The Dublin Bikes scheme has been one of the most succesful developments to occur in the city in recent times. Launched just over 4 years ago the scheme has exceeded all expectations with over 5 million rentals taken place since its launch and the scheme is widely considered to be one of the most successful in the world. Currently there are 550 bikes and 44 stations located around Dublin, and there are additional plans to expand the scheme east to the docklands and west to Heuston station, adding 58 stations in total and bringing the number of bikes to 1,500.
However, one issue facing the further expansion of the scheme is the general availability of suitable street space for setting up proper bike storage infrastructure. A similar problem faced the bike scheme in Japan where available space was at a premium due to overcrowding. To resolve the space problem the Japanese developed an ingenious earthquake resistant underground bike parking system which can be seen in action on the video clip below:
