Marvin also at times rides a red bike. He once used it to go bike riding with Wendy to locate a Blue Jet that was causing tremors all over the country.
Marvin also had a red double-seated bike, which he had Wendy ride with him on the back seat. It was stolen by the Raven, who snatched it up using the powerful Gravity Field of a white dwarfstar, although he was able to recover it.
Marvin rode his blue bike with Wendy riding hers in Cave County, where they discovered what they thought was the tracks of a giantchicken.
