Comfort and ergonomics
Unlike its cousin 28 Pro, the price positioning of the Ebike 20 Pro does not really leave any doubts at first glance. Its aluminum frame reveals clearly visible welds and a somewhat messy finish overall. Too bad, because Momabikes makes the effort to integrate the battery into the frame to make it more discreet. The execution unfortunately sins somewhat by a slight lag in the assembly.
For a folding bike, the E20 Pro is relatively heavy. It still displays 23 kg on the scale, much more than the 18 kg of a Onemile Nomad. This overweight is partly to be put on the back of the battery and its very large capacity, as well as on the integrated equipment of office, including a rear luggage rack rather rare in this segment. It will still be necessary to take into account the weight of the electric bike when slipping it into a car trunk or taking it down the stairs of the metro.
Fortunately, the Momabikes Ebike 20 Pro folds up quite easily and then only occupies a volume of 80 x 77 x 41 cm. Without being the king of contortion, it remains correct. Once folded, the assembly remains well maintained by a magnetic system and the E20 Pro can be moved on its wheels by holding it by the saddle.
Unfolded, the Ebike 20 Pro has a somewhat special geometry. Its open frame, easy to step over, is suitable for cyclists from 1.55 to 1.90 m. However, people under 1.75 m may find it difficult to find a comfortable posture as the distance between the saddle and the handlebars is great. This requires a forward posture which is not in line with the steering and the rest of the geometry.
The handlebar offers satisfying comfort with decent ergonomic grips. Its height can be adjusted, a very good thing for tall cyclists. The various levers and shifters can be positioned according to individual tastes 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 does offer one. The latter offers an unfortunately very limited movement and slams quickly at marked passages, such as sidewalks or speed bumps. Perhaps it would have been wiser to opt for wider tires than the 20-inch Panaracers in 1.75 inches wide.
The plastic fenders are of good quality. The one placed at the front is missing a few centimeters to fully protect the shoes from splashing water. The rear rack is welcome if you want to carry one or two bags, but its presence weighs down the whole thing. The chain is not masked by a protection, it will be better to pay attention to his bottom of pants.
The front light that equips the Ebike 28 Pro is just good 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 powered and allows you to be seen properly.
Folding bikes often offer driving sensations that are truncated by 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, housed in the rear wheel, still develops 55 Nm, thus promising easy hill crossings.
The hub motor of the Ebike 20 Pro does not come with a torque sensor. It therefore starts up as soon as the crankset turns, which results in pedaling that is sorely lacking in naturalness and a feeling of pretending to pedal quickly. The small wheels and the 7 speeds do not offer a very important development; you quickly find yourself “pedaling without semolina”, turning in a vacuum to activate the electric assistance.
Added to this is a confusing operation of the driving modes, 4 in number (Eco, Tour, Sport and Turbo), which are controlled via a small box located under the thumb of the left hand. The first two deliver very limited assistance which cuts off at 17 or 18 km/h. An unwelcome limit for a bike that remains difficult to ride without assistance. The “Sport” and “Turbo” modes are much more punchy. A little too much even for the last one, which will be reserved for straight lines and climbs. Its use in the city is too dangerous due to too brutal “all or nothing” behavior.
The couple is however welcome to climb the hills. The assistance can make you forget about changing gears as it gives all its power uphill. One could then easily be tempted to ride this Ebike 20 Pro as if it were a single-speed bike. Especially since the Shimano Tourney transmission is not the smoothest to use. However, for his good and the life of his teeth, it is better to choose the right ratio.
Momabikes opted for hydraulic disc brakes on their folding bike. A good thing on paper, but the unknown origin of these brakes does not encourage confidence. Their performance is quite limited, with braking in 4 meters for a 65 kg rider and probably complicated maintenance in the absence of data concerning them.
Good point on the other hand for the screen which is quite large and remains correctly readable, even with the sun. This displays the usual information: instantaneous speed, distance travelled, battery gauge, effective engine power or travel time. It still lacks an estimate of the distance that can still be traveled to be truly complete.

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. Nevertheless, for short occasional trips, this folding electric bike can 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 to say an entry-level bike that probably won’t withstand daily use.
