Nothing wrong with riding brakeless; it's a different style of riding and may require more skills and experience. Alright, in all seriousness riding brakeless in a competitive situation is not necessarily commendable, nor sensible, thus fitting a brake for racing or training full whack on public roads, particularly if/when riding in a group, does make good sense and will more than likely be a requirement should you join a club. Do what's right for you, but be careful. Actually, considering your age, do what your mum tells you to.

I agree, nothing wrong with brake less, I rode brake less before I got trained as an instructor, however it's more about putting even more unnecessary stress on your legs if he want to ride to Brighton which he seemed to be making a mountain out of a molehill.
