Thömus Sliker E1 | 13.29 kg | € 8,299 | FAZUA Evation 1.0

If you’ve never heard of Thömus and you’re wondering where this electric road bike suddenly came from, you’re about to discover a whole new world: Thomas Binggeli, affectionately known as Thömu, is the brains behind the exclusive brand from Bern, Switzerland. Throughout his career, he has held leading positions with brands such as BMC and Stromer. Therefore, extensive carbon and electrical expertise aren’t new territory to him. Thömus rely on the FAZUA Evation motor for their first E-road bike and they’re the only ones in the test that managed to route all cables internally. Accordingly clean looking, the Sliker E1 comes with a glossy red paint job making it by far the most beautiful FAZUA driven bike we’ve ever seen! The spec of the Sliker E1 is based on a Shimano ULTEGRA R8050 Di2 groupset with FSA carbon cranks and 160/140 mm rotors. The fully integrated in-house cockpit consists of an aluminium stem and aero-carbon bar, which, in contrast to the FOCUS, allows Thömus to mount the FAZUA remote on the handlebar. The DT Swiss ERC 1100 carbon wheelset and the 28 mm Schwalbe Pro One tires round off the package. Our size L test bike topped out the scales at 13.29 kg, which makes it the lightest FAZUA equipped bike on test. While you’re free to configure your dream bike on the Thömus website, the build you see here will set you back € 8,299.

Perfect score
The ergonomics of the Thömus’ cockpit impressed us and the perfect integration makes it stand out from the crowd.
Close call
The clearances between frame and FAZUA system is very tight. When installing the battery-motor unit, it takes a lot of effort to lock it into place.
Attention to detail
The down tube has a double wall to improve its strength.

The Thömus Sliker E1 in review

The Thömus willingly converts pedal strokes into propulsion. Although it’s not the fastest sprinter in the test field, it knows how to play out its strengths once it’s up to speed. Above the 25 km/h threshold, the Sliker E1 benefits from the complete disengagement of the FAZUA motor and the aerodynamics of the frame and wheelset. Thus, it performs very efficiently on flat terrain – even without the support of the motor! With a pleasantly compact and central riding position, longer rides are no problem on the Thömus. You’ll also benefit from the balanced level of comfort the bike offers, though it definitely provides a performance oriented ride.

Tuning tip
work on your bike handling skills and then have fun

The tidiest and lightest bike with a FAZUA motor comes from a farm in Bern – who could have guessed. Chapeau!

While smaller vibrations are damped by the compliance of the carbon handlebar, the carbon seat post and the comparatively large-volume Schwalbe tires, larger hits are passed on to the rider. The handling is equally balanced, agile and quick to respond to the rider’s input, with the agility of the front matching the rear. Particularly experienced riders will appreciate the playful ride, but if you’re a beginner, you should take some time to familiarise yourself with the handling of the Sliker E1 before trying to push your limits.


With the Thömus Sliker E1, the Swiss brand has succeeded in delivering a coherent overall concept to the E-road bike market. The excellent integration and agile handling set the bike apart. Road bike veterans who value attention to detail and spritely handling will find an interesting choice with many configuration options in the Sliker E1. Beginners should familiarise themselves with the bike’s direct handling before trying to push the limits.
