The idea began in 2010 when a Copenhagen fertility clinic first started using tricked out cargo bikes to deliver sperm to it's clinics. Now, Seattle Sperm Bank has joined the wave, purchasing a sperm-cycle of their very own. Carrying up to 20 vials of semen in a liquid nitrogen cooled tank, the modified BULLITT cargo bike from Danish company Larry vs Harry serves to promote green solutions to transportation and doubles as a great promo vehicle.
