This walker carrying bracket fits neatly into the accessory acceptor tube below the seat on most makes/models of mobility scooters. It allows you to carry either a walking frame, a rollator or even a tri-walker on the back of your scooter.
 
These are great if you are able to walk short distances aided as you can park up and have a little exercise.
 
These brackets require no tools to assemble but may require cutting down slightly as they are universal fitting.
