a pair of 225cm DH race skis strapped to the top tube, sticking out both ends.
If scooter riding can be included, while living in Bermuda I've scootered with:
a bag of golf clubs between my legs
in a wetsuit, wearing my bcd, with tank strapped to back and resting on passenger seat, mask around neck, fins between legs
a 16 foot spinnaker pole resting on the bars and nestled under my arm, jousting style, with red rags front and back. Wouldn't want to be unsafe you know.
