From Cynthia (an avid TravelScoot fan who does not work for WheelChairGear OR the company that makes these products):
For those of us who have older TravelScoots and need a place to carry the tools this little Day Cruiser Mini Pack does the job nicely!
You can get them from http://www.wheelchairgear.com/ . The Day Cruiser Mini Pack is $19.95 USD, and the No-Slip Grip-Clip is $9.95 USD.
Here are various pictures of it so you get an idea of how you might use one to carry your TS tools or emergency what not.
I also love the No-Slip Grip-Clips from WheelChairGear too. I am using one of them in all of the photos below to clip the Mini Pack too.
