Electric bike | How does it work?

System and location of the motor

Cortina has e-bikes with a powerful and silent hub dynamo on the front wheel that is driven by digital technology. The E-U1 powered by Bafang (43 Volt) is a sturdy modern urban bike, properly basic. Perfect for cycling to school. The E-U5, E-U4, E-Crush and the E-Roots have the Ecomo system (36 Volt) with comprehensive functionalities and options. These trendy e-bikes are perfect for doing the shopping, transporting kids or cycling through town. A brilliant alternative to public transport or a scooter! The Cortina E-Wave is the only one with a 36 Volt mid-drive by Shimano STePS. That makes this e-bike suitable for daily use, but also for long distances and climbing hills and mountains. This advanced system works on the basis of a power sensor. It responds to the power you put on the pedals, which makes the pedal movement feel completely natural.


The displays differ from e-bike to e-bike. For example, the E-U1 powered by Bafang has a simple display. The e-bikes with the Ecomo system have a more comprehensive display where you can set the support in fifteen increments. It means you can adjust your speed to the person who rides alongside you. The lighting can be switched on, service alerts can be set by the dealer and the range is represented dynamically as a percentage. It shows the battery level (indication). With the Drive button you activate the walking assistance. This makes it easier to push your e-bike out of the cellar or garage box. The buttons on the display have been made in such a way you can operate them with your gloves on. The Cortina E-Wave has three assistance levels.

Diagnosis software

The e-bikes can be diagnosed easily by the Cortina dealer. It is also possible to programme updates and to adjust the riding properties.
