Bianchi Aria E-Road Ultegra Disc Electric Road Bike

Designed to expand your road cycling horizons, the Bianchi Aria E-Road Ultegra Disc Electric Road Bike utilises the lightweight Ebikemotion X35 Plus motor and carbon aero tubing to provide an exhilarating ride experience. Offering a level of assistance for longer, more demanding rides, the Aria E-Road keeps the sensation of road riding for a natural cycling experience. The slim Ebikemotion X35 battery and rear hub motor make for a stunning frameset that keeps the aesthetic of an analogue bike, with no large tubes or unsightly motor to be seen.

The Ebikemotion X35 Plus 250W hub motor offers three levels of assistance, ECO (30%), COMFORT (60%) and POWER (100%), ensuring there is a mode for all rides and gradients. Natural-feeling assistance kicks in with every pedal-stroke, giving a feeling of strong legs as opposed to the push of a motor. A top tube mounted controller allows for mode selection, letting the level of assistance to be changed with ease. The rear hub-mounted motor is powerful enough for the steepest gradients, and the 250wh internal battery offers a high-capacity for its svelte profile.

Lightweight and durable, shifting is taken care of through the Shimano Ultegra R8000 11-speed groupset. The Shimano R8070 hydraulic disc brakes provide optimal stopping power, encouraging you to push descents with confidence. The Vision Trimax wheels are reliable and roll smoothly and are clad with Vittoria’s acclaimed Rubino tyres.
