Sometimes you don’t have the option of calling for an ambulance. That’s when something like the Zambulance comes in. Made by Zambian bicycle manufacturer Zambikes, this modified bike trailer is outfitted with a mattress and a tent-like curtain to offer shelter from the heat and rain. What used to be a 2-3 hour ox cart ride can now be accomplished in as little as 30 minutes. [via gizmag]
