Momabikes Ebike E20 Pro test: a folding electric bike at a low price

Comfort and ergonomics

Unlike its cousin 28 Pro, the pricing of the Ebike 20 Pro does not leave any doubt at first glance. Its aluminum frame reveals clearly visible welds and a somewhat messy finish overall. Not good, because Momabikes tried to integrate the battery into the frame to make it smarter. The execution is unfortunately guilty of a small lag in the assembly.

For a folding bike, the E20 Pro is quite heavy. It still tips the scales at 23 kg, more than the 18 kg of a Onemile Nomad. This excess weight is partly to be placed on the back of the battery and its very large capacity, as well as the integrated office equipment, including a rear luggage compartment that is unique in this segment. The weight of the electric bike must still be taken into account when dropping it in the trunk of a car or taking it down the stairs of the subway.

Fortunately, the Momabikes Ebike 20 Pro folds easily and then only occupies a volume of 80 x 77 x 41 cm. If not the king of vibration, it remains correct. When folded, the assembly remains well maintained by a magnetic system and the E20 Pro can be moved on its wheels by holding it on the saddle.

Unfolded, the Ebike 20 Pro has a rather special geometry. Its open frame, easy to ride, is suitable for cyclists from 1.55 to 1.90 m. However, people under 1.75 m may struggle to find a comfortable posture because the distance between the saddle and the handlebars is large. This requires a forward posture that is not in line with the steering wheel and the rest of the geometry.

The handle offers satisfactory comfort with decent ergonomic grips. Its height can be adjusted, a very good thing for tall cyclists. Various levers and shifters can be placed according to individual preferences and morphology, but the control of the Shimano Tourney derailleur is not the most practical.

While most folding e-bikes don’t have a suspension fork, the Ebike 20 Pro offers one. The latter offers an unfortunately very limited movement and easily hits marked paths, such as sidewalks or speed bumps. It might be wiser to opt for wider tires than the 20-inch Panaracers at 1.75 inches wide.

The plastic fenders are of good quality. The one placed in front lacks a few centimeters to fully protect the shoes from splashing water. The rear rack is welcome if you want to carry a bag or two, but its presence weighs the whole thing down. The chain is not covered with a protection, it is better to pay attention to the bottom of his pants.

The front light equipped with the Ebike 28 Pro is just enough to be seen by other users. Its power and directivity are too limited for extra-urban use on unlit roads. The rear light is battery operated and allows you to see properly.

Folding bikes often offer driving sensations cut to their format. The Momabikes E20 Pro suffers on the one hand from its geometry and on the other from its capricious hub motor. The latter, located at the rear wheel, still develops 55 Nm, thus promising easy hill crossing.

The hub motor of the Ebike 20 Pro does not come with a torque sensor. So it starts when the crankset turns, resulting in pedaling that lacks naturalness and a feeling of pretending to pedal quickly. Small wheels and 7 speeds do not provide a significant improvement; you quickly find yourself “pedaling without semolina”, turning to a vacuum to activate the electric assist.

It adds a confusing operation of driving modes, 4 in number (Eco, Tour, Sport and Turbo), controlled by a small box located under the thumb of the left hand. The first two provide very limited assistance that cuts to 17 or 18 km/h. An unwelcome limitation for a bike that remains difficult to ride without assistance. “Sport” and “Turbo” modes are more powerful. A little too much even for the last, reserved for straight lines and climbs. Its use in the city is very dangerous because of its brutal “all or nothing” nature.

However, the couple is welcome to climb the hills. The assist makes you forget about changing gears because it gives all its power to the top. One can easily be tempted to ride this Ebike 20 Pro as if it is a speed bike. Especially since the Shimano Tourney transmission is not the smoothest to use. However, for his benefit and the life of his teeth, it is better to choose the right ratio.

Momabikes chose hydraulic disc brakes on their folding bikes. A good thing on paper, but the unknown origin of these brakes does not inspire confidence. Their performance is quite limited, with braking at 4 meters for a 65 kg rider and perhaps complicated maintenance if there is no data on them.

Good point on the other hand for the screen which is relatively large and remains properly legible, even in the sun. It shows the usual information: easy speed, distance traveled, battery gauge, effective engine power or travel time. It still lacks an estimate of the distance it will travel to actually complete it.

Strong points

  • Easy to fold and unfold.

  • Rolls while folding.

  • The battery is integrated into the frame and is removable.

  • Well equipped.

  • Strong support.

Weak points

  • The machine to break.

How does grading work?

Unsurprisingly, the Momabikes Ebike 20 Pro is not the best folding e-bike on the market. It quickly shows its rolling limits and its engine is capricious. However, for short occasional trips, this folding electric bike will do the trick if space is an important criterion in your choice. You have to take the Momabikes E28 Pro for what it is, that is an entry-level bike that probably won’t withstand daily use.
