The Orbea Gain D31 is a cutting-edge ebike design that delivers the perfect ride for the open road or quick commute around town. From the hardy, Hydro Aluminum 6000 series frame to the famous Orbea tube shaping and carbon flat-mount Speed 400mm fork, this state-of-the-art road ebike is built to go the distance. Engineered to give you just “Enough Energy” for any terrain you tackle, this design showcases an Ebikemotion X35 motor for that extra push on steep ascents or long rides. The Shimano shifters provide instinctive pedal execution for a flawless and efficient performance. For uninterrupted pedal push power, an integrated internal battery ensures you’ll ride for miles and miles.

Featuring Shimano disc brakes, you’ll get meticulous stopping and responsive control at your fingertips. Showcasing clever inner cable routing with dynamic Ready GR wheels and Kenda Alluvium Tires, there’s no doubt the Gain D31 will enhance your cycling experience.
