Cycling Experience

The Orbea GAIN M31e 1X 20mph is an enduro road bike made of carbon with a motor that gives it a longer ride distance, which I do like in this type of road bike.

For this reason I packed my gear with the intention of riding with the Orbea GAIN M31e 1X 20mph to my side of the country town.

Having booked a hotel around my destination via IHG, I set off immediately.

The route was expected to be over 100 miles long, all mainly tarmac interspersed with some unpaved gravel roads.

Cruising on a Level Road

Once on the road, I was blown away by the agility and responsiveness of this Orbea GAIN M31e 1X 20mph.

The carbon frame felt very light and stiff, and the transfer of power from my pedals was so responsive that I could feel the bike rolling forward as fast as I pedaled.

As I cruised and rode on the smooth tarmac, the SRAM Rival XPLR eTAP AXS’s electronic shifting provided a perfect shifting experience with efficient drivetrain efficiency.

Thanks to the 700C’s large wheelset, I quickly got into an aerodynamic riding position and could feel the wind whistling across my face.

On the unpaved gravel road, the bike’s comfort was also good enough.

Carbon frame material has a certain vibration absorption ability and could help me filter jitter.

The bike was very comfortable, even if this time I had more than 1 hour of non-stop riding, there was no feeling of fatigue.

Climbing and Descending

The climbing performance of Orbea GAIN M31e 1X 20mph was what attracted me the most, because the Mahle motor hub X20, ALC motor had a constant power output, and the kinetic energy output was smooth and supple.

It maximized my climbing easier and reduced physical exertion.

Then, with the geometry of the enduro bike, when climbing, my center of gravity stayed nice and stable, allowing the bike to always have a forward impact on climbs and a faster speed on climbs.

Finally, the Orbea GAIN M31e 1X 20mph used inertia on long descents and I didn’t even need any pedaling, with a big 700C wheelset that had the ability to go downhill quickly and consistently.

When it comes to slowing down in downhill corners, the SRAM R ival eTap AXS’s hydraulic disc brakes had a reliable performance, and even with fast and continuous braking maneuvers, it maintained a good braking capacity.

It also gave me the confidence to ride safer in long downhill distances.

All in all, it is a, well, enduro e-bike that I really like, and the addition of the motor has made my climbs much easier.


The Orbea GAIN M31e 1X 20mph uses a carbon frame, which has a certain amount of deformation to absorb some of the road vibrations, making the whole riding experience more comfortable.

There are a total of (XS-XXL) 6 sizes of frames to choose from across the board, with a wide range of applicability, suitable for almost all heights of riders to choose from.

In addition, the internal cable routing design gives the frame a cleaner look and makes daily cleaning easier, while the silent cable management design and integrated handlebar set reduces the amount of noise emitted while riding.

Finally, the 35mm tire clearance gives this bike more possibilities for smooth road riding and even some gravel road.


Other Version

The Orbea GAIN M31e 1X 20mph has a lightweight carbon frame coupled with a performance Mahle motor hub X20, ALC.

But this bike has a higher-end version that uses top of the line components to realize the greater potential of this frame.

For this reason, we offer an enduro e-bike with the exact same carbon frame, but with top-of-the-line components that have even more performance for a more intense riding experience.

Orbea GAIN M10i

Orbea GAIN M10i

The Orbea GAIN M10i has a smooth and powerful power delivery with an identical internally cable routing carbon frame and an identical Mahle motor hub X20, ALC.

In the drivetrain components, it uses Shimano Dura-Ace Di2 R9250 top components, with the highest efficiency and the ultimate smooth shifting feel, electronic shifting debugging is also more simple and convenient.

As for the braking components, the hydraulic disc brakes of Shimano R9270 have the top braking feel, and the gentle pressure can bring powerful braking ability, which can reduce the speed of the bike in the longest time.

Finally, the 700C’s carbon wheelset reduces weight while allowing for a lighter feel to the pedaling, further enhancing the ride.

What we like about it

  • The drivetrain of the SRAM Rival eTap AXS has excellent efficiency, and the electronic shifting is easy to adjust.
  • Hydraulic disc brakes are for reliable braking capability, no matter how harsh the environment.
  • Excellent geometry helps maintain a more upright riding position and will be more comfortable.
  • Carbon frame design, along with an excellent motor and battery combination, makes the bike lighter in weight.
  • Maximum support of 35mm outer tire width gives the bike more possibilities to adapt to a wide range of riding surfaces.
  • Full internal cable routing design with silent cable ducting for a cleaner, fresher look and lower noise while riding.

What we don’t like about it

  • Expensive and not friendly enough for novice or budget riders.


  • Where is Orbea a bicycle brand located?

Orbea is a bicycle manufacturer based in Marabia, Spain. It is part of the Mondragon Partnership and the largest bicycle manufacturer in Spain.

  • Is this bike good for distance riding?

It has a motor to add to the mix and a battery with enough capacity to have a great range for long rides.

  • How to choose the right size?

Here we have provided you with a sizing chart, but of course this doesn’t strictly have to be followed. The best way to find the best fit is to test ride.
