phoenix_zhu / bicycle locks


Nowadays global warming has posed a serioud threat to survival of humanity.
In daily life,try to fulfil the concept of reduce,reuse and recycle as much as
one’s ability allows and the concept of zero carbon emmission.First of all,a lot
of greenhouse gas is produced by car.But we can not give up our mainly
transportation,so we can have more use of bicycle.Locking bicycle is a very
annoying thing,so I think this might help.
