Orbea Gain M20 Ultegra Disc E-Road Bike 2021
Offering a comfortable ride with the added benefit of 250 watts of extra power to call upon whenever you need it, the Orbea Gain M20 Ultegra Disc E-Road Bike is a superb choice. Built on a lightweight OMR monocoque carbon fibre frameset, it has an endurance geometry for a slightly more relaxed position to help you ride for long hours in comfort.
The Mahle Ebikemotion motor is built onto the rear hub, and can assist the rider up to 25km/hr, making light work of hills and headwinds. And with the battery concealed within the down tube, this Orbea Gain looks more like a standard road bike than an e-bike with no structural additions to the bottom bracket area. When disengaged, the motor is barely noticeable, allowing you to ride comfortably above the 25km/hr limit under your own steam.
With the 11-speed Shimano Ultegra R8020 groupset, you're getting crisp and reliable shifting and powerful braking performance through hydraulic disc brakes. Internal cable routing through the stem makes the cockpit cleaner and more aerodynamic, while the integrated lights are a fantastically handy finishing touch.

- The Mahle Ebikemotion X35 Plus motor is designed to improve your rides, not dominate them
