Can the new Gain ebike live up to Orbea's 'pure road' claims?
Clever system
Lightweight
Impressive range
Superb braking
You probably don’t need the Dura-Ace Di2 version

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.

A great ride and visual control of the motor’s support level from the bars
Well specced
Head unit to control and monitor motor
Battery easy to deplete quickly
No mudguard mounts
