Building on the success of the award-winning Cento10 electric bike, Wilier has created a version based on the Filante SLR, the lightweight aero bike used by the Astana Kazakstan Pro Team.

Aimed at riders who want an electric road bike that mimics a traditional road bike as closely as possible, the Filante Hybrid is the best analog electric road bike available, rivaling the Colnago E64 and Bianchi Aria E-Road in terms of looks.

With the exception of the holes needed to charge the battery, the monocoque carbon frame has no holes and all the cables for the electric system are routed inside, along with derailleur cables and brake hoses. This level of detail extends to the novel rear through-axle, which can be removed quickly and easily without cutting the cables to the rear hub motor. The one-piece monocoque carbon handlebar shares the aerodynamic design of the Filante SLR, and the pedal assist interface is integrated into the stem rather than the top tube found on many competitors.

What sets the Filante Hybrid apart from the Bianchi Aria and others is that it does not match the geometry of the Filante SLR, but the more relaxed shape of Willières' Endurance series. But surely no one riding by you would automatically assume that you are using an electric bike. Of course, they might think again if you pass by them as the road approaches a 30% grade.

The Philante Hybrid has a slight but notable weight advantage. Willier claims that the new Mare X20 motor makes it the world's lightest pedal assist system, compared to the 3.6 kg of the X35 e-bike motor used in the Bianchi Aria E Road and Cannondale Super Six Evo Neo, and the complete system The additional weight is 3.5 kg for the entire system. Wilier claims no performance gains have been reported by supplying the same 250 watts of power assist that delivers up to 60 nm of torque

.

Wilier did not announce the bikes' overall weight, but the Bianchi Aria E-Road and Colnago E64 are reported to weigh about 12 kg; Wilier's previous performance road e-bike, the Cento10 Hybrid, at 11.7 kg, Wilier cites weight savings (and better aerodynamics) as a factor in the Filante's "substantial 8% energy savings" over the Cento10.

In addition to looks, Wilier also wants to offer riders a more traditional feel. The Philante Hybrid has sensors on the bottom bracket that measure the power produced by the pedals and automatically adjust the assist from the motor accordingly. This results in smoother pedaling, no jerking or sudden acceleration, and optimized battery consumption.

In addition to the 250 wh battery built into the downtube, an additional 185 wh battery can be added by attaching a bottle-shaped battery to the seat post. The Philante Hybrid also comes standard with a Pulsar One computer.

The models with Shimano Ultegra Di2 cost £7,736/$10,082/€9,300 and the top-of-the-line model costs £10,399/$13,552/€12,500 and comes with SRAM Red eTap AXS and Wilier HY-SLR42KC carbon wheels.
