A person who owns a motorcycle and only rides when the sun is out and there’s absolutely no chance of rain.
They ride, for only one reason, to take photos of their bike, and usually themselves, in places close to their home to post on social media.
Instariders only care about the likes they get for their pictures of their bikes and don’t care for the ride itself.
“You think Gavin will come for a ride today?”
“Nah, there’s a little cloud over there and he won’t get any good photos.”
“Bloody instarider.”
