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

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).
