We need a portable storage solution for our free kids bikes

At redemptive cycles we don't believe in charging for kids bikes, so we give them away! We recently lost our storage space for our kids bike pile, and because space is very limited in our shop we've been forced to keep them in our back alleyway. Despite the ongoing need for a storage unit the bikes have not been stolen and in the past few weeks we've been able to send home six happy kids on free bikes. If you can help in any way or know where we can get a free portable storage unit please let us know.
