Bicycle Courier Bottle Cage Mount

This was an open brief project. The brief I set myself was to make it easier for bicycle couriers to stay hydrated whilst on the move.
Bicycle couriers tend to ride fixed gear bikes which have no bottle cage mounts.
The final product had to be robust and lightweight to stand up to daily abuse whilst not being to heavy and bulky.
