wow, amazing man!
from having a background of bikes, all kinds, in my family & knowing them so well, you pretty much done it with each detail.
the one small detail that caught my eye was at the end of the break cable, where it has the little cap on it, it has the dents from where the wrench would dent it.
also the links on the chain has imprints on them, huge detail that really makes a difference.
the only thing i can think of adding, but that’s only my preference, would be having some scratches or some blemishes on the bike. kinda of give the bike some character, even bikes that are fresh out of the box aren’t a perfectly clean slate bikes. but that’s only me.
other then that it looks quite awesome man! nailed ever single part of the bike perfectly.
love to see some wireframes.
