Orbea Gain M21 All Road Carbon Electric Gravel Bike
Ride further. Ride faster. Still feel every mile.
The Orbea Gain M21 isn’t about overpowering your ride – it’s about enhancing it. Designed for riders who love long days in the saddle, mixed terrain and smooth efficiency, this full-carbon electric gravel bike delivers subtle, intelligent assistance while preserving the natural feel of cycling.
With its ultra-lightweight carbon frame (builds as low as 11.3kg), the Gain feels more like a high-performance gravel bike than an e-bike. Clean lines, hidden technology and beautifully integrated components ensure nothing distracts you from the road, the gravel, or the adventure ahead.
Why the Orbea Gain is different
At the heart of the Gain is a rear hub motor that provides smooth, responsive assistance only when you need it. When you don’t, it pedals completely drag-free – so the ride always feels natural. Orbea’s Enough Energy Concept avoids bulky batteries, delivering just the right amount of power while keeping weight low and handling sharp.
Control is handled via the discreet iWoc ONE button on the top tube. A simple press powers the system on or off, changes assist levels and displays battery status via coloured LEDs. For deeper customisation, the bike connects seamlessly to a smartphone or smartwatch app, offering ride tracking, GPS routes and system tuning.
Built for gravel, road and beyond
The All Road geometry makes the Gain incredibly versatile. With clearance for up to 40c tyres, plus mounts for mudguards and a rack, it’s equally at home on fast gravel, endurance road rides or daily commuting.
