Last year, when I bought our Novara Safari bicycles, a priority purchase was a lock or some other security device.
The fact a security device to protect a bicycle is a requirement to keep it from being stolen pisses me off.
This got me to thinking. Almost every person I know, who has owned bikes, has had one or more stolen. In the past I have had three bikes stolen from me and all were locked to prevent theft. So thus began a new research project.
