Orbea Gain D50 2020 - Electric Road Bike

The Orbea Gain D50 was built to enhance your ride, not dominate it. The Enough Power and Enough Energy concepts result in an exceptionally lightweight, sportive and rideable road bike – a machine that heeds the call of the open road. Gain embraces your sweat and hard work and works in unison with your efforts to tick off the kilometres. System interfaces are modern, integrated and sleek. There are no bulky components to reduce the riding experience, distractions have been minimized so it’s just you, Gain and the hours ahead.

Mode Button - Save space on your handlebar for a GPS if you wish, or ride without clutter. Gain’s control centre is an attractive and discreet button on the top tube. With the simple iWoc ONE interface, you can power the system on or off, check motor assist level and view the remaining battery charge. Coloured LED lighting puts all the information you need right at your fingertips.
Internal Battery - The battery is one of the most noticeable components of an eBike system, so every step has been taken to find the lightest, smallest and most discreet unit. Gain’s Enough Energy concept provides you with enough battery power, not more. It eliminates the need for a bulky, high-output battery that needs to be removed from the bike.
Drive System - The heart of Gain, the rear hub motor is the key to Gain’s Enough Power concept. The sophisticated drive system provides enough smooth and reliable assistance at levels designed to enhance your ride, not dominate it. And since the motor is at the hub, you’ll experience drag-free pedalling when Gain is not providing a push.
C.a.n. Integration - Gain doesn’t require a multitude of wires, ports or accessories. The CAN (Controller Area Network) bus port provides a single interface for charging, system diagnosis or attaching the external backup battery.
PAS Sensor - Gain’s smooth and balanced assist requires an advanced sensor. Blending perfectly with our effort to create a sleek and discrete system, the cassette lock ring holds 20 magnets that are detected by the integrated dropout sensor. The system monitors your pedalling input and adjusts power accordingly.
App - A smartphone and smartwatch compatible app enable deeper control of the iWoc system used by Gain. Ride tracking, activity and GPS route uploading and other functions are available from your mobile device, making Gain an even more valuable tool.
Versatile - The new carbon frame includes the same integration features other Orbea carbon frames have, plus the complexity of also fully integrating the motor power cable and the P.A.S. sensor.
Mavic - In order to bring the best quality built, we´ve teamed up with Mavic and brought their bestsellers into the Gain family; the Aksium Elite and Cosmic Carbon wheels.
Tyre Clearance - The move to wider tires is happening everywhere, with even road racers opting for the comfort and lower rolling resistance of 25C or 28C tyres. To make Gain even more versatile it is possible to mount most 40C tyres, either with clincher or tubeless.
