    Hi everyone. I was reading about the NanRobot D5 over at scooterselect.com. They say it's top speed is 40 MPH maybe 50 MPH depending on how heavy the rider is. Is this the fastest legal electric scooter? Or is there another model I can get that is faster? They say it can do 50 miles on a full charge, I believe this might be true because it has 2 batteries, is this true? Does anyone have the NanRobot D5? Is it ant good? I want to know before I get one. Many thanks 🙂

    Is it durable? I have been riding the D1 for 2 months now and wow. 700 miles of riding it like a BMX bike, jumping curbs, pulling wheelies and riding down stairs. I had 1 rear tire blow out! That is the ONLY problems I've ever had. It's awesome. Thanks DYU and F-WHEEL I'm having so much fun.

    Hallo! I have some problem with Bike D1 when I try to ride. After a few seconds of driving under load, the motor-wheel turns off. After I return the throttle handle to the starting position, I am again ready to start. The display at the time of shutdown does not go out, the voltage remains unchanged ... ... But If during starting I have a time to push the cruies-control button before motor turned off everything is OK in this case (like no problem at all) and I can ride until I stop the bike... ... By the way with a free wheel (without load) , it can rotate for hours without stoppage ... " So It looks like some kind of current protection switch off power. The battery and its voltagу is OK. I opened the motor-wheel and visually everything is OK. I have check the voltage at all three hall sensors (with rotation of wheel) and it is similar per each phase and pick is about 3.27 V. What else can be a problem with ?

    I am electrical engineer by the way (but not electronic engineer) so of course it is not problem with brake

    Hi Alex, thanks a lot for your feedbacks. Before the motor-wheel truns off, did you brake it? sometimes, when you braking, then release it, must fully release, otherwise can not work normally.

    The Bike rides using the accelerator, but it doesn’t work the lights, the horn, nor the bluetooth
  24. 1 point
    Hi, i understand that blowing the horn is normal in many Asia countries, including China, as i have travelled to many of them, but in Europe this is totally different. Blowing the horn in most European countries is even prohibited in certain areas or without reason. It is also considered as extremelly annoying and rude behaviour for people here. So we expect a solution or software update to eliminate this problem. Thank you in advance.

    Was wondering if there are any mods or methods of upgrading F wheel DYU. More speed is main goal
  26. 1 point
    Hi Christopher, Max speed of all our DYU ebikes is 25KM/H. For new ebikes, the factory speed is 20KM/H, you can adjust it to 25KM/H after you ride more than 10KM and it also shows over 10KM in your App.

    With the DYU D3, it is by activating the accelerator for 5 seconds that I activate the cruise mode. I have no problem deactivating it by reactivating the accelerator. When the problem of brakes that do not disable the cruise mode appears, it is only with a long stop that the problem disappears.

    When I have the problem, the bike brakes but when I release the brakes it goes back on its own. On the other hand, I've never had any problem deactivating the cruising mode by re-accelerating. I was not using the application the last time this happened. I'd rather say it was a firmware problem. However, I will try to re-install the application soon to see.

    Ebikes price and quality vary much even though they look the same on apperance,for example, lithium battery price is much higher and quality is much better than ebikes with lead acid battery, even though they both use lithium battery of both lead acid battery, its brand also makes price differ much, such as LG battery price is much higher than normal brand battery,of course it's quality also better. then it's about the material of ebikes, aluminum alloy material better and higher than metal material.

    I found a better way of silencing the horn until the NEW Horn button is depressed. Now it works like one expects... No more random blowing of the horn... RandomHornBlowing.mp4

    Thanks for your valuable information. I noticed the APP department to correct the error in the next update.

    Hi Jesse, Thank you for replying. With the help of some experienced riders, the problem had been resolved. The App does not allow the Bluetooth to be connected to other smart devices (smart watches, health bands etc) while scanning for the DYU. Temporary solution is to switch off or unpair the smart devices, but a more permanent solution is definitely required. Please do look into it. Thank you. PS: Problem occurred on Samsung S8+ with Garmin Fenix 3 and Samsung S7 Edge with Miband 2. Hope this help with your technical team.
