In the original Pokemon games, the bike costs a ridiculous amount of money. So after first encountering it you keep playing the game until you come across a man who has a bike voucher. My question is, can you instead earn enough money to purchase the bike, and get it that way as opposed to using the voucher?
It is impossible, the bike costs 1,000,000, but you can only hold 999,999.
