Summary
The Orbea Gain is a lightweight endurance e-road bike featuring the Mahle X20 hub drive motor for smooth, natural power delivery that enhances rather than dominates the riding experience. Its geometry is optimized for balanced handling and comfort, with clearance for wider tires and integrated lights for practicality. Overall, it offers a stealthy, high-performance ride suitable for both seasoned cyclists and newcomers seeking extended range and assistance.
Lightweight Mahle X20 hub drive motor with smooth power delivery
Extended battery range with options for internal and external batteries
Optimized geometry for balanced handling and comfort
Integrated front and rear lights for safety
Customizable through Orbea's MyO program
Heavier than some high-end e-road bikes
Limited tire clearance to 35mm despite claims of up to 40mm
Firmer rear feel due to hub motor weight
Higher-end builds may have a punchy price tag
Orbea gives their versatile Gain road & gravel ebike a lighter and stealthy power boost with an upgrade to the Mahle X20 – the “lightest e-bike drive system on the market”
The Gain’s ride feel outclasses every e-road bike I’ve tested in the past
It’s intended to allow you to get out and still have a decent intensity cardio workout, but without going into the red – more like you’re just having a really good day on the bike, as opposed to feeling superhuman.

Orbea is staying true to their legacy of designing eye-catching bikes, and here they’ve created another work of art with the Gain M20i e-road bike. Orbea took many details into account when heading to the drawing board on the latest version of their e-road machine.
