a button thanks to the boost button.
  • The powerful and quiet drive system. TQ HPR50 or TQ HPR60 motors are included, and the battery and wiring harness are already pre-installed – eliminating most of the installation work.

Well-designed frameset packages

The challenge with e-mountain bikes is that not all the necessary parts are freely available. We solve this problem with frameset packages for smooth assembly. These include:

  • High-quality high-modulus carbon frame including headset.
  • FOX Factory shock absorber precisely tuned to the bike's kinematics.
  • Combined carbon handlebar-stem unit including boost button for a clean look and maximum integration.
  • Pre-assembled cable harness and comprehensive mounting accessories.

The framesets come with a pre-installed battery, shock absorber, and wiring harness for easy assembly. The motor and all other parts are included.
The framesets come with detailed assembly instructions. This guarantees smooth assembly for reasonably experienced mechanics.

Scope of delivery

  • ROTWILD R.X275 or R.X290 frame 
  • FOX FLOAT Factory Air EVOL LV shock absorber (already mounted in the frame) 
  • TQ HPR50 or HPR60 motor (not assembled) 
  • TQ Intube battery 290 Wh (already mounted in the frame) 
  • Pre-assembled wiring harness (already mounted in the frame)
  • TQ-specific electrical attachments (e.g., plugs, sensor cables, covers)
  • TQ 4A charger - Boost-Button - Screws, nuts, and fasteners
  • ROTWILD RIC280 carbon handlebar-stem unit
  • Operating instructions including safety instructions
Things organized neatly: What's included with the R.X290 frameset.

Two strong foundations for individual projects

The R.X275 frameset comes with the quiet and compact TQ HPR50 motor and a permanently integrated 252 Wh battery. It is the ideal basis for building a lightweight and agile trail bike with balanced support.


The R.X290 frameset goes one step further. Here, the TQ HPR60 motor with 60 Nm torque delivers more power, powered by a 290 Wh battery. This set is the perfect basis for an enduring and powerful trail bike.

A real feast for the eyes: the R.X290 frame in Bloodfin Red

“We have noticed that, similar to the classic mountain bike sector, there is also a strong desire among e-mountain bikers to give their bikes a very personal touch.”

Jonathan Zimmermann, Head of Marketing & Communication ROTWILD

Boost Button

The Boost Button we developed is perfectly positioned on the handlebars and harmoniously integrated into the cockpit. Press it for up to 30 seconds and it will deliver up to 300 watts of maximum power. For obstacles, for sprinting out of corners, for climbs on the trail. Until you need it again. The eAssist continuously takes care of the rest.
Also included: The Boost Button is part of the concept and delivers full engine power when pressed to master steep passages or accelerate out of corners.

Cockpit included

The frameset package also includes our specially developed ROTWILD Integrated Cockpit (RIC) 280 made of carbon. It connects the handlebars directly to the stem to form a single unit. This allows for fully integrated cable routing through the head tube. This increases your mobility while riding without cables getting in the way or rattling. Be safer on the road! Using this unit also saves weight. Last but not least, the RIC ensures a clean cockpit look.
The 315g lightweight RIC280 carbon stem-handlebar combination is included and enables an extremely lightweight cockpit.
