Isn`t it a shame that one has to "rubbish" a new bike in order to prevent it being stolen. Before I retired, I did not use a bike much, and then only for nipping into town. My approach was to always have a bike, but one which whilst being reasonably roadworthy, was of poor cosmetic appearance. At the local tip, you could choose from about ten to twenty bikes, at a fiver apeace.
These had been discarded by previous owners because they were considered worn out. Most examples could be restored to working order in half an hour. Oiling the chain and inflating the tyres was usually all that was needed.Perhaps, if you were less fortunate, a puncture would need mending. So for a fiver, you could buy a decent bike that had previously been "Professionally Rubbished". Sadly, the tip no longer sells bikes. Elf and Safety, and all that.
Going back to Flecc`s long hill. We talked about a cutting, and an escalator. One has to wonder if a tunnel might be cheaper. Much less spoil to remove. I believe that an old railway tunnel has been converted to cycle use in Bristol, and there is a cycle tunnel beneath the Clyde in Glasgow. Also, it doesn`t rain in a tunnel.
