Hi there.
Firstly thank you for looking into my bid.
I took a look at the picture you've uploaded.
My advice on it would be to not change the colour of the bike, reason being most of the bike parts are in black and if the you want the main colour of the bike to be different, it wouldn't look natural.
What i can offer you is to enhance the photo by removing objects such as cars and leave and have the photo be more vibrant with it's colours.
Irregardless with what i said, if you really want to change the colour of the bike, it can be done as well.
Hope to hear/work with you soon.
Regards, Raid
