DYU Electric Bike,16" Folding Electric Bicycle,36V 7.5Ah Battery,Commuter City E-Bike with 250W Motor,Height Adjustable,LED Display,Front Basket,Braking system Disc brake, for Adults Teens

Great little bike for short commutes. I use this bike to commute to work which is about 1.8 miles away. It is mostly up hill on the way there. There are three modes the bike can be used on. On full throttle the bike moves without having to pedal, on pedal assist which makes for smooth effortless riding and when a certain speed is achieved you can just cruise. The button for electric input is handy within reach of the right thumb. When going down hill or on flat areas I just switch the electric input off. I find it is easy enough to pedal in these circumstances which for me is about half of my commute on the way back. I tend to manage three commutes to work before the indicator for the charge is on the last bar and I recharge the bike. It probably would cover one more commute before needing a recharge but I don't care for the range anxiety it will give me 😁. There is a speed limiter on the bike and it will not go any faster even if you pedal like mad with or without the electric input. But I would guess it gets up to a maximum speed of a run- maybe about 6-8miles per hour at a guess. But for me personally this speed is fast enough as I fear I may decorate the street with my teeth if I go any faster. It takes me 15-20 minutes to cover the distance to work one way. The bike has a small foot print. The wheels are small but big enough to not feel every tiny hole in the road. The seat and handle bar height is easily adjusted to what is comfortable for each persons height. I prefer to sit upright and not lean forward when riding. So I have the handle bar higher than the seat height. The small size of the bike ensures it sits in my entry hallway without getting in the way. At work I store it in the changing room. As the battery on this bike is not removable I have to take the bike to an available plug point. For those who may not have a handy plug point for this the same bike with the battery removable option might be a better alternative. In hindsight I would have coughed up the extra 100£ for this option as then it means that charging options are more and as the battery starts to wear down I would have the option to just get a new battery and not a whole new bike. In terms of repairs and maintenance, I had a rude shock in the first month. I do not know even basic bike maintenance and would need to take it to a shop for servicing. In the third week after starting with this bike, my 16 year old decided to test it and rode over the small step outside the front door while seated on the bike and immediately both the tyres went flat. Admittedly the tyres needed filling up and I was waiting for a pump to arrive. I am told that this is likely a pinch puncture where the inner tubes were pinched against the edge of the step with the weight of the rider while the tyres were half full. New tubes are cheap. But, the labour to remove the back wheel mechanism to allow for the tubes to be changed meant I had to pay 50£ in total for both the wheels to be sorted. So now I am committed to making sure the tyres are fully pumped up and watch what I go over when riding. The best thing about this bike is the feature that allows it to be folded neatly into a size that is roughly half of the original bike...size ends up similar to a medium pram. So It can be folded up to fit neatly into the boot of the car. No need for any tools to do do this. Just need some levers released. When I bought it, I had plans to fold it after every use and tuck it with the vacuum cleaner under the stairs. But the bike is heavier than it looks and it becomes a chore to fold after every use and then undo and reset the seat and handlbar height etc. But for the purpose of needing to fold it down occasionally, to fit into the boot of a car, this is a brilliant feature. It comes with a fob like a car key, that can be used to lock the bike. If one tries to move the bike after being locked with the fob, it sets off an annoying alarm and if you try pedaling, it moves like you are pedaling through cement. Even though it is impossible to pedal when off, the bike can be rolled away but with the annoying alarm ongoing.

