Harley Davidson + Marvel= Super Hero Bike
Don't get overly excited this is just a marketing coup for Australia and New Zealand. The bikes are just designs for now that are part of a promotional campaign. People vote and then could win a one of custom. Honestly, we think the Captain America bike makes sense as good ole Captain is not loaded with superpower but he does ride. Spidey on a motorcycle? Whatever.
Personally, we would have made the Captain America bike more of an all terrain vehicle, like the scrambler they designed for Spiderman, but more bad ass. See for yourself.
