AITA My bike was stolen and people gave me money but the next day won a draw to get a new bike

my 400$ bike was stolen while gardening for a youth group. I share on socials to stay tuned to support by buying some artwork for a new bike. It got shared in the community and some people have donated like 50$ even when I said it’s ok if they want to wait until I make something but they still gave me money. One of my friends did a fundraiser and bought 1 ticket just found out I won enough to buy 2 bikes. I asked to give 1 friend the money she just gave me back. Do I ask the rest of the people the same that idk? (People in community that support youth group)
