Don't mix it in your bathtub. Don't spill concrete on anything that belongs to your landlord. If the bike is valuable, don't trust this setup, because an organized thief with a friend could pick it up and walk away. Why not just keep the bike in your bedroom?
Thank you for the that advice. I think 2 bags is what I will go with. I am going to submerge chicken fence wire to reinforce it so that picking chunks of will be hard and take longer. I know this is not completely theft proof but I am willing to put the hours in to make it as difficult as possible. I have invested in a Abloy lock 362 which is one of the best padlocks available and I will be getting either a 16mm or 19mm link chain that is guaranteed against hand bolt croppers.
My bike was stolen from my yard and they cropped a chain with bolt croppers. I'm sure it was not a professional thief, just someone who had spotted it and planned the theft. It wasn't at all a high-end bike but was custom built and was an average amount of cash. I had not realised but the bigger chain that was secured to and immovable post had been tampered with because they ripped the nylon cover and is looks like they use a hacksaw because there were some hair line scratches - barley scratched at all.They had covered the chain with gravel so I did not notice. It must have been a few weeks or months before the next attack because there was a HUGE spider set up home with a nest in the ripped hole. The chain cropped was a lot smaller than the chain attached to the post and the smaller chain was attached to that and then attached to the bike.
I may just keep the new one it in my bedroom and get is insured.
