The bike info here.
As you can see, this e-bike comes with Intuvia display.
Can I remove Intuvia display and connect to the brackets immediately a Nyon BUI275? or it needs a completely new installation with wires etc?
The remote control for the handlebar, is it easy to install?
There is lots of info in this old thread about the intuvia to nyon retrofit: https://electricbikereview.com/forums/threads/nyon-retrofit.16260/. You can ignore the references about the hacks we used to have to do to get around the Bosch download restrictions for North America. Bosch has long since removed those obstacles.
