What do i do if my mom?

what do i do if my mom keeps saying i can't bike ride?. i'm 24 i have a hearing loss in my left ear i hear normally in my right. an audiologist from many years ago said biking is very dangerous for me. i dont balance very well it's also dangerous because i can't hear from my left side what's going on. there are deaf bikers right? maybe i should tell my mom that. maybe i should convince her i could try it if it doesn't work out then it doesn't work out. i went to a rollarblading party back in the 5th grade people held on to me. i do have a set of rollarblades. i was born with my hearing loss didn't know till i was 5. as i said it was many years ago. i mentioned it to my mom again my mom said you survived not bike riding. if she keeps saying no then i'll do it when i move out.
