Question: Do Vado's Include the Turbo Connect Display (TCD)

Yep, TCD is hardwired into the bike. There's an extra part you can install to prevent folks from removing the display. Recommended to install, but not required. It looks like a metal butterfly stitch kind of thing.
Is that piece available to purchase after market?
No, it comes with all Como/Vado bikes that come with TCD. I've got some upgrade kits in the shop so I can check if they came with it too. I know I have a few extra of those bits too.
please let me know if I can purchase one.
my Vado 5 is 2020 and it didn’t come equipped with one.
