Bianchi Impulso E-Allroad GRX 600 EP3 Disc Electric Gravel Bike 2021
With a focus on endurance riding, the Bianchi Impulso E-Allroad GRX 600 EP3 Disc Electric Gravel Bike delivers lasting comfort for mile after mile of assisted cycling. Featuring a Polini crank-based motor unit with five levels of assistance, this bike offers up to 250W of power and 70Nm of torque to effectively flatten hills and speed along the flats. A multifunction LCD highlights key metrics, while the 500Wh battery provides the capacity needed for longer, sportive style rides.
Compatible with up to a 40mm tyre width, the high-quality hydroformed aluminium frame aims to smooth out the road surface and damp vibration. Shifting is taken care of by the excellent Shimano GRX 11-speed groupset, offering smooth shifting in a durable package. The carbon Bianchi fork further reduces road buzz, and hydraulic Shimano brakes add ample stopping power for the descents, even in wet conditions.
