Radical electric bike concept saves on space

Yuji Fujimura has taken the bicycle design manual and thrown it to the wind with his concept Electric Bike Version 2. Ditching the popular and familiar diamond frame design, Fujimura has opted for a flat solid box on wheels where the handlebars, seat and pedals fold away flat to help squeeze the bike into tiny parking spaces.
Parking bicycles can be a troublesome affair if you're in an area where an awful lot of people use two wheels to get around. As electric bikes grow in popularity the issue is unlikely to improve. The Electric Bike Version 2 concept from Yuji Fujimura takes a slightly different approach to bike design which also offers a possible solution to overcrowded parking woes.
The concept bike would have pedals for human propulsion, which could both be set at the lowest position when traveling under electric assist. The upright seating position appears similar to that of more familiar diamond frame bicycles but that's where the similarity ends. As you can see from the gallery examples, Fujimura has gone for a flat, solid body box design with all the electronics and lighting enclosed within the housing and solid wheels.
Being a concept design, details on the electrics are limited to revealing that the designer proposes using a Li-ion battery, an electric rear wheel hub motor and that the bike would include a charging compartment for mobile phones, laptops, MP3 players and so on. The handlebars, seat and footrests/pedals fold away flat so that the flat, wheeled box can slide into the slimmest of parking spaces.
Whilst the Electric Bike Version 2 concept is imaginative and aspects of it make a lot of sense, just how stable the bike would prove in strong winds with nowhere for gusts to go except to slam against the solid body is cause for great concern, especially when cornering. Fold-away handlebars, seat and pedals to help squeeze the two-wheeler into tight parking spaces though - now there's a good idea.
