Classic 25/45
Our classic
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.