Ok so I have had this bike for about a month and use it to commute between the Isle of Wight and my brother's place in Portsmouth, twice a week. For the purpose I bought it for, it's excellent and build quality is also good. It folds up very small and I store it in the boot of my car. It's nippy and has some really nice features such as cruise control. It will cruise comfortably at up to 14 MPH which is fast enough for a bike of this size. The areas that I wish were better......battery range for a 16 stone man is not great. Bearing in mind that it doesn't have gears and after about 7 MPH relies 100% on its motor, the battery will take it about 8 miles. With pedaling a bit, I can probably get 10 miles. It's not a deal breaker but I wish it could do a few more between charges. Probably range would be better if you are small and light! Battery is not removable so you have to take your bike indoors to charge it, or do as I have done and buy an inverter for the car so it can charge up whilst folded and stored in the boot. Finally, the four bar power led is pretty poor at providing accurate power readings. I can see that a module is available that will allow accurate readings to your mobile via Bluetooth. I will probably buy this soon. Overall it's a super little space saving commuter bike for less than £500 and should I compare it with savings on taxi's, will pay for itself in 3-4 months.

I bought this bike Jan 2023. It was easy to assemble within 10mins. Charges quickly. I bike 8km a day, x5 days a week and I charge it once or twice a week. It folds easily and is quick- top speed depends on your weight but I reckon 15/20mph. I’m 110kg and it’s been a fantastic little bike. I would recommend checking that the tyres have been put on the correct way so they aren’t wearing the rims off and buying more expensive puncture proof tyres but aside from this would recommend to everyone. It could be improved with a louder horn and gears for when not using the electric. Great buy!

After what I thought was going to turn out to be a positive experience it was not. The bike I recieved , despite being advertised as having pedal assist did not, I then thought maybe it was faulty and DYU replaced the bike for me, but unfortunately the replacement also suffered the same issue for me to believe it did not have pedal assist, only throttle assist, which on a positive note, works well but wanting to conserve battery I didn't want this to be my only option which is why I chose a bike with pedal assist. DYU offered to replace the bike with a different model instead of a refund, which I decided would be ok. Unfortunately after DYU agreeeing to the replacment bike, they decided to not honour it and after many months of excuses and delays, which included, not in stock, not stocking a particular model (even though agreed to replace with it), boxes being damaged and even stating that the ones in stock listed on amazon was a different seller (amazon confirmed this was untrue) also stating they have replacement stock and sale stock and the replacement stock had been sat around for some time so may not work. In the end I recieved a full refund after approximately 3 months. The quality of the bike was really good but the listing was not representative of the functions. I had hoped to continue with the DYU brand but after my customer service experience I will now spend my money elsewhere.

I bought this bike a month ago, it is not as my expectation because of :- 1. It is not assists me while paddle. There is a paddle sensor but its not working. 2. When I put it on CHARGE, it makes loud noise. That is very annoying. 3. Battery is not that powerful, I need to put it on charge every day, But I only use to ride it for 45 minuets. I am very upset about this bike.

Como bicicleta cumple su función. Completamente plegada, debido a la posición en que quedan las ruedas y la falta de puntos evidentes de arrastre, resulta complicado el desplazarse en transporte público. Sin embargo es suficientemente compacta como para no tener que plegarla en la mayoría de siruaciones. El manual de instrucciones del sistema de bloqueo (con mando a distancia) y del ajuste del nivel de asistencia a la pedalada són mejorables.

J'avais commandé deux vélos,un est arrivé poignée cassée dans le transport. Il a été changé rapidement. Ont les a testé plusieurs fois sur long trajet, mi assistance mi électrique franchement parfait. Je suis sur le point d'en commander un nouveau pour mon fils de 14ans qui râle de ne pas pouvoir nous suivre avec le siens. Bon rapport qualité prix. Je recommande.

