Harley-Davidson and Marvel have teamed up for a collection of 25 superhero and supervillain-inspired motorcycles, coinciding with Captain America's 75th anniversary. Harley-Davidson dealerships across Australia and New Zealand participated in creating custom bikes to celebrate characters like Thanos, Thor, Iron Man, Black Panther, Spider-Gwen and more.

The custom motorcycles match some of Marvel's most popular characters with Harley-Davidson's most popular models. For instance, the Black Widow Iron 883 is "all blacked-out, stripped down custom aggression...[and] stands alone, an iconoclast, like the solitary Black Widow herself," while the Hulk's Fat Boy Lo is "big, mean and eye-popping... squat, super strong and ready to unleash [its] superpowers." There's even a Spider-Gwen-themed bike, highlighting a relatively new addition to the Marvel canon.

You can view full descriptions for all the bikes at the Super Hero Customs website or see them in action in the trailer below.

Unfortunately, these tricked-out bikes aren't available for sale. Residents of Australia and New Zealand can enter to win one by voting for their favorite design on their website, but fans in the rest of the world are out of luck for now.
