How do you catch the bike in FireRed?

You can't catch a bike in Pokemon FireRed. You receive the bike from Professor Oak after you have defeated Brock, the Gym Leader of Pewter City.

Here's how it works:

1. Beat Brock: Defeat Brock in Pewter City to earn the Boulder Badge.

2. Return to Pallet Town: Go back to Pallet Town and visit Professor Oak's lab.

3. Receive the Bike: Professor Oak will gift you the Bicycle.

You can use the bike to travel faster around the Kanto region. Enjoy your new ride! 🚲
