What if your walking on the towpath with a hearing problem. Or have headphones on/in. No amount of bell ring makes a blind bit of difference. Are you saying we should keep looking behind us every couple of seconds to step out of the way, which I do to protect myself. (Hard of hearing) And why should you have to jump for your life when people hear a bell. I too have a bike which I ride on the towpath but don’t ring my bell straight away. First I make the brakes squeak. If that doesn’t work l peddle backwards. If no response I ring the bell. If by then they have not herd me I say bike coming. I find the more gentle approach is much appreciated rather than ding ding get out of my way approach. I’m not against cyclists using the towpath as it’s there for everyone but i dread the coming of the speeding ones on a mission.
