  1. Maybe it's the technical API upgrade that the APP team didn't notice. They'll fix it soon. DYU APP is always there on playstore: https://play.google.com/store/search?q=dyu&hl=en_US And you could also download it from here: https://www.fwheel.cc/download-app or https://forum.fwheel.cc/files/
  2. I do have a question regarding the rear-tail light (D3+). I'm not sure where and how to attach it. If you have a link to a manual, that would be great.
  3. You can also buy it here: https://dyu.fwheel.cc/product-category/accessories/
  4. Email at fwheel@fwheel.cc for that

  8. I want buy DYU D3F (with pedals) and I have some questions. Sorry for my English, isn’t so good. 1. There is the possibility bike move alone (without do pedals for some minutes, like scooter) with maximum speed (25 km/h)? 2. This bike has only one speed (the maximum), doesn’t have low speed and medium speed? 3. The App is available for iPhone and has English (and Greek)? 4. Last question, can we have access and find it in market spare parts, in battery, moter, gear shift etc for fix it or change it, in the future damage?

  10. Lightweight DYU Egret weighs 34kg, 20 kg is lighter than the same level products. It has been among the top list of AI research & development, creating a new trend in smart travel. The endurance of the battery has reached 80km, leading the way of magnet motor. The Egret E-bike has loaded the 4th generation DTST smart power assisting system, which has the function posture sensing, riding scenario judging and falling reminding, accident auto aid, riding habit recording, remote control, charging noting, battery malfunction remind, etc. This product also comes with GPS +B
  11. It needs to disassemble the battery box, check whether the connection between the motor cable and the controller is loose, and then unplug and plug the cables again. If the problem still cannot be solved, it is recommended to replace the motor
  12. If it still doesn't work, there should be a problem with the Bluetooth board since you've tested it on several phones. Then you need a new Bluetooth board.
  13. Here is solution from the engineer: 1. Clear the Bluetooth connection record in the phone settings, turn off the Bluetooth, and then turn on the bike, get close to the bike; 2. Enter the APP on phone, click the Bluetooth icon in the upper left corner to turn on the phone Bluetooth; 3. Click on the upper right corner to scan again, the letter DYU will appear after a few seconds, click to enter; 4. When you see the battery temperature data display, it indicates that the connection is successful
  14. Here is a video on adding or replacing the Bluetooth board, may it be of help:
  15. Dear Shaun, I asked the engineer, he said it's not recommened to add the Bluetooth card, which's due to the signal issue. D3F bike frame is metal, which differentiates with D3Plus
  16. Dear Nigel Sharples, DYU D3F has been in stock in Poland again. It arrived 2 days ago. And it takes about 1 week to be delivered to the UK. DYU D3F has a bigger size than DYU D3 Plus. Other parameters are similar with DYU Plus. DYU D3 plus is sold out in Poland at the moment. To order the product, please contact fwheel@fwheel.cc
  17. Of course, here is the certificates of DYU D3F: https://www.fwheel.cc/wp-content/uploads/2019/09/D2FD3F-Test-reports.zip CE, EN15194, LED VDE lamp test are included in the file.
  18. The seat has a problem: I pushed the seat down in the video and now I cannot pull the seat back up. It is stuck -- will not come back up. I took it to a bicycle store and the guy tried to pull it but cannot. I sprayed it with some WD-40 and tried at home, the seat will not come back up. I have attached a video to show the seat stuck.
