The 52 V \/ 27 Ah battery and 250 W (1000 W maximum power) motor allow you to expect not only a considerable range, but also a very fun character. But what kind of bike is this in reality? Is it comfortable? Can it still be called a bike that you want to ride? And what is it like in everyday use? About this and more in this review.<\/p>\n

<\/span><\/p>\nUnpacking<\/h2>\n
Duotts F20 atkeliauja saugiai supakuotas ir su visais reikalingais priedais – tai jau \u012fprasta \u0161iam gamintojui. Pats i\u0161pakavimas dideli\u0173 staigmen\u0173 nesukelia, viskas sud\u0117ta tvarkingai, tod\u0117l surinkimo prad\u017eia gana paprasta.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-2.jpg\" "\\"Duots")
<\/span><\/p>\nTrue, the instructions turned out to be somewhat unusual. It lacks clear steps, such as how to install the trunk or seat, and it also does not indicate which screws to use everywhere. The assembly itself is not complicated, but in places you have to turn your head. The whole process is in this video:<\/p>\n
First impressions<\/h2>\n
I\u0161 pirmo \u017evilgsnio Duotts F20 atrodo gerokai brangiau nei kainuoja. Retro motociklo stilistika \u010dia i\u0161laikyta prakti\u0161kai visur – nuo priekinio \u017eibinto iki r\u0117mo linij\u0173. Vis d\u0117lto yra prie ko prikibti. Ant r\u0117mo esantis u\u017era\u0161as www.duotts.com atrodo keistai ir labiau primena reklam\u0105 nei dizaino element\u0105. Taip pat kiek nuvyl\u0117 laid\u0173 i\u0161ved\u017eiojimas. D\u0117ka motociklo dizaino, \u010dia tikrai b\u016bt\u0173 galima sumontuoti priekin\u012f dangtel\u012f, po kuriuo tuos laidus b\u016bt\u0173 galima pasl\u0117pti.<\/p>\n

<\/span><\/p>\nThe build quality is typical of this manufacturer and is good. There are no creaks or extraneous sounds while driving, except for the work of the front shock absorbers when driving over deeper potholes. True, during the first ride I lost one leg part, which, apparently, was not properly attached at the factory, so before the first ride I would recommend additionally checking the tightness of all the screws.<\/p>\n

<\/span><\/p>\nComfort and driving feel<\/h2>\n
Tik atsis\u0117dus prisiminimais gr\u012f\u017eau \u012f vaikyst\u0119 ir va\u017ein\u0117jimus \u201eDelta\u201c motoroleriu. F20 tai ne tik retro dizainas – jis i\u0161 ties\u0173 sukuria jausm\u0105, kad s\u0117di ant elektrinio motorolerio, o ne ant dvira\u010dio. Lenkta s\u0117dyn\u0117 pasirod\u0117 itin patogi. Ji n\u0117ra pernelyg plati, kad trukdyt\u0173 minti, o \u012fsib\u0117g\u0117jant nesusidaro jausmas, jog slysti atgal. Net ir ilgesni\u0173 kelioni\u0173 metu nuovargis juntamas minimaliai.<\/p>\n

<\/span><\/p>\nVairo auk\u0161tis parinktas gerai, o mygtuk\u0173 i\u0161d\u0117stymas patogus ir lengvai pasiekiamas. Visgi vietos papildomiems aksesuarams \u010dia prakti\u0161kai n\u0117ra. Jei planuojate tvirtinti telefono laikikl\u012f, apie sprendim\u0105 vert\u0117t\u0173 pagalvoti dar prie\u0161 \u012fsigyjant dvirat\u012f. Taip pat manau, kad gumin\u0117s ranken\u0117l\u0117s (nors ir patogios) nelabai dera prie bendro dizaino – nor\u0117\u010diau, kad Duotts b\u016bt\u0173 pasirink\u0119 kiek \u012fdomesn\u012f sprendim\u0105 ir geriau i\u0161laik\u0119 bendr\u0105 retro stilistik\u0105.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-21.jpg\" "\\"Duots")
<\/span><\/p>\nThe F20 has full suspension, so it handles minor bumps quite well. However, the front shock absorbers are not adjustable, and when driving over deeper potholes they bounce back quite quickly and make an unpleasant crashing sound. This is not a critical flaw, but when driving on poor quality roads you will definitely notice this sound.<\/p>\n

<\/span><\/p>\nEngine and driving dynamics<\/h2>\n
\u0160iam dvira\u010diui traukos netr\u016bksta – startas pakankamai energingas, o \u012fkaln\u0117s didesni\u0173 problem\u0173 nesukelia. Visgi gana greitai susidar\u0117 \u012fsp\u016bdis, kad maksimalus greitis dirbtinai apribotas. Dviratis tolygiai greit\u0117ja iki ma\u017edaug 45 km\/val. (ekran\u0117lyje rodomas 39 km\/val neatitinka GPS rodmen\u0173, kurie mano nuomone yra tikslesni), o v\u0117liau tarsi atsiremia \u012f nematom\u0105 sien\u0105. Atsi\u017evelgiant \u012f turim\u0105 gali\u0105, atrodo, kad potencialo pasiekti 50 km\/val. \u010dia tikrai yra.<\/p>\n

<\/span><\/p>\nAkseleratoriaus veikimas kiek nuli\u016bdino. Vos \u0161iek tiek pasukus gazo ranken\u0117l\u0119, variklis i\u0161 karto pateikia prakti\u0161kai vis\u0105 gali\u0105. \u017dinoma, tai ne pats staigiausias elektrinis dviratis, bet vis d\u0117l to va\u017eiuojant l\u0117tai ar manevruojant ank\u0161tose vietose sunkiau i\u0161laikyti skland\u0173 jud\u0117jim\u0105. Va\u017eiavimo poj\u016btis primena \u201esquare wave\u201c kontrolerius – akceleratorius labiau veikia kaip variklio \u012fjungimo ir i\u0161jungimo jungiklis, o ne leid\u017eia tiksliai dozuoti gali\u0105. <\/p>\n

<\/span><\/p>\nMinimui su variklio pagalba pasirinktas grei\u010dio jutiklis.

