2026 Orbea Gain M20i: Electronic Precision with a Balanced Performance Focus
The Gain M20i hits a sweet spot in the range, combining Ultegra Di2 electronic shifting with the same carbon frame, carbon wheels and Mahle X20 system as the flagship model. It delivers much of the M10i’s ride quality and refinement at a more accessible level.
On the road, the M20i feels smooth, efficient and confidence-inspiring. The carbon wheels add snap under acceleration, while the electronic drivetrain keeps shifting effortless even when fatigued or climbing under assistance.
Who is it for?
Riders who want electronic shifting and a lightweight carbon wheelset, prioritising performance and ride quality over absolute top-end components.

Mahle X20 Motor
One of the lightest, most compact e-bike drive system on the market. 50Nm of nearly silent, frictionless assistance gives more than enough power for even the toughest climbs.
OMR Carbon
OMR frames add high modulus and high strength fibers to a standard layup to improve stiffness-to-weight ratios.
350Wh Downtube
You can pretty much forget about the battery capacity unless you plan on climbing more than 4000m.
Integrated Lighting
Gain is safer and more functional with head and tail lamps that announce your presence day and night. The built-in light sensor automatically switches Gain´s inbuilt lights on and off.
