To learn more about the brand and the products it markets, we invite you to read our dedicated article.

Introducing the Giant Reign E+

Whether you’re a bike enthusiast or a layman, it’s easy to be seduced by the harmonious, straight lines of this bike, dominated by deep black and chameleon green.

The e-TRX carbon wheels are very sensitive to the structure of the terrain. You can count on a solid handlebar for an easy grip, and a very comfortable size.

But the magic of this machine is in the SyncDrive Pro motor, and the EnergyPak battery it is equipped with. A true balance between comfort and elegance!

Features of the Giant Reign E+ 0 pro

A powerful and convenient bike

Even if you’re an avid cyclist, pedaling can be very strenuous, especially on steep hills and trails. Giant’s electric bike takes that effort out of the equation because every time you pedal, the internal system calculates how much force the SyncDrive Pro motor needs to sustain you.

That’s up to 360 percent of the force you put out, giving the bike a tremendous boost, so you can move with ease. With 170 mm of travel at the front and 160 mm at the rear, it provides exceptional control on long trips.

The geometry of the Giant Reign E+ 0 pro is adjustable thanks to a “Flip Chip” located on the upper composite linkage. A system of reversible wedges varies the geometry in two positions. The “high” and “low” positions vary the seat angle and the steering angle by +/- 0.8° and the height of the frame by +/- 10mm.

In the high position, the Reign E+ is lively and maneuverable, perfectly suited for technical terrain, and winding singletrack at slow speeds. In the low position, the Reign E+ becomes a rocket, stable and fast, it will cross any obstacle at the speed of light.

With the Giant electric bike, cycling will become an enjoyable adventure, without you feeling exhausted. This highly engineered electric mountain bike features an Energy Park Smart 625 battery that gives it up to 190 km of range. A single charge allows riders to ride up hills and down steep descents.

Autonomy of the Giant reign e+

The location of the battery in the down tube provides more stability and allows the rider to be comfortable during long rides. Thanks to the Fast Charge 6A charger, the battery reaches 80% of its charge in only 3h, 5h50 for 100% charge, and an automatic 60% charge mode to store the battery in optimal conditions.

Which is pretty fast if you are in a hurry to get back on the road. It will allow you to ride up to 190km, whether your activity is intense or ideal. Enough to make the pleasure last!

Giant Reign E+ features automatic driving

If you have a car with an automatic transmission, you may have appreciated the help provided by the automatic assist. The Giant Reign E+ 0 pro accomplishes the feat of giving the rider this mode by installing an accelerometer and an engine rotation sensor.

This is the Giant Smart Assist. It supports the cyclist by providing an automatic power supply, depending on the terrain where it is.

It’s natural, but it’s also very pleasant. Switching to Giant Smart Assist mode provides simple, intelligent assistance that even regulates the pedaling pace needed for the situation. But more than that, this mode allows the rider to focus on the trajectory and enjoy the riding experience.

The effort is smooth and gentle, almost natural: it will allow you to enjoy the landscape you are riding through, especially on a beautiful sunny day.

Light, comfortable and secure

Despite being heavier than a conventional bike, the Giant Reign E+ is not weighed down by its arsenal. The materials were chosen to make the bike smooth, dynamic and fast, so it weighs just 24.3 kg. So it can easily be stored at home, in the garage or against a wall.

Worried that you won’t find a Giant electric bike in your size? At Giant, we’ve thought of that detail, and offer our wonder in four different sizes: S, M, L, XL. No matter who the rider is, there’s sure to be something for them.

We once experienced, while cycling, that unpleasant sensation of not being seated comfortably, especially when crossing a rough terrain. The solution is to try our Giant Reign E+0 pro. Its 160mm Maestro suspension system absorbs shocks smoothly without affecting the rider.

Even the position of the saddle, frame and pedals were designed to the millimeter, giving the rider a comfortable posture while working the muscles.


In terms of equipment, Giant’s electric mountain bike has nothing to envy to other sport bikes. It comes with a RideControl ONE console: a connected tool that controls its options and lets you use the Giant Ride Control App.

This console also functions as a trip computer to record rides, display speeds or simply activate the bike’s assistance modes. It is also used to adjust technical statistics, such as navigation options, training, etc.
