DYU D3S 14 Inch Mini Folding Electric Bike

my son got this bike as a gift. And he is really happy with it. Small and light, but powerful and fast. The whole experience from when we ordered until it arrived was super easy and fast. The bike was securely packed and easy to assemble when it arrived. We are really happy so far 🌟🌟🌟🌟🌟

Surprised that it feels so solid. really nice to ride on.
Many in the family have tested and are positive about this little bike. I am 185 cm and have no problems riding it

I just received it amazing i will order another one i see in the website that i will get free gift a child seat for these period (black Friday,,). I wait for it .

Sturdy well built and definitely the best e-bike under £500

La bike al primo impatto sembrava troppo piccola per la mia persona, pensavo che fosse per bambini. Usandola, poi, mi sono accorta che è molto comoda, maneggevole, leggera e utile nel traffico: permette il trasporto di notevoli carichi e consente di facilitare la pedalata assistita, dà l’impulso con la velocità controllata, senza stancarsi. È davvero comoda da trasportare, per cui ho pensato di portarla con me nel prossimo viaggio In Sicilia.

I tried out my new DYU D3F, it turns on but it doesn't accelerate can anyone help me out?

Hi everyone,
I'm in Essen and I bought a DYU 14 zoll E E-Bike. I've been using it for 6 months but now I can't turn on the power to start it. I have checked the bike's battery and it is working fine. I don't know how to fix it, can you help me?
Thank you very much.

The bike is great.

I am making some youtube vids with it:

I have this bicycle already 5 month and it helps me in any situation, the battery lasts long enough (I rode 25 kilometers and it showed 1-2 sticks all the time) the only negative is that when I folded the bike several times to put it in the car, the wires stretched and the throttle stopped working . I had to fix it

Pregunta la tengo aproximado un mes y me dado cuenta que tiene un juego de olgura en la orquilla,la he comprado por AliExpress y la tienda no me convence la respuesta de el posible fallo

I am very satisfied with this product! This is a compact, foldable electric bike and the quality has surpassed my expectations. This Ebike is easy to install about 10 mins, and easily ride through flat or uphill streets. You can use the pedal assist to workout even if ran out of the battery. So, I plan to purchase a 2nd one for my family and we can enjoy a ride together. The only thing is: carrying it around is a bit heavy for me，It's about 40LB.

Good

My new Dyu 🚲 m

Happy New Year's everyone! Snuck one more ride for 2021 with the thicker foot of snow in Central Park.

Bought for my 11 year old son. He is 5’3, 140lbs. He fits it great. He loves riding it. Even my mom got on it and is thinking of getting herself one. I did have an issue with the seat being torn when we opened the box. However I contacted customer service and they will be mailing out a replacement seat. I was a little worried after reading some of the reviews because they seemed like the customer support was bad. I had a good experience speaking with them.

My daughter loves it so much!

D3F is really worth buying for the price that it is. If your looking for something exciting , small, comfortable, powerful motor, fast , and is easy to assemble in under 5mins. I say it can go about 20 - 25 mph. I weight about 165 and it’s no problem. I still feel the fast speed it puts out like 20 plus mph like nothing. I even hike my 4 yr old son who bout 45-50 lbs , and still goes fast. Very good motor. I use it for just cruising around my neighborhood everyday just to enjoy the outside . I really recommend this bike if you love speed and power . You’ll be Satisfied for what you’ve paid for .

Ok, first, let's start with the ridiculous ease of assembly. I mean really, I'm moderately tech savvy, nothing like my communication OPs Army husband, but am a fair hand and I have to say, I didn't even need to be that. It was almost completely assembled and just folded down. Some very, VERY basic instructions later, and it was unfolded, the pedals placed, charged, and ready to go!! I have been having a hard time on the trails lately keeping up with the husband and kids, so I decided to get this for me and also for my 60 year old mom and dad who REALLY can't keep up on the trails lol.
Let me say, this was very comfortable on my butt and legs, even at 5'7. My dad had no problems or complaints about the seat or pedal reach when he was screwing around on it, either. It took me a hot minute to get used to the speeding up and slowing down, but the brakes are AMAZING. I don't feel like they're mushy at all and when I'm ready to stop... they stop me! Taking turns are easy, the breeze in my hair is a lot of fun, and honestly, the laugh me and my mom get out of my dad having joyrides on it is probably the best thing ever.

The charging cable is long enough to get to the one wonky cord in the garage and still prop it up where I want it. Even dropping it on the ground a couple times hasn't cracked the case or dinged up the metal at all. The tires are thick and sturdy and even running over gravel and grass and twigs haven't touched those beasts. And we have made it through a whole day on the Ghost trails without it going dead. And when it did die at the very very end of our day, pedaling wasn't too much of a chore at that point.

No problems with my bike I’ve ridden over 600miles all good. Love it

very good!!!perfect!

Got my new ride yesterday after using a eScooter for nearly 2 years. Any thing I should be aware of and faults

My DYU D3f has done only 164km in two years since new.
I’m waiting on heart surgery and can’t walk up the hill where I live , so can’t go down into the harbour and maintain my boat.
I’ve managed roughly 60 visits to my boat to carry out work , or just watch a movie and sleep out in that 2 years , so it’s not gone far but it’s been a life saver .
I’d have been housebound without it !
I love this bike , it folds to fit in my dinghy , and is light enough to lift into the yacht when I arrive .
When I get home the balance let’s me carry it upstairs as I live in a first floor apartment, so anyone thinking they can’t manage hills , it’s power to weight and low gears that wins .
I’m 10 stone 2lb , or about 68kg .
I’ve a broken heart valve to only 3 heart chambers pump , the feed artery is 1/3 of the normal diameter , so it really has changed my life this bike .
Switch it on and the blue tooth app is registered named “Marks Heart”
It sure has helped , thank you DYU xxx
You can see the hill is approximately 32 degree from horizontal!

On my yacht , 17kg is light enough for a well balanced grab handle and a swift lift onboard
