Classic 25/45

Model Classic in 25km/h or 45km/h

With the Classic 25/45, we offer you a top-class e-bike that impresses with performance, flexibility and pricing in its class.

Our Classic 25/45 is available in a 25 km/h and a 45 km/h version. Both models are based on the same hardware and differ only in the software used and the diameter of the front sprocket. This provides the ability to easily upgrade or downgrade after purchase, ensuring you always get the driving experience you want.

An outstanding feature of the Classic 25/45 is the price-performance ratio. In the 45km/h segment in Switzerland, it is one of the cheapest speed pedelecs. For only CHF 3390, you get an e-bike that can keep up with more expensive competitor products in terms of quality and performance.

The 25 km/h version of our Classic 25/45 is also a real powerhouse. With its 500 W motor delivering 100 Nm of torque, it is one of the most powerful city e-bikes on the market, pushing the limits of the legally permissible 500 W motors. Compared to the common 250 W engines that comply with EU standards, we as a Swiss startup offer our customers in the domestic market significantly more power.

With the Classic and Comfort models, you are well equipped if you need to tow a trailer or drive uphill. Thanks to the fast response and high torque of the mid-engine, these models are ideal for short distances under 20 km. For longer distances we recommend the Power45.

The components

/ The electric motor

500 watts of peak power support you during acceleration or when starting uphill. The engine is equipped with a torque sensor that measures the rider’s force and adjusts the engine power accordingly. This gives the feeling of riding a normal bike with a lot of tailwind. Also, the engine is equipped with an idle, so you can drive without a battery without much resistance from the engine.

Innovation & Quality: The Swiss Premium eBike Classic 25/45

Our Premium eBike Classic 25/45, created by a top Swiss eBike manufacturer, excels in performance, adaptability and value for money. It is available in a 25 km/h as well as a 45 km/h variant, whereby only software and front chainring diameter differ. Thus, it allows subsequent upgrades or downgrades for a customized driving experience.

Particularly noteworthy is its excellent price-performance ratio. For only CHF 3390, you acquire an eBike in the 45 km/h category that stands out in the price competition with other speed pedelecs in Switzerland.

The 25 km/h version is just as much of a powerhouse. With 500 W motor that delivers 100 Nm of torque, it is one of the most powerful city eBikes on the market. As an innovative Swiss manufacturer, we thus offer more power than the EU-compliant 250 W motors.

For use with trailers or in mountainous areas, our Classic and Comfort models are optimal. Thanks to high responsiveness and torque of the mid-motor, they are ideal for short distances under 20 km. For longer routes we recommend the Power45.
