Registration numbers forcycles is not a new idea, it worked well in Cambridge in the 1950s where all undergraduates were required to have one and at a number of schools in the 1960s and 70s. So why is it such a big deal to ask cyclists to invest a small amount in a licence and an identifying number now?

The rest of us have paid out hundreds of thousands of pounds to adapt roads, cycle lanes and the like to suit this minority and still they bleat on about unfair treatment on the roadsby car drivers. Many seem to be riding on the pavement with headphones on anyway.

Having a registration number, a licence and some sort of insurance will help slow the number of thefts too, I would have thought.
