1. Bicycle Safety System We got your back David Korobov – B.S. Computer Engineering – Dec. 2016 Zeyuan Yu – B.S. Electrical Engineering – Dec. 2016

2. Problem In 2013, over 900 bicyclists were killed and nearly half a million injured in collisions Crash related injuries result in $10 billion worth of losses in medical expenses and productivity 42% of all bicycle-vehicle collisions are rear-end collisions Bicyclists face a higher risk of crash related injury and death than drivers Source: Centers for Disease Control and PreventionCenters for Disease Control and Prevention

3. Solution Camera located at the back of the bicycle to monitor approaching cars Smartphone application to use GPS location to perform statistical analysis using past data Waterproof case for the camera and handlebar phone mount Smartphone displays notification for risk assessment

4. Market 103.7 million Americans rode bicycles in the past year (34% Total Population) 14.5 million ride their bicycles almost everyday 52.1% are worried about being hit by a motor cycle 14.5 * 52.1% = 7.3 million potential (US) market size 103.7 * 52.1% = 54.0 million maximum (US) market size Only 17.2% feel more safe riding a bicycle today than 5 years ago Source: U.S. Bicycling Participation Benchmarking Study Report by Breakaway Research GroupU.S. Bicycling Participation Benchmarking Study Report

5. Competition A few rearview bike cameras are currently on the market None of them connect to a smartphone for a statistical risk assessment None of them has a notification mechanism Cost: nearly $200

6. Cost Camera module: $20.7 Cables: $3-4 Handlebar mount: $15 MCU: $16 Li-Ion battery: $25 Total: ~$80 We anticipate significantly lower costs upon mass production
