H-bike Rental System / Hydrogenbike rental system

H-bike Rental System

"Hydrobike" uses hydrogen to make electricity in order for the bike to run.
And the hydrogen in the bike is recharged in the rental system.
The hydrobike folds itself in the storage of the rental system.
Its computerized program both manages ins and outs of the bikes, and secures them by monitoring 24-7.
This new concept of rental system has its clear purposes:
convenience(sufficient transportation), efficient use of limited space available,
prevention of environmental pollution.
