With the release of the Engwe Engine X, adventurers are in for a treat. The electric bike, which is actually a “fat bike”, seems to have everything and is suitable to be the perfect hiking companion.

According to its specifications, it is ready to face extreme riding conditions thanks to its huge wheels. Neither mud, nor snow, nor sand will be able to impede it. If all this sounds very flattering, there is nothing like a test to confuse the beast. Here is our test and review of Engwe Engine X electric bike.

Engwe Engine X: construction and design

Originally a Spanish brand, Amperbike is known for its sturdy electric bikes, built for the most part for lovers of sports cycling. Aesthetically, the Engwe Engine X lives up to this reputation. Even better, it is the very first fat bike designed and marketed by Amperbike. As such, it stands out for its construction and design.

20-inch wheels

This bike is a mountain e-bike with larger than average wheels and tires, hence the name “fat bike”. Indeed, the Engwe Engine X has been equipped with two huge tires of 20 inches each, whereas the tire diameter of a classic mountain bike varies between 16 and 18 inches.

The wheels were equipped with off-road tires, which are normally less inflated than conventional tires. If a mountain bike is, in essence, a bike designed to adapt to all racing situations and environments, the fact that it has wider wheel rims and very fat tires, makes it even more versatile. It can be used as a mountain e-bike, city e-bike, forest e-bike, etc. A simple ride around the neighborhood personally won me over.

An alloy bike frame

Engwe Engine X comes with an alloy frame. It is important to know that alloy is mainly made of a metal material, usually aluminum, which is combined with other elements that improve its characteristics, such as, for example, rigidity or strength.

These elements can be zinc, copper, chromium, iron, titanium, or silicon. As a rule, less than 10% of the frame is made up of aluminum, which allows it to be the primary material. It should be noted that aluminum has only one-third the strength of steel. Alloy, on the other hand, equals steel in rigidity while retaining the exceptional properties of steel.

The fact that the Engwe Engine X frame is made of the alloy makes it heavier than an aluminum frame, but it is still much lighter than a steel frame. Alloy is therefore the optimal compromise between lightness and strength. I would also like to add that the alloy frame is rust-resistant, unlike the steel models.

Most importantly, an alloy frame is much more durable and allows the e-bike to last for many years. This becomes more interesting when you consider that this e-bike has a 3-step folding frame. The fact that it material is durable allows it to withstand multiple folding and unfolding moves that its use requires. 

Other equipment and add-ons

In addition to wheels and frame, which are the main defining features of Engwe Engine X, this electric bike has valuable equipment that also increases its practicality.

Like any modern electric bike, the e-bike is equipped with an LCD screen from which you can access ride information such as speed, battery level, or the electric assistance mode used.

It also has a headlight for night riding or riding in low-light areas. The screen is great and everything is very easy to read. That said, in direct sunlight, reading from this LCD could be challenging!

Engwe Engine X: power and autonomy

Engwe Engine X doesn’t just look good. In terms of performance, it’s a great machine as well, with a powerful engine and a high-autonomy battery.

Engine and battery

Installed on the diagonal tube of the bike frame, a box protects the heart of this electric mountain bike. The e-bike is equipped with a 250 W motor and a removable lithium-ion 48V/13Ah battery.

With this capacity, the battery allows a riding range of about 80 km (50 miles) under normal riding conditions. Charging time lasts, on average, 4 hours. The riding range depends on the assistance mode used and a number of other conditions.

Assistance mode

Engwe Engine X is equipped with 7-speed mechanical gear and two electric assistance modes.

With the “pedal assist” mode, the range would vary between 90 and 100 km (55-60 miles). With the “throttle mode”, you should be able to ride between 50 and 60 km (30-37 miles).

Brakes

For this fat tire e-bike model, Amperbike chose mechanical disc brakes both for the front and rear wheels. The front calipers are connected to the fork and the rear calipers are connected to the seat stays.

Mechanical disc brakes are more durable than V-shape brakes and are less prone to wear. Engwe Engine X is not equipped with a regenerative braking system.

For this well-built robust all-terrain e-bike, we would have expected a semi-hydraulic or hydraulic braking system with smooth progressive braking.

Engwe Engine X e-bike – main highlights 

This fat bike has everything you would expect from a machine of its kind: sturdiness, versatility, and autonomy. Clearly, there are always things that can be improved!

Robustness

The alloy makes the bike easier to assemble. When you ride a mountain bike in extreme conditions, it makes sense to know you’re riding a perfectly assembled bike.

This is also more important since the choice of alloy as the construction material of a bike has an impact on its riding qualities. It is therefore the quality of the assembly as well as the mechanical properties of this electric bike that allows it to better resist rough driving conditions.

Versatile riding

The combination of wheel size and tire quality impacts the ride in many ways. As a fat bike, Engwe Engine X offers riding comfort on even the most hostile terrain. The tires are low-pressure models, which offer better grip, allowing the electric bike to adapt to uneven roads.

The whole point of investing in such an electric bike is that it is intended for all uses, whether in the city, in the mountains, in the forest, on rocky or sandy terrain, or even on ice or snow. It becomes superfluous to invest in a gravel e-bike for your forest rides on the one hand, and in a mountain e-bike for mountain rides on the other.

Good autonomy

The fact that Engwe Engine X does not have an energy recovery system has little effect on the riding range since this e-bike already has an impressive range of up to 100km (60 miles). For an all-terrain electric bike, this is performance is remarkable.

Pros

  • Integrated and removable long-range battery
  • Powerful motor with pedal assist throttle modes
  • Foldable (in 3 simple moves)
  • Front & central suspensions
  • Very fat – 10 cm wide wheels
  • Front & rear mechanical disc brakes
  • 7-speed derailleur
  • LCD screen
  • Very practical luggage rack

Cons

  • Not easy to assemble
  • Speed limit of 25-30 km/h
  • Heavy weight
  • Braking system is a bit rough

Overall score: 8.25

Design: 7
Performance: 9

Comfort: 8
Price/quality ratio: 9

Combining the comfort of an electric bike with its off-road capabilities, Engwe Engine X has managed to bring together the best of both worlds in one bike. Its main asset remains in its wide tires. Large balloon tires mounted on sports suspensions offer e-bike riders exceptional grip, comfortable ride, and perfect traction. Generally, one of the main flaws of mountain e-bikes is their weight, making them difficult to use uphill or in urban traffic. 

Here with Engwe Engine X and its 250W motor, the electric assistance will guarantee you great comfort of use in situations usually tiring. In short, this bike will be a delight for those who like to ride across various terrains, while offering great ease of use in the city or on the road. And be careful not to brake too hard!
