Orbea Gain D40 e-bike Review 2019

Coming from one of the oldest bike manufacturers in Europe, Orbea Gain D40 is an road electric bike designed to enhance your ride.

What we likedThings for improvement

✅ The motor is powerful enough considering its size; it is also not too visible, making it look like a standard bike.

✅ The battery is hidden inside the frame and very discreet.

✅ This e bike can connect to your smart phone or to a smart watch if you like.

✅ Build-in start-up switch for an easy initial run, change of assistance level and battery level check-up.

⊖ The motor only provides assistance for up to 25 km/h.

⊖ There is no step-through frame available yet.

⊖ There is no headlight, rear light and pedals attached to this e bike.

It is essentially a road bike, but can also give a whole new dimension to your daily commute. Just keep in mind it’s not as comfy as a touring bike for the long rides :).

Outstanding power and energy concepts, as well as minimalist commands and app integration, are just a few of the things that makes it a winner.

  • Frame

The main thing to notice in a bike is undoubtedly its frame. Clearly, Orbea knows just how to maintain flawless road bike lines without giving a hint that it might be an electric model.

A nice thing if you want to impress a bunch of friends with your pedaling performance before revealing the secret.

Made from aluminum alloy, it comes in standard crossbar design. Unfortunately, ladies won’t have the possibility to choose a step-through electric bike like the Trek Verve + 🙁 but, luckily though, you’ll have plenty of sizes to choose from for all body frames and heights).

This bike is made to amplify, not dominate your ride, and it meets its purpose wonderfully.

The Orbea Gain ebike comes in all frame sizes from extra-small to extra-large to accommodate riders from 160cm tall to 190 cm tall.

  • Fork, Tires and Brakes

D40 Rear viewIts gravel bike sturdiness makes it ideal for weekend getaways, and you can rest assured you’ll get smooth rides on all terrains. The carbon fork combines with the shockproof bar tape and enhances comfort.

However, it comes with saddle and tires made for road. These all-season tires come mounted on lightweight alloy rims that further contribute to enhancing performance.

Exceptional braking power is given by the Shimano hydraulic disc brakes that can stop motion almost instantly. Thanks to its clearance, you can also mount a variety of tire sizes from 25c to 40c.

  • Battery

While the Orbea Gain doesn’t seem an e-bike at first glance, it does come with a battery hidden its frame. A powerful battery that is capable of providing assistance for up to 120 km.

Like it’s easy to imagine, the actual run time depends on various conditions, including your weight and type of terrain you’re riding on.

Nevertheless, you can still expect a satisfactory performance of the battery.

This e-bike model utilizes a 36V Ebikemotion InTube, which outputs 250Wh; it’s not as performing as the Bosch batteries, but it’s expandable. Tuning it up would mean investing more in an already expensive bike though.

Fully drained, the battery recharges in approximately 3 hours, which isn’t bad, but it isn’t exceptional either.

At least the quality of the battery is superlative, and you can expect it to have a long lifespan.

  • Motor Efficiency & Performance

Orbea Gain comes with a rear hub motor by Ebikemotion that complements the battery and enhances power. This innovative propulsion system is almost invisible on the bike and has little impact on the overall balance. Yet, it drives your vehicle up to 25 km/h.

What strikes about this motor is that it delivers a real bike feeling. It weighs less than 12 kg and ensures reliable assistance on flat terrains and inclines.

We particularly like the rear hub design that will let you experience drag-free pedaling when the assisted mode is turned off.

  • Controller

Another nice thing is the possibility to get power on demand. Orbea Gain D40 doesn’t come with a bulky control panel on the handlebar, but a sleek, discreet button on the tube.

Not only you’ll get a chance to mount a bike GPS if you wish, but the button lets you select from 3 assist modes, so you can get either top performance or top run time.

Hint: level of assist

When you press the button, you will see three (3) different colors flashing.

  • White: means there is no assistance.
  • Green: you have level 1 assistance.
  • Orange: level 2 of power.
  • Red: maximum level provided by the e-bike.

You’ll also be surprised how versatile this button is. You can use it to check the assist level and view the battery charge, all thanks to the innovative color codes provided by LED lighting.

Hint: button colors to check your battery

  • While: the battery level is above 75%.
  • Green: your battery is between 50 and 75% charge.
  • Orange: battery level from 25 to 50%.
  • Red: constantly flashing means the battery is bellow 10%.

Through smart connectivity, the bike also connects to a smartphone and smart-watch compatible app that enables deeper control.

