I've been wanting a way to carry a tall walking stick or my walking cane on my Spyder without lashing it across the seat. The walking stick is over 5 feet long so that's not practible.
I design and and fabricated a holder that is attached to the trailer hitch. The end of the stick/cane goes in the holder. A piece of parachute cord puts tension and holds the stick/cane so it doesn't leave the Spyder while under way.
The holder is made of stainless steel sheet.
