Problem Statements
Problem Statement 1
In 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air. Riding a bike can greatly improve upon our pollution output, but bikes can be a hassle sometimes, with faulty chains and other parts.
Problem Statement 2
Of the 318.9 million people in the United States, 103.7 million Americans ride bikes. The power to move these bikes is applied in the chain, where the motion and sprockets are controlled. Sprockets and chains account for 34.1% of bike related injuries. Currently, the process of fixing a faultionary chain or sprocket, is not a permanent fix and most frequent bikers experience chain problems multiple times.
Problem Statement 3
Biking stores and forums are constantly swamped with people complaining about the frequency of their bike chain skipping or falling off, and ways to fix it. There are hundreds of different bike chain configurations like the chain guide apparatus by Robert L. Barnett. In 2014, 44.2 million people in the United States rode bikes, which means that many people were at risk of serious injury or death due to a bike chain malfunction, which happens
