I hike and bike so also wanted the option of a backpack to carry gear. I got the folding Mod and it is sturdy. It was a trade off with adding 5 oz.
Folded with the stock coil the width is 17" due to control unit.
I am making this more compact, ordered the Mod to fold down the control unit. Being 5' tall, I like a smaller packs, and the 17" W wasn't fitting as well as hoped in what I had, and didn't want to go with a pack that bounced on my rump. 🙂
I"ll post more pics when new mod is installed
HH all!
