The Ef4 model is our electric road bike in aluminium, for long distance cyclists who want assistance to enjoy long distances, with a geometry that gives them the postural comfort necessary for long days of cycling.
EF4, OUR EROAD DESIGNED FOR LONG DISTANCES
The new EF4 is a road bike designed to maximise the relationship between comfort and long distance riding.
Just like our road bikes, the new EF4 combines natural behaviour, a geometry and rigidity perfectly adjusted to optimise performance. In this sense, pedalling, at low speeds, translates into powerful assistance when you need it.
Comfort and long distance riding
Agility and reactivity.
It has an optimised geometry with a low centre of gravity that generates agility and reactivity.
The wheel width of up to 32mm
The wheel width of up to 32mm allows for the installation of tyres for demanding roads.
ICR steering system
The higher head tube allows a comfortable position and has a functional and aerodynamic ICR steering system.
A powerful motor
The Polini EP3 + EVO motor is a large motor that provides assistance similar to mountain concepts.The motor has a maximum torque of 75 N/m., with a speed sensor, TORQUE sensor and cadence sensor and an IP55 waterproof rating
The battery that powers it has a capacity of 630 W/h., 17.5 Amps/Hour
The charging port is integrated into its removable battery.
Polini motor has 5 levels of assistance, allowing the cyclist to choose the power and pedalling assistance needed for each terrain and occasion. Or you can also deactivate the assistance and work on pedalling.
The Polini display has a TFT screen integrated into the TopTube frame, with a light that automatically adapts to the ambient light. In addition to being intuitive and easy to read, it accurately displays pedaling power, cadence and motor power.
It also has Bluetooth to connect to your mobile phone, so you can easily control your e-Bike.
EF4features
It combines an aluminium frame with a flexible carbon fork to absorb the irregularities of the terrain.
It has an optimised geometry with a low centre of gravity that generates agility and reactivity.
The higher head tube allows a comfortable position and has a functional and aerodynamic ICR steering system.
The wheel width of up to 32mm allows for the installation of tyres for demanding roads.
The Polini motor provides powerful assistance, when needed
Made of 6061 aluminium, with double polished welds on the tube cuts.
It has up to 3 mounts that allow it to adapt to what each cyclist wants
EF4 PERFORMANCE
The geometry of the EF4 allows for maximum comfort, taking into account its proportions between the frame tubes.
This model has a shorter reach compared to traditional racing geometries and a higher frame height - stack - compared to racing geometries.
This combination of reach and stack allows us to have a comfortable position and a harmonious, well-proportioned, balanced and more aerodynamic appearance than a traditional endurance bike.
