Orbea Gain D20 Ultegra Disc E-Road Bike 2021
When enjoying your ride is your number one priority, the Orbea Gain D20 Ultegra Disc E-Road Bike is the perfect companion. The powerful 250-watt motor kicks in when you need it to and acts to enhance your ride rather than dominate it. You'll still be riding your bike, but the addition of a little extra power through the motor in the rear wheel means you can enjoy the scenery that little bit more. And because the motor is not mounted at the chainset, you get complete disengagement when not in use.
The 248Wh battery is concealed in the downtube, making the bike's silhouette appear more like a traditional road bike. Easily check your power consumption and remaining battery life using the out-front Mahle Ebikemotion iWoc ONE remote interface. With an integrated rear light mounted in the seat post, and a 60-lumen front light mounted on the interface, you're easily spotted while out on the road.
The addition of a Shimano Ultegra R8020 groupset to this bike pushes it into the premium bracket, with reliable 11-speed shifting and super-precise hydraulic disc brakes that work equally well in any weather. The 30c Hutchinson Fusion 5 tyres provide a plush ride so you can enjoy long days in the saddle with great comfort.

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