You’re unlikely to notice at first glance, but the 2019 Orbea Gain D21 is an electric gravel bike. It’s lines are aren’t any different than those of a standard bike, and it’s hardly any heavier than that of a gravel bike. Press the small button on the top tube, and you’ll find the key to what makes the Gain unique: a simple approach to the e-bike concept that places the rider and the ride itself before anything else. We think Orbea’s conceptual approach works well.

Orbea’s concept is based around a rear wheel built around a hub-motor that offers 250 W power and 40 Nm torque. This motor, the Ebikemotion X35, is powered by a 250 Wh battery integrated in the downtube. Torque is doled out with a buttery smoothness unlike most other motors around, often to the point of hardly noticing how much assistance you’re actually receiving going up a hill. Further, the rear-mounted motor is inherently drag-free when not using pedal assist, and the whole system’s low weight of eight pounds makes for an e-bike that certainly doesn’t handle with the sluggishness and heft of a traditional e-bike.

Orbea pairs this motor to what they call their iWoc ONE controller. This controller consists of a single LED-backlit that displays battery life and assist levels. Need more information? Pair your Orbea Gain to the Ebikemotion app, which shows exact battery life, power output, and even offers GPS navigation. It cuts down overall clutter around the bars, and provides all of the information one would need for most riding. Along with the bike’s interface and low weight of the combined Ebikemotion system (under 8 pounds), the Gain handles much like a standard gravel bike. Handling, even with the extra weight, is hardly different; there’s real a sense of purpose and poise to how the bike handles. It also doesn’t feel all that different than a standard bike above the bike’s 15.5 mph assist cutoff, and is offers strong performance to maintain speeds higher than 15.5 mph.

The 2019 Orbea Gain D21 pedal assist all-road bike starts with the Gain alloy frame and carbon fork, as well as the Ebikemotion X35 drive motor. This is accompanied by a SRAM Force 1 drivetrain, a Mavic Aksium Elite wheelset, Mavic Gravel 700 x 40c tires and a FSA cockpit and seatpost. Five sizes are available (XS-XL) in a Orange-Black, a Red/Grey/White, or a or a Graphite-Anthracite matte colorway.
