This high-tech e-bike warns you if a car zooms into your blind spot

If you’re riding a new electric bike and begin to make a turn or change lanes when it isn’t safe, the bike’s handlebar will buzz a warning in your hand. Like some cars, the bicycle has blind-spot detection, one of a suite of features designed to make it as safe as possible on the road.

“We had a dream of building the world’s most advanced and safest bike,” says Nilesh Bothra, CEO and cofounder of Calamus, the Mumbai- and Berlin-based startup building the bicycle, called the Calamus One, which is currently crowdfunding on Indiegogo, starting at $1,997 .
