The Swiss brand Thömus also wants to benefit from the appeal of the new DJI Avinox super motor. With the Oberrider, the bike specialist is presenting an e-MTB that will be available from just 19.5 kilos. Another plus point is that the bike is extremely versatile and can be configured with a wide range of equipment and set-up options - including a high-pivot rear triangle.

With the new Oberrider, Bern-based manufacturer Thömus is launching a highly configurable e-mountainbike with the most powerful drive system on the market. The traditional Swiss brand is now also relying on the Avinox Drive System from the Chinese technology group DJI. The result is the Oberrider, a full-suspension e-MTB that combines Swiss engineering with 120 Newton metres of torque and up to 1000 watts of peak power.

The facts about the Thömus Oberrider

  • Suspension travel: 150/140 mm (SL) or 170/170 mm (ST)
  • Wheel size: either 27.5 inch or 29 inch
  • Motor DJI Avinox
  • Battery: either 600 Wh or 800 Wh, permanently installed
  • Price: from 5490 CHF
  • Availability: from April 2026
  • Weight: from 19.5 (manufacturer's specification!)
  • High-pivot rear triangle design
  • Fully configurable (components, geometry, colours)

Two bikes, one platform

The top rider is based on a carbon frame platform, which Thömus offers in two versions: The SL version (Superlight) with 150 mm suspension travel is aimed at trail-orientated riders and touring bikers looking for an agile, lightweight bike. The ST version (Supertrail) has 170 mm of suspension travel and is clearly designed for enduro use. The focus here is on difficult terrain and challenging trails.

Thömus achieves the different suspension travels via two different shock mounts (in the picture ST for Supertrail with 170 mm) and different shock travel. Bikers can also adjust the progression of the rear suspension.Photo: ThömusThömus achieves the different suspension travels via two different shock mounts (in the picture ST for Supertrail with 170 mm) and different shock travel.

Another special feature: Both variants use a high-pivot rear triangle design, which is intended to minimise pedal kickback and optimise traction. We have never seen this before from Thömus. Interesting: The concept allows extensive customisation. Riders can choose between 27.5 and 29-inch wheels, adjust the reach and steering angle in four positions and switch between two shock mounting points for varying degrees of progression at the rear.

DJI Avinox as a powerhouse

The centrepiece of the Oberrider is the Avinox Drive System from DJI (test here!). The Chinese manufacturer, known for drones and camera technology, currently has the highest-torque E-MTB system on offer with 120 Nm, which is also compact and lightweight. The batteries are available with 600 or 800 Wh and fit snugly in the frame - an advantage for weight distribution and handling. However, it is not possible to quickly remove the battery, something the Oberrider has in common with the vast majority of DJI bikes. However, there is the option of a very powerful quick charger, which is another unique selling point of the Avinox system.

Customised configuration

Thömus remains true to its philosophy: every Oberrider is custom-built in Oberried near Bern. Customers choose all the components themselves - from the suspension fork, brakes and wheels to the cockpit. There are four standard colours and various custom colours to choose from. In the lightest configuration, the bike should weigh less than 20 kilograms - an ambitious figure.

The entry-level price is 5,490 Swiss francs and delivery is planned from April 2026. Pre-orders are already possible.

BIKE Conclusion

The Oberrider is a bold step by Thömus. The combination of Swiss manufacturing quality, maximum customisation and the most powerful drive on the market sounds very promising. The high-pivot design is surprising. A detailed test will have to show whether the exclusive Swiss e-MTB delivers what the figures promise in practice.
