Fold up bikes are usually really dorky looking. Not the Cube concept bike called the Urban Street. Front lights are built in to brake levers and the front wheel hub will turn on lights when needed.
It is fantastic when unfolded and ready to ride and when it is folded, it's small enough to carry to your walk-up or stash in the closet.
Implications - Consumers are looking to purchase products that minimize the amount of space needed for storage. Concepts such as this Cube's Urban Street bicycle are highly popular as they are able to solve storage problems while still maintaining the quality of the original, but not storage-friendly product.
