Optima E50 Electric Hybrid Bike 2021

With ease of use at the forefront of its design, the Optima E50 Electric Hybrid Bike is a contemporary model developed to enhance your city and town travel. The Ebikemotion X35 Plus motor and battery are an all-new breed of lightweight system, designed to retain the look and feel of a traditional, non-electric bike. Powerful enough to assist on hills and propel you through the streets, yet light enough to provide responsive handling and be stored in an apartment - the Optima range combines the best of both worlds to be the ideal choice for a fast pace of life. 

Fully integrated into the downtube, the 248Wh battery is slim and lightweight, ensuring the Optima can be easily wheeled into the office. The X35 motor delivers its power with a natural, controlled feel, and lets you arrive at your destination sweat-free. The handlebar-mounted iWoc TRIO remote allows you to select your assistance level without removing your hands from the bar, perfect for mixed-gradient rides and has a sleek, unobtrusive design. 

Durable and low maintenance, the Shimano Acera 8-speed drivetrain is an ideal pairing to the X35 motor system, and the Shimano mechanical disc brakes provide sufficient power, even in damp conditions. The wide Kenda tyres are fast-rolling and grippy, and the Selle Royal Milo Plus saddle is comfortable for long journeys. SKS EDGE Alloy mudguards come pre-fitted to combat road spray, and a pannier rack adds versatility for commuting or shopping. Integrated into the battery, the built-in lights promote visibility for riding in low-light conditions.
