Comfort and ergonomics
Unlike its cousin 28 Pro, the price positioning of the Ebike 20 Pro really leaves no doubt at first glance. Its aluminum frame reveals clearly visible welds and a somewhat messy finish overall. A shame, because Momabikes makes the effort to integrate the battery into the frame to make it more discreet. Unfortunately, the execution sins a bit due to a slight lag in the assembly.
For a folding bike, the E20 Pro is relatively heavy. It still shows 23kg on the scale, much more than the 18kg for a Onemile Nomad. This extra weight is due in part to the rear of the battery and its large capacity, as well as the integrated office equipment, including a rear luggage rack that is quite rare in this segment. It will still be necessary to take into account the weight of the electric bicycle when putting it in the trunk of a car or taking it down the subway stairs.
Fortunately, the Momabikes Ebike 20 Pro folds quite easily and only occupies a volume of 80 x 77 x 41 cm. Without being the king of contortion, he is still correct. Once folded, the assembly is well maintained by a magnetic system and the E20 Pro can be moved on its wheels by holding it by the seat.
Unfolded, the Ebike 20 Pro has a somewhat special geometry. Its open frame, easy to step on, is suitable for cyclists from 1.55 to 1.90m. However, people shorter than 1.75m may have difficulty finding a comfortable position as the distance between the saddle and the handlebars is large. This requires a forward stance that is not in line with the steering and the rest of the geometry.
The handlebar offers satisfying comfort with decent ergonomic grips. Its height is adjustable, something very good for tall cyclists. The different levers and gear levers can be placed according to the tastes and morphology of each one, but the control of the Shimano Tourney derailleur is not the most practical.
While most folding electric bikes don’t have a suspension fork, the Ebike 20 Pro does. The latter offers unfortunately very limited movement and hits quickly on marked passages such as sidewalks or speed bumps. Perhaps it would have been wiser to opt for wider tires than the 20-inch Panaracer at 1.75 inches wide.
The plastic fenders are of good quality. The one placed in the front is a few centimeters short to completely protect the shoes from splashes of water. The rear rack is welcome if you want to carry a bag or two, but its presence weighs everything down. The chain is not masked by protection, it will be better to pay attention to the bottom of your pants.
The front light that the Ebike 28 Pro is equipped with is 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 operated and allows you to be seen properly.
Folding bicycles usually 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, which promises easy hill crossing.
The hub motor of the Ebike 20 Pro does not come with a torque sensor. So it kicks into gear as soon as the cranks turn, resulting in very unnatural pedaling and a faux-pedaling-fast feel. The small wheels and the 7 speeds do not offer a very important development; you quickly find yourself “pedaling without grits”, spinning in a vacuum to activate the electric assistance.
To this is added a confusing operation of the driving modes, in number of 4 (Eco, Tour, Sport and Turbo), which are controlled through a small box located under the thumb of the left hand. The first two offer very limited assistance that cuts off at 17 or 18 km/h. An unwanted limit for a bike that remains difficult to ride without assistance. The “Sport” and “Turbo” modes are much more powerful. Too much even for the last one, which will be reserved for straights and climbs. Its use in the city is too dangerous due to too brutal “all or nothing” behavior.
However, the couple is welcome to climb the hills. The assist can make you forget to change gear as it gives all its power uphill. Then one could easily be tempted to ride this Ebike 20 Pro as if it were a single speed bike. Especially since the Shimano Tourney drivetrain isn’t the smoothest to use. However, for your sake and the life of your teeth, it is better to choose the right ratio.
Momabikes opted for hydraulic disc brakes on their folding bike. Somewhat good on paper, but the unknown origin of these brakes does not inspire confidence. Its performance is quite limited, with braking in 4 meters for a 65 kg cyclist and probably complicated maintenance due to lack of data on the matter.
Good point on the other hand for the screen that is quite large and remains correctly readable, even in the sun. It shows the usual information: instantaneous speed, distance traveled, battery indicator, effective motor power or travel time. It still lacks an estimate of the distance that can still be traveled to be really complete.
Easy to fold and unfold.
Rolls up while folded.
Battery integrated in the frame and removable.
Engine to tame.
Heavy and bulky for a folding bike.
Entry level transmission.
One frame size.
How does the rating work?
Unsurprisingly, the Momabikes Ebike 20 Pro is not the best folding electric bike on the market. It quickly shows its rolling limits and its engine is capricious. However, for short occasional trips, this folding electric bike may do the trick if space is an important criteria in your choice. The Momabikes E28 Pro must be taken for what it is, that is, an entry-level bike that probably won’t stand up to daily use.