Recensione pratica pratica. Il prodotto arriva confezionato in una scatola di cartone e la bici piegata su se stessa è tutelata dagli urti. Appena aperta manca solo da installare i due pedali come ovvio che sia. All'interno della scatola trovate anche il caricabatteria con attacco comodo non shucko. Montaggio Praticamente immediato, staccate la plastica, le fascette e le pellicole ed è subito pronta per la prima passeggiata. La batteria arrivata già carica più della metà. Tempo di ricarica la prima volta circa 2,5 ore nel mio caso. La volta seguente circa 5 ore per la ricarica completa. Valutazione d'uso Sono un ciclista di 1 metro e 78 centrimeti con peso di quasi 80 kg. La bici va che è una bomba, tira che una bellezza sia in piano che in strade con dossi. Provata in leggera salita con inclinazione oscillante tra i 10 e 15 gradi è risucita a portarmi su tranquillamente. Comodità del sellino nella media, posso dire che io soffro particolarmente le lunghe tratte ma con questa bici non ho avuto il solito fastidio. Dettagli da evidenziare Come potete notare dalle foto, oltre al design hanno curato molto il raggruppamento dei fili che sono poco visibili e non danno alcun fastidio. Inoltre quando chiusa non tende a riaprirsi da sola al primo movimento. Il punto di equilibrio nella chiusura è giusto e molto utile quando riposta in garage o in auto. Sella e manubrio hanno un buonissimo margine di sali e scendi che consento l'utilizzo trasversale tra bambini, ragazzi e adulti. Praticamente una bici tuttofare. Velocità In piano sono arrivato a toccare i 24km/27km orari assistendola pochissimo con la pedalata. Mantiene tranquillamente i 25km senza perdite di potenza ed è molto utile il sistema di velocità in automatico. Percorrenza Ho provato a utilizzarla con tutta la riserva di energia per vedere quanti km riusciva a percorrere con un pieno. Risultato più che confortante sono arrivato a 32km in piano con pedalata assistita media. Note legali: E' conforme al codice della strada italiano con utilizzo in pedalata assistita e watt 250 del motore.

Mon périple avec le vélo électrique DYU A1F a débuté en juillet dernier. Mon premier exemplaire avait malheureusement un petit souci électrique, se coupant après quelques minutes d'utilisation. Toutefois, le vendeur a fait preuve d'un grand professionnalisme en proposant un remplacement immédiat, avec une communication impeccable et un suivi exceptionnel de la situation. J'ai donc renvoyé le modèle défectueux et reçu en un temps record un tout nouveau vélo parfaitement fonctionnel. Après cette petite péripétie, j'ai enfin pu profiter pleinement de mon vélo. Après près de deux mois d'utilisation, je suis en mesure de partager un avis complet à son sujet. Tout d'abord, il est essentiel de noter que ce vélo est véritablement motorisé, ce qui signifie qu'il peut avancer de lui-même simplement en tournant la poignée du guidon, à l'instar des trottinettes électriques. En ce qui concerne la législation belge, ce modèle est entièrement conforme. Vous pouvez l'utiliser sans permis de conduire tant qu'il ne dépasse pas 25 km/h, ce qui est le cas de ce vélo. Cependant, l'utilisation sur la voie publique est réservée aux personnes de plus de 16 ans, les plus jeunes pouvant s'en servir uniquement dans des domaines privés et en dehors des zones urbaines. Les points forts : Une mise en route extrêmement rapide. Il affronte les pentes de Bruxelles sans sourciller. Une suspension efficace qui atténue les secousses sur les chemins plus cahoteux. Un design robuste et confortable. Le feu arrière s'allume au freinage, tout comme sur une moto, ce qui renforce la sécurité, particulièrement la nuit. Moins de fatigue pour passer d'un point A à un point B. Sa légèreté facilite son transport, y compris dans les escaliers. Pliable, il se glisse aisément dans le train ou se range dans un petit appartement ou studio. Un excellent rapport qualité-prix. Les points faibles : Il faut éviter de pédaler en même temps que l'accélération du moteur au démarrage, sous peine de lever la roue avant, car le démarrage est déjà assez puissant. Le klaxon est très puissant, ce qui peut effrayer les piétons. Il est conseillé d'ajouter une petite sonnette classique pour les prévenir et de réserver le klaxon aux véhicules plus grands. L'absence de dérailleur pour les vitesses au pédalier peut poser problème, surtout lorsque la batterie est déchargée. Pédaler devient alors plus difficile, et les montées deviennent impossibles sans changement de vitesse. Il est impossible de pédaler lorsque le vélo atteint 25 km/h en raison d'un dispositif de limitation de vitesse. La maniabilité de la roue avant est limitée, donc attention aux virages serrés. Les petites roues nécessitent un freinage vigilant pour éviter les glissades. Pas de clé pour démarrer le moteur, seulement un système d'alarme antivol, ce qui signifie que n'importe qui peut l'allumer. Les freins à disque ont tendance à grincer après une courte utilisation, nécessitant un nettoyage régulier avec un produit spécifique. L'autonomie électrique est d'environ 30 à 35 km, donc il est préférable de le réserver aux trajets urbains ou de courte distance de 5 à 15 km maximum. Évitez de transporter de lourdes charges, ce vélo n'est pas conçu pour cela. En résumé, le DYU A1F est un excellent choix pour des trajets courts en ville, offrant une expérience de conduite agréable. Pour ma part, possédant déjà un vélo électrique classique, je l'utilise comme un deuxième moyen de transport pour de petites sorties ou pour me rendre au centre-ville. N'oubliez pas de vous munir d'un solide antivol et d'activer l'alarme à chaque fois que vous laissez votre vélo sans surveillance. Bien que cela ne soit pas obligatoire, je recommande vivement le port d'un casque lorsque vous conduisez ce modèle, ainsi qu'un rétroviseur, car il dépasse les vélos traditionnels et même les trottinettes. Mieux vaut voir ce qui se passe derrière pour une sécurité optimale, tant pour vous que pour les autres usagers de la route. Enfin, sachez que la première charge de la batterie dure environ 4 heures, et qu'il est impératif de la faire avant toute première utilisation. Si le chargeur émet un léger bruit aigu, pas de panique, c'est tout à fait normal, certains chargeurs produisent ce son en raison de la bobine interne. Je vous souhaite de belles aventures sur les routes, en toute sécurité !

