he problem: Biking to work or school requires a lot of psychical strain and isn’t realistic for those needing to wear business attire or travel long distances.
The solution: Smartwheel is a motorized bike wheel that can be used on any existing bike. Replacing one of a bike’s wheels with a motorized one would effectively eliminate a lot of the downsides of bike commuting: the physical effort, the time constraints, the varied terrain. The wheel can allow a bike to reach about 20 miles per hour, and it can also synch up with a smartphone to protect against theft and monitor the rider’s speed and distance.
