I think people more noticeable in a wider vehicle than flat little bicycle…
those flags that stick out at side and encourage cars to give passing space of 18″ or so are probably a good idea.
part of me would maybe go for a normal bike that fits on cycle paths better though? not sure.
main thing wear light colours, sometimes get cyclist all in black, no lights and then they complain when you nearly walk out in front of them, got sworn at by this stupid girl. Felt like saying had seen cyclist knocked off and slid down road on his face, would she want the scars and skin grafts?
important to get a bell too. I’m happy for people to ride carefully on pavement but if they sneak up behind you can give nasty shock, much better to have a little bell to gently warn you, it’s courtesy cos you have right of way.
