Ford unveils a bike that pedals for you when you get out of breath

U.S. carmaker Ford has moved from four wheels to two as it unveiled a connected bicycle with vibrating handlebars to tell you when to turn.

The so-called "e-bikes" have a 200-watt motor and a battery that kicks in to help propel cyclists along to speeds of up to 25 kilometers per hour. This kicks in when a users' heartrate goes above a certain level – that way you won't arrive at your destination in a sweaty mess.

The MoDe:Me and MoDe:Pro bikes are only at the concept stage with no confirmed date for launch. However, the company plans to offer them at an "affordable" price.

The bikes are designed to work with an app on the iPhone 6 called MoDe:Link. A user will type in their destination and the app finds the best route as well as cycle-friendly routes. The iPhone can be docked in the Pro model of the e-bike and handlebars vibrate to indicate that a turn is coming up.

MoDe:Me will be is foldable and designed for commuters to take on trains and in cars in busy urban areas. The MoDe:Pro is designed for businesses and comes with a storage space on the back. Both bikes are equipped with a rear-facing sensor to tell riders when a vehicle is approaching from behind. On the vibrating handlebars are indicators that light up depending on which direction the rider will turn.

"Being able to seamlessly move between cars, buses, trains and e-bikes and react to changing traffic situations can make a big difference both for commuters and for those delivering goods, services and healthcare," Ken Washington, vice president of Ford research and advanced engineering, said in a press release.
