Biking keeps you fit. It is a clean and green way to get to work it you live close enough. Also, it’s cheaper than driving a car.

Biking has so many advantages, but why aren’t there more bikers on city roads? According to a survey, the number one reason is the worry about road safety.

Sharing the road with cars can be dangerous. Omar Bakhshi experienced this when a car knocked him down, which had bad effects on his taste and smell for life. Bakhshi realized that what happened to him wasn’t unusual.

Because bikers often experience dangers with cars, Bakhshi set out to make roads safer to share. He started a company, Tether, to improve safety conditions for city bikers.

Tether’s invention is a smart sensor (传感器) that goes on a bike’s handlebars (把手). As the biker rides through the city, the invention makes a “safety zone (地带)” of lights onto the road. These lights will make cars pay attention to the rules of sharing the road. If cars get too close to the biker’s personal spaces, the lights will start flashing.

What makes Bakhshi’s invention different is its smart features (特点). Tether’s tool collects data (数据) from these biking accidents. The data is organized into a central database and can be used to choose which streets are safer for bikers.

Not only can bikers choose a better way to avoid heavy traffic by using the data, but Bakhshi plans to share the data with the government.

Walking, biking, driving and public transportation all have different advantages and disadvantages. When all road users can share the same level of safety knowledge, everyone can get where they need to go quickly and safely.
