It would be great to find out what people have thought of for use as unconventional accessories.
I have three that I use every ride and maybe you do too.
Shoe dryer. I use a shoe/boot dryer to dry my shoes because they fill up with sweat every ride. Where I live things don’t dry outside so using the dryer means my shoes get dried and don’t stink as often.
My reaching stick. I drop stuff. My reaching stick saves me having to yell for help. (I have a back up reaching stick in case I drop my primary reaching stick.)
Dog training pads. No more lake of sweat.
If you have an out of the box accessory idea please share it.
