Old Bike frames wanted (Preferably BMX or child)

[EasyCrank]

Hey everyone,

I'm currently in the process of building a new bike shed at home and wanted to give it a fun quirky edge.
The plan is to concrete 3-5 bike frames in a row to act as the bike stands/locks. If anyone in the Bristol/South West area happens to have an old bike frame lying around that your looking to just get rid of I'd happily collect it from you.

Thanks all
