Now the urban density is getting higher,but
accommodate bicycle of public space is
getting more and more small,the question
is how to put the bicycle in the city orderly
and reasonable and to save space. The
handle lock solve the problem very well.
When the rider parking the bicycle, only
need to bend the handle to lock the bicycle,
and the width of the bicycle will be narrow
than before, it will save a lot of space when
you park the bicycle side by side or against
the wall.
