Step 1: Bicycle time
When you enter the city some Team Plasma Grunts are attacking the daycare man! Seek revenge. When you beat the Grunts the man will give you the bicycle in thanks. Go into your bag in the key items section and register it.

Step 2: Meet Bianca
After you get the bike you meet Bianca. She tells you there are many facilitys in Nimbasa City.

Step 3: Get the Vs. Recorder
Go to the Battle Subway in the main area (aka if you've gone across a bridge, you've gone too far!) in the center. Before you enter, a woman stops you and gives you a Vs. recorder.

Step 4: Challenge the Subway
Inside the Battle Subway you can challenge trainers. After you beat seven trainers (and don't let me convince you there are only seven), you will get Battle Points (BP). Best of all, BP can be used to buy items!

Step 5: Take a train to Anville Town
In the Gear Station of the building, you can take a train to Anville Town. Let's go to Anville Town... later.

Step 6: Get Strengh
A guy in a house in the main area will give you HM04 Strengh when you talk to him.
