Disclaimer: I was riding at walking pace with my kids and came to a safe complete stop when interacting with the game. It does make getting from Pokestop to Pokestop very many much more easier, rather than having to park the car, and get out and walk to the ones that are slightly OFF ROAD.
Plus, you get to see cooler shit when you’re not in the car:
edit: AND ALL THAT SHIT GOT KINJA’D SO FUCK IT.
So go get an old phone holder, some zip ties, and prepare for getting a sore butt on your inadequately padded bike seat as you hunt for Pokemon!
