Orbea Gain D40 Electric Road Bike 2023

The Orbea Gain D40 Electric Road Bike makes assisted road riding a reality for more riders than ever before. Its price makes it ideal for casual to more experienced cyclists seeking a boost, and it features many of the technologies found within the high-end models. Controllable via the Mahle iWoc ONE remote, the Mahle X35 Plus motor is contained within the rear hub, helping you cruise up any hill and providing assistance up to a maximum speed of 15.5mph / 25kph, with the Mahle 248Wh battery bringing a good range. The geometry focuses on comfort, and the carbon fork damps vibration to reduce fatigue on long rides. 

The specification blends value, functionality and performance perfectly, with Shimano Tiagra 10-speed making the shifting smooth and reliable, while mechanical disc brakes make for easy stopping in all conditions. Wide, 30c Hutchinson Fusion 5 Performance tyres are grippy, offer good puncture resistance and smooth rolling. The Fizik saddle is comfortable, as is the Orbea own-brand cockpit, and a seatpost mounted rear light and front light improve visibility to other road users.
