Nordisk Cryobank, one of Europe’s leading sperm banks, was looking for eco-friendly ways to transport sperm samples to fertility clinics around Greater Copenhagen when it hit them--a sperm bike! Or more precisely, the “Sperm Bullitt”.

Not only is the delivery bike a moving billboard, but it contains a cooling compartment, conveniently located inside the head of the giant sperm, to safely transport sperm samples; all of this with zero emissions.

The Sperm Bullitt has done a great job generating awareness, as Nordisk Cryobank is constantly looking for new donors to help childless families. The bike's comical appearance has no doubt made talking about the process of sperm donation a lot easier. People regularly stop the bike to take pictures and ask about its purpose.

With its tail included, the bike is 2.9m long and weighs 50kg when loaded.
