I used double sided velco to attach it to the stem steerer thingie on my bent. Pretty hard to deploy quickly enough. I generally dismount and use the bike as a shield walking
On an upright the dog gets your leg, on my bent the dog's teeth and my face are at eye level and it is terrifying to be honest. A Rotweiler almost got me as did a Pit. I did not have time to do anything other than swerve into traffic and across the road with the Rotweiler. Owner says, "Oops, sorry"
