Bianchi Impulso E-Allroad GRX 600 Disc Electric Gravel Bike 2021
Equipped with Shimano’s gravel-specific GRX 600 groupset and wide, all-terrain Kenda Flintridge tyres, the Bianchi Impulso E-Allroad GRX 600 Disc Electric Gravel Bike is designed to open up your riding to tracks, trails and bridleways. This bike features a rugged aluminium frameset, with clean lines and distinct Bianchi styling, and is equipped with an eBikemotion X35 Plus hub motor system to help you cruise up steep climbs.
The 250Wh battery is lightweight to enhance the handling of the bike and is housed neatly in the downtube to retain the look of a traditional gravel bike. Unlike many motors, the eBikemotion X35 Plus is ultralight, with the entire system coming in at under 3.5kg. This retains the spritely handling of its non-electric siblings, and the frictionless motor system ensures it can still be pedalled without power. The iWoc One remote control is sleek and intuitive and displays key data, such as the currently selected power mode.
Built to explore, this bike’s specification is a no-nonsense list of durable componentry. The hub motor is located in the rear wheel, and the AlexRims GD24 rims are tubeless-ready for ease of upgrading. The GRX 600 11-speed drivetrain is 1x specific, which reduces the weight and boosts reliability. A host of Reparto Corse components take care of the controls, and the wide Kenda Flintridge tyres deliver confidence-inspiring grip on rougher surfaces.
