3. Overview: Design Constraints
Budget: $1000
Carrying capacity: 180 lbs
Maximum weight of bike frame: 20 lbs
Rider height: 5’1”
Ideal length with skis: 4 ft

4. Overview: Mission
Design and manufacture a low cost alternative mountaineering descent assist.
The mountaineering assist must be convertible as the skis used in the assembly are to also be used during ascent.
The descent assist must be portable (lightweight and small enough to be transported by from the base point, to a point below the summit).