DYU model A1F Conclusions basiques: Correcte, sense pretensions. Dades del usuari: pes 98 kg. Alçada 1,73 edat 68 anys. Estat físic correcte. Recepció, abans del estimat, aspecte del embalatge correcte. Un cop desembalat, aprecies que el manual es incorrecte per ser no més que amb anglès i amb una mida de lletra massa petita (recomano baixar el manual del web i visualitzar-ho i traduir-ho en ordinador) amb mancances de informació importants. Tot al seu lloc tret de un parell d'apreciacions. La cadena estava massa tensada i seca (fàcil de solucionar-ho si ets una mica manetes) el sistema de fixació del seient va ser tancat en mala posició i es va fer mal bé parcialment. El vaig poder recuperar. Els pneumàtics els vaig tenir que inflar (normal tenint en compte que no se li va fer cap intervenció a la unitat des de la sortida de origen). La sensació gloval es de "tot controlat" amb certes inquietuds. Bona relació preu prestacions, qualitat. Incorreccions de algunes opinions : La velocitat màxima en cap cas arribarà als 25 km/h pedalejant. En elèctric pur, pot ser si. Es pesada i corra poc (degut al seu desarrollo que es curt, però que permet moure-la). Frena bé i l'impuls inicial és suficient. Les pujades del 25% ni de conya. Un 10% ja la posa en un compromís. La qualitat general compleix mínims. En quan al apartat elèctric, de fet les tres opcions són dos, apagat o encès. Si està encès auras de pedalar i de valent a la que puji una mica, si o si. Sempre tens la opció de donar-li al puny dret i activar l'assistència elèctrica desvinculada del pedalar (il·legal al estat espanyol). La tornaria a comprar, si. El venedor no enganya en la definició del producte tot i certes imprecisions en la pujada màxima superable i la velocitat màxima assolible. No es adecuada per anar per muntanya però és defensa bé en camins de terra que estiguin en bon estat. Els tancaments d'alçada de manillar i seient encara que els apretis molt tenen tendència a permetre que s'enfonsin.
