I now have new Purple Sky designed sail shaped flags from Traumvelo in Germany.
I purchased a yellow and purple large size flags plus a medium size orange flag for a trailer. The large size flags do not seem to be disproportionate to the size of the trike.
These flags have large sections of reflective material to make them visible in headlights. For those who can't see large yellow and purple areas flouro green and orange ribbons with more reflective material are attached to the top.
The material of these flags is better than the cloth reinforced plastic of my previous flag.
I also purchased some mounting adapters because the flagpoles are thicker than the Greenspeed mounts accept. The reduced diameter was too loose so I ended up making a taper on the ends so that they sit deeper into the mounts. This has the side effect of the adapters being locked into the mounts so their is less chance of loosing a flagpole.
There was very little flapping noise from the flags although the very flexible poles slapped together during cornering.
They certainly makes the trike more distinctive.
