I just bought an e-bike from Wiggle's demo fleet and am having problems with the electronics. I think I need to do a firmware update but I can't get into the E-tube app which allows me to configure the settings.

I tried using a passkey of "000000" to access the setting, but it didn't work and I don't know any other default passkey to try.

Is there a way to reset the passkey without knowing the current one?

Is there a recommended way to contact a Shimano for product support?

    Hey John. Your question is really hard to follow. Could you add some punctuation, line break, and a little more detail?

    With problems like this, the seller should be the first to contact.

    You bought something from a shop. It doesn't work. You need to take it up with them. It doesn't matter that it's ex-demo, unless this specific issue was brought to your attention before you bought it.

    @ojs I get that shops must help with faulty goods, but the question is still valid for anyone who forgets their passkey or buys a second hand bike for example, where consumer protections don't apply

You can reset the Wireless passkey for 11-speed Di2 - even if you don't know the current one - by connecting your bike to a windows computer/laptop using the charger. If you're on 12-speed Di2, you need a bike shop to change it for you.

Download e-tube for windows at https://e-tubeproject.shimano.com

Important: if you're using the charger, SM-BCR2, then the latest E-Tube Project version (V5 / Professional) will not work. You need version 3.4.5 or v4.0.4 from the archive page: https://bike.shimano.com/en-EU/e-tube/project/archive.html

Personally I prefer version 4.0.4, especially since v3.4.5 no longer connects to the internet for firmware updates. However, in some occassions version 4.0.4 will complain that the SM-BCR2 firmware is 'old'. The fix for that is to download 3.4.5, and use that to connect to the bike once. Doing so will update the BCR2 firmware in the background.

Version 3.4.5 will complain that it cannot connect to the internet, but you can ignore that message and just click 'ok' and 'connection check'.

In v3.4.5 you change the passkey like this:

  • Connect the bike to your computer using the charger and Junction A
  • Open the e-Tube windows app
  • Make a connection by clicking "connection check"
  • Click "Bluetooth LE settings"
  • Set a new passkey

If you're using v4.0.4, open the customize screen and then the EW-WU111 details page.

You can now use the passkey you just set to connect to your bike using BluetoothLE/ANT+. The Passkey is required for wireless connections only.

Also: if you really want to update firmware then I recommend using a computer (over USB) rather than the mobile app. It a bit safer. You can update using the mobile app, of course.. but as far as I'm concerned the mobile app's main feature is changing settings easily (out on the road).

  • That's all well and good Terry but what if you don't have a PC?

    Is the point here that you can reset the passkey, without knowing the existing one, while it is plugged in to a pc over a wired connection, and that the passkey is for wireless communication?

    cool beans, it was implied that if someone followed the instructions, they would have success, but I love me some clarity
