Bianchi Impulso E-Road Ultegra Disc Electric Road Bike 2021
Combining impeccable handling and intuitive assistance, the Bianchi Impulso E-Road Ultegra Disc Electric Road Bike is your ticket to longer, more enjoyable rides. The revised aluminium frame has been redesigned to deliver a sleek, traditional aesthetic, and uses an eBikemotion motor system to inject natural-feeling power into your road rides. Housed in the rear wheel, it retains the visuals of a non-electric bike and comes in at a low weight of just 3.5kg, including the downtube mounted battery.
Free from friction, the eBikemotion X35 system allows for conventional riding when not enabled. 40Nm of torque is provided for powerful assisted climbing and is powered by a 250Wh battery for enhanced performance. The iWoc One remote control is simple and effective, allowing the rider to quickly cycle through the power options available, with setting information being displayed via an RGB LED interface.
Tried and tested, the Shimano 11-speed Ultegra groupset is a high-end offering that offers slick, crisp shifting for a premium feel. Shimano BR-R8070 brakes provide ample stopping power in all conditions, for a confident, controlled ride even on steep descents, and the wide Vittoria Zaffiro Pro V G2.0 tyres deliver exceptional grip and compliance.
