Mauville City

Mauville is a utility hub. Get a Bike from Rydel’s Cycles. The Mach Bike is faster and required for some slopes; the Acro Bike handles tricks and rails. You can swap later, so pick Mach Bike first if you want broad utility.

Get HM06 Rock Smash from the man in the southeastern house. You cannot use Rock Smash outside battle until Wattson is defeated, but you need it soon for Rusturf Tunnel and the northern route.

Wally challenges you outside the Gym with a Ralts. It is more of a character beat than a boss fight, but it sets up his long-term arc. After Wally leaves, Wattson’s Gym is open.