Nors sukimo momento jutiklis suteikia nat\u016bralesn\u012f va\u017eiavimo poj\u016bt\u012f, \u0161io modelio atveju toks sprendimas atrodo visi\u0161kai logi\u0161kas. \u012evertinus bendr\u0105 F20 charakter\u012f, sunku \u012fsivaizduoti, kad dauguma pirk\u0117j\u0173 reguliariai mins pedalus.<\/p>\n

<\/span><\/p>\nFrankly, the F20 is not an electric bike that you want to think about. During the entire testing period, I used the pedals only a few times seriously. The low seat, geometry and the whole character of this model clearly suggest that it is designed to be ridden using the accelerator. The pedals are needed here more to fit the concept of an electric bike, rather than for everyday use. <\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-38.jpg\" "\\"Duots")
<\/span><\/p>\nScreen and app<\/h2>\n
The screen left a very good impression. Its size and position are perfectly chosen, and the information is easy to read even in bright sunlight. After the C29 series models, this is a pleasant change, because I had no complaints about visibility with glasses here. However, the content of the screen itself could be used better. Although there is certainly enough space on it, the turn indication is not displayed, and the battery level is presented only in divisions. <\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-23.jpg\" "\\"Duots")
<\/span><\/p>\nThe app left a twofold impression. It allows you to update the software, view your ride history, use navigation, see your bike's location (when it's on), and turn on a sound signal that sounds when you move your bike. There's no shortage of features, but the app itself doesn't seem particularly complete. Navigation is free for one year, but I couldn't find an option to extend it after that period.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-45.jpg\" "\\"Duots")
<\/span><\/p>\nBrakes<\/h2>\n
The F20 is equipped with ZOOM hydraulic disc brakes and they do their job very well. The stopping power is more than enough even at maximum speed, and the levers can be conveniently operated with one finger. The F20 brakes really match the character of this bike. Considering the dimensions and character of this model, such brakes are simply necessary here. <\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-8.jpg\" "\\"Duots")
<\/span><\/p>\nDriving uphill<\/h2>\n
After switching from the Duotts C29 Max, there is clearly a higher torque here. Although the maximum speed is not so high, acceleration is a little faster and driving uphill is much easier on the F20. In Vilnius, the Narbuto g. hill is overcome at a speed of 38 km\/h, and at the steepest point of \u017delvos g. the speed drops to 11 km\/h.<\/p>\n

<\/span><\/p>\nWhat did we like?<\/h2>\n
The biggest impression I had was that the F20 is completely different from a regular electric bike. As soon as you sit down, you feel like you are riding a small electric scooter. The comfortable seat, relaxed riding position and a sufficiently powerful engine allow you to simply enjoy the journey, and not think about pedaling. This is one of those models that you just want to sit on and ride. <\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-27.jpg\" "\\"Duots")
<\/span><\/p>\nI also liked the hydraulic brakes. They work reliably, are easy to press with one finger and give more confidence when riding at higher speeds. I would also add to the pluses the screen, which is perfectly visible even on a sunny day, and the unique design that always attracts the attention of others.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-34.jpg\" "\\"Duots")
<\/span><\/p>\nWhat we didn't like?<\/h2>\n
Perhaps the biggest disappointment is the accelerator. Personally, I would like a much smoother power distribution. The situation would be somewhat improved by a speed limit based on the assistant levels, but here the accelerator always reaches maximum speed, regardless of the selected level. <\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-32.jpg\" "\\"Duots")
<\/span><\/p>\nI also really wish Duotts would finally manage to hide the cables on the front more neatly. The screen is technically very good, but the software part of it does not seem to use its full potential, and the Duotts app seems unfinished. These are not critical shortcomings, but they are precisely what prevent the F20 from becoming almost perfect in its class.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-43.jpg\" "\\"Duots")
<\/span><\/p>\nVerdict<\/h2>\n
The Duotts F20 is not an electric bike in the traditional sense of the word. It is more of an electric scooter with pedals. If you are looking for a bike for active riding pleasure, you will definitely find better options on the market. However, if you want a comfortable vehicle for daily trips that stands out from the crowd, has a powerful engine, a comfortable seat and allows you to simply relax and enjoy the ride, the F20 leaves a very good impression.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Duotts-F20-17.jpg\" "\\"Duots")
<\/span><\/p>\nFor me, it is not without its flaws. The throttle control itself could be smoother, and a few small details show that the manufacturer still has room for improvement. However, the F20 has become one of the most interesting electric bikes I have tested. Not because it is the best in all areas, but because it has a clear and distinct character. Every time I rode it, I found myself looking for a longer route to my destination. And this is probably the best compliment I can give the Duotts F20. <\/p>\n
