There is a man who is regularly on the podium of gravel races I'm interested with, and he rides a road bike on wider tyres. So it is basically not the bike but the rider who wins. However, a "gravel bike" has the characteristics that allow most of us ride long rides in mixed terrain fast, often fully loaded. In this context, Creo 2 ticks all the boxes, and it is not a road e-bike unless heavily modified (such as the one of
@Dazmanturbo). Of course you can make a Creo 1 more gravel capable. All in all, I made my Vado SL gravel capable...
