This is a great idea with obvious immediate use. Will require some thought and debate, which is perfect for GrabCAD Teams. We're excited to see this prototyped!
Very cool idea but will require a total redesign. Also tough to imagine a great use-case. With the weight and complexity of this product, one might just buy a portable bike pump and take the ~10 seconds to pump tires.
Simple, useful, easy to make. Easy to test. But, a few key issues took this from first to third place. Are all bike handlebars the same diameter? Can you actually put keys into handlebars or are they too small?
Neat design, though it might be difficult to design the electric components and test the overall effectiveness of the final prototype. Not to mention more expensive.
