You won't need to press anything else to use the Water Mode Rotom Bike. Ride it towards the water & it'll automatically transform! It also does the same when you go back to land.
Get to Previously Inaccessible Places
With the Rotom Water Bike, you'll be able to go to places cut off by water that you weren't able to get to before. Often these places include items, TMs, and even rare Pokemon for you to catch!
