Are these utilitarian vehicles used for sports? According to El Correo de Andalucia, "This service as transport already has 60,000 users per day which means that 6.6% of all journeys are made in the city are by bike." Are there minors using them? According to SEVici, 14 to 18 years-olds are allowed to use the system, but only with written permission from parents or guardians.
Advertising has always been intertwined with 3rd generation bike-sharing. The first systems were paid almost solely by advertising revenue, either off-site or on the bikes. Then different business models distanced the bikes from advertising. Now there is a strong movement for "peddle while one pedals" in bike-sharing. As these systems grow, it is becoming evident that income from advertising is a necessity to pay for the increasing cost to maintain the systems.
The Bike-sharing Blog and the bike-sharing world will be watching how this controversy unfolds. Since we all know that bike-sharing systems are created to serve the public, or in this case should we say "cervesa" the public, whether they are with or without advertising.