The app integrates other useful features too, such as ride tracking and GPS route uploading.

Other features are:

  • Activate the bike with voice commands (if smart phone is connected through Bluetooth).
  • Turn on and off the Orbea D40.
  • Receive alerts and notifications of any deficiencies of the e-bike.
  • Enable / disable locking systems and security (if configured).

What we liked and don’t liked

So, lets have a look to what the D40 can do for you or what can be better for a nicer ride:

Orbea Gain D40 Positives

  • Built-in battery system and discreet rear hub motor.
  • Gravel bike frame and capabilities.
  • Hydraulic brakes stop the bike almost instantly and enhance safety.

Gain D40 to Improve

  • This bike is only available in a crossbar frame model but there is different sizes to choose from.
  • Even though the smartphone app can give all what you need, the use of a separate LCD controller could be a better choice considering the good quality of some of those in the market.

What to Consider Before Buying

Gain D40 front view and batteryThere are quite a few positive traits that could make you take out your wallet and buy this bad boy. Its main drawback, however, is the price.

Orbea is a Spanish brand renowned for the reliability of their bikes, so that’s a big plus. But there are other performing e-bikes out there that come with better batteries and motors and cost less than this one.

On the positive side, this is a lightweight bicycle, suitable to use on paved terrains and ideal for riding with or without assistance.

It even comes in sizes to fit all riders, and impresses with flawless aesthetics; furthermore, you can even choose from a variety of tire sizes. Just what you need if you want to customize your ride.

Final Verdict

The Orbea Gain D40 2019 is an excellent e-bike. It offers reliability and suitability to ride on road terrains, which makes it an expensive bike. In the end, whether it’s worth or not depends on your needs and preference.

If you want an e-bike that looks just like a regular one, Orbea offers a great choice. It delivers smooth rides, and you have plenty of possibilities to customize it.

However, if you’re aiming for utmost power, perhaps you should look elsewhere. Orbea Gain is designed to enhance, not dominate your ride, and it will unlikely reach the stated 25 km/h.

All in all, though, the Orbea Gain D40 e-bike is outstanding. If you aim to enhance your off-road riding experience or daily commute, we truly recommend it.

    I just bought a D50, same configuration as D40 except shift, Shimano Claris, and brakes, mechanical disk. I already used it for 300km, 5000m elevation, with and without the app. very satisfied about this product.
    on flat and downhill is very stable, brakes are ok. using the app with the heart sensor connectes it’s possible to have the motor on above a specified heart rate (I selected some 85%fc). in this way ebike can be used to avoid too much of anaeroibic exercise, whilst staying in the high range of aerobic sector. also the add on weight compared to a standard road bike, let’say +5kg, can be used as strenght improvement when motor is off. also with the app is possible to modify the power of the motor in the three levels. setting the first one, white, around 50%, i had enough battery for 1800 m elevation, using 2nd and 3rd only in the last 900 m of elevation. no way of such flexibility with Fazua based bikes. just ordered thr range extender, additional 200 wh; should be enough for 3000+ elevation.

    Hi, I bougt the D40, and I am impressed. I am 70 years old and live in Naxos, a VERY hilly island. I have been feeling that the mountains are getting to hard for me sometimes, and when I crashed with my Bianchi I decided to by an e-bike. I am a very experienced rider, been competing as young and been cycling since om roadbikes since I was 12 years old. Anyway, the bike blow my mind. I go on the eco and that is enough to take the biggest mountains with joy, I really enjoy the ride, before It was a hell of a fight to get to the top, that means that I go longer rides, upp to 50 km climbing. The bike, compared, to my Bianchi, is about 7 kg more, but the gearing is so nice, so I can easily climb without the engine, but the engine makes it funny. I dont know what I thing about the tubeless tyres, I feel they are not so smooth like the Continental 25 I had on the Bianchi, feels heavier in the corner but I will get used to it. So gearing, engine, beauty, brakes, everything is perfect for me. I would recommend this bike to a rider who is getting older and feel that its hard to always be dropped in the mountains when you go with guys that are 25 years younger. Now I can follow and they joke about me but I feel very happy and thats why I am a bikerider.

      Hi Mickhael,
      it is inspiring to read this kind of reviews from passionate e-bike riders. I actually also like the Orbea D40 and now that you are mentioning you like the Bianchi brand, they also have an e-bike line. Check this link to read the review (https://electricbikeadvisor.com/bianchi-aria-e-road-review/). Interestingly, Bianchi has a similar approach to what Orbea has developed, but there is minimal differences that would look more appealing to some riders.
