Bird ES4-800 Dual Battery 8-Mile Range 800-Watt Motor Electric Scooter (Renewed) EXPIRED

Here are some answers to some FAQs.

• Yes, some individuals cannot connect to the Segway app (BT issues), others are lucky and are able to do this. This seems to be dependent on the dashboard that was placed on when refurbishing these. If you have a blinking bluetooth icon on your dash, that means you were lucky, pair it through the app, NOT your phone's bluetooth setting

• If you temporarily see a BT icon flashing and it goes away, you need a new dashboard or send out your current one to be flashed

• Yes, FW gets stuck at 47% when trying to update

• Want to switch between MPH and km/h? Download the Nine Dash app (Android only)

• Want to change the lights on the deck/board? Download M365 Tools (Android only)

• Yes, there are individuals who can't see the charging % update in real time while it is charging, likely due to not having BT enabled dashboard

• For those who want to fix the BT issues, you may have to flash your current dashboard (if the circuit board in yours is purple, there is currently not a ton of information on those, so you may have to order another one to flash) in order to enable BT or buy an OEM dashboard if you don't have the skills/knowledge to do the prior way. You can also purchase a flashed aftermarket one. Click the link below for a tutorial if you want to flash it yourself

Here's a reputable site that offers dashboard flashing. I've had a few conversations with one of the owners and just confirmed that if you have a purple circuit board when you take your dash off, you cannot flash this and will have to purchase another dash that can be flashed or a pre-flashed one (which they also sell).

• Is there a way to fold it? No, but it is very simple and quick to disassemble it if you need to transport it, only 4 security torx bolts holds the stem to the deck/board

I also contacted the company that renews/refurbishes these about the issues and this is their reply

• The ES4-800 Bird manufacturer has not developed a customer based mobile phone app for this model.

• The Segway ES1 app IS NOT compatible with the ES4-800 Bird scooter but you may get some limited functionality from the app.

• The Bluetooth function is used only by the factory to upload unit operational firmware to the ES4-800 Bird scooter.

• The unit has been hardcoded to run in "S"ports mode / full speed range. You cannot switch to the other limited speeds 1 & 2.

• There are two version of dashboards used by the manufacturer, some of the ES1-300 units have dashboards that display the Bluetooth logo and some do not.

SOLUTION TO REGAIN RETAIL FUNCTIONALITY BACK (most)

• Purchase an aftermarket dashboard on Amazon (any of them should be fine, they're just rebranded) (easiest way, you can also flash your dash if you have a green board with stlink, if you don't know what this means, just purchase another dash)

• Follow this video to remove your dash board https://www.youtube.com/watch?v=b...EJY&t=937s, you need to purchase a set of security Torx bits. Harbor Freight has a pretty inexpensive set for ~$10 that includes many.

• After re-installing, download the Segway application. Make sure you have bluetooth and location on and pair the scooter through the app, not through your phone's setting. Update FW. So far, BMS updates fail with aftermarket, not confirmed yet if it succeeds with an OEM dashboard (it is now confirmed that BMS updates will successfully update with an OEM dashboard)

• Next, follow the instructions below to regain retail functions like speed mode and derestricting your scooter's speed back to retail (~18 mph).
  
  1. On a Windows PC with bluetooth install Ninebot-Flasher by majsi from the Microsoft Apps Store
  2. Connect to the Ninebot ES2/ES4 and in the white box, type your serial number in with one change, change the fourth character to a T. So, for example, N2GRDXXXXX to N2GTDXXXXX
  3. With the cursor in the field press Ctrl-Alt-A
  4. Press the Write ESC Sn button
  
  There are other programs you can use to change the SN, here's another one (I personally haven't used it, so can't give instructions)

• Ninebot IAP, an alternative to Ninebot-Flasher (PC/Windows only). For people who are unable to use Ninebot-Flasher in their current Windows 10 OS (it failed to connect to my scooter), Ninebot IAP worked for me.
  
  1. Go to https://iap.scooterhacking.org/get
  2. Click "DOWNLOAD SETUP X86" and install it on your PC
  3. Launch program, click "Start scan" to find your scooter's name and bluetooth id, then click "Connect"
  4. After successful connection, click on "Tools" tab, then "Change SN" button, a mini popup window will appear
  5. Type in your serial number in with one change, change the fourth character to a T. So, for example, N2GRDXXXXX to N2GTDXXXXX
  6. Click "OK". Quick note: you might have to do this once or twice. Windows threw some random error on my first try.
  7. Disconnect scooter and connect it back to your Segway app and check your scooter's serial number, it should be changed.
  
  The Segway app will treat this as a new scooter and will send you through the intro again (warnings about safety, etc.). You'll noticed that in the Select Device dropdown menu, you'll see two scooters with the same bluetooth id but different scooter thumbnails - and they both can connect to the same scooter! One is full featured (with ES2 designation, at least for me) and the other, limited featured (before serial was changed). I'd recommend unlinking both, and just link to the scooter again to always connect to the scooter with all features available.

OEM DASH UPDATE

For those waiting for an update with an OEM dashboard, here it is.

Those who purchased an aftermarket dash could not update the BMS. but had access to all other retail functions, with an OEM dash, I was able to update the BMS (I believe the latest is 1.4.9?). Also, someone gave me a great tip, but wanted to confirm it on my end, if you can borrow an OEM dash from someone, you can update everything and then change back to your previous dash (if you were lucky to get a BT enabled one, I believe purple boards = BT enabled), all retail functions will still remain on the scooter.

Recently found out by another individual that BMS also updates with an aftermarket dash that's been flashed with OEM FW, there are sellers on ebay who sell these, ~$30. The issue with these according to some individuals is that the BT update doesn't seem to hold after exiting the app, it looks like it succeeded, but reverts back when the app is closed and reopened.

Another finding - User reported that after updating the FW with an aftermarket dash (non-flashed), they were able to re-install their purple dash and it allowed them to update the BMS to 1.4.9.

Replacement Parts and Free Helmet

For those with missing or broken parts. I can confirm you can contact the warranty company for replacements, all you need is your receipt and send them a couple of photos for reference. I was able to get a new fender and some bolts replaced.

Email - Support@CMSwarranty
Phone - 734-365-7914

Bonus - Confirmed this still works
Don't forget, Bird will also send you a free Helmet if you used their app this last year, All you need to pay is shipping. https://www.bird.co/blog/bird-off...et-selfie/


WARNING

Do not use the electronic brake (the brake on the handlebar) to slow down while going downhill, you can potentially fry something and thus resulting in a brake failure. Use the rear brake located on the rear wheel by stepping on it or a combination of the two (slow down slightly with the rear brake and then use the e-brake), do not rely solely on the e-brake to slow down when going fast (20 mph+). The e-brake failure is likely due to the regenerative braking function this scooter has, it sends too much energy back to the circuit board and poof.
