Engwe Engine X: construction and design
Originally a Spanish brand, Amperbike is known for its sturdy electric bikes, built mostly for lovers of sports cycling. Aesthetically, the Engwe Engine X lives up to this reputation. It is the first fat bike designed and marketed by Amperbike. As such, it stands out for its construction and design.
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 vast tires of 20 inches each, whereas the tire diameter of a classic mountain bike varies between 16 and 18 inches.
The wheels are equipped with off-road tires, usually less inflated than conventional tires. If a mountain bike is, in essence, designed to adapt to all racing situations and environments, its wider wheel rims and very fat tires make 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 essential 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 include 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. On the other hand, alloy equals steel in rigidity while retaining the exceptional properties of steel.
The fact that the Engwe Engine X frame is made of alloy makes it heavier than an aluminum frame but much lighter than a steel frame. Alloy is, therefore, the optimal compromise between lightness and strength. Unlike the steel models, I would also like to add that the alloy frame is rust-resistant.
Most importantly, an alloy frame is much more durable, allowing the e-bike to last many years. This becomes more interesting because this e-bike has a 3-step folding frame. Its durable material 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 has an LCD screen to access ride information such as speed, battery level, or the electric assistance mode.
It also has a headlight for night riding or riding in low-light areas. The screen is excellent, and everything is effortless to read. That said, reading from this LCD could be challenging in direct sunlight!

Engwe Engine X: power and autonomy
Engwe Engine X doesn’t just look good. In terms of performance, it’s also a great machine 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 has 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 several other conditions.

Engwe Engine X has a 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).
For this fat tire e-bike model, Amperbike chose mechanical disc brakes 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 such a machine: sturdiness, versatility, and autonomy. Still, there are always things that can be improved!
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 impacts its riding qualities. Therefore, the quality of the assembly and the mechanical properties of this electric bike allow it to resist rough driving conditions better.
The wheel size and tire quality combination impact 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 provide 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, the mountains, the forest, rocky or sandy terrain, or even ice or snow. Investing 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 becomes superfluous.

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 performance is remarkable.
Combining the comfort of an electric bike with its off-road capabilities, Engwe Engine X has brought 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 challenging to use uphill or in urban traffic.
