Filante Hybrid Shimano 105 Di2 R7170 2x12sp Mahle X20 (Wilier Hy-Ndr28ac Alloy)

The Filante Hybrid is offered in six complete builds, all centered on the same Mahle X20 system but split across Shimano and SRAM drivetrains and two wheel tiers. Shimano options run from 105 Di2 R7170 2x12 through Ultegra Di2 R8170 to Dura-Ace Di2 R9270, while SRAM Force AXS E1 2x12 appears in both alloy- and carbon-wheel configurations. That gives buyers a wide performance spread without changing the underlying frame, motor, or battery concept.

The biggest spec divider is wheel choice. Several builds use Wilier HY-NDR28AC alloy wheels, while the higher-spec versions move to Miche Kleos Hybrid 42 carbon wheels; the flagship Dura-Ace build is also listed with Miche Kleos Hybrid 42 carbon. Review coverage suggests this matters to the bike’s value equation: reviewers were notably less impressed by premium-priced builds that still used alloy wheels, while the carbon-wheel packages make more sense for riders who want to capitalize on the bike’s low-weight, high-speed brief. Across the range, the common thread is premium integration rather than bargain pricing.

Reviewers consistently describe the Filante Hybrid as one of the most convincing lightweight e-road bikes in the category because the assist feels unusually natural. BikeRadar, Opticycles and others all point to the Mahle X20’s torque- and cadence-based response as a major strength: the 250W, 55Nm rear-hub system adds help progressively rather than with the abrupt surge that can make some e-bikes feel artificial. Several testers also praised how little resistance the bike shows above the 25kph assistance limit, with Bicidastrada noting that it remains easy to hold 30-38kph on rolling roads and can even feel as though the rear hub helps preserve momentum. Long-range efficiency was another recurring positive, with one tester reporting 182km and 1,550m of climbing from the 236Wh battery under measured use.

Ride and handling impressions were similarly favorable, though with more nuance. Multiple outlets said Wilier successfully shifted the bike away from the Filante SLR’s sharper race-bike personality toward a more stable, fast-endurance feel, and Biker.sk specifically praised the bike’s control, low weight and comfort over long distances. Reviewers also highlighted front-end comfort from the integrated carbon cockpit and the bike’s ability to mute road buzz despite its aero silhouette. The main criticisms were price and, to a lesser extent, rearward weight bias. BikeRadar concluded that the bike is very impressive but undermined by cost, while Cyclonline was more direct in arguing that the rear-hub layout leaves the back end feeling heavy compared with newer mid-drive rivals. Even so, the broad consensus is that Wilier’s low overall weight and polished integration largely offset those compromises.
