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. Reviews highlight its ability to provide substantial assistance while maintaining a natural ride feel, making it ideal for extended rides and varied terrain.

Pros
  • Lightweight Mahle X20 hub drive motor for stealthy power boost

  • Natural and smooth power delivery with gradual assistance

  • Optimized geometry for balanced handling and comfort

  • Integrated front and rear lights for safety

  • Customizable options through Orbea's MyO program

Cons
  • 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 can be expensive

Key Quotes
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
BikeRadar logoBikeRadar
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.
