One of my recent purchases from Papertrey Ink is the Pedal Pusher stamp set. It's an amazing bicycle set designed by Nichole Heady with matching dies that will even let you create an interactive card with wheels that turn!
Here's my first bike, no doubt many more to come. I embossed the bike frame to give it a bit of a shiny look but it's not that easy to spot in the photo:
