My Brompton is ticking is that normal? Hub gear noise 

A question we often come across / get asked is … my rear wheel is ticking a lot - is that normal
The simple answer is (normally) yes
It happens to a different extent based upon which gear is being used and if you are pedalling or freewheeling
Gear 3 makes the most noise
