We know of two stolen this year from people on this site and I heard of another stolen in Tucson on the BROL message board. The one in Tucson was parked outside a shop. This has me very concerned. For many of us, the trike is worth more to us than our cars. For some, it replaced their car.
But, the site also states that most stolen bikes are never reported.
Here's another site with tips on how to recover your stolen trike.http://www.bikeshepherd.org/stolen-bike-recovery.html
. I like the alerts from all the different sites where the trike could be sold. I know I'm going to register mine everywhere I can before it gets stolen.
