Product Description


The Orbea Gain D20 is a road e-Bike that takes away any limitations at a lower price in this aluminum framed model. The small battery is held within the frame to keep the bike very light while keeping its natural road bike look and feel. Whether you are looking to take the edge off your commute, overcome physical limitations, or look add miles onto your ride in a fun and practical way the Gain D20 will have your back. A single mode button at the top of the headtube uses a simple iWoc ONE interface to control power, monitor battery, or check motor assist levels.

With your Orbea Gain, you will feel a similar experience to that of a traditional road bike. The Enough Power system assures that only what assistance is needed is provided to assure that you are not cheated of your riding experience. You will get the exact amount of extra pedaling efficiency you need for a steady ride thanks to the PAS sensor. When you are not using the pedal assist, the drive system, located at the rear hub, will not add any drag to your pedaling. Disc brakes provide easy modulation and braking power for added confidence.

The aluminum framed Gain D20 also features the same outstanding technology as its more expensive cousins. Gain allows you to use an app to monitor the status of your ride and your bike and to track your progress. On your app you will be able to access statistics such as mileage, watts, and heartrate. CAN Integration adds to the intuitive technology associated with this bike. It provides a single interface for charging, diagnosis, and attaching a backup battery rather than having to deal with a ton of messy cables.

Orbea aims to make this bike accessible to any rider in the world regardless of ability, age, or goals. On the Gain road bike, you can equip 25c or 28c tires based on your preference, but it also feature clearance for wider tires in case you want to diversify your ride. With so many cutting-edge pieces to its name, the Orbea Gain won a 2018 Design & Innovation award from experts at top cycling magazines. 

With the Orbea Gain D20, your riding experience will never be hindered again. A mechanical Shimano Ultegra 8000 groupset lowers the price while providing you with convenient shifting. This e-Bike gives you the perfect balance of an extra push without the feeling that the work is being done for you. The Orbea Gain is truly a step ahead in the world of e-Bikes, so if you want to enhance your riding experience, Gain is the way to go.
