After receiving the Rotom Bike upgrade from Route 9, there are a few locations you can go back to, to find new Pokémon and items. You can do this whenever, but the best time is probably before entering Spikemuth, in case you end up forgetting (like we did).

Use the Flying Taxi to reach Route 2, near the very beginning of the game. You'll arrive just outside Professor Magnolia's home. Go south, through the gate, then head west towards the lake side. Below the bench that's overlooking the lake, there's a space for you to ride the Rotom Bike into the lake.
Once you're in the lake, travel west for a short distance, then follow the river south. After a while, there will be an area of land on the right. Grab the Psychic Seed from here. Keep following the river until you reach the bridge connecting Wedgehurst with Route 2. There will be a sparkling spot hiding a Water Stone.
Return to the lake, then make your way to the centre of the lake. There will be a small island with a powerful Level 50 Drednaw in the middle. Above the Drednaw, search the base of the tree in the very middle for a hidden Rare Candy. Then go around to the north-east corner of the island to retrieve the PP Max.
Re-enter the lake and paddle towards the north-west, where there's another section where you can alight. Near the beginning of this section, there's a stubborn Level 50 Obstagoon standing guard. Follow the path ahead, while going through the tall grass. At the very end, past the Trainer Tips sign, you'll find TM69 Psycho Cut.
This is the only place where wild Feebas are found. With an abyssmal 1% chance. Better than in Ruby and Sapphire though... But if you can wait until beating the game, you can catch Milotic in the Lake of Outrage or South Lake Miloch when there's fog.
Next, set a course for the idyllic town of Turffield! Head for the far-eastern part of town, near the exit to Route 5. Right before the bridge to Route 5, there's a space just above, where you can enter the river. Follow the river up, while being mindful of a Level 50 Crawdaunt. At the end, you'll find TM11 Solar Beam on the left.
Other Places to Visit
Within the Wild Area, you can now explore more of West Lake Axewell, East Lake Axewell, North Lake Miloch and South Lake Miloch. In addition, you can reach Axew's Eye and the Lake of Outrage, but be wary of powerful Pokémon there!
